I love science and science fiction. Like many science fiction fans, I am fascinated by the possibility of time travel. However, one must combine romance with reasoning and look into the chances of time travel critically.

First of all, we must remember the whole universe is in motion. If we want to go back to yesterday, our "time machine" has to move back in time and space. If someone claimed he was at home when he suddenly travelled 200 years back in time, he either had an illusion or made the story up. Two hundred years ago, Earth was in a different place in space, so how can you travel back 200 years without moving in space? Don't get me wrong. I am not knocking the genius of science fiction writers. H.G. Wells's "The Time Machine" is a great work of fiction, but that’s all. I have read many other time travelling science fiction stories since reading H.G. Wells, but none address this problem of displacement.

My own argument for the impossibility of time travel is that physical states of the past no longer exist and those of the future are not here yet. To be able to move back and forth in time requires everything that has happened, is happening, and will happen everywhere in the whole universe at every single moment in time－past, present, and future－to be stored as a "reality" somewhere－like the save game file of a computer game that contains every single byte of information of the game at the point it was saved, but you would need an almost extremely large file and almost extremely many of them－so it can be re-entered and communicated with, and not just light signals for viewing. To me, I don’t buy it.

1.Which of the following can be the best title?

    A. How to make time travel possible?

    B. Why am I fascinated by time travel?

    C. Why do I think time travel is not possible?

    D. How to explain the possibility of time travel?

2.What’s the meaning of the underlined word “illusion”?

3. According to the author, which of the following is RIGHT?

    A. We can go back to the past by time travel.

    B. People can travel to the future by moving in space.

C. “The Time Machine” is nothing more than a science fiction.

    D. Everything that happened, is happening and will happen can be stored somewhere.

4.In the author’s opinion, time travel might be possible if                            .

    A. people could combine romance with reasoning

    B. people could stop the movement of the whole universe

C. people could use time machine under the instruction of H.G. Wells

    D. people could “save” everything in the past, present and future in a certain space

When Paul was a boy growing up in Utah, he happened to live near a copper smelter(炼铜厂), and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.

Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was “No.”

Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn’t get his idea accepted.

Paul later got married and had some kids. But his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, “It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges.” Under the cover of darkness, he went secretly into the wasteland and started planting.

And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against the plain common sense. Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.

Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.

1.  When Paul was a boy, _____.

A.  he had decided never to leave his hometown

B.  the economy of Utah depended wholly on the copper smelter

C.  no laws were made to protect the environment against pollution

D.  he determined to stop the copper smelter polluting the area

2.  Why did Paul go to college to study the science of plants?

A.  He wanted to find out the best way to save the area himself.

B.  He was interested in planting trees since he was young.

C.  He wanted to get more knowledgeable people to help him.

D.  He thought his knowledge would make his advice more persuasive.

3.  What does the underlined phrase “the plain common sense” probably refer to?

A.  That it was impossible for trees to grow on the wasteland.

B.  That his normal work and life would be greatly affected.

C.  That no one would like to join him in the efforts.

D.  That he had to keep everything he did secret.

4.  The main idea of the passage is that _____.

A.  action speaks louder than words

B.  perseverance will work wonders

C.  God helps those who help themselves

D.  many hands make light work

Star hurdler Liu Xiang returned home last night after spending about three months in the United States for foot operation and recovery.

Liu and coach Sun Haiping were followed away by officials after arriving at Shanghai Pudong airport at around 6 : 30 p. m. , and said nothing to the waiting media.

Liu went straight to the Xinzhuang training base in Shanghai, where he will start on the comeback (恢复) through rehabilitation (复职) and training.

Feng Shuyong, vice-director of China's Athletics Administrative Center, said a group of experts is on standby at the training base to help with Liu's recovery.

"The experts will give Liu a full check-up tomorrow or the day after and advise regularly on rehabilitation in the coming months," Feng was quoted by qq. com as saying.

The foot injury forced defending champion Liu to quit from the 2008 Beijing Olympics last August after "he limped out of the Bird's Nest in the first round of the men's 110m hurdles, bitterly disappointing adoring home fans.

The 25-year-old Athens Olympic and world champion had successful foot surgery in December at the Memorial Hermann-Texas Medical Center in Houston, and had four calcium deposits (钙物质) removed from his right Achilles tendon (跟腱).

He spent the next three months in Houston for rehabilitation and basic training under the guidance of doctors there.

"His recovery is better than we expected. Doctors believe that after three months' rehabilitation and training, he has actually achieved the level of recovery that generally needs four months," Feng said.

Liu will, however, be absent from the ongoing annual Chinese People's Political Consultative Conference (CPPCC) meeting due to the recovery process. Feng said Liu is paying close attention to the meeting through the Internet, and closely following issues such as athletes' education and life after retirement.

It is the second time Liu has asked for leave from the annual session after being elected to the CPPCC: He did not attend last year's meeting because he was at a key competition in Spain.

1.The best title for the passage is _______.

A. Fate and Challenge                                                    B. Liu Xiang Returns after Operation Success

       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
