With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people, nature, and the environment.

Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.

Of all of today’s environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. There are, of course, long-term effects, but it is usually more serious in the short term.

Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened.

Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!

We should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on. Much of this research has, in the past, been held back by the oil, gas, and coal.

If the world’s millions of cars were 10% more efficient(高效的) — and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.

What is the passage mainly talking about?

A. Oil spills pollution. B. What oil pollution is.

C. Oil tanker accidents. D. How to reduce oil pollution.

How does the author support the idea that oil spills are not as serious as people believe?

A. By giving a description. B. By making an argument.

C. By giving an example. D. By drawing a diagram.

What does the underlined word “risk” in Paragraph 5 refer to?

A. Transportation depending more on oil. B. Poisonous oil breaking down naturally.

C. Millions of tons of oil spilling into the sea. D. More environmental damage being caused.

Which suggestion is made for reducing oil tank accidents according to the passage?

A. We should build safer oil tankers in the near future.

B. We should develop new technologies to cut oil use.

C. Tankers should not be allowed to sail near the coastlines.

D. Countries should build more oil pipelines under the sea.

Expert: Science Adviser - <>3/21/2011

QUESTION: Dear Marie,
Do you have some good suggestions of biology: plant, animal, human science experiments that would work well with teenagers? Scientific methods must go with the experiments. Thanks! <
Donna
ANSWER: Dear Donna,
Marie is not online and I’ll help you instead of him. There are a lot of little things that can be done, but do you mean lab experiment or statistical analysis, etc.? Let us know what can be suitable for you teens, and we will do our best to send you some experiments to do.
Best，
Gloria

Expert: Science Adviser - 3/23/2011

QUESTION: Dear Gloria,
I need lab experiments. The teenage students and I will use data from these experiments to make charts, graphs, tables, etc. and to provide claims and evidence to explain more about the results. Thank you very much.
Donna
ANSWER:
Hi there,
Your best and easiest way is to do some chemistry experiments. Those are very easy and most probably you can do it in the lab and have charts, etc. for you. I do not have any particular one at the top of my head because I do cancer research and it is a bit more difficult than research for teenagers. I think you can look through these and see if you find something useful for you. http://www.siraze.net/chemistry/sezennur/experiments.htm
If not, get back to me and Marie, and we’ll look more. The good thing about this site is that it has the procedures that you can follow.
Good luck，
Gloria

★The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana(大麻). Psychologists say that sending/receiving messages or looking through the many menu options your mobile phone has, lowers a person’s IQ by almost 10 points. British researchers have named this situation “infomania”. Instead of fixed on what they are doing, people’s minds are constantly focused on reacting to the technology surrounding them. This means they don’t pay full attention to the work they are paid to do. The report also added that the brain can not do so many things at once. If you try to do too many things, mistakes begin to occur. And while modern technology can have huge benefits, too much use can be damaging not only to a person’s mind, but to their social life.

★The more televisions 4-year-old children watch, the more likely they are to become bullies later on in school, a newest U.S. study said. At the same time, children whose parents read to them, take them on outings and just generally pay attention to them are less likely to become bullies, said the report from the University of Washington. Researchers also found gaps in learning and understanding such things as social skills early in life makes it more difficult for children to relate with other children. Watching violence on television leads to aggressive behavior.

★You could soon be able to add your favorite perfume to your e-mails. UK net provider Telewest Broadband is testing a system to let people send e-mails over the Internet with sweet smell. It has developed a kind of hi-tech air freshener that plugs into a PC and sprays a smell linked to the message. Telewest says it could be used by supermarkets to attract people with the smell of fresh bread or by holiday companies seeking to stir up images of sun-kissed beachers.
