Many people think that water will never be used up（用尽）because there are many rivers and lakes. And the rain can make us get enough fresh water. Also, we can dig wells（井）to find fresh water under the ground. In fact, it is wrong and dangerous to think so. In some areas, people fight（争斗）for fresh water. There is little rain there all year round. Let’s look around us. Some factories pour（倒）dirty water into rivers. And some people drop litter into rivers. We see polluted water here and there. We must do something to help people understand about preventing water from being polluted. It’s never too late if we take action right now.

Wind is the great maker of waves. There are exceptions (例外), such as the tidal (潮汐的) waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea .
Now let’s learn some physical (自然地理学的) things about it. A wave has height, from low point to high point . It has length (长度)--the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon (依靠)the wind, upon the depth (深度) of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position (原先的位置). And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" × frequency (频率).
Here, wavelength is the distance between two high points , frequency means the number of cycles per second
小题1:What causes waves?
A．Earthquakes and nothing else. B．Only wind.

D．The length of a wave means the distance from the top of a wave to the bottom.
小题3:The speed of Wave 1 is 100 cm/s, frequency 10. The frequency of Wave 2 is 300, while its speed is twice that of Wave 1. Which of the following is right?
A．The wavelengths of the two are equal.
B．The wavelength of Wave 1 is 10 times longer than that of Wave 2.
C．The wavelength of Wave 2 is longer than that of Wave 1.
D．The wavelength of Wave 1 is longer than that of Wave 2.

Did you see snow in your hometown last winter? Did you feel it was warmer than before?
"There have been 21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 °C , the temperature in North China has climbed 1.4 °C in only 50 years.
China needs to take quick action to cut carbon dioxide emission (排放)
because it's the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20% and pollution emission by 10% in the 11th Five-Year Plan.
Can you slow down global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.
Here are some pieces of advice to help you save the earth..
Wear used clothes. Wearing your brother's, sister's or dad's old T-shirt means you save the energy.                                                                       
Change your light bulbs (灯泡). Use energy-saving light bulbs. And don't forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!
Ride the bus. Taking a bus saves a lot of oil every year.
Say no to plastic bags. The next time your parents go to the market, ask them to use baskets
Open a window. Don't use the air conditioner, and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.
Make small changes in your daily life. Don't use paper cups, bags and boxes.

Some teenagers think that newspapers are boring and only for adults. But that's not true. There are many interesting stories in the paper. You just need to make clear what you are looking at. “I spend about half an hour reading newspapers every day,” said 15-year-old Gao Ming from Beijing. “I'm interested in things happening at school.” School news is just one kind of news story in newspapers. There's also world news: from international problems to pop stars.
Read the newspaper carefully, we'll find different types of articles on the pages:
News stories — these stories are about events. Reporters try to show all points of a story to help readers understand what happened. Reporters try to speak to as many people as possible. They also use pictures and numbers to show the readers that the stories are true. The newspaper Teenagers has lots of news stories on the news page and front page. When we read them, we learn more about the facts, not the writers’ ideas.
Opinion writing — opinion writing is usually about something happening right now. But it isn't just facts. Here writers add their own opinions to the news. Writers pick only the facts that help back up their ideas. They make readers believe that they are telling the truth. This is usually the kind of story that gets people thinking. Go to “Speak Out” on Page Two for an example of opinion writing in Teenagers.
Advertisement — Don’t get happy too early when you read them. Those sweet words and lovely pictures are just ways to get us interested in their products! People have to pay to put advertisements in newspapers!
小题1:The underlined sentence means that the readers "_______".
A．should understand interesting news stories
B．ought to know which kind of things to read
C．need to look at the school news first
D．must know the contents of all the news
小题2:This passage mainly discusses how_______.
A．reporters write different kinds of news
B．teenagers get interested in newspapers

When we talk about the climate（气候）of the UK, you may think of f   1   London and rainy weather. Actually, after many years, London is not as foggy as it used to be because the government is trying their best to solve the p  2   of air pollution, which is the major(主要的) r   3  of the thick fog in London.
However, it is t  4   that it often rains in the UK and the weather always changes quickly. Maybe you wish to play tennis with your friend after work when you see the beautiful sunshine in the morning, but suddenly the wind comes and it r  5  when you go to work.
The difference in temperature b  6  winter and s   7   is not so great in the UK as in China. The average（平均的）t  8   for winter is about 4.5℃, and for summer about 15.5℃.
And the best time to visit the country is in summer. It is often s   9  and you can enjoy outdoor sports and have a picnic h 10   in such weather.
Now more and more people in the world are getting fatter. This troubles them a lot. Experts(专家) say that it has a lot to do with  our eating habits.
Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite(食欲).
It's important for us to eat our meal in the same period  each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the truth by giving him some dry bread. If the man could not swallow(吞) the bread, it meant that he wasn't telling the truth. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.

Dolphins are not fish. They are mammals (哺乳动物).They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain(大脑)is as big as men's and they live a long life at least 20 or 30 years.
Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth.
It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin.
Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.
小题1:The word "jaw" means_________in Chinese.
A．下颚B．嘴巴C．嘴唇D．鼻子
小题2:How do dolphins find their way?
A．They use their noses to smell the way.
B．They use their ears to hear the sounds.
C．They use their eyes to see the way.
D．They use sounds to find the way.
小题3:Who was Jack?
A．The writer.B．A dolphin.C．A seaman.D．The passenger.
小题4:The dolphin guided the ships for about________.
A．32 yearsB．9 yearsC．41 yearsD．23 years
小题5:According to the passage, which of the following is NOT right?
A．Dolphins are not fish.
B．Dolphins don't live in groups.
C．Dolphins are kind and friendly to people.
D．Dolphins can live a long life.
Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.
One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.
小题1:GM foods ________.
A．are a quick way to produce food
B．grow in the wild
C．are safe
D．are grown only in rich countries
小题2:Why do some people not like GM foods?
A．They are not useful.
B．They are not helpful.
C．They are not natural.
D．They are not cheap.
小题3:From the reading we know that ________.
A．GM foods will disappear one day in the future
B．GM foods will not disappear in the future
C．people will not be interested in GM foods
D．people will have to stop using GM foods
