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 .

It looks like a mobile phone, but the service is much cheaper. It acts like a mobile phone, but only in your own city. Beyond the city walls, it’s useless.
“Little Smart”, also called “xiaolingtong”, has always been compared to mobile phones. But actually, it is more like one of those cordless phones(无绳电话) used around the home. The only difference is that this one reaches much further than from the bathroom to the living room. It can travel across an entire city.
Cheap costs are the main reason for the success of Little Smart. It costs 25 yuan a month for the line and about 0.1 yuan per minute to use. A mobile phone, on the other hand, can cost four or five times as much. What’s more, unlike mobile phones, there’s no fee(费) for incoming calls. So these low charges have attracted many users.
But, Little Smart is not really that smart. Users often complain about its bad voice quality. And there are not as many stations to pick up its signals as there are for mobiles. “I couldn’t receive a phone call if I was on a bus,” said Li Ping, a user in Hangzhou. “It worked fine when I stood still, but there were breaks in signal when I was moving.”
Scientists are trying to make Little Smart more user-friendly. Messaging and Internet access(接入) have been added to the service. And the latest Little Smart handset even has color screen.Why is Little Smart popular in China?
| A．It looks like a mobile phone. | B．The service is much cheaper. |
| C．There is no fee for incoming calls. | D．All of the above. |
How is the charge of Little Smart?
| A．About 10 fen per minute to use. |
| B．It costs four or five times more than a mobile phone. |
| C．It only costs 25 yuan each month. |
| D．There’s no fee for calls. |
Why are users not satisfied with Little Smart?
| A．They can’t hear each other clearly out of the city. |
| B．There are so few stations for Little Smart to pick up its signals. |
| C．When you use it, you must stand up. |
| D．The charges are low. |
The underlined word “handset” in the last paragraph means “______”.
| A．the hand bag | B．telephone | C．service | D．mobile phone |
What can we infer from the passage?
| A．It’s wrong to say that Little Smart is smart. |
| B．Scientist are trying to make Little Smart smaller. |
| C．Little Smart will be better than today. |
| D．People will change Little Smart into a mobile phone. |
People travel for a lot of reasons. Some tourists go to see battlefields or other historic remains. Others are looking for culture, or simply want to have their pictures taken in front of famous places. Most European tourists are looking for a sunny beach to lie on.
Northern Europeans are willing to pay a lot of money for the sun because they have so little of it. People in cities like London, Copenhagen and Amsterdam spend much of their winter in the dark because the days are so short, and much of the year it rains. This is the reason why the Mediterranean has always attracted them. Every summer many people travel to Mediterranean resorts (度假胜地) and beaches for their vacation. They all come for the same reason. Sun!
The huge crowds mean lots of money for the economies of Mediterranean countries. Italy's 30,000 hotels are booked without a break every summer. And 13 million people visited French beaches, parks, and roadsides. Spain's long sandy coastline attracts more people than anywhere else. 37 million tourists visit there yearly, or one tourist for each person living in Spain.
But there are signs that the area is getting more tourism that it can deal with. The Mediterranean is already one of the most polluted seas on earth. None of this, however, is ruining anyone's fun. Obviously, visitors don't go there for clean water. They allow traffic jams and endure crowded beaches. They don't even mind the pollution. No matter how dirty the water is , the coastline still looks beautiful. And as long as the sun shines, it's still better than sitting in cold Berlin, London, or anywhere else. The writer seems to imply that Europeans travel mostly for the reason that _____.
| A．they want to see historic remains |
| B．they wish to escape from cold, dark and rainy days |
| C．they would like to take pictures in front of famous places |

Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2)citrus （柑橘）fruits and tomatoes; (3) potatoes and other fruits and vegetables ; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal (谷物), rice is also in this kind of foods; (7) Butter or something like butter.
People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
There are two problems, then, in feeding the large number of people on earth. The first thin g is to find some ways to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kind of food to make them grow to be strong and healthy.
