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.”
1.Which of the following will be the characteristic of the cars of 2020?
A. The car will speed up out of control.
B. We will own as many cars as we want.
C. All cars will be driven by computers.
D. Cars will produce more pollution than present ones.
2.The leader of the research team believes that the present car culture will change because________.
A. cars play a very important role in daily life
B. many societies would stop functioning without cars
C. cars should not be owned by one individual
D. it causes many deaths to human society
3.The expression closest in meaning to the phrase “in convoy” in the last paragraph is________.
A. in line B. sidelong
C. side by side D. shoulder to shoulder
4.What will happen if cars are joined to each other electro- nically in 2020?
A. Motorists will get a clear view of the road.
B. There will be less pollution caused by car.
C. The weather condition will not have effect on motorists.
D. All trains will bum less fuel than present.

Now in 2019, jazz music is an important part of Indianapolis’ art culture. Jazz clubs around the city still host concerts with local jazz musicians like Rob Dixon and Joel Tucker. One of these clubs, the Chatterbox Jazz Club, still has live jazz seven nights a week.
But the real history of jazz in Indy is much less simple. Along with the Avenue’s culture, jazz music was gone from the streets for many years.
Indiana Avenue was the heart of a neighborhood along the White River. It was a center for black music and live street music.The wealthy avoided this area. So it became a place that poorer families, including many African-American and immigrant (移民) families, moved to.
Jazz prospered in the mix of American cultures around the Avenue in the 1930s and 1940s. But in the 1950s, things changed. After the war, there were projects to make the city beautiful and build a university nearby. Both of these seemed like good changes. However, the new university and buildings caused poorer families to have to leave the area. This destroyed the Indiana Avenue community - and with it, its jazz culture.
After many years, Indianapolis remembered the value of its arts and music culture. It began to bring back lost cultures such as live music on the Avenue. To do so, it began to make new changes. The changes included repairing historic areas like the Avenue. Once again, the high living costs in these historic arts areas pushed low-income families out.
Today there are several old-style jazz clubs where friends can meet up to remember the past or just enjoy a summer evening. It might seem at first that jazz is alive again, but there is a sad reality behind these jazz clubs: Modern Indy jazz is only a shadow (影子) of the lively culture that was once on Indiana Avenue.
1.What does the author mainly want to say in Paragraph 1?
A.Jazz clubs can make big money.
B.Jazz musicians often hold concerts.
C.Jazz music is popular in Indianapolis.
D.Jazz culture is just part of Indianapolis' culture.
2.What does the underlined word “prospered” in Paragraph 4 mean?
A.Disappeared quickly. B.Arrived soon.
C.Recovered soon. D.Developed well.
3.What did Indianapolis do to bring back its lost culture?
A.It rebuilt some old important areas.
B.It invited old jazz musicians to sing in the city.
C.It educated people about the value of music culture.
D.It settled low-income families in the Indiana Avenue community,
4.According to the passage, which of the following about modern Indy jazz is true?
A.Its home culture is gone.
B.Its styles are too traditional.
C.It shows the sadness of the poor.
D.It is no longer a favorite of the young.
