In parts of Africa, the sky is filled with a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts that are traveling across the continent eating everything in their path.

And in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if www..comthey can catch and kill 50 kilograms of locusts. The radio station is in one of Senegal’s worst affected regions.

This is West Africa’s biggest locust disaster in 15 years, and it is moving east, causing huge damage to crops. As they move, they breed, and increase their number and will soon threaten Sudan in the northeast of Africa. Some say it could reach Asia.

Experts say the great damage to crops in areas already suffering from food shortages and war could cause many people to go hungry. Governments in the region are not well equipped to fight the pest.

Although leaders of 12 countries have agreed on a plan, it is not expected to be enough. “We are now treating 6,000 hectares per day with pesticide, but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster,” said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.

Requests are being made for international aid, which is the only way to limit the crisis, the UN’s Food and Agriculture Organization warned.

       In so many ways, cyberspace(网络空间) mirrors the real world.People ask for information, play games, and share hobby tips.Others buy and sell products.Still others look for friendship, or even love.

       Some Internet users want more than just someone to chat with.They’re looking for serious love relationships.Is cyberspace a good place to find love? That answer depends on whom you ask.Some of these relationships actually succeed.Others end in tears.

       Unlike the real world, however, your knowledge about a person is limited to words on a computer screen.Identity and appearance mean very little in cyberspace.Rather, a person’s thoughts or at least the thoughts they type are what really counts.So even the shyest person can become a chat-room star.

       Usually, this “faceless” communication doesn’t create problems.Identity doesn’t really matter when you’re in a chat-room discussing politics or hobbies.In fact, this emphasis on the ideas themselves makes the Internet a great place for exciting conversation.Where else can so many people come together to chat?

       Supporters of online relationships claim that the Internet allows couples to know how intelligent they are first.Personal appearance doesn’t get in the way.

       But critics(批评者)of online relationships argue that no one can truly know another person in cyberspace.Why? Because the Internet gives users a lot of control over how others view them.Internet users can carefully choose their words to fit whatever image they want to give.And they don’t have to worry about what their “non-verbal ” communication is doing for their image.In a sense, they’re not really themselves.All of this may be fine if the relationship stays in cyberspace.But not knowing a person is a big problem in a love relationship.With so many unknowns, it’s easy to let one’s imagination “fill in the blanks”.This surely leads to disappointment when couples meet in person.How someone imagines an online friend is often quite different from the real person.

       So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll, “Life in the real world is far richer than anything you’ll find on a computer screen.”

Which would the critics of online relationships most probably disagree to?

       A.Nobody can truly know another person in cyberspace.

       B.Internet users can choose words to create any image they like.

       C.The Internet allows couples know how intelligent they are.

       D.In a sense, Internet users are not really themselves.

Even the shyest person can become a chat-room star because what really counts is a person’s ______.

       A.non-verbal communication    B.thoughts typed on the screen

       C.knowledge and appearance    D.identity shown in the chat

The underlined word “This” (Paragraph 6) refers to ______.

       A.having exciting conversations online

       B.forming personal relationship in cyberspace

       C.imagining online friends with so many unknowns

       D.knowing a person in a love relationship

What’s the writer’s attitude towards finding love in cyberspace?

       A.Positive         B.Negative        C.Interested      D.Disinterested

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, which are taken seriously, not only by government but also by car 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 2030 all cars will be computerized, which will mean much saving, no accidents and better use of roads. The super-intelligent 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 (自动的) 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 2020. 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 2030, cars will travel in convoy, linked to each other electronically. Cars will be connected to the car in front, just like a train. “The front vehicle in such a train burns the normal amount of fuel.” 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.”

We know from the passage that governments and car manufacturers_______.

A. are devoted to the technological revolution in car industry

B. consider the predictions seriously

C. do not believe the prediction that no one will own cars by 2030

D. have put the super-intelligent car into mass production

Which of the following will be the characteristic of the cars of 2030?

A. The car will speed up out of control.

B. We will own as many cars as we want.

C. Cars will produce more pollution than present ones.

D. All cars will be driven by computers.

The expression closest in meaning to the phrase “in convoy” in the last paragraph is________.

A. sidelong         B. in line    

C. side by side         D. shoulder to shoulder

What will happen if cars are joined to each other electronically in 2020?

A. There will be less pollution caused by car.

B. Motorists will get a clear view of the road.

C. The weather condition will not have effect On motorists.

D. All trains will burn less fuel than present.
