Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes .
The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic subjects like maths and reading.The studies appeared between 2007 and 2013.They included more than 55,000 children,aged 6 to 18.
Amika Singh:“Based on the results of our study,we can conclude that being physically active is beneficial for academic performance. There are,first,Physiological explanations,like more blood flow, and so more oxygen to the brain.Being physically active means there are more hormones(荷爾蒙)produced like endorphins(內啡肽).And endorphins make your stress level lower and  your mood improved, which means you also perform better.”
Also,students involved in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work.
The study leaves some questions unanswered,however.Ms.Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies .
Also.they were mostly observational studies.An observational study is where researchers do not do controlled comparisons.They only describe what they observe.So they might observe a link that students who are more active often have better grades.But that does not necessarily mean being active was the cause of those higher grades.
The researchers said they found only two high - quality studies.They called for more high-
quality studies to confirm their findings.They also pointed out that “outcomes for other parts of the world may be quite different. ”
Still,the general finding was that physically active kids are more likely to do better in school.Ms.Singh says schools should consider that finding before they cut physical education programs.Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine.
小題1:The passage mainly tells us that ____
A.a research on physical education has been done by the researchers
B.there exists a possibility that physical activity leads to higher grades
C.the amount or kind of activity directly affects academic level
D.the research shows that the children aged 6 to 1 8 don't do sports
小題2:Which of the following is TRUE?
A.Being mentally active is good for academic subjects.
B.The more hormones you have,the more stressed you will get.
C.They have found many high-quality studies to prove the research.
D.The educators in the research think studies,not exercise,mean much to students.
小題3:The underlined sentence in Paragraph 7 probably means ____.
A.good marks result from high-quality study
B.findings probably vary in different areas
C.physical activity will spread all over the world
D.academic performance depends on the surroundings
小題4:What's the purpose of writing the passage?
A.To call our attention to the sports at school.
B.To introduce all types of physical activities.
C.To represent the academic performance.
D.To improve students' health .

小題1:B
小題2:D
小題3:B
小題4:A

試題分析: 本文講的是體育鍛煉能提高學習成績嗎?
小題1:B 細節理解題。根據第一段提到Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes最近我們講述了關于上學時間更長能夠幫助學生在智力測驗中得到更高分數的一項發現,這是針對挪威青年男子的一項研究。現在其它研究表明,體育鍛煉可能幫助學生在功課上做得更好,所以選B項。
小題2:D 細節理解題。根據第五段提到The study leaves some questions unanswered,however.Ms.Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies然而該研究還留下了一些未解之謎。辛格女士說,無法確定是運動量還是運動類型影響到學術水平的提高。因為這些研究之間存在差異,所以D項正確。
小題3:B 細節理解題。根據第七段提到The researchers said they found only two high - quality studies.They called for more high-quality studies to confirm their findings.They also pointed out that “outcomes for other parts of the world may be quite different.研究人員表示,他們只發現兩項高質量研究。他們呼吁進行更多高質量研究以確認他們的發現。他們還指出,“世界上其它地區的結果可能大不一樣,所以選B項。
小題4:A 細節理解題。根據最后一段提到Still,the general finding was that physically active kids are more likely to do better in school.Ms.Singh says schools should consider that finding before they cut physical education programs.盡管如此,總的結論是,喜歡運動的孩子更容易在學校表現更好。辛格女士說,學校應該在削減體育課之前,考慮一下這一研究發現,所以選A項。

According to body language expert Robert Phipps,the way people sleep at night actually determines a lot about the type of personality they have.Phipps has identified four sleeping positions that affect personality.
Phipps found that worriers,those who stress the most,tend to sleep in the fetal(胎兒的)position.He found that this is the most common bedtime position,with nearly 58 percent of people sleeping on their side with knees up and head down.The more we curl up(蜷曲),the more comfort we are seeking,according to Phipps.
The second most common position is the log.Sleeping with a straight body,with arms at each side,as if they are standing guard at Buckingham Palace,indicates stubbornness,and these people(the 28 percent who sleep this way)often wake up stiffer than when they went to sleep.
“The longer you sleep like this,the more rigid your thinking is and you can become inflexible,which means you make things harder for yourself,”according to Phipps.
Yearner(向往型)sleepers are next on the list.About 25 percent of people sleep in this style—on their side with arms stretched out in front,looking as if they are either chasing a dream or perhaps being chased themselves.Yearners are typically their own worst critics,always expecting the best results,explained Phipps.These people often wake up refreshed and eager to face the challenges of the day ahead.
Perhaps the most peculiar(奇怪的)of sleep styles is the freefaller position.This sleep style makes up 17 percent of the population.They sleep face down with arms stretched out.These people,according to Phipps,feel like they have little control over their life.Not only is this the strangest of sleep styles,but also the least comfortable,and people may wake up feeling tired and have no energy.
In conclusion,Phipps has only one more thing to add:“A good night's sleep sets you up for the following day and our sleeping positions can determine how we feel when we wake.”
小題1:Which of the following is the best title of the passage?
A.A Good Night's Sleep Sets You Up for the Following Day
B.Your Personality Depends a Lot on How You Sleep at Night
C.How You Sleep at Night Affects What You Do the Next Day
D.Which Sleeping Position Helps You Sleep Comfortably
小題2:Which of the following pictures is the fetal position?

