Paul Nicklen waited patiently on a sheet of ice in the Arctic.  He was there to take pictures for National Geographic. Finally, he saw something big and white. It was a polar bear, swimming towards him in the icy water.
Paul lay down-on the ice to get a better photo, but the polar bear jumped out of the water and tried to attack him! Luckily for Paul, the ice cracked or broke and the bear fell back into the water The polar bear wasn’t so lucky. It couldn’t get a meal and had to swim farther away to find food.
To understand the polar bear’s problem, you need to know two things about the Arctic. First, the Arctic is mostly ocean. Second , ice cover a lot of the Arctic Ocean. In winter, the ice form a thick, white sheet, but in summer, the ice becomes thinner and break into pieces. Sea ice is the key to survival for Arctic animals. However, because of global warming, Arctic temperatures are rising and polar ice is melting.
Polar bears need ice to hunt seals, their favourite meal. They stand on the ice wait for the seal to come up for air. As Arctic ice melts, polar bears have to swim farther to find ice floes, or large pieces of floating ice. Sometimes, bears have to swim more than 200 km to find an ice floe. Some bears cannot swim that far and sadly they drown.
On his last trip, Paul Nicklen saw three dead bodies of polar bears. Before global warming threatened Arctic ice, a dead bear was a rare sight, Paul is sad to see the dead bodies, wildlife experts thinks global warming will have a terrible effect on polar bears. In the future, polar ice will continue to shrink and endanger the bear. Some scientists believe 65 percent of the world’s polar bears will disappear by 2050. in other word, polar bears are in great danger.

Most kids hate doing housework. However, not all hope is lost. There are some things that you can do to get your kids to help you clean your house. If you are struggling with the chores (家務)and need your kids to help you, take a look at some of the creative ways in this article.
If you are dealing with older kids, you may want to try the allowance deal. You can give your kids a list of chores that need to be done each week. If they complete these chores, you can give them some money. You can also break the list down and tell them they will get so much for each chore that is finished. Older kids , who like to do things on weekends or buy things like video games, will work hard to complete their chores and earn their money. This is also teaching them responsibility. This is teaching them that they must work for what they want.
If you are dealing with younger kids, you may want to go with the rewards chart(獎勵圖表). This is where you design a chart and list their chores on the chart. For each chore they complete, you can put a red flower beside it. For the rewards, you canalso do a number of things ,such as going to the park, going out to eat, buying a DVD or something similar. The rewards would be up to you because you know what your kids like.
For real small kids, you can turn it into a game. When kids were much younger, you can teach them to dance around and sing as you cleaned. The kids loved it and would do a wonderful job at picking up their toys. So, consider turning cleaning into a game for the real small kids.

We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.

Height is just one of the features your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too. But if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find them out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential (潛力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
It’s natural that you’re wondering how fast you should grow. There’s no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty .
Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you’re at now. How have you been growing up to this height?What other changes may your body be going through?
Don’t be amazed if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later — between 7 and 13 for girls and 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year after your body starts to show the first changes of puberty.
小題1:If you want to know how tall you should grow, _______.
A.you should have enough exercise
B.you can ask doctors for help
C.you should take some special medicine
D.you can record your growth during puberty
小題2:The Chinese for the word “ puberty ” is _______.
A.童年時期B.嬰幼兒時期
C.習慣養成期D.生長發育期
小題3:This passage is mainly about ______.
A.how the genes work in your body
B.how your parents’ height influence you
C.how you look like your parents
D.how you grow to a certain height
小題4:After reading this passage, we can explain ______.
A.how good it is to be a doctor
B.how much sleep time we need
C.why genes can’t decide everything
D.what healthy diet is
小題5:Which is NOT mentioned in the passage?
A.Your height most probably depends on how tall your parents are.
B.Girls’ age for starting puberty is usually earlier than that for boys’.
C.The features showing the first changes of puberty between boys and girls are different.
D.You may be amazed sometimes when you grow too fast.

