【題目】How to be a safe and smart SEARCHER

S

everal keywords will help to find better results. Use more than one keyword when you are doing a search. If you want to find out about seagulls, for example, search for and not just ‘seagull’ – because seagull might also be the name of just about anything else, from a hotel to a documentary film.

E

xact references can help you find what you’re looking for. If you are looking for an exact phrase or sentence, e.g. , type it between quotation marks (“”) and only exact matches will be shown. This is useful when you want to find something you’ve already seen but lost.

A

R

91 . Make sure that you spell every word in the search box correctly. The smallest typing mistakes can bring unwanted results - especially when the mistyped word exists.

H

ave a filter(過濾程序). It’s a good idea to filter your searches, especially when you are searching for pictures. Ask an adult to help you add a filtering system. There are lots of filtering software options available.

E

xperiment with different search engines until you find the one that’s best for you. Some search engines personalise the results. So check out the option of using a search engine that doesn’t do this and you will get different results.

R

eliability is very important when you are searching on the Internet. Always ask yourself, “Is this reliable?” Don’t make the mistake of believing everything you see. Some websites are unreliable and some information is false. Check your information on other websites before accepting it.

【題目】

Donna Reid had just finished her training as a children’s doctor. A famous research hospital in New York had offered her a job with good pay. And her boyfriend, Tony, had a clinic in their hometown and hoped she could work with him. At the same time, a small hospital, Backwoods Hospital, in a very poor area had also offered Donna a position. Now it was time for her to decide where to work.

Dad: Donna, that research hospital in New York has a good reputation for children’s medicine. Some of the best children’s doctors in the country work there and you can learn a lot from them.

Mom: Yes, I agree it’s a good hospital and the pay is good, too. But, that’s not the point.

Dad: Then what’s the point?

Mom: It’s in New York, too far away! Let me tell you what, dear Donna. Tony’s clinic is just several blocks away. You don’t need to travel far if you work there. Tony is a nice young man and I guess you’ll get married soon.

Dad: Ha! It’s hard enough to live with a husband or wife. Working with them, too? That’s a choice for trouble. Well, Donna, what do you think?

Donna: I’m thinking about accepting the offer from Backwoods Hospital.

Dad: But Donna, look at their offer! You’ll be on call six days a week, 24 hours a day. That’s really a hard job.

Mom: Oh, Donna, the pay is another problem.

【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(). 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.

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

________________________________________________________________________

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

________________________________________________________________________

3Why will nanarobots have to work in large teams?

________________________________________________________________________

4What makes it possible for nanorobots build themselves?

________________________________________________________________________

5Can you give the passage another title?

________________________________________________________________________

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

________________________________________________________________________
