In many parts of the world,cars play an important role in daily life and many societies would not exist without them.So the idea that in 20 years’ time, no one will own cars may be hard to believe.But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by ear manufacturers.

The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program.The team there believes that by 2020 all cars will be computerized,which will mean much saving,no accidents and better use of roads.The superintelligent car of the 21st century will drive itself, and it will not be owned by one individual.Instead,we will have a choice of cars and change them as frequently as we change our clothing.

According to Dr.David Davis,who leads the research team,these predictions are based on the rising cost of the car culture,which had blocked up our cities,polluted our air, and caused more deaths than both world wars put together.

Davis says,cars will be fitted with some intelligent devices to regulate the distance between one car and another.The car will automatically speed up,or slow down,to match the speed of the car in front.Computers are much safer drivers than people,so cars in a road train will be able to drive much closer together than cars driven by people.

By 2010,Dr.David Davis believes,car technology will give motorists a clear view of the road,whatever the weather conditions,by projecting an image of the road ahead on to the car’s windscreen.And by 2020,cars will travel in_convoy,_linked to each other electronically.Cars will be connected by an electronic tow bar to the car in front to form “roadtrains”.“The front vehicle in such a train burns the normal amount.”says Davis.“But all the others in the train would burn about ten percent of the normal amount,and so produce about ten percent of the pollution.”

Three Boys and a Dad

Brad closed the door slowly as Sue left home to visit her mother. Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months. “This will be like a walk in the park.” he’d told his wife. “I’ll look after the kids, and you can go visit your mom.”

Things started well, but just after eight o’clock, his three little “good kids”---Mike, Randy, and Alex --- came down the stairs in their night clothes and shouted “breakfast, daddy.” When food had not appeared on within thirty seconds, Randy began using his spoon on Alex’s head as if it were a drum. Alex started to shout loudly in time to the beat(节拍) . Mike chanted “Where’s my toast, where’s my toast” in the background. Brad realized his newspaper would have to wait for a few seconds.

Life became worse after breakfast. Mike wore Randy’s underwear on his head. Randy locked himself in the bathroom, while Alex shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their eyes. Someone named “Not me” had spilled a whole glass of orange juice into the basket of clean clothes. Brad knew the talk show had already started.

By ten o’clock, things were out of control. Alex was wondering why the fish in the fish bowl refused his bread and butter. Mike was trying to show off his talent by decorating kitchen wall with his color pencils. Randy, thankfully, appeared to be reading quietly in the sitting room, but closer examination showed that he was eating apple jam straight from the bottle with his hands. Brad realized that the talk show was over and reading would be impossible.

At exactly 11:17, Brad called the daycare center(日托所).“I suddenly have to go into work and my wife is away. Can I bring the boys over in a few minutes?” The answer was obviously “yes” because Brad was smiling.

A new eight-kilometre road is under construction that links the port area with the motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometre road tunnels are being built below the central area of the city, one for traffic to the north and the other for traffic to the south .The two tunnels are about 20 metres below the surface and are 12 metres wide, providing for two lanes of traffic in each direction.

In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electronic signs at frequent intervals (间隔). They show traffic conditions ahead, and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and , on the inside of the tunnel , a concrete lining (混凝土衬砌).

Each tunnel is roughly round and the lower part of the tunnel is somewhat flat .The surface of the road lies on the base, which is made of concrete and steel. The drainage system (排水系统), just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel, and at the level of the road surface. Other systems in the tunnel will include emergency phones .

1.Each of the tunnels under construction is ________.

A. eight kilometers long and twenty metres wide

B. four kilometers long and six metres wide

C. four kilometers long and twenty metres wide

D. eight kilometers long and six metres wide

2.Which part of the tunnel in the diagram is used to pipe out extra water?

A. 1 B. 3

C. 5 D. 6

3.Driving in the tunnel, one can know the traffic conditions ahead through ________.

A. the electronic signs B. the lights

C. the trucks and cars D. the emergency phones

4.The passage is mainly about ________.

A. the construction of a road B. the design of a road

C. the construction of two tunnels D. the design of two tunnels

Both men and women are living longer these days in industrialized countries.1.In general, they can expect to live six or seven years more than men. One reason for this is biological.

One important biological factor that helps women live longer is the difference in hormones(荷尔蒙)between men and women.  2.Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

3.They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

4.Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman’s body cells have a tendency(倾向)to age more slowly then a man’s. Others think that a man’s body cells have a tendency to age more quickly. 5.

A. However, women, on average, live longer.

B .The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. Therefore, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control carious body functions.
