overweight, and some of this is because of their bad eating habits. Most teenagers love food with a lot of
fat, oil, salt and sugar. People often call this kind of food "junk food".
But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don"t have
breakfast before they go to school. During the day, some don"t have a proper meal for lunch. In a recent
survey at one school, scientists found that over two-thirds of the students didn"t follow a healthy diet. They
didn"t like vegetables, and many of them didn"t like to eat fruits. They preferred to eat food with a lot of salt,
sugar or fat.
Parents today also worry about their children"s diet. Some doctors give the following advice:
Teenagers shouldn"t eat too much junk food.
Teenagers shouldn"t eat food with too much salt. Salt can cause high blood pressure in the future.
Teenagers should eat food with less fat, oil and sugar.
Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins and
have little fat.
Teenagers need to drink more milk. Milk will help their bones grow.

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 (二氧化碳) 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 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 (空调), 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. It"s time for all of us to do
something to save the earth.

or salt water. Man can only drink or use the other 3%of the fresh water (淡水) which comes from rivers,
lakes and underground. On the other hand, because the number of people in the world is becoming larger and
larger, more and more fresh water is needed. So water shortage becomes a big problem.
How can we work out this problem? Scientists have found some ways to turn salt water into fresh water.
One important way is to boil (使达到沸点) sea water with high heat until vapor (蒸汽) rises, leaving the salt. In
this way, a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water. Other ways are tried, for example, digging (挖) deep wells
(深井), keeping rain water and preventing rivers from being polluted.
Which way is the best? To get the most fresh water for the least money is the best.
B. Rivers and lakes.
C. Underground.
D. Both B and C.
B. can be used in many ways
C. can be found in many factories

D. being less
B. How to use fresh water in our daily life.
C. All people in the world should save water.
D. Different ways of making water in different places.
B. Water shortage is the only problem in our world.
C. Scientists don"t want to spend money solving the water problem.
D. Scientists have been working hard and have made much progress in solving water problem.
others often forget to turnoff the lights when they leave the classroom.
They say they can afford these things. But I don"t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources (资源), we are short of
(缺乏) others, for example, fresh water (淡水). It is reported that we will have no coal (煤) or oil to use
in 100 years. So if we go on wasting our resources, what can we use in the future and where can we
move? Think about it. I think we should say no to the students who waste things every day. Everybody
should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off
the water taps (水龙头) when we finish washing, turn off the lights when we leave the classroom, try
not to order more food than we need, and so on. Little by little, everything will be changed. Waste can
be stopped one day if we do our best.

C. China is rich in fresh water.
D. Students never waste things.

laughter seriously and finding it is really good. One minute of laughter is the same as forty-five minutes of
relaxation(放松). Many doctors around the world believe that laughter helps us get better when we are sick.
Of course, there are many kinds of laughter. We may change the way we laugh in different situations
(情形). But we all have a laugh that is special to us. How do you usually laugh?

bags. If you don"t want to pay money to buy them, you"ll have to bring your own shopping bag. What kind
of bags will be the best to bring? Students in Kunming Xinying Middle School have some good ideas. Fifty-
four students of the school held an activity. They made their own environmentally-friendly (对环境无害的)
shopping bags in it. Most students use ole clothes to make their bags. They painted pictures like the Olympic
rings on them. But Wang Shuncheng, a Junior-Two boy, chose a different material (材料). He made his bag
with old newspaper. Is a newspaper bag strong enough to hold shopping? "No problem. I put six bottles of
water in the bag." He said, "It"s strong enough!"
Chen Lisi, a girl, had a more traditional way to make her bag-she wove (编织) a bamboo bag. It was not
an easy job. With her grandfather"s help, Chen spent a whole afternoon making it. She also wove cool (毛线)
flowers on the bag.
Making bags was not all the students did. They had another job: to persuade their parents and relatives
(亲戚) to use environmentally-friendly shopping bags instead of plastic ones. The school will show the bags
so that shops and stores can get some ideas from the students" work.
B. we cannot buy plastic bags from most supermarkets
