Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for(对…负责) the opening of that first mine.

Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.

Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).

Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.

Which title best expresses the main idea of this passage?

A. Asbestos mined in Canada B. Fireproof matter

C. A “wonder” mineral D. A new roofing material

Johns proved his ability as a salesman by_______.

A. going into roofing business B. carrying asbestos from Italy

C. sending a trained scientist D. showing the use of asbestos gloves

A. show the need for more scientists

B. compare asbestos with other minerals

C. increase the sales of asbestos

D. present facts about asbestos

Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.

The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.

Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.

Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.

Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.

1.Who is Jonathan Patz?

A．A scientist responsible for the climate change.

B．A scientist in charge of the study of the climate change.

C．A professor interested in the climate change.

D．A professor who is a representative from an African country.

2.Which of the following statements is TRUE according to the passage?

A．Climate changes affect different parts of the world in the same way.

B．The ten-day meeting is the first United Nations meeting on climate change.

C．The Kyoto Protocol aims to make smaller the amount of heat-trapping gases into the air.

D．Poor countries are responsible for the global warming.

3.Possible effects from the climate changes include the following EXCEPT ______.

A．crop failures

B．storms

C．more deaths from overheat

D．air pollution

4.According to the health and climate scientists, climate changes have been caused by ______.

A．dry weather

B．cold weather

C．human activities

D．storms

5.We can infer from the passage that ______.

A．climate changes are having a bad effect on human’s health

B．Professor Patz leads the study of climate changes

C．a "heat island"effect large cities experience makes the matter worse

D．rich countries are most responsible for climate changes
