Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening. 

One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own. 

Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature. 

Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night. 

Which of the following statements is NOT true? 

A. People who like country things prefer to live outside the city. 

B. People who work in London prefer to live in the country. 

C. Because of certain disadvantages of living outside London, some people who work in London prefer to live inside London.

What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)may be able to put the tooth back in for you, but you have to get to the dentist first．In the meantime, you have to store the tooth so that it will stay healthy．
The simplest thing to do is put the tooth back into your mouth, or you could put it in milk．Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth．He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液)．He also tried, just drying the teeth in the open air．He used teeth that had to be removed from people’s mouths for various reasons．The teeth were put into one of the solutions(溶液)or stored in the air for one hour．Then cells from the root of the teeth were scraped-off the teeth．Dr．Courts and the others then studied how healthy these cells were．
The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth．However, few people keep cell-culture medium handy at home or in school．
The next best thing was milk．But Dr．Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽)in the mouth．For some people, though, this is just too painful or upsetting．So milk will do, until you get your tooth (and your mouth)to a dentist．

Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.

The oldest known transport wheel was discovered in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around. But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.

In the mid-1700s, a Frenchman came up with a new design of road — a base layer (层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs (the central part of a wheel) came into being, followed by the pneumatic type (充气轮胎） in 1846.Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.

1.What might explain why transport wheels didn’t become popular for some time?

A. Few knew how to use transport wheels.

B. Humans carried farming tools just as well.

C. Animals were a good means of transport.

D. The existence of transport wheels was not known.

2.What do we know about road design from the passage?

A. It was easier than wheel design.

B. It improved after big changes in vehicle design.

C. It was promoted by fast-moving vehicles.

D. It provided conditions for wheel design to develop.

3.How is the last paragraph mainly developed?

A. By giving examples.                                                               B. By making comparisons.

C. By following time order.                                                        D. By making classifications.

4.What is the passage mainly about?

A. The beginning of road design.

B. The development of transport wheels.

C. The history of public transport

D. The invention of fast-moving vehicles.