小題3:The underlined word“rigid”is closest in meaning to “________”.
A.stubbornB.flexible
C.comfortableD.strange
小題4:Which of the following shows the structure of the passage?
CP:Central  P:Point Sp:Sub?point

Most people know precious gemstones (寶石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.
Beneath the surface of a gemstone, on the tiny level of atoms and molecules(分子), lie clues (線索) to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.
Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.
To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles(微粒)called electrons separate from atoms.
The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements(元素)produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.
In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.
Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.
小題1:We learn from Paragraph 1 that __________________.
A.an emerald and a ruby are names of diamonds.
B.it’s not difficult to tell where the gem was mined.
C.appearances help to identify the origin of gemstones.
D.diamonds from different places may appear the same.
小題2:Why did the U.S. government pass law that requires companies selling gemstones to determine the origins of their stones?
A.To look for more gemstones.
B.To encourage violent civil wars.
C.To reduce the trade in blood minerals.
D.To develop the economy.
小題3:Which of the following facts most probably helps McManus and her team in identifying the origin of stones?
A.Heat can turn ice into water or water into steam.
B.Gemstones from the same area produce similar light patterns.
C.Laser can changes a miniscule part of the gemstone into plasma.
D.Materialytics has already collected patterns from thousands of gemstones.
小題4:From the last two paragraphs, what can be inferred about the laser technique?
A.It is ready for commercial use.
B.People can use the new tool to find more gemstones.
C.It can significantly reduce the gemstones trade in blood minerals.
D.It will bring about a revolutionary change in identifying the origin of minerals.
小題5:The author wrote this passage mainly to ________.
A.tell us how to identify the origin of diamonds.
B.introduce a laser technique in identifying a stone’s origin
C.prove identifying the origin of gemstones are difficult
D.attract our attention to reducing trade in blood minerals

This summer, you can experience all of these things, and more. All you need is an Internet connection and your imagination.
A recent study by the Kaiser Family Foundation found that kids spend an average of 1 hour and 29 minutes online each day. Many kids like to use that time to chat with friends, play games or check e­mails. But the next time you get on the Web, try exploring the world instead. “With the Internet, you can go back 11,000 years in time, or go 11,000 kilometers across the planet.” said Russell, Web search expert of Google. “The whole scope of history and the world is open to you.”
There is a wealth of information to be found online. For example, if your family is going on vacation somewhere,do a quick online search on the area before you even get in the car. “What's the background of the place; what's the history?” says Russell. “I like to tell my kids, ‘Whenever you have a question, whenever you have a doubt, search it out.’”
Ready to launch a virtual journey of your own? Here are a few starting points to get you thinking and to help you on your way. You can invite your parents along for the ride, too. Always ask for permission before downloading programs and software onto your computer. And check with a parent or an adult before visiting a new Web site.

Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have        how difficult it is to write a        children's book.  Either the author has aimed too     . , so that the children can't follow what is in his (or more often, her) story,        the story seems to be talking to the readers.
The best children's books are        very difficult nor very simple, and satisfy both the     who hears the story and the adult who         it. Unfortunately, there are in fact       books like this,       the problem of finding the right bedtime story is not        to solve.
This may be why many of books regarded as        of children's literature were in fact written for      . “Alice's Adventure in Wonderland” is perhaps the most        of this.
Children, left for themselves, often      the worst possible interest in literature. Just  leave a child in bookshop or      and he will more  willingly choose the books    in an imaginative way, or have a look at most children's comics ( 連環畫 ), full of the stories and jokes to which both teachers and right-thinking parents     .
Perhaps we parents should stop trying to persuade children into        our taste in literature. After all children and adults are so       that we parents should not expect that they will enjoy the      books. So I suppose we'll just have to compromise(妥協) over that bedtime story.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection. ,科Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement(侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties(版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because _____________.
A.people did not know how to put out the fire
B.Elias Howe thought Thimonnier had stolen his invention
C.the sewing machines was couldn’t work finally
D.workers who feared the loss of their jobs to a machine set fire
小題2:Which of the following is NOT TRUE according to the passage?  
A.Singer is an American inventor and manufacturer.
B.The Singer sewing company became more practical.
C.The foot treadle helped to make the sewer’s hands free.
D.Singer made improvements to the design of sewing machines.
小題3:Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?
A.Because the judge was against Singer for his surly attitude.
B.Because Howe had already patented the lockstitch used by Singer.
C.Because Singer had borrowed money from Howe and never repaid it.
D.Because Singer and Howe had both invented the same machine.
小題4:Which of the following would be the best title for this passage?
A.A Stitch in Time Saves Nine
B.The Case between Howe and Singer
C.Patent Laws on the Sewing Machine
D.The Early History of the Sewing Machine

