disappears and recuperation begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total more than twelve years. By the age you will also have developed a sleep routine: a favorite hour, a favorite position, and a rule you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
(1).By writing this passage, the writer intends to tell us that _______.
A、sleep is important for good mental and physical health
B、a light sleep is as restful as a deep sleep
C、memory is improved during sleep
D、sleep is relatively unimportant for human beings
(2).The amount of the sleep required may ___.
A、tire an individual mind
B、help infants grow older
C、apply pressure on an executive
D、that they didn’t sleep long
(3).If a person is not allowed to follow his own sleep routine, he will probably _____.
A、never fall sleep
B、not sleep well
C、lost his memory
D、begin to daydream
(4).The author implies that if human beings are kept awake for more than a week the result _____.
A、is hard to imagine
B、will probably be a mental breakdown
C、is difficult to describe
D、will probably be dead
(5).From the amount of sleep Napoleon, Edison, Darwin required, we can conclude ___.
A、 that they were famous
B、 that they were executives
C、 hat they were intelligent
D、 that they didn’t sleep long
Passage 2 Questions 1to 5 are based on the following passage:
Sometimes a book can help change history. One book that certainly did was Uncle Tom’s Cabin, Written by Harriet Beecher Stowe. It was a book that spoke out against slavery.
As Harriet Beecher Stowe wrote her book, there were over3.5 million slaves in the United States. Slaves were usually in the cotton-growing states of the South. The Northern States has ended slavery. Yet most northerners were not strongly against slavery. They did not mind that slavery continued in the South.
Stowe decided to make people understand that slavery was very bad. Each night after putting r six children to bed, she worked on her book. She told the owner. She also told how the slaves tried to run away for freedom. Uncle Tom’s Cabin first came in 1852. Over 300,000 books were sold out in a year.
People had different ideas about the book. In the North, many people finally believed that slavery must be ended after they read the book. In the South, many people were very angry at the people in the North. By 1861 the two parts of the country were at war. The Civil War, which lasted until of cease, was made to happen by many things. Yet Uncle Tom’s Cabin surely played a part. Stowe met President Linclon in 1862. As Linclon took her hand, he said, “So you are the woman who starred the big war.”
1、Before Uncle Tom’s Cabin came out, most Northerners ______.
A、were slaves in the South
B、did not know how bad slavery was
C、kept slaves in their homes
D、understood that slavery was wrong
2、While many Northerners agreed with Harriet Beacher Stowe,______.
A、many southerners wanted war
B、many southerners had not read the boo
C、many southerners were angry at her
D、some slaves tried to run away from North
3、From the text, we can infer that _______.
A、Stowe was a very young woman
B、Stowe’s husband was dead when she wrote the story
C、Stowe wrote her book with stories from her six children
D、Stowe could not work on her book at all during the daytime
4、Uncle Tom’s Cabin was _______.
A、a book about Harriet Beecher Stowe
B、a history book
C、a book that helped change history
D、a book about the American Civil war
5、Harriet Beecher Stowe _______.
A、was a little woman who started the American Civil War together with Abraham Linclon
B、was strongly against the slavery
C、helped some slaves to run away from the South
D、met Abraham Lincoln before the Civil War
Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms.In most nations, for example, weather – balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles.With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation intensive approach needed for accurate, very short – range forecasts, or “Nowcasts,” was not feasible.The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome.Fortunately, scientific and technological advances have overcome most of these problems.Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost.Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information.Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly.As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.
11.The word “exceeded” in paragraph I most probably means ____________.

A.the computer is not used to forecast specific local events
B.the computers are not advanced enough to predict it

D.weather conditions in some small regions are not available
13.According to the passage, the word “Nowcast” (paragraph 3) means _______________.

D.a more advanced system of weather observation
14.According to the passage, ___________ is the key factor to making “Nowcasts” a reality.
A.scientific and technological advances such as radar, or satellites
B.computer scientist
C.meteorologists
