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 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 the 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 ______.

People who like travelling have their reasons. They believe that travelling can help them expand their field of view，especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike travelling also have some reasons.
Travelling，in my opinion，does more good than harm. Most importantly，it broadens(使扩大)our mind. We can get in touch with other civilizations(文明)，cultures，customs and ideas.
Through history，most people travelled because of necessity(必要性)－not for pleasure. People travelled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever travelled just for fun of it. In ancient times，for example，rich Romans travelled all the ways to Greece to take part in the Olympic Games，and festivals. Of course，some people decided to travel just out of curiosity(好奇心).They wanted to find out what it looked like beyond the horizon(地平线).Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.
So，travelling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.The underlined word “expand” in Paragraph 1 can be replaced by“___________ ”.
| A．widen | B．protect | C．lose | D．decide |
According to the passage，in the past most people traveled____________.
| A．for fun | B．for knowledge | C．to get experiences | D．to make a living |
How many reasons for travelling are mentioned in Paragraph 3 ?
| A．Three. | B．Four. | C．Five. | D．Six. |
What’s the main idea of this passage?
| A．Different kinds of travelling. |
| B．Travelling enriches our mind. |
| C．Ways to enjoy yourself while travelling. |
| D．The advantages and disadvantages of travelling. |
I’m lying on my back in my grandfather’s orchard (果园)，looking up at the branches above me. It is one of the last days of summer. Already the days are shorter and the nights are cooler. Some kinds of apples are already ripe(成熟的).Others will be ready to pick soon. I think of my grandmother’s apple pie，and how I used to make it with her. She died last year，before the apple harvest，and I have not had her pie since. I really miss her. I hear bees busily humming about，visiting the late summer flowers. The gentle hum of their wings nearly sends me to sleep.
The sky is as blue as my grandfather’s eyes. Above me，big white clouds race across the sky like pieces of cotton blowing in the wind. School starts in another week，and time seems to have slowed down.
“Sophie！” calls my grandfather. “Is that you？”I stand up，take his hand，and tell him all about my day as we walk through the orchard. We talk about apples，and bees，and Grandma. He tells me that he misses her too.
He puts his rough，brown farmer’s hand around my shoulder and pulls me close. “You know，Sophie，”he says，“I spent the morning in the attic(阁楼)，and you’ll never guess what I found. It’s the recipe (烹饪法) for Grandma’s apple pie. I used to help her make it sometimes. I can’t do it all alone，but you used to help her too. Maybe between the two of us，we can work it out. Want to try？”
“But it won’t be the same without Grandma，” I tell him.
“That’s true，”he says，“but nothing is the same without Grandma. Still，I don’t think that she would want us never to have another apple pie. What do you say？” I nod yes，and we walk towards home...towards an afternoon in the farmhouse kitchen，making Grandma’s famous apple pie.We learn from the passage that Sophie .
| A．likes to watch clouds in the attic |

"It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC).
Amphibians (两栖动物) are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972.
"If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats.
But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation（湿润）after winter."
Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit（黑尾豫）. "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says.
But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're volatile anyway," he adds. "But if they fail to breed another year, the population is likely to dip again."According to the passage animals may have problems reproducing this year mainly due to _____.
| A．drought | B．hibernation | C．windier conditions | D．extreme events |
What really worries Peter Brotherton is that ________.
| A．drought is part of nature’s cycle | B．animals are still in hibernation |
| C．soil at this time is far from saturation | D．the population of animals is still unclear |
Which of the following is NOT true of Charlie Kitchin’s words?
| A．Drought has so far continued for two winters. |
| B．Animals could survive one bad nesting season. |
| C．The black-tailed godwit is in danger of extinction. |
| D．40 black-tailed godwits live in the Nene Washes. |
The underlined word volatile in the last paragraph can be replaced by ________.
| A．losing water | B．undergoing changes |
| C．breeding animals | D．suffering flood |
It can be learnt from the text that ______________.
| A．groundwater levels this summer are lower than those of 1976 |
| B．the average rainfall this year has been the lowest since 1972 |
| C．windier conditions could also cause some amphibians’ death |
| D．flooding plays no useful role in wetlands and grasslands |
Brenda Bongos was a happy, artistic girl. She had one big ambition—to play the drums in a band. But one big obstacle lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.
One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.
With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit（成套设备） and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.
It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.
Years later, when asked how she had achieved all this, she thought for a moment, and said: ''If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.''Why did Brenda try to play in the strangest places?
| A．Because she didn't want others to hear her play. |
| B．Because she didn't mean to disturb others. |
| C．Because she didn't have her own room. |
| D．Because she didn’t like her neighbors. |

The website FarmersOnly.com calls itself an online dating and friendship finder. The idea started in the mind of a man, Jerry Miller in Ohio. He wondered how farmers could meet new people who understand the life of a farmer. Jerry Miller is not a farmer but he represents a lot of farmers.
As he tells it, the idea for the site was planted when a farmer told him one day that she was recently divorced and would like to date. But someone would invite her to meet for coffee at nine o’clock at night, when she had to start her day at five the next morning.
So, in 2005, Jerry Miller launched his website. “You don’t have to be a farmer to be on FarmersOnly.com, but you do have to have the good old-fashioned traditional values of America’s Heartland.”
You also have to live in the United States or Canada to be a member of the site. Some services are free, but a full membership costs fifty dollars for a year. As of last week the site listed more than 58,000 members. Many of them are farmers in the United States. Others are students or workers involved in some way with agriculture. Jerry Miller tells us about thirty marriages in the last year have resulted from his website.
Some farmers have also found love through a group, Singles in Agriculture, which was formed as a nonprofit organization in 1986. It organizes gatherings that usually end with a dance, but is not a dating service. The purpose is to support educational and social activities that offer people a chance for friendship. Its website, singlesinag.org, says there are more than 1,000 members across the nation and as far away as France. Jerry Miller started singlesinag.org in order to .
| A．help farmers | B．support traditions |
