The Mayan Indians in Central America and Pacific Islanders also discovered how to make paper, but their knowledge never spread to the rest of the world.

Burning the midnight oil before an exam or interview has an opposite effect according to a research which found that sleep is necessary for memories to be “downloaded” into the brain.

“A good night's sleep within 30 hours of trying to remember a new task is a necessary condition of having good recall in the weeks ahead，” scientists have found.

“We think that getting that first night's sleep starts the process of memory consolidation(加强)，” said Robert Stickgold, a sleep researcher at Harvard Medical School who conducted the latest study.

“It seems that memories are normally washed out of the brain unless some process nails them down. I feel uncertain that sleep is one of those things that do the nailing down，” Professor Stickgold said.

Professor Stickgold's team trained the 24 people to tell the direction of three diagonal bars (斜线) shown for a sixtieth of a second on a computer screen full of horizontal stripes(水平线)．

Half the subjects were kept awake that night, while the others slept. Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.

Those who slept the first night were much better at remembering the task while the second group showed no improvement in spite of enjoying two nights of catch－up sleep.

A further study by scientists at the Medical University at Lubeck in Germany showed that memories are laid down in two stages during the night. The first is during the deep, so－called “slow wave” sleep, which usually takes place in the first half of the night. The second, and less important stage happens during the periods of dreaming or “rapid eye movement (REM)”. When people don't sleep well in the first half of the night, their memory consolidation is almost the same as having no sleep at all.

1. Which of the following statements is CORRECT according to the first paragraph?

A. It is necessary to burn the midnight oil before an exam or interview.

B. Sleep speeds up the loss of memory.

C. Man should have a good sleep if he wants to keep a good memory.

D. Staying up late will make you better prepared for an exam or interview.

2. It can be inferred from the fourth paragraph that________.

A. some process helps memories to be washed out of the brain

B. Professor Stickgold is doubtful about whether sleep can make memories worse

C. some memories normally influence the function of the brain

D. sleep may can improve the condition of memories

3. How was the research conducted by Professor Stickgold?

A. The subjects were divided into two groups.

B. All the subjects were kept awake for 3 nights.

C. One group slept at the first night but was kept awake the next two nights.

D. One group was kept awake for 3 nights but the other slept for the second and third nights.

4. What was the study result of the scientists' at the Medical University at Lubeck?

A. REM sleep is not important at all for the consolidation for memory.

B. Intellectual performance mainly depends on the slow wave sleep period.

C. When people sleep poorly in the first half of the night, it is almost the same as having no sleep at all.

D. REM sleep is as important as slow wave sleep in terms of memory recall.

5. The BEST title of this passage is “________”．

A. Sleep Necessary for Memories

B. The Importance of the First Stage of Sleep

C. Studies Made by Scientists About Sleep

D. The Scientists' Achievement in Sleep Research

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive , people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.

Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock. During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.

People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas, instead of keeping livestock on the first floor builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy saving.

House building becomes a great challenge to building designers and energy engineer. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy saving houses.

1.What did people begin to consider as electricity was no longer cheap?

A．The climate of their areas. B．The energy for their houses.

C．The fashions for their houses. D．The building materials for their houses.

2.People in some areas gain a source of heat by _________.

A．keeping their livestock downstairs

B．protecting their livestock from the cold

3.The underlined words “natural law ” in the third paragraph refer to the fact that ________.

A．heat raises the temperature in the houses

B．heat goes in the upward direction

C．heat goes up if temperature is raised

4.From the passage, we can conclude that _______ .

A．people will no longer consider building materials in the future

B．energy saving buildings will become more popular in the future

C．almost all people will move into the houses heated by large rocks

D．energy engineers will devote themselves only to modern technology

5.What is the meaning of the underlined word “livestock” ? _______ .

A．animals raised especially for economical benefits B．furniture
