There is a definite possibility that the climate of the world may be changing. Some scientists imagine that this could even mean the beginning of another ice age. The effects of such a change in climate on the human population of the world would be startling（惊人的）.

   Recent research suggests that the general warming trend of the past hundred years or so may be coming to an end. During the past ten years, meteorologists tell us the average temperature of the Earth has dropped about one degree Fahrenheit. This does not seem like much, but it could have effects on wind and rain patterns which influence the overall weather picture. If these patterns change a lot, it could mean that certain regions of the world may continue to have long droughts while others will possibly suffer from widespread flooding.

What regulates（调节）the climate is not exactly known. Meteorologists believe that clouds may be an important factor in regulating the amount of solar heat held by the Earth, which in turn determines the temperature of the planet. Another possibility is that man’s industrial and agricultural methods may be affecting the natural weather patterns. However, the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the world’s population.

Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life.

Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregivers. This is how babies learn to connect and communicate with other human beings.

One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.

The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.

Another study shows how mothers can strongly influence social development and language skills in their children.

Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere (干涉) unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression (消沉).

The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.

These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression.

According to the passage, which of the following is NOT the factor that influences intelligence development in babies?

  A. The environment.                                     B. Mother’s sensitivity.

C. Education before birth.                        D. Their peers (同龄人)

What is the purpose of the experiment in which newborn babies heard the stories?

  A. To prove that babies can learn on the first day they are born.

  B. To prove that babies can learn before they are born.

  C. To show mothers can strongly influence intelligence development in their babies.

  D. To indicate early education has a deep effect on the babies’ language skills.

Which group of children did the worst in tests of language skills?

  A. The children of women who did not suffer from depression.

  B. The children of depressed but caring mothers.

  C. The children of depressed mothers who cared little for their children.

  D. The children with high communication abilities.

What is the main idea of the passage?

  A. Scientific findings about how intelligence develops in babies.

  B. Scientific findings about how the environment has an effect on babies’ intelligence.

  C. A study shows babies are not able to learn things until they are five or six months old.

  D. Scientific findings about how babies develop before birth.


Should we try to contact and make friends with other beings in the universe? Certainly not，says British physicist Stephen Hawking．
“If aliens（creatures from other planets）ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25．
The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets．
“Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach，”warned Hawking．
On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”
Hawking’s concerns have frightened some people and been met with disagreement from other researchers．Paul Davies, author of the book Renewing Our Search for Alien Intelligence，thinks Hawking’s reasoning is wrong.
He argues that since Earth is about 4.5 billion years old，if intel1igent life is likely , communities of other beings may have been there for a very long time．
“If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago．
Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).
68. What is the article mainly about? 
A. Other life forms coming to our planet．
B. Scientific evidence of other life forms．
C. Earth as the only place where human beings can survive．
D. Hawking’s belief that other life forms may exist in the universe．
69. Which of the following ideas is opposed to Hawking’s view?
A. Other life forms exist in the universe．
B. 0ther life forms may be more intelligent than human beings．
C. We should try to contact other 1ife forms from other planets．
D. Other life forms may exist in more than one part of the universe．
70. Paul Davies didn’t agree with Stephen Hawking ,believing that ________．
A. the universe is running out of resources
B. humans are the best creatures in the universe.
C. it is a good idea to avoid meeting with other life forms   
D. Davies doesn’t think it proper to compare aliens with Columbus
71. Hawking referred to Christopher Columbus as an example to ____．
A. inspire interest in the universe      
B. draw attention to other planets in the universe
C. warn people to watch out for other life forms
D. urge further exploration of the universe~

The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).

????????????? Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.

The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.

????????????? During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.

????????????? This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.

The engineering firm of Ove? Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.

1.What’s the meaning of “complex” in the second paragraph??

A. Something that is difficult to understand.

B. A group of buildings together in one place.

C. A group of things that are connected.

D. A mental state that is not normal.

2.How is fresh air from outside drawn out?

A. By fans.????????????? ????????????? ?????? B. Via ceiling vents.????????????? ?????????????

C. Through chimneys.????????????? ?? D. Via ceiling vents and through chimneys.

3.What is NOT the factor that makes Eastgate Building work well?

A. Skies without clouds.

B. Little dampness.

C. Daily rapid temperature changes

D. Seasonal rapid temperature changes.

4.In general, how is the daily temperature of the building?

A. It changes in a certain range with some exception.

B. It changes from one extreme to another.

C. It remains the same without any exception.

D. It is hard to endure.

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

A. The engineering firm of Ove Arup&Partners.

B. How air-conditioning works.

C. Fans make Eastgate Building’s temperature comfortable.

D. How Eastgate Building’s temperature control system works.
