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(加強(qiáng)),” 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 (斜線) shown for a sixtieth of a second on a computer screen full of horizontal stripes(水平線).
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.

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

The Great Fire of London started in the very early hours of September 2 th, 1666. In four days it destroyed more than three quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.
The fire started on Sunday morning in the house of the King's baker(面包師) in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery(面包房) into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.
Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect(建筑師), wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them new St Paul's.
The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.
1.The fire began in ________.
[ ]
2.The underlined word “family” in the second paragraph means ________.

[ ]
A.some people lost their lives
B.the birds in the sky were killed by the fire
C.many famous buildings were destroyed
D.the King's bakery was burned down
4.How was the fire put out according to the text?
[ ]
A.The king and his soldiers came to help.
B.All the wooden houses in the city were destroyed.
C.People managed to get enough water from the river.
D.Houses standing in the direction of the fire were pulled down.

(a)There was a strong wind.
(b)The streets were very narrow.
(c)Many houses were made of wood.
(d)There was not enough water in the city.
