It is reported that some of the main causes(原因) of death in the United States, such as heart disease(疾病) and cancer(癌症) can often be prevented by improving personal health habits. Good habits can help you to stay healthy, such as eating properly, staying active and not smoking.
Eating the right food and the right amount(数量) of food can help you live a longer and healthier life. Getting the nutrients(营养物) that you need and keeping your weight under control can also help. Try to balance the calories[卡(热量)] that you get from food with the calories you use through physical(科学的，自然的) activity.
You should eat different kinds of foods, especially low-fat(低脂的) foods, such as vegetables, fruit, fish and milk.
Weighing too much or too little can lead to health problems. After the age of 45, many people become overweight. You can control your weight by eating healthy foods and being active.
Physical exercise can help to prevent at least six diseases. It will also help you feel better and stay at a healthy weight. So you should spend time on physical exercise. If the weather is bad, try an exercise show on TV, watch on exercise tape(磁带) at home or walk around the shopping center.

A strong EI Nino（厄尔尼诺暖流）causes the temperature around the world to rise. “That’s how we will see the influences of climate (气候) change", says Michael Mann, a climate scientist at Penn State University.
The Great Barrier Reef (礁) is far beyond its name. Coral (珊瑚) of all shapes, sizes and colors covers more than 130,000 square meters off the coast of Australia, making it the world's largest reef system with many amazing kinds of life under the sea.
But today the Great Barrier Reef is dying. The waters around the reef become warmer. That warming then causes the bleaching(白化).The bleaching takes the color and the life out of the coral. Bleaching happens when the warm water and pollution drive away the living things that live on the coral and give it color. Within weeks, the reef could die, leaving behind a forest of lifeless, bone white coral. Scientists believe the bleaching may kill more than 15% of the world’s coral. The Great Barrier Reef isn't alone. This is the longest bleaching event ever recorded, " says David Kline, a scientist.
But a bigger worry may be what the bleaching suggests about future climate(气候)change. Climate change may be slow sometimes, but other times it takes great leaps forward, "says Steve Palumbi, an ocean scientist at Stanford University.
Local solutions like reducing fishing and cleaning up, pollution can help slow reef loss, but scientists say a global(8)problem requires a global solution. Nearly 200 countries agreed last year to work to keep global temperatures from rising more than 3. 6F by 2100, but that goal will be hard to reach.
1.The underlined word “It” in Paragraph 2 refers to (指代)_____________.
A. the country –Australia B. the coast of Australia

A. There are many other reefs beside the Great Barrier Reef.
B. There are kinds of living things on the Great Barrier Reef.
C. The Great Barrier Reef is becoming warmer and warmer.
D. Some other reefs have the same problem as the Great Barrier Reef.
3.After reading the article, you can learn that__________.
A. the climate is changing quickly within a short time
B. it's hard to see colorful coral when bleaching happens
C. the global warming is the only reason for the death of reefs
D. lots of countries found it easy to make the temperature low
4.What's the writer’s main purpose in writing the article?
A. To draw more attention to global warming B. To explain how bleaching happens.

Large population has caused many problems. For example, the traffic is very heavy in some big cities.
During the last ten years, big cities like Beijing and Harbin were full of cars and buses. Now the streets are completely crowded and it’s very difficult to drive a car along them. Drivers must stop at hundreds of traffic lights. What are our cities going to be like in the future? How can we solve the problem?
There are some good ideas to reduce the use of private(私人的) cars. In 1971, the officer in Rome began an interesting experiment: Passengers on the city buses didn’t pay for their tickets.
In Stockholm there was another experiment: People paid very little for a season ticket to travel on any bus, trolley bus(电车) and train all over the city.
In many cities now some streets are closed to vehicles(机动车) and pedestrians are safe there.
In London there is another experiment: Part of the streets is for buses only. So the buses can travel fast. There are no cars or taxis in front of them.
