At the age of 16, Julia Butterfly Hill quit school and worked at a restaurant. For many years, she was only interested in making money and material things. Then one day she had a serious car accident, which changed her life. Hill said: “I realized I wanted to find a more powerful purpose for being here on this planet.”

As soon as she recovered, Hill traveled to California. There she saw ancient redwood trees, which are the largest trees in the whole world. The wood from redwood trunks is very hard. So the Pacific Lumber Company cut down many of the huge redwoods to use for construction. There are not many forests of these trees left. Many environmental activists want to protect the remaining trees. The redwoods are very important to the environment.

In 1997 Hill learned a group called Earth First was working to protect a particular group of trees. They decided to send someone up into a redwood tree, hoping this would stop the company from cutting the trees down. Julia Butterfly Hill volunteered.

Hill lived in the tree for over two years without ever coming down. Her home was a 6-by-8-foot tree house, 180 feet up. It is always cold and wet in a redwood tree. There were even very serious winter storms while Hill was in the tree. The wind and cold almost knocked Hill out of the tree. But she did not fall — she survived.

Finally, after years of arguing, the company decided to protect Luna, the tree Hill lived in. They signed an agreement to never cut down this huge redwood tree or the trees around it. When Hill put her feet on the earth again, she began to cry. But from that moment on Hill hasn’t stopped working to protect the environment.

D. She is a self-centered woman

Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic(遗传的)structure with the simple worm.

But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome(染色体组).

To help them do this, they turned to the worm. The nematode(线虫类的)worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.

What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.

Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.

1.Sir John Sulston got a Nobel Prize for Medicine because he has .

A.found that human beings are similar to the worm

B.got the fact we share 40 per cent of our genetic structure with the simple worm

C.found the computer which controls each of the cells in the human body

D.proved that cell death is programmed

2.People might be seriously ill if the cells in their body .

A.grow without being instructed

B.die regularly

C.fail to follow people’s instructions

D.develop in the human body

3.The underlined word “they” (paragraph 5) refers to .

A.cell deaths B.diseases C.instructions D.cells

4.What is the subject discussed in the text?

A.The theory of programmed cell deaths.

B.A great scientist—Sir John Sulston.

C.The programmed human life.

D.Dangerous diseases.

Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.

Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.

Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen(花粉)kept in lake mud, Going back to the last ice age means drilling down into lake sediments(沉淀物), which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled(未取样). So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon forest reacts to climate change.

1.How do scientists study the past climate change?

A. By predicting the climate change in the future.

B. By drilling down deep into land sediments.

C. By analyzing fossilized pollen in lake mud.

D. By taking samples from rivers in the Amazon.

2.Why is it difficult to collect information about the past climate change?

A. Because scientists can't find proper equipment and machinery.

B. Because it is very difficult to obtain complete samples.

C. Because helicopters and aeroplanes have no place to land.

D. Because none of the cores provide any information.

3.Where is the passage most probably taken from?

A. A medical journal. B. A news report

C. A travel brochure. D. A science magazine.

4.The best title for the text may be .

A. Secrets of the Rainforest

B. Climates of the Amazon

C. The History of the Rainforest

D. Changes of the Rainforest

Dear Alcohol,

You’ve been around forever. I can remember all the pain you’ve caused for me.

Do you remember the night you almost took my father’s life? I do. He loves you. Sometimes I think he loves you more than he loves me. He’s addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn’t the only one hurt by you that night.

Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. “I’m so embarrassed,” they said as I held their hair back so that they could vomit (呕吐). “I’m sorry,” they said when I called taxis for them, walking them out and paying the driver in advance. “This won’t happen again,” they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.

Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn’t realize her brother was in the midst of it all. She never saw him again. And it’s all your fault.

I wish you’d walk out of my life forever. I don’t want anything to do with you. Look at all the pain you’ve caused. Sure, you’ve made people happy too from time to time. But the damage you’ve caused in the lives of millions is inexcusable. Stop luring(诱惑)in the people I love. Stop hurting me, please.

Sincerely,

Anonymous
