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

void common words like ‘a’ or ‘the’ in a search. These aren’t always helpful and are usually unnecessary.

R

emove unwanted results by adding a minus symbol (-). For example, would leave out all references to hotels and films.

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(过滤程序). 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.

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(包围) 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(纳米机器人). These tiny robots move from cell(细胞) 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?

________________________________________________________________________

1.Microscopic robots. 2.Fighting disease or repairing the environment. 3.Because they are so tiny. 4.The ability to reproduce. 5.Whether we should research nanorobots or not. 6.Any reas...