  It was New Year’s Night. An aged man was standing at a window. He raised his mournful eyes towards the deep blue sky, where the stars were floating like white lilies on the surface of a clear calm lake.
He had already passed sixty and brought from his journey nothing but errors and regrets. Now his health was poor, his mind vacant and his heart sorrowful.
The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads- one leading to a peaceful, sunny place, covered with flowers, fruits and filled with soft, sweet songs; the other leading to a deep, dark cave, which was endless, where poison flowed instead of water and devils and poisonous snake hissed ( 發嘶嘶聲) and crawled (爬, 爬行).
He saw the lights flowing away in the darkness. These were the days of his wasted life; he saw a star fall from the sky and disappeared, and this was the symbol of himself. His regret like a sharp arrow struck deeply into his heart. Then he remembered his friends in his childhood. But they had made their way to success and were now honoured and happy on this night.
The high church clock struck and the sound made him remember his parents’ early love for him. They had taught him and prayed for his good. But he chose the wrong way. With shame and grief he dared no longer look towards that heaven. His darkened eyes were full of tears, and with a despairing effort, he burst out a cry: “Come back, my early days!”
His youth did return, for all this was only a dream which he had on New Year Night. He was still young though his faults were real; he had not yet entered the deep, dark cave, and he was still free to walk on the road which leads to the peaceful and sunny land.
Those who still wander on the entrance of life, hesitating to choose the bright road, remember that when years are passed and your feet stumble (絆腳) on the dark mountains, you will cry bitterly, but in vain(徒勞): “ Oh youth, return! Oh give me back my early days!”
小題1: Why does the author set his story on New Year’s Night?
A.He wants to tell people it’s time to recall the past
B.He suggests the aged man will have a bright future
C.He attempts to stress(強調)the man’s sad feeling
D.He expects people to share the man’s sad feeling
小題2: The aged man in the passage on New Year’s Night can be described as ____.
A.sorrowful, fearful and regretful
B.hopeful, sorrowful and peaceful
C.regretful, painful and disappointed
D.disappointed, regretful and hopeful
小題3: The author writes the passage mainly to ____.
A.encourage young people to take the right road
B.help the old man to pick up his confidence
C.describe the old man’s unsuccessful experience
D.show his sympathy for the old man

You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely connected to the big problem of global-warming (全球變暖).
WAY 1: Bring your own cup to Starbucks. You’ll get a 10-cent discount, and it’s one less paper cup to end up in a dustbin. The store won’t create more waste when they throw away a cup.
WAY 2: Turn off your computer. When in standby mode, your PC is still using energy. Turning off a monitor (顯示器) for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds.
WAY 3: Reuse plastic bags. Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. The amount of oil it would take to make just 14 plastic bags would run your car for one mile.
WAY 4: Use recycled paper in the bathroom. Most of the toilet paper we use is made from trees found in forests. If every family replaced(替換)one roll of toilet paper with a recycled one, 424,000 trees would still be standing.
WAY 5: Plant a tree. Adding green to your garden is beautiful and earth-pleasing. Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year.
小題1:How many ways are mentioned(提及) in the passage?
A.Two. B.Three.
C.Four.D.Five.
小題2:What will happen if our PC is turned off when it isn’t in use?
A.It will help to save a large amount of money.
B.It will help to reduce a great deal of CO?.
C.It will save the amount of oil that runs your car for a mile.
D.It will be like planting 1.7 million acres of new trees.
小題3:Which ways suggest recycling or reusing of things?
A.Ways 3 & 4.B.Ways 2 & 3.  
C.Ways 3 & 5.D.Ways 2 & 4.
小題4:How do these ways do good to our environment?
A.They all help reduce the use of energy like electricity. 
B.They all cut down the number of the use of paper.
C.They all produce less greenhouse gases as a result.
D.They all help protect our trees and forests.
小題5:What is the best title for the passage?
A.Ways toSave MoneyB.Waysto Be Earth-Friendly
C.Ways to End Global-WarmingD.Waysto Limit Carbon Dioxide

