One reaction to all the concern about tropical deforestation(毁林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"

The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.

Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.

Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.

Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.

Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.

Can tropical deforestation affect our everyday lives? Now, you should have got the answer.

1.The underlined word "synthetics" probably means_________.

A. natural rubber B. tropical materials

C. man-made material D. commercial rubber

2.According to the passage, which of the following is NOT true?

A. The forests are losing their function in turning carbon dioxide into oxygen.

B. Many of our daily uses are related to the tropical forests.

C. Tropical plants can be used to make industrial products.

D. High carbon dioxide levels will make the earth warmer.

3.The author's attitude towards the tropical deforestation is _________ .

A. puzzling B. cold

C. supporting D. opposed

4.Which of the following might be the best title for the passage?

A. Tropical Forests B. The Value of Tropical Forests

C. Tropical Forests and Our Life D. The Greenhouse Effects

Five boys are suspected of starting a fire that destroyed their school on the eve of the new term. Police said yesterday that five boys — one aged 11, two 12-year-olds, one aged 13 and one 15 — arrested on suspicion of starting the fire had been released until later this month. Parents said the five pupils all attended St Mary’s.

Pupils witnessed their schoolwork being destroyed in the fire at Leyland St Mary’s Catholic Technology College in Lancashire. The 1950s science block was reduced to the ground in Sunday’s fire, which created clouds of smoke visible for miles. It is reported that the library and sports hall were also destroyed beyond repair. Strong winds and a shortage of water prevented 125 firemen trying to bring it under control. Firefighters were expected to remain at the scene until late this afternoon. Staffs were due to attend the school yesterday for an inset(培训)day, and pupils pupils were to return for lessons after the holidays today.

St Mary’s head teacher Kathy McNicholas fought back the tears as she watched her school go up in flames last night. She said, “This is so upsetting to watch. It’s heartbreaking. It’s very distressing for the staff and the children. Everyone had been looking forward to coming back for the new school year.” Finding somewhere around 730 children won’t be easy. A few of the staff have turned up to see if there is anything they can do and they have all been shocked and saddened by what has happened. “It’s tragic because we have only just had a lot of refreshment work done to the school during the summer break. It was a big investment. The community around here very much looks after its school.”

Plans were being drawn up to provide alternative classrooms for 730 children, with parents warned to keep them at home for at least the rest of the week.

1. Which part of St Mary’s Catholic Technology College was burned to the ground in the fire?

A. The library. B. Sports hall.

C. The science block. D. The passage doesn’t tell us.

2.The underlined word “distressing” in the third paragraph can be replaced by “ ”.

A. excited B. surprised

C. annoyed D. embarrassed

3.From the whole passage, we can know that .

A. the education of England is worse

B. St Mary’s Catholic Technology College had no trouble finding enough classrooms

C. a shortage of money prevented more than 100 firemen controlling the big fire

D. the pupils had to stay at home before the alternative classrooms were found

4.What’s the main idea of the passage?

A. Five boys started a fire that destroyed their school.

B. The firemen failed in controlling the fire.

C. The staff and the children were upset.

D. The school planned to take measures to solve the problem.
