Edmund Halley was an English scientist who lived over 200 years ago . He studied the observations of comets (彗星) which other scientists had made . The orbit（轨道） of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.
However , Halley had a friend named Newton, who was a brilliant (有才华的) mathematician .Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse (椭圆) .
Now Halley set to work .He figured out the orbits of some of t
he comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart (相隔).
This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times .The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested .In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.Edmund Halley figured out the orbit of .
| A．some different comets appearing several times |
| B．the same comet appearing at different times |

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what "keeping up with the Joneses" is about. It is the story of someone who tried to look as rich as his neighbors.
The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $ 125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhoodoutside New York City.. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They had to move back to an apartment in New York City. Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it "Keeping up with the Joneses” because "Jones" is a very common name in the United States. "Keeping up with the Joneses" came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.
People never seem to get tired of keeping up with the Joneses. And there are "Joneses" in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.Some people want to keep up with the Joneses because they ______.
| A．want to be as rich as their neighbors |
| B．want others to know or to think that they are rich |
| C．don't want others to know they are rich |
| D．want to be happy |
It can be inferred from the story that rich people like to ________.
| A．live outside New York City |
| B．live in New York City |
| C．live in apartments |
| D．live with many neighbors |
What's the author's attitude to keeping up with the Joneses?
| A．Negative. | B．Positive. | C．Supportive. | D．Objective. |
Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no.
“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.
His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM,转基因的）crops．Just last week, EU（欧盟）member nations were discussing whether or not to import GM sweet corn from the US．
Ever since people started farming, they have tried to crossbreed（杂交）plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other．
But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.
This means they can make crops more productive and resistant to disease by adding genes from other species．They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.
At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.
Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops．
People in China are also getting worried about GM foods. More than 70 percent of the
country’s soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them. Which is the best title for the passage?
| A．Harmful GM foods | B．Advantages of GM foods |
| C．GM foods, a health risk? | D．the Techniques of GM foods |
Why has Zambia refused the American free maize?
| A．they decide to follow EU member’s advice |
| B．they are concerned about the safety of GM foods |
| C．they care little about the problem of starvation |
| D．they are too proud to accept free offer |
It has been proved that _________.
| A．GM foods are harmful to people’s health |
| B．GM food is no better than naturally produced foods |
| C．only related plans could be crossed with each other |
| D．GM techniques can increase the production of crops |
Which of the following statement is TRUE?
| A．GM foods are a health risk. |
| B．Only Zambia worries about the safety of GM foods . |
| C．China’s government hasn’t taken any action about GM foods. |
| D．Some experts believe human bodies can absorb genetic material from GM foods. |
What’s the author’s attitude towards GM foods?
| A．Supportive. | B．Neutral. | C．Doubtful. | D．Critical. |
When times get tough, we all look for ways to cut back. When we’re hungry, we eat at home instead of going out. We take buses instead of taxis. And we wear our old designer jeans just a few months longer. With college expenses at all-time highs, high school students are eager to do anything to cut the cost of a university education.
One cost-cutting proposal is to allow college students to get a bachelor’s degree in three years instead of four. Educational institutions have been actively exploring ways to make the learning process more efficient. But there’s a question: Would the quality of undergraduate(本科生)education suffer? Few US universities have formally approved a “three-year degree” model.
I doubt that mainstream North American colleges will carry out a three-year curriculum(课程) any time soon. For one thing, most universities already allow highly qualified students to graduate early by testing out of certain classes and obtaining a number of college credits(学分). In addition, at famous universities, the committee who determine which courses are required and which courses are electives are unlikely to suddenly “throw out” one quarter of the required credits. Professors will resist “diluting(稀释)” the quality of the education they offer.
In my opinion, a quality four-year education is always superior to a quality three-year education. A college education requires sufficient time for a student to become skilled in their major and do coursework in fields outside their major. It is not a good idea to water down education, any more than it’s not a good idea to water down medicine. If we want to help students find their way through university, we should help them understand early on what knowledge and skills they need to have upon graduation. We should allow students to test out of as many courses as possible. We should give them a chance to earn money as interns(实习生)in meaningful part-time jobs that relate to their university studies, such as the five-year co-op program at Northeastern University.

In the US and Britain, the slogan around colleges was “Save water. Shower with a friend.” Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit (IC) card reader at each tap shows the time. No money, no water. The benefits of the new system can be seen with the old system, which charged 1 Yuan for each person regardless of time in the shower. The university used about 320 tons of water daily under the old system, but only 160 tons now.
Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they’re still covered in soap. They have to ask the bathhouse worker to help them buy extra time.
“It’s a flaw in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students’ suggestions that they be allowed to pay after they’ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.
Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.
Some even used the hot water to wash their clothes. “In my experience, 10—20 minutes is enough,” said Dai Zhihua, a third-year student who usually takes 8 minutes.
A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 Yuan per minute. One male student responded by setting a record with a two-minute shower.According to the passage, which of the following is NOT true?
| A．Students buy the time of their showers. |
| B．The clock times the student’s bathing except when the bather pauses for soap. |
| C．If money runs out, there will be no water. |
| D．Having finished bathing, the student has to pay for it. |
The underline word “flaw” (Paragraph 3) most probably means __________.
| A．fault | B．advantage | C．pity | D．perfection |
Since the new system has performed, __________ of water can be saved.
| A．a quarter | B．one third | C．one half | D．two thirds |
It can be inferred from the passage that __________.
| A．the new operation can raise students’ environmental awareness |
| B．the new operation can solve the water crisis |
| C．a similar operation has been set in other universities |
| D．the university has saved a lot of water by using the new system |

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:
“ENTER NAMES
VOYAGE １
VOYAGE ２
Mark’s finger flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED.
START TRANSPORT PROGRAM.
AUTO-RETRIEVE INITIATED(自动回收程序已启动).”
The screen turn even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒)，until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed：
“TRANSPORT SUCCESSFUL．

| D．In an information processing center. |
Mark thought “SPACE TRANSPORTER” on the screen was the name of ________.
| A．a computer game | B．a company website |
| C．a software producer | D．an astronomy program |

| B．He didn’t like the loud noise and light. |
| C．He didn’t want to play games. |
| D．He was afraid something dangerous might happen. |
