Questions 36 to 45 are based on the following passage.

For many Americans, 2013 ended with an unusually bitter cold spell. November and December（36） early snow and bone-chilling temperatures in much of the country, part of a year when, for the first time in two（37）, record-cold days will likely turn out to have outnumbered record-warm ones. But the U.S. was the exception; November was the warmest ever （38）, and current data indicates that 2013 is likely to have been the fourth hottest year on record.

Enjoy the snow now, because （39）are good that 2014 will be even hotter, perhaps the hottest year since records have been kept. That’s because, scientists are predicting, 2014 will be an EI Niuo year.

EI niuo, Spanish for “the child”, （40） when surface ocean waters in the southern Pacific become abnormally warm. So large is the Pacific, covering 30% of the planet’s surface, that the（41 ）energy generated by its warming is enough to touch off a series of weather changes around the world. EI Ninos are （42）with abnormally dry conditions in Southeast Asia and Australia. They can lead to extreme rain in parts of North and South America, even as southern Africa（43） dry weather. Marine life may be affected too; EI Ninos can （44 ） the rising of the cold, nutrient-rich（营养丰富的）water that supports large fish （45）,and the unusually warm ocean temperatures can destroy coral(珊瑚).

probably a lot sharper in the spring than you are at any other time of the year. A well-known scientist, Ellsworth Huntington (1876-1937), concluded from other men's work and his own among people in different climates that climate and temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.

Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next-best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!

1). Huntington based his conclusions on ___________.

A. work with people in different climates

B. records of temperature changes

C. records of change in his own intelligence

D. all of the above

2). Ellsworth Huntington decided that climate and temperature have _________.

A. a great effect on everyone's intelligence

B. no effect on people's intelligence

C. effect on only a few people's intelligence

D. some effect on most people's intelligence

3). One possible reason why spring is the best season for thinking is that ___________.

A. there are some things making all nature different from before

B. it is neither too warm nor too cold

C. it is more natural for the development of mental abilities

D. it lasts longer than the other seasons

4). The two best seasons for thinking seem to be _____________.

A. winter and summer

B. fall and winter

C. spring and fall

D. summer and spring

5). According to the passage above, vacations from thinking should be taken ___________.

A. as seldom as possible

B. during spring and fall

C. several times throughout the year

D. during the summer

he outside temperature is low. In a similar way there are several gases in the atmosphere which trap(捕捉)the heat produced by the sun and prevent it from escaping. These gases are known as"greenhouse gases"，and the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forests. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide(二氧化碳)in the atmosphere doubles, there will probably be a rise in the earth's temperature of between 1 and 4 degrees. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.

A. the way in which gases are used for keeping plants warm

2. If there were no greenhouse effect, _____.

A. no plants would grow on our planet

B. earth would be thirty degrees colder

A. Burning too much coal and oil produces lots of greenhouse gases.

B. It has become warmer on the earth now than in the past.

C. Gases put into the atmosphere now will affect the earth years later.

D. The temperature in a greenhouse is as high as that in the atmosphere.

4. Suppose the earth's temperature rose by 3 degrees, _____.

A. great harm would be done to mankind

B. the sea level would go by 10 centimetres
