   As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.

   When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.

    There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.

    A. there are many rich valleys and large fields

    B. farmers are producing more crops than before

    C. people are living longer due to better living conditions

    D. new lands are being made into farmlands

57. The author says that in areas with large populations, land might be more productively farmed if _____.

   A. the land was divided into smaller pieces

   B. people moved into the countryside

   C. industrial methods were used in farming

   D. the units of land were much larger

58. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.

   A. growing new types of crops

   B. irrigation and dry-farming means

   C. providing fertilizers 

   D. destroying pests and diseases

59. Why is the land divided into tiny units in some areas?

   A. There are too many people living there.

   B. It saves more natural resources there. 

   C. It prevents crops from serious diseases there.

   D. Farmers can grow various kinds of crops there.

60. Why do some people use dams to hold back waters from great rivers?

   A. To develop a new kind of dry-farming methods.       

   B. To prevent crops from floods.

   C. To provide water and electricity in all seasons.          

   D. To water poor lands in bad weather.

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.

    Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.

　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.

　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

70. Pollution of water is noticed________.

　　A. when the first organisms are affected　     

B. when a good many fish and birds die

　　C. when poisonous things are poured into water　

D. as soon as the balance of nature is destroyed

71.The living things die because there is no ________in the lake or river.

　　A. water　　　　　            B. fish            　 C. poison　　　　　   D. oxygen

72. Which of the following is harmful according to the passage?

　　A. Organisms               　B. Plants and plankton in the water

　　C. Waste water from cleaning    D. Industrial waste made clear before flowing into the water

73. The way to stop water pollution is to________.

　　A. realize the serious situation clearly

　　B. put oxygen into the river

　　C. make the waste material harmless before flowing into the water

　　D. make special room in the sea for our rubbish

As far back as 700 B. C, man has talked about children being cared for by wolves. Romulus and Remus, the legendary（传说的）twin founders of Rome, were said to have been cared for by wolves. It is believed that when a she-wolf loses her litter, she tries to get human child to take its place. This seemingly foolish and unreasonable idea did not become believable until the late nineteenth century when a French doctor actually found a ten-year-old boy having nothing on wandering in the woods. He didn’t walk upright, could not speak understandably, nor could he relate to people. He only growled（嗥叫）and stared at them. Finally the doctor won the boy’s confidence and began to work with him. After many long years of devoted and patient teaching, the doctor was able to get the boy to clothe and feed himself, recognize and say a number of words, as well as write letters and form words.

A research by the National Center for Health Statistics is seen as an important confirmation of the“Hispanic mortality paradox（西班牙裔死亡率悖论）.”

On average，Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years，compared with 78.1 for whites，72.9 for blacks and 77.7 years for the total population.

The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites.“Mortality is very correlated with income，education and health care access，”says Elizabeth Arias，author of the report.“You would expect the Hispanic population would have higher mortality，”in line with the black population.

The Hispanic paradox has been documented for more than two decades，but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer.

“We don’t know，”says David Hayes-Bautista，director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine.“We thought it was a problem in the data，but we can pretty much say this is real.”

Potential factors:

·Culture and lifestyle.  Support from extended family and lower rates of smoking and drinking.Latino groups in particular have very strong family and social ties.

·Migration.  The“healthy migrant effect”argues that healthy people are more likely to emigrate. And when immigrants become ill，they might return home and die there.

    Solving the puzzle may help the nation deal with health care issues because Hispanics use health services less—they make fewer doctors visits and spend less time in hospitals，Hayes-Bautista says.“It’s clearly something in the Latino culture，”he says.

In 2006，Hispanics’life expectancy is           years longer than the average of the total population.

    A. 2.5                 B. 7.7               C. 2.9              D. 80.6

What does the underlined word“outlive”in the second paragraph probably mean？

A. To live longer than…                      B. To live shorter than…

C. To die out.                              D. To expect to live.

What is the main idea of paragraph three？

A. Hispanics were born better than whites.

B. Morality is closely related with health care access.

C. Whites should have longer life expectancy.

D. Even experts can’t explain the phenomenon.

What is Mr.Hayes-Bautista’s opinion about the paradox？

A. He supports there is a problem with the data.

B. He intends to trust the cultural factor.

C. He believes in the“healthy migrant effect”.

D. He thinks health care the most important factor.

Which of the following inferences is true according to the passage？

A. Black people suffer the lowest social status in America.

B. Hispanics might have healthier ways of life.

C. Only healthy people can immigrate into America.

D. White people don’t have strong family ties.
