In recent years, the Earth has been getting warmer. Average temperatures have risen. Possibly this is natural, but probably we are causing it. Modern people use a lot of electricity and drive a lot of cars. This puts carbon dioxide（二氧化碳）into the air and helps to make the planet warmer. When we hear the news, we may smile. No one likes long, cold winters, but, unluckily, there are many bad points about a warmer Earth.

First, the ice at the Poles melts and becomes water. The result is that the sea level becomes higher. Low islands will vanish（消失）. Cities on the coast will be in danger from the sea. Will Tokyo, Bangkok, Hong Kong and Shanghai become like parts of Holland — lower than the sea? Possibly we will have to build walls to keep the water out. Typhoons will become even more dangerous and frightening.

Sadly, the second point is that storms will become bigger. Super-typhoons will be born in the Pacific and do great damage to East Asia. The same will happen to the Eastern United States.

As the weather changes, some places that now have rain will become dry. The farmers will not be able to grow plants. Maybe some dry places will become wet — we don’t know, but we will soon find out, and the change will cause many problems. There might be wars because of it.

1.The sea level becomes _________ if the ice at the Poles melts and becomes water.

A.lower B.smaller C.higher D.bigger

2.Super-typhoons born in the Pacific will damage _________.

3.What will happen to low islands when the Earth gets warmer and warner?

A.They will melt and become water. B.They will disappear.

C.They will become higher. D.They will keep the water out.

4.Which of the following sentences is NOT TRUE?

A.Shanghai will possibly build walls to prevent the water.

B.Some farmers will not be able to grow plants because of the dry weather.

C.Only electricity puts carbon dioxide into the air.

D.The warmer the Earth is getting, the higher the average temperature will be.

5.In the last sentence, “it” refers to _________.

A.the change of the weather B.the strong typhoon

C.the ice at the Poles D.the average temperature

6.Which is the best title of this passage?

A.The Earth is Getting Warmer. B.How to Protect the Earth.

1Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).

The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.

Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.

Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

DNA is the whole “map” of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They’re written in the DNA with a special language.

In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell(细胞) to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive(吸引人的), or stop sick people getting jobs.

1.What did the two scientists find in 1961? They found ______.

A. all the words in the DNA map

B. small things called “genes” in our body

C. the first “word” they could understand in that language

D. those small parts are written in the DNA with a special language

2.Which one is not true according to the article?

A. We look like our parents because of “genes” in our body.

B. We have understood what all the words in the DNA map do.

C. DNA is the whole “map” of the human body.

D. DNA tells the cell to build its parts.

3.What do people think about this research about DNA?

A. It can be only bad.　　 B. It can be only good.

C. It can be good but won’t work.　　 D. It can be good and bad.

4.How can we help sick people if we understand more “words” in the DNA map?

A. Make better medicine.　　 B. Make them get jobs.

C. Make maps for them.　　 D. Make them attractive.
