Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no medicine, either.
Life today brings new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly.
Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
Rules are not enough. We should do our best to fight against pollution.

Like schools in China, American schools begin in September after a long summer vacation. There are two terms in a school year. The first term is from September to January and the second is from February to June. Usually American children begin to go to school when they are five years old. Most students are seventeen or eighteen years old when they finish high school.
But unlike middle school students in China, high school students in America take only four or five subjects each term. They usually go to the same classes every day and have homework for every class. After class they do all kinds of interesting things.
After high school, many students go to college. They may go to a small or a large one. They usually have to pay a lot for their higher education. So lots of students work after school to make money for their studies.

No Car Day was first started by 34 cities in France on September 22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.
The first No Car Day in China was in Chengdu in 2001. Other cities including Taipei, Shanghai and Wuhan, also support the day.
In Beijing, more and more people are taking part in the activity. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5th (World Environment Day). The slogan(口號) for the day is, “ If we drive for one less day, we can have one more nice day.”
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive,” said Wu Zhonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of 2007, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period last year. Much of the dust comes from the desert, but cars cause most of the air pollution. We must do more for No Car Day.
小題1:No Car Day was started _______.
A.to save moneyB.to control the weather

閱讀短文,根據其內容回答問題。
Phys ed (physical education) is making a comeback, but with a difference. The new way is to teach skills that are useful beyond gym class, like lifting weights, balancing their diets and building physical endurance(耐力).
Considering that 15% of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards(教育委員會)often “cut P.E. completely or decrease(減少)its teachers or the days it is offered,” says Alicia Moag-Stahlberg, the director of Action for Health Kids. The difference in phys ed programs is its short of a national standard.
The wisdom of the new idea has some scientific support. Researchers at the University of Wisconsin have showed how successful the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers have also found that teaching group sports like football results in less overall(全體的)movement, partly because the students who are unwilling to do may sit on the bench.
Another problem with simply teaching group sports in gym class is that only a small part of students continue playing them after finishing their high school. The new method teaches skills that translate to adulthood, which means kids are given skills and experiences so they can lead a physically active life in their future.
小題1:Is the new Phys ed program different from the one before?
小題2:What does the new P.E. program teach the students?
小題3:According to the passage, what do some school boards do with P.E?
小題4:What are the problems with simply teaching group sports?
小題5:What’s the passage mainly about?

Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸氣) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day’s work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful.

Reading is very important. World Book Day falls on April 23 every year. It encourages people, especially teenagers, to discover the pleasure of reading. It is also the day to honor (尊敬) great writers.
