Three key facts about rising sea levels need to be pointed out to the world's politicians and planners: sea-level rise is now unavoidable, it will happen faster than most of us thought, and it will go on for a very long time.
Even greenhouse gas emissions (排放) stopped tomorrow, the oceans will continue to become larger as they get warm. The climate scientists estimate that sea-level rise may be in the range of 1 to 2 meters by 2100, with a small risk of an even greater rise.
For many islands and low-lying regions, even small rises will cause disasters. But for most countries, the problem is what has been built on that land: New York, Sydney and Tokyo, to mention just a few cities. Unless something can be done, great areas of urban network will disappear under the waves. It will take a great engineering effort to protect these cities---an effort that may be beyond economies that have been brought to their knees.
None of this means we should fear, and stop trying to forbid emissions. But together with these efforts, we need to start acting now and we must stop building in danger zones.
Billions of dollars are being spent on constructing homes, offices and roads in vulnerable coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is merely 4 meters above sea level on average, and they are sinking under the weight of the buildings. Therefore, planning for new coastal developments is to go against reality. If we want to build a lasting heritage for our children, we should do so on the plentiful land that is in no danger from the sea. It is one of the effective ways to slow down climate change, and we should be acting on it now.Which of the following about sea-level rise is true?
| A．It will be brought under control by 2100. |
| B．It will cause few problems to many islands. |
| C．It may become worse than we expected. |
| D．It may be caused by fast urban development. |
New York, Sydney, and Tokyo are mentioned in this passage to show _______.
| A．modern cities are usually built along the coastline |
| B．the coastline is very important for modern countries |
| C．climate changes have endangered many big cities on land |
| D．climate changes have been completely out of control |
What does the underlined word “vulnerable” in the last paragraph means?
| A．difficult to build |
| B．easy to damage |
| C．likely to be protected |
| D．impossible to make sure of |
What’s the main purpose of this passage?
| A．To explain why sea-level is rising. |
| B．To tell us the danger of sea-level rise. |
| C．To warn us of greenhouse gas emission. |
| D．To discuss the disadvantage of building coastal cities. |
A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit. There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests. Rainforests can help to adjust the climate because they________.
| A．reflect more heat into the atmosphere |
| B．bring about high rainfall throughout the world |
| C．rarely cause the temperature to drop lower than 16℃ |
| D．absorb the heat from the sun, reducing the effect of heat from the sun on the earth |
What does the word “this” underlined in the third paragraph refer to?
| A．We will lose much more than we can gain. |
| B．Humans have begun destroying rainforests. |
| C．People have a strong desire for resources. |
| D．Much carbon dioxide comes from burning rainforests. |
It can be inferred from the text that________.
| A．we can get enough resources without rainforests |
| B．there is great medicine potential in rainforests |
| C．we will grow fewer kinds of crops in the gained land |
| D．the level of annual rainfall affects wind patterns |
. What might be the best title for the text?
| A．How to Save Rainforests? |
| B．How to Protect Nature? |
| C．Rainforests and the Environment. |
| D．Rainforests and Medical Development. |
Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.Why do people kill animals?
| A．They kill animals for something they need. |
| B．They kill animals to raise some money. |
| C．Animals destroy their natural resources. |
| D．Animals create many problems. |
Animals are important to us mainly because ______.
| A．they give us a source of food |
| B．they are beautiful and lovely |
| C．they keep the balance of nature |
| D．they give us a lot of pleasure |
Which of the following is NOT true?
| A．People care much about animals because they need them. |
| B．Once a certain kind of animal is gone forever, there will never be any more. |
| C．Killing all rats and mice may cause some new problems. |
| D．People must not kill any animal or plant. |
“If you want to see a thing well，reach out and touch it！”
That may seem a strange thing to say.But touching things can help you to see them better.
Your eyes can tell you that glass ball is round.But by holding it in your hands，you can feel how smooth and cool the ball is.You can feel how heavy the glass is.
When you feel all these about the ball，you really see it.
With your skin，you can feel better.For example，your fingers can tell the difference between two coins in your pocket.You can feel a little drop of water on the back of your hand，too.
You can even feel sounds against your skin.Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch！” means.They hear it often.Yet most of us keep on touching things as we grow up.In shops，we touch things we might buy，such as food，clothes and so on.To see something well，we have to touch it.

In recent years，American students have fallen behind in many subjects like math，science and reading. In 2005，the U.S. was number nine among the developed countries in the number of students graduating from high school.
American education officials are searching for new ways to help students learn again. One tool that is getting some attention is the use of video games.
Sixteenyearold John Diaz says he loves playing video games but doesn't like traditional schoolwork. During his summer vacation，Diaz is continuing his studies at home. That is because his courses are available on his home computer.
Florida Virtual School's head master，Julie Young，says the school teaches students with the technology they most enjoy using in and out of school.“We have so many students who feel free in our school，” Young said, “They lose interest when they go to school. And we're very hopeful that Conspiracy Code will attract the learners to really get into the detail of learning.”
Conspiracy Code is a video game that teaches U.S. history. Students guide two heroes in a quest to stop a conspiracy to change the past. Along the way，students learn about events such as the Civil War，and report back to their teacher who is a spy ．

When my son was a teenager he already knew he wanted things. He wanted nice things and he wanted to get them by himself.He never depended upon us to provide for him.He gladly accepted the room and other different necessities we gave him，but when it came to the luxuries (奢侈品)，or the extra things of life，he knew he would have to make his own way.
At the age of 13，he started talking to me about working.His sister had worked at a local amusement park for several years as her first job so he gave that some thought. He had us drive him to the park and he went in and applied. Within two days he was called back to go to work. His sister had been a model employee and the park didn't even ask what he was able to do.
He worked at least 20 hours a week at the local amusement park. With his first week check he came home with a big smile. He had made something like $60 for his four days of afterschool efforts，and he wanted to thank us for our contribution to his wealth. He needed transportation both to and from work so we would take him there and back；no matter when the park closed，we would be there.
With his very first check，he insisted on treating me and his dad. He took us and his sister to an expensive restaurant. We had a wonderful time there and we spent his entire check. He didn't care；he knew he had to take care of those who had made it possible for him to have the check in the first place. He had always been a generous boy，perhaps too generous sometimes，but very loving.In his teens，the boy________.