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步機). Sometimes they wore running shoes. Other times they ran barefoot (赤腳).
Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.
小題1:What’s the main idea of the passage?
A.Walking in high heels could cause less serious effects than running barefoot.
B.Two new discoveries encourage people to run in high heels.
C.Running in shoes is partly good to runners.
D.Two new studies prove running without shoes is beneficial to runners in most cases.
小題2:Which part of our body could be injured if we run in running shoes?
A.Toes.B.Hips.C.Feet.D.Legs.
小題3:What can we learn from the passage?
A.The way that we run by landing on the front or middle of our foot could avoid damaging our heel.
B.We should start running barefoot in no time.
C.Running in modern running shoes could cause more serious effects than running in high heels.
D.We won’t be injured if we run barefoot.
小題4:What is the writer’s attitude towards the use of the modern running shoes?
A.Persuasive.B.Negative.C.Objective.D.Supportive.

Bad teeth may be painful and it’s getting worse without treatment. They can even ruin your life. Illness of the teeth can find its way into the blood system. This can increase the chances of a heart disease or other illnesses.
Experts say good care for teeth should start at birth. Mothers’ milk is the best food for the healthy development of teeth.
But dentists say a baby’s mouth and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, give him only water.
When baby’s teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. Young children often eat toothpaste (牙膏) when they brush, so they should be carefully watched when they brush their teeth.
Parents often ask what effect thumb sucking (咬手指) might have on their baby’s teeth. Experts generally agree that this is fine early in life. Most children stop sucking their thumbs by the age of four. If it continues, parents should talk to their children’s dentist or doctor.
Dentists say children should have their first dental visit by the time they are one year old. They say babies should be examined when their first teeth appear usually at around six months.
小題1:Why should people pay attention to teeth problems?
A.They can cause other illnesses.
B.They will bring bad luck.
C.They will bring the family much trouble.
D.They usually last a long time.
小題2: According to the writer, baby’s teeth should be protected from the day ______.
A.he begins to speakB.he has his first tooth
C.he was bornD.he is fed with bottle milk
小題3:The underlined word “it” in Paragraph 5 refers to “_____”.
A.toothacheB.parents’ troubleC.thumb suckingD.experts’ advice

Having spent two and a half years in China over several visits, I don’t remember ever going through a phase we in the United States call “cultural shock”. This period of difficulty in adjusting to a new culture would probably have set in during my semester at Peking University. Of course, this is not to say that I didn’t notice any differences between the American and Chinese cultures upon my arrival at Peking University, I did notice the differences. Looking back, I remember one of the first differences I noticed: Chinese universities are surrounded by walls.
To an American, this is one of the most striking aspects of a Chinese university which immediately sets it apart from an American campus. Having grown up in the United States, I had never seen a university surrounded by high, cement(水泥) walls. My idea of a university, based on having seen scores of them in different states of the U.S., was a place of life and learning, an inseparable part of the community in which it was located, open not only to the students of the school itself, but also fully accessible to students from other schools and to the broader public.
My idea of a university was that it was a center of cultural life, a resource for the entire community. In all my twenty-one years, it had never occurred to me that a school would have a wall around it. Walls enclose and separate; schools expand and integrate(合并). The very idea seemed fundamentally incompatible. I asked a Chinese friend if all Chinese universities have walls around them. “You know, I have never really thought about it. I guess so. I guess all Chinese schools have walls around them, not just universities.” “Why?” I asked, “What’s the point?” “I don’t know. To protect us, I suppose.”  “From whom?” “I don’t know. Don’t you have walls around your schools in the United States?” I thought carefully before answering. “No, I’ve never seen or heard of a university encircled by a wall.” My Chinese friend seemed puzzled. Walls around schools came to strike me as more than just an architectural difference between the United States and China. As China continues to open up to the outside world, these walls seem increasingly out of place.
小題1:The author felt strange about Chinese culture when he ___________.
A.studied in Peking University
B.talked with his friends about the walls
C.experienced the “cultural shock” at his arrival
D.spent two and a half years in China over several visits
小題2:In the author’s opinion, a university is a place ___________.
A.where only students can come to study
B.which is similar everywhere in the world
C.that should be surrounded by high cement walls
D.that is an inseparable part of and a resource for the community
小題3:What does the underlined sentence in the last paragraph probably mean?
A.The two ideas are fundamental.
B.The two ideas are basically different.
C.The two ideas about “school” and “wall” are suitable.
D.The two ideas about “school” and “wall” are conflicting.
小題4:What did the author’s friend feel about the walls around universities?
A.He thought it a good idea to have walls encircling schools.
B.He was shocked that American universities are not enclosed.
C.He thought they were necessary to protect students from being hurt.
D.He thought the difference between two countries is only architectural styles.
小題5:We can infer from the passage that the author thinks _____________.
A.walls are really useful in the universities
B.he can never really understand the Chinese culture
C.Chinese universities should work as public scenic spots
D.walls around the universities are inappropriate in an open China
