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
C. the coral under the sea D. The Great Barrier Reef.
2.What does the writer mean by saying "The Great Barrier Reef isn’t alone. "?
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.

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.
C. To advise Australians to solve global warming. D. To explain why the world gets warm

Carbon monoxide poisoning (一氧化碳中毒) causes death and injuries around the world. This gas is a problem in all parts of the world that experience cold weather. A few years ago, America’s Centers for Disease Control (C. D. C.) studied deaths linked (联系) with carbon monoxide poisoning. It found that the number of carbon monoxide deaths in the United States was greatest in January. The C.D.C. also found that carbon monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people are taken to hospital for treatment of health problems linked with the gas.
Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly (致命的). It steals the body’s ability to use oxygen.
Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues (血管). It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage (损害) to the body can begin very quickly from large amounts (数量) of carbon monoxide.
How quickly this can happen depend on how long a person is breathing the gas and how much gas he or she breathes in.
Carbon monoxide poisoning has warning signs(标志). But people have to be awake to realize them. Small amounts of the gas will cause a person’s head to hurt. He or she may begin to feel tired. Their stomachs may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.
People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache.
Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important.
1.The damage of carbon monoxide to the body has something to do with _____.
A. the amount a person breathes in
B. whether a person is healthy
C. how many signs a person finds
D. ages of people
2.One of the signs of carbon monoxide poisoning is _____.
A. burning eyes B. bad cough
C. serious headache D. high fever
3.Which of the following is TRUE according to the passage?
A. Carbon monoxide poisoning seldom happens in cold areas.
B. Twenty thousand Americans are killed by carbon monoxide each year.
C. Most people know whether there is carbon monoxide in the air.
D. Carbon monoxide stops the blood from carrying oxygen to body tissues.
4.What does the passage mainly talk about?
A. Warning signs that carbon monoxide poisoning has.
B. Reasons why carbon monoxide can cause person’s death.
C. The damage of carbon monoxide and how it works.
D. Influences of carbon monoxide on children and adults.
