When Babbage was working at Cambridge, a new idea occurred to him. He wanted to construct a calculating machine to work out the solutions（解法）to maths problems not only with correctness but also with a speed beyond the power of any human mind. His machine could solve problems involving（涉及）long rows of figures in one continuous operation（运算）.

In 1822 Babbage exhibited his invention and won a prize from the government. After that, he immediately started to work on a larger machine designed to solve more difficult problems. Although he received some money left by his father, the money was not enough to support his design. He wrote to the government about his plan and was given ￡2500 to start with, a sum worth much more in those days than it is now.

Babbage continued his work in London for four years. Then his health broke down, and he had to take a long holiday abroad. When he returned to London in 1828, he was at the end of his resources. Many bills remained unpaid. His chief assistant and co-workers quarreled with him and left with many expensive tools. For one year no work was done. During this period, Babbage, whose mind was always active, suddenly thought of a completely new idea for the machine. He rushed to meet the government officials to explain his new idea. But this time, they were unwilling to help him. For eight years, they refused to say whether they wanted the machine or not, and their final answer was “No.”

From 1828 to 1839, Babbage held the position of professor at Cambridge very successfully. But his greatest work was the unfinished calculating machine which stood covered in dust in his house. It was the beginning of the modern computer.

60．The machine Babbage designed would solve difficult maths problems _________.

A．in one operation with few mistakes

B．in more than one operation without any mistakes

C．in more than one operation with slight mistakes

D．in one operation without any mistakes

61．Babbage failed to continue his research work in 1828 mainly because _______.

A．he was in poor health B．he almost ran out of money

C．his co-workers argued with him D．he spent all his money on his bills

62．Babage explained his new idea to the government officials, expecting that _________.

A．they would agree to his plan B．they would pay for his new idea

C．they would support him with money D．they would exhibit his new design

63．From the passage, we can infer that __________.

A．Babbage failed to be a famous scientist at Cambridge

B．Babbage always had new ideas but gave them up easily

C．Babbage always needed support from the government officials

D．Babbage was the first designer of the modern computer

If your head is overheating, you are very likely to yawn(打哈欠) soon, according to a new study that has found the main purpose of yawning is to control brain temperature. The study explains several mysteries about yawning, such as why it’s most commonly done just before and after sleeping, why certain diseases lead to too much yawning, and why breathing though the nose often stops yawning.
“Brains are like computers,” Andrew Gallup, a researcher in the department of Biology at Binghamton University who led the study, said. “They operate best when cool.”
He and his co-workers Micheal Miller and Anne Clark did researches on yawning in parakeets(长尾小鹦鹉) , which have relatively large brains, live wild in Australia, often experience temperature changes, and, most importantly, do not yawn when others yawn, as humans and some other animals do.
For the study, the scientists put parakeets under three different conditions: increasing temperature, high temperature and normal temperature. While the frequency(频率) of yawns did not increase under the latter two conditions, it increased greatly when the researchers increased the temperature.
It’s now believed yawning operates like a radiator(散热器).
If air in the atmosphere is cooler than the brain and body temperatures, taking it in quickly cools blood, which in turn cools the brain. The new findings also explain why tired people often yawn. Both tiredness and sleep loss can increase brain temperature, while yawning can cool down the brain.
In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular idea that yawns are just signs of getting tired of something.
49. What’s the best title for the passage?
A. Why don’t people yawn at normal temperature?
B. The yawn explained—it cools your brain.
C. Yawning operates like a radiator.
D. The cause of yawning—finally found out.
50. The main reason why researchers chose parakeets to do the research is that parakeets______.
A. have very large brains
B. live wild in Australia
C. are not affected by others’ yawning
D. experience frequent temperature changes
51. The writer may suggest doing all of the following to stop yawning EXCEPT______.
A. breathing through the nose
B. turning up the heat
C. enjoying some cool wind
D. putting a cold towel on your forehead
52. In which section of a newspaper would you most probably read this passage?
A. Discovery.        B. Education.         C. Health.              D. Mystery.

You need to be of a certain age to understand why so many people in Hollywood are caring about the possible closing down of Metro-Goldwyn-Mayer (米高梅电影公司)．For the past 40 years, its output has been good, but now it is on the ropes, with debts of $ 3.7 billion and will have to sell off its most valuable assets.
In its golden time, MGM stood for something．If Warner Brothers meant social dramas and gangster movies, and Disney meant cartoon films, then MGM was healthy fantasy．This business model found its most glorious expression in its musicals of the post-war era．It also featured such many famous stars as Fred Astaire, Frank Sinatra, Gene Kelly and Judy Garland.
But MGM had always put its hopes on the quality of stars it could attract．From the time MGM became a company in 1924, the studio and his associate proved themselves good at creating big names.
For 35 years, this worked well enough, but the growing power of television disturbed Hollywood．MGM continued to throw money into making gorgeous-looking musicals, but despite some big successes audiences gradually started to drift away．Throughout the sixties, MGM's decline set in．Things went from bad to worse．In 1973, MGM stopped distributing its own films．Since then, the Lion's roar has been reduced to a whimper (呜咽).
How far MGM has fallen can be shown by its recent releases．This was a studio that for years offered a reliable supply of first-class films．Yet last year its total output was three．To make it worse, all were co-produced with other studios．And this year? Only one so far, and maybe the last.
What now? MGM will probably be sold, though recent buyers have been cautious about a price thought to be around $ 2 billion.
【小题1】MGM is becoming the focus in Hollywood because it _______．

A．has more supporters	B．has produced good films
C．might be closed down	D．has lost all its assets

【小题2】What can we learn about MGM from the text?

A．It has been sold out for around $ 2 billion.

B．The Internet was a factor causing its decline.

C．It only produced three films by itself last year.

D．It made a wrong decision for its development.

【小题3】What's the main idea of the text?

A．The past glories of MGM．	B．The musicals made by MGM.
C．The decline of MGM．	D．A historical decision by MGM

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.
Lewis and his co-workers carried out their study by videotaping(录像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are that it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”
【小题1】Parents with large families ask fewer questions at dinner because ______.

A．they are busy serving food to their children

B．they are busy keeping order at the dinner table

C．they have to pay more attention to younger children

D．they are tired out having prepared food for the whole family

【小题2】By saying “Middle children are invisible” in paragraph 3, Lewis means that middle children ______.

A．have to help their parents to serve dinner

B．get the least attention from the family

C．are often kept away from the dinner table

D．find it hard to keep up with other children

【小题3】Lewis’ research provides an answer to the question ______.

A．why TV is important in family life

B．why parents should keep good order
