【題目】A Cloud of Hope and Danger

A small cloud floats through the air in a hospital operating room. In the room a patient, suffering from cancer, lies on a table. The cloud surrounds(包圍) the patient, covering her body and filling her lungs(肺). The cloud is not smoke or steam. It is made of millions of microscopic robots called nanorobots(納米機器人). These tiny robots move from cell(細胞) to cell in the patient’s body, destroying the cancer.

Fighting cancer with nanorobots is only an idea today, but scientists say that it could be possible in the future. Using nanorobots for good purposes such as fighting disease or repairing the environment may be the solution to many of today’s problems.

However, nanorobots could be a dangerous risk as well. Since nanorobots are so tiny, they will have to work in large teams of many thousands to many millions. For this reason, nanorobots will have to be programmed to build themselves. Scientists will not have the ability to build millions of nanorobots one by one.

This ability to reproduce is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nanorobots would be far worse than any disease. Some people think that if they get out of control, nanorobots could destroy the Earth.

What should be done? Should we continue researching nanorobots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.

【1】What is the cloud in the passage, smoke and steam or microscopic robots?

________________________________________________________________________

【2】What can be the good use of nanorobots for us?

________________________________________________________________________

【3】Why will nanarobots have to work in large teams?

【4】What makes it possible for nanorobots build themselves?

【5】Can you give the passage another title?

【6】Are you for or against using nanorobots in the future? Why?

【題目】

There is an old saying：one good turn deserves another. It means you do a helpful or kind act for someone who has done something good for you. Denson is a mechanic（機修工），but he lost his job a few months ago. He is kind and helpful, but always feared applying for a new job.

One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 a.m. and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre（輪胎）of his car. Obviously（很顯然）there was something wrong with the ear. Denson immediately went up to lend him a hand. When Denson finished working on the car, the old man asked him how much he should pay for the service. Denson said there was no need to pay him and he just helped someone in need, and he had to rush for an interview. Then the old man said,“Well, I could take you to the office for your interview. It’s the least I could do. Please, I insist.”Denson agreed.

On arrival, Denson found a long line of applicants（求職人）waiting to be interviewed. Denson still had some grease（油脂）on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer’s office with disappointed looks on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked,“Do you really need to be interviewed?”Denson’s heart sank.“With the way I look now, how could I possibly pass this interview?”he thought to himself. Then the interviewer turned the chair and to Denson’s surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.“Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as a member of the company before you even stepped into the office. I just know you’d be a trustworthy（值得信賴的）worker. Congratulations!”Denson sat down and they shared a cup of coffee as he landed himself a new job.
