Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知識庫) which may be called experience, and the college students will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical (理論的) part -- the explanations of why things happen -- is frequently quite fantastic (神奇的) . But the demonstration (示范) and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he.
　　Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore (風(fēng)俗). All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in this wide, confused wilderness and how often scientific discoveries of what had existed in this area long age.
小題1: In the last paragraph the phrase "this wide, confused wilderness" refers to _____.
A．personal experience
B．wild weeds among good plants
C．the information from the parents
D．the vast store of traditional practices
小題2: Which of the following statements is supported by the passage?
A．The college students have trouble separating good plants from wild grass
B．Craftsman’s experience is usually unscientific
C．The contemptuous (傲慢的) college students will receive nothing from craftsmen
D．Traditional practices are as important as experience for the college students
小題3: The author advises the college students to ______ .
A．be contemptuous to the craftsman
B．be patient in helping the craftsman with scientific terms
C．learn the craftsman’s experience by judging it carefully
D．gain the craftsman’s experience without rejection
小題4: The main idea of this passage is about ________.

Where on Earth are you? Navigators (導(dǎo)航員) use lines of latitude and lines of longitude to locate places. Lines of latitude run east and west around Earth. On a map or globe, these lines appear as running sideways or horizontally. Lines of longitude run north and south around Earth. These lines go up and down or vertically on a map or globe. These lines create an imaginary graph paper on the Earth. They make it possible to find an absolute, or exact, location on Earth. They even allow us to give an absolute location to a place out in the middle of the ocean.
Lines of latitude tell us how far north or south of the Equator we are. Sailors have used primitive navigation tools, like astrolabes, since ancient times. The astrolabe uses the sun and stars to find an approximate location. Using such tools, they have been able to approximate their distance from the equator. Although their instruments may not have been the high quality we have now, they were incredibly accurate (精確) for their time.
Lines of longitude tell us how far east or west of the prime meridian (本初子午線) we are. Sailors constantly looked for new ways to increase their navigation skills. Still, it wasn’t until the 18th century that they were able to measure degrees of longitude. They would have been very envious of the technology available to us today.
When we use lines of latitude and longitude together, we can get a very precise location. If we want to identify the absolute location of a point, we look where the latitude and longitude lines cross nearest to that point. We use the coordinates (坐標(biāo)) for that point as its address. Many maps today include degrees of latitude and longitude.
小題1:______ make it possible for people to find an exact place on Earth.
A．LatitudesB．LongitudesC．NavigatorsD．Sailors
小題2:The second paragraph mainly talks about _______.
A．the function of latitudeB．the use of the equator
C．the invention of astrolabeD．the high quality instruments
小題3: Why do maps include degrees of latitude and longitude?
A．To help trade expeditions.B．To locate a precise place.
C．To cross the lines of the nearest point.D．To identify how far a place is.
小題4:The best title for this passage is ____________.
A．The map and the globeB．Latitude and longitude
C．The equator and the prime meridianD．Absolute coordinates

It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not.
In Kenya, researchers found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.
In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected(察覺)the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.
Clothing color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing.
The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.
小題1:According to the passage, which of the following statements is TRUE about Kamba and Maasai people?
A．Maasai people are a threat to elephants.
B．Kamba people raise elephants for farming.
C．Both Kamba and Maasai people are elephant hunters.
D．Both Kamba and Maasai people traditionally wear red clothing.
小題2: How did the elephants react to smell in the study?
A．They attacked a man with the smell of new clothing.
B．They needed time to relax when smelling something unfamiliar.
C．They became anxious when they smelled Kamba-scented(有…氣味的) clothing.
D．They were frightened and ran away when they smelled their enemies.
小題3: What is the main idea of this passage?
A．Elephants use sight and smell to detect danger.
B．Elephants attack people who wear red clothing.
C．Scientists are now able to control elephants’ emotions.
D．Some Kenyan tribes understand elephants’ emotions very well.
小題4:What can be inferred about the elephants’ behavior from this passage?
A．Elephants learn from their experience.
B．Elephants have sharper sense of smell than sight.
C．Elephants are more intelligent than other animals.
D．Elephants tend to attack rather than escape when in danger.

Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.
Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.
Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陳代謝的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.
Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.   
Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”
小題1:What contributes the most to one’s heart rates according to the first paragraph?
A．our bodyweightB．the consumption of energy
C．the rates of our breathingD．the amount of oxygen provided
小題2:Hormones are tested in the research because they can affect ______.
A．one’s bodyweightB．one’s blood pressure
C．one’s way of livingD．one’s metabolic rate
小題3:What was found about the 20 overweight men in the process of the research?
A．They controlled what to eat self-consciously.
B．They took in much fewer calories than usual.
C．They lost appetite because of lack of physical activity.
D．They were provided with a healthier diet than before.
小題4:Why does Damian Bailey agree with the idea of appetite loss at high altitudes?
A．He experimented with the new weight loss plan in the Andes.
B．He found no other reasons for his loss of weight in the Andes.
C．He researched the related subject in the Andes.
D．He lost much weight in the high altitude Andes.
小題5:In what manner does Lippl talk about the way of losing weight by spending holidays on mountains?
A．casualB．inaccurateC．uncertainD．confident

The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.
As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴蓮). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.
Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.
Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.
One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.
小題1:Before the experiment, volunteers ______.
A．a(chǎn)re gathered and take a training
B．cannot eat or drink for several hours
C．must wash their hands carefully
D．will be interviewed by Dr Finkelstein
小題2:If both men and women are asked to keep their hands in hot water while taking in some pleasant smells, ______.
A．women may stand the pain of the hot water longer
B．men may keep their hands in the hot water longer
C．they will probably take their hands out at the same time
D．we are not quite sure who will take their hands out earlier
小題3:From the passage we learn that _________.
A．the reason why women are sensitive to smells is clear
B．the experiment for the sense of smell has come to an end
C．unpleasant smells affect men’s senses more than women’s
D．scientists have not totally explained the result of the study
小題4:Now scientists believe that _______.
A．mothers recognize their children only by sight
B．men’s sense of smell developed a long time ago
C．strong smells have a great influence on people’s senses
D．smells are helpful for mothers to spot their children
小題5:The writer wrote the passage in order to ________.
A．supply some entertainment to us
B．show women’s sharper senses than men’s
C．inform the readers of some knowledge
D．call for volunteers for the experiment

Normal bicycle safety guides usually tell you to wear you helmet(頭盔) and to obey the law in order to avoid being hit on a bike. Is this advice really helpful?
Consider this for a moment: Wearing a helmet will absolutely do nothing to prevent you from getting hit by a car. Surely, a helmet might help you if you get hit, but you No.1 goal should be to avoid getting hit. Plenty of cyclists were killed by cars__________. However, if they had ridden without helmets, yet followed the guidelines listed below, they might still be alive today. So they saying that wearing a helmet is the first and last word in bike safety is, to some degree(在一定程度上), wrong.
The most common bike safety advice is “follow the law”. Ridiculously, most people are already aware that it’s stupid to race through a red light at a crossroads. As a result, it’s clear that the “follow the law” advice isn’t that helpful, either. In addition, following the law is not enough to keep you safe. Here’s an example: The law tells you to ride on the right, but if you ride too far to the right, someone started a parked car could open their door right in front of you and motorists pulling out of driveways and parking lots will be less visible. In that case you were following the law, but could still have been hit.
Then what should we remember in order to keep safe when riding a bike? I will tell you about it in the following paragraph.
小題1:What does the author say about wearing a helmet in the second paragraph?(within 8 words)
_________________________________________________________________________________________
小題2:Which sentence in the passage is the closest in meaning to the following one?
However, nearly everyone knows that riding through hared traffic light is dangerous.
_________________________________________________________________________________________
小題3:Please fill in the blank in the second paragraph with proper words or phrases to complete the sentence.(within 5 words)
_________________________________________________________________________________________
小題4: List the two regular bike safety guides.(within 8words)