Over 30% of the natural world has been seriously destroyed by humans (人類) over the last 30 years. This is because the number of people living on Earth is nearly six billion (十億). All of these people need food, space and energy. As a result, lots of Earth’s natural resources will be used up. When we destroy our earth to get natural resources such as wood or oil, animals often lose their living space. They cannot have enough food, and they will get hurt or die.
The World Wide Fund for Nature (WWF) is an international charity. It tries to prevent humans from destroying more of nature than is necessary. For example, in China WWF is working with the local government to reconnect (重新連接) some small lakes in Anhui Province to the Yangtze River and to create(創造) more protected areas so that China’s natural beauty will not be lost in the future. WWF works in more than 50 countries, saving rainforests and stopping hunters from killing rare animals and protecting traditional ways of life in areas where they are in danger of being lost. WWF’s main goal is to encourage development that does not harm the environment and the animals that live in it. Even though the charity is known all over the world, and a lot of people support the goals of WWF, not so many donate money often. This makes it difficult for the charity to do all the things it wants to do.
小題1:Why has over 30% of the natural world been destroyed?
A.Because hunters are killing rare animals.
B.Because not enough people help WWF.
C.Because WWF does not have enough money.
D.Because there are so many people living on Earth.
小題2: How has WWF helped in China?
A.They have protected traditional ways of life.
B.They have helped to protect China’s natural beauty.
C.They have saved many rainforests in Anhui Province.
D.They have built some bridges over the Yangtze River.
小題3:What is WWF’s main goal?
A.To save rainforests.
B.To stop hunters killing rare animals.
C.To get more people to donate money.
D.To protect the environment while developing.
小題4:Why is it difficult for WWF to do all the things they want to?
A.Because too many people do not know WWF.
B.Because WWF doesn’t have enough money from donations
C.Because there are too many problems for them to solve.
D.Because WWF doesn’t encourage development.

Is it difficult for you to get up in the morning? Hiroyuki’s bed will solve your problem! Here is how it works.
  The bed is connected to an alarm clock(鬧鐘). First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music. The tape recorder in Hiroyuki’s bed plays a recording of his girlfriend. She whispered in a soft voice, “Wake up, darling, please.” After minutes later, Hiroyuki hears a recording of his boss. His boss shouts, “Wake up at once, or you’ll be late!”
If you don’t get up after the second recording, a mechanical(機械的) “foot” in the bed will kick you in the head. The bed waits a few more minutes. What! You’re still in bed! Slowly the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally you slide(滑落) off the bed and onto the floor. You are out of bed awake!
  Hiroyuki’s bed is not in stores. There is only one bed — the bed Hiroyuki made for a contest(比賽). Maybe someday a company will make Hiroyuki’s bed and sell it in stores. Maybe people will buy millions of beds. Then Hiroyuki will be rich. If the bed makes Hiroyuki rich, he won’t need to work, and he won’t need to get up early!

C
Why are you study habits different from those of your friends? Why do you seem to learn faster in some classes while more slowly in others? One reason you may not know is that people have different types. Scientists say there are three different learning types: Visual(視覺型),Auditory(聽覺型),and Kinesthetic (動覺型)。
Visual learners learn best by seeing. If you seem to easily remember information from pictures, graphs(圖表),and videos, you are probably a visual learner. You’re not good at copying down what the teacher says in class. Never mind. You can draw graphs or pictures instead, if you find that works better for you.
Auditory learners learn best by hearing. If you seem to easily remember things by hearing them, then you are probably an auditory learner. You must listen carefully while the teacher is speaking because it’s the easiest way for you to learn . Sometimes you may find that taking notes tops you from listening carefully. After class, you can write down what you remember or borrow your friend’s notes to copy.
Kinesthetic learners learn best by doing. If you seem to learn best by working with your hands, you are probably a kinesthetic learner. Taking notes by writing can make you pay close attention to information as you receive it. Of course, you can learn best by making full use of labs or other class activities.
Hope you learn better by knowing what your personal learning type is.
小題1:There are____________ different learning types according to the passage.
A.twoB.threeC.fourD.five
小題2:Jude can remember the words of a song quickly by listening to it once or twice. She might be a /an ____________ according to the passage.
A.auditory learnerB.visual learner
C.strange leanerD.usual learner
小題3:Kinesthetic learners learn best by  ____________
A.Remembering information from videosB.listening teachers in class
C.drawing graphs or picturesD.doing things with their hands
小題4:The best title of this passage may be “____________”
A.Study HabitsB.Ways to study
