【題目】【改編】Robots industry is developing so rapidly that there is no denying that we may one day find ourselves surrounded by robots.

The humanoid (human like) robots with two legs such as Honda Motor Co. Ltd’s ASIMO would likely have an easier time climbing up stairs inside homes than a robot that moves on wheels, developers say.

But it will be some time before such devices make their way into people’s homes.

“They may look smart, but they are still quite stupid,” Shimoyama said. “I don’t think they will ever be as smart as humans.”

While safety is an obvious concern, robots also need to be sensitive to people’s needs.

Researchers at Fujitsu Frontech Ltd and Fujitsu Laboratories responsible for developing “Enon”, a guide and patrol (巡邏) robot designed for use in shopping malls and corporate facilities (公共場(chǎng)所), are working on this.

Enon, which has a humanoid upper body but no legs, is equipped with a touch screen on its chest and space in its stomach to carry loads weighting up to 10 kg.

In guide mode, it will check a newcomer and approach the person with a nod and a greeting: “Are you a visitor? Hello.”

Visitors requiring directions can point to icons (圖標(biāo)) displayed on Enon’s chest screen. If the restroom icon is pressed, the screen will display a map that shows the way.

The robot will then face and point in the direction of the restroom, although it won’t actually walk the visitor there.

Enon is now in use at four locations in Japan, including a shopping mall near Tokyo. The main goal is to make it more helpful for the elderly.

“People who work in the transportation sector often ask whether we can build a robot that will find elderly people who look lost in train stations, and ask them if they are all right,” said Toshihido Marita, director of Fujitsu Laboratories Ltd’s autonomous system laboratory. “Actually that is hard to do, very hard,” he said.

【1】From the passage we can know____.

A. robots will replace human one day

B. robots are difficult to control

C. robots can do whatever humans do

D. robots will be widely used in our life.

【2】According to Shimoyama, robots are ____?

【3】What can “Enon” do?

A. Show you to the toilet.

B. Show you around the market.

C. Tell newcomers or tourists direction.

D. Help shop assistants.

【4】What is the people’s concern about robots?

A. Safety. B. Appearance.

C. Weight. D. Disadvantages

【5】What can be the best title of the passage?

A. The disadvantages of robots.

B. The development and use of robots.

【題目】閱讀下面的短文，然后按照要求寫(xiě)一篇150詞左右的英語(yǔ)短文。

Almost every family buys at least one copy of a newspaper every day. Some people subscribe to as many as two or three different newspapers. But why do people read newspapers?

Five hundred years ago, news of important happenings — battles lost and won, kings or rulers overthrown or killed — took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in faraway countries on the same day they happen.

Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and of course, advertisements. There are all sorts of advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.

Newspapers often have information on gardening, cookery and fashion, as well as a small but very popular section on jokes and cartoons.