Scholarship Application Tips in 2013 for college students
·Before you apply
1. Work hard to get good grades. Don’t sweat about one bad grade, but always strive(力求)to do your best.
2. Get involved, and stay involved, in extracurricular(課外的)activities. Sports, clubs, drama, bands and orchestras－these often count toward a student’s overall scholarship application evaluation. The same goes for paid (or unpaid) work experience.
3. Begin your scholarship research early－by your sophomore(大學(xué)二年級)or junior year of high school, if possible. Make special note of application deadlines, as they can vary from late summer to late spring.
4. Apply for as many scholarships as you are eligible(符合條件的)for－several smaller scholarships can add up to a lot of money.
·During the application process
1. Read the supplementary materials that come with scholarship application forms to better understand the program’s focus (community service, subject interest). Try to answer the questions with the focus area in mind.
2. Answer questions as they are asked. Don’t got off topic.
3. If there is a financial component to the application, make sure you get accurate and complete information from all appropriate sources to ensure your eligibility.
4. Take your time. Write down everything you can think of for each question, then set the application aside for a day so you can look everything over again before you send it off.
5. Don’t wait until the last minute to complete your application, especially if you are applying online. Computer systems can get clogged(阻塞的)with the large volume of applicants hoping to submit their qualifications during the last few days and hours before a deadline.
6. If a third party has to complete part of your application, such as providing a letter of recommendation, make sure you ask them early on and remind them as often as necessary to ensure they provide you with the necessary materials.
7. Last but not least, review your application with your parents to make sure you haven’t left out any important details.

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting.
Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed (抓傷). Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner.
We all like to cuddle (依偎) inside our bed, and cats do that thing, too. Much as little children like to wrap (用……纏繞) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace.
Usually the tip of the cat’s tail doesn’t draw our attention. But its particular position may also show the cat’s feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.
In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.
小題1:According to the text, in which way are cats different from dogs?
A．Cats draw more attention from humans than dogs.
B．Cats are friendlier to humans than dogs.
C．Cats have more feelings than dogs.
D．Cats show more feelings with tails than dogs.
小題2:When a cat waves its tail strongly from side to side, it probably feels    .
A．safeB．sleepyC．a(chǎn)nxiousD．hungry
小題3:A cat wraps its tail around its body when sleeping to      .
A．get its tail well relaxedB．get a sense of safety
C．show friendship to its ownerD．warn strangers to keep off
小題4:What does the fourth paragraph mainly tell us?
A．A cat can use its tail tip to show its feelings.
B．We should pay attention to the tip of a cat’s tail.
C．Why a cat holds the tip of its tail pointed downwards
D．A cat has many ways to express its feelings

Here is some news of the future.
March 20, 2035
There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well，it is too early to tell. But the sales so far are very good.
April 19, 2035
Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio of only 4.1% by year 1900, and 12.4% 30 years ago.
The number of people above 65 compared to those of what is considered working ages, between 15 and 64, is currently 33.7%. This is up from 18.5% since year 2005, which means that for every retired person there are now two workers, compared to four workers 30 years ago. The number of people above the age of 80 has grown to 23.8 million, making them 6.3% of the total population compared to 3.6% in 2005.
April 12, 2040
Although introduced in the market only five years ago, 10% of all hydrogen fuel now sold in the US is of the environmentally friendly Re-Hydro label, produced through eletrolysis(電解) based on a source of 100% renewable energy. Several producers have turned to producing Re-Hydro, mainly because of lower tax, which also keeps the price of Re-Hydro on the same level as regular hydrogen. Most analysts believe that Re-Hydro will be the dominating fuel in the future.
小題1:According to News 1 we know that the life extension drugs ____.
A．were first sold in the year 2025.
B．a(chǎn)re made to make people live forever.
C．should be taken when people are young.
D．have greatly increased the life expectancy rate at birth.
小題2:The sales of the life extension drugs so far clearly show that_____.
A．people have no faith in them
B．people want to give them a try
C．they work very well for seniors
D．they have no effect on people’s health
小題3:What can we learn from News 2?
A．Many Americans will find it hard to find a job.
B．It’s very hard for seniors to pass the age of 80.
C．The US population has been increasing rapidly since 2005.
D．The US population has been aging rapidly since 2005.
小題4:We can know from the passage that the fuel of the Re-Hydro label is ______.
A．expensiveB．cheapC．greenD．dangerous
小題5:What can we infer from News 3?
A．Re-Hydro will be widely used in the future.
B．The government discourages the production of Re-Hydro.
C．Producers are not interested in producing Re-Hydro.
D．Re-Hydro is more expensive than regular hydrogen.
