How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U.S.

For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions(预防措施), the wilds of the Internet can be safely navigated(航行). “Kids have to be on-line. If we tell our kids they can’t have access(机会) to the Internet, we’re cutting them off from their future,” said an expert.

Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener(过滤器)”. But this can’t be wholly reliable(可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing(浏览) the Internet.

A few other tips

●Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.

●Ask your child what he or she has been doing and about any friends they make on-line.

●Tell your child not to give on-line strangers personal information, especially like address and phone number.

●And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

Where is that noise coming from? Not sure? Try living with your eyes closed for a few years.

Blind people are better at locating sounds than people who can see, a new study says, without the benefits of vision the ears seem to work much better.

Previous studies have shown that blind people are better than others at reaching out and touching the sources of sounds that are close by. Researchers from the University of Montreal wanted to see if blind people were also better at locating sounds that are far away.

Twenty-three blind people participated in the study. All had been sightless for at least 20 years. Fourteen of them had lost their vision before age 11. the rest went blind after age 16. The experiment also included 10 people who could see but were wearing blind-folds.

In one task, volunteers had to pick the direction of a sound coming from about 3 meters away. When the sound was in front of them or slightly off center in front, both groups performed equally well.

When sounds came from the side or the back, however, the blind group performed much better than the blindfolded group. The participants who had been blind since childhood did slightly better than those who lost their sight later.

Recognizing the locations of distant sounds can be a matter of life-or-death for blind people, say the researchers. Crossing the street, for instance, is much harder when you can’t see the cars coming.

Still, the researchers were surprised by how well the blind participants did, especially those who went blind after age 16. In another experiment, the scientists also found that parts of the brain that normally deal with visual information became active in locating sound in the people who were blind by age 11. These brain parts didn’t show sound-location activity in the other group of blind people or in the sighted people. The scientists now want to learn more about the working of brains of “late-onset” blind people.

The recent study shows blind people are better at telling __________.

A. The sources of loud sounds.     B. the locations of distant sounds

C. the direction of sharp sounds    D. the distance of a sound in front of them

Which would be a proper title for the passage?

A. A Research on Blind People     B. Where is That Noise Coming from?

C. Hearing Better in the Dark      D. What If Living Without Your Eyes?

If people were asked to tell the direction of a sound from the side, who would perform best?

A. Those who are blind.              B. Those who have gone blind since children.

C. Those who went blind at age 16.     D. Those who are blindfolded.

Which of the following is true according to the passage?

A. Whether to be able to locate the sounds can be of vital importance for the blind.

B. All the volunteers in the experiment are sightless.

C. All the participants did equally well when picking sounds from whatever direction.

D. The later people become blind, the better they can perform in telling the direction of sounds.

What do we know about that parts of brain dealing with visual information are active in locating sounds?

A. This happens in almost all the testers.

B. This only occurs in the people who were blind after age 16.

C. It remains nothing new to the scientists any more.

D. It remains a mystery why it is so.

How to use speed reading to go through newspapers or magazines? You will not only save time, but also your focus will increase and you will have fun reading even the  uninteresting reports.

   This plays to the advantage of the tired reader who wants to stay current but has very little time to read. Often all you need to understand a news piece is the first paragraph. Here the reporter will tell you what’s happening, who it’s happening to and where it’s happening.

Sometimes you don’t even need to read the entire paragraph because the first sentence or the first couple of sentences give you all the information. If you still have more time you can move on to step two.   Read the last paragraph. Some news pieces are follow-ups of events that were earlier reported. In such a situation, the first paragraph may not give you all the information you need.    It’s usually in the last paragraph that the user is given the background information that leads to the story.

Read the “quotes” after you’ve read the first and last paragraphs and you still feel you need more information or have more time to play with, you can come into middle of the piece by reading the direct speech of the sources of the news item. In all forms of writing where quotations are used, the writer leads the reader into the quotes and then leads the reader out. This takes too much space and therefore, robs the reader out of some precious time.

    

A. Read the first paragraph.

B. But the last paragraph will do the job.

C. The first paragraph may be not important at all.

D. Otherwise, you can stop reading.

E. Here are three techniques you can use.

F. So glide directly to the quotation marks and read what’s within them.

G. If you follow these steps, it’s possible to get about 80 percent of a news piece.

What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster? Yes, there really is a job where you can get paid to taste ice-cream. Just ask John Harrison, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream — as well as for developing over 75 flavors (味道).

Some people think that it would be easy to do this job, after all, you just have to like ice cream, right? No — there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this “cool” field.

In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12℉. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup .”While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the color expected from that flavor?” Next it’s time to taste!

Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy — working at one cool job.

What is John Harrison’s job?

  A. An official.     B. An ice-cream taster.

  C. A chemist.   D. An ice-cream manufacturer.

According to John Harrison, to be qualified in the “cool field”, it is helpful to ______.  A. keep a diary of work   B. have a degree in related subjects

  C. have new ideas every day   D. find out new flavors each day

What does Harrison do first when testing ice cream?

  A. He stirs the ice cream.         B. He examines the color of the ice cream.

  C. He tastes the flavor of the ice cream. D. He lets the ice cream warm up.

Which of the following is probably the best title of the passage?

  A. Tasting with Eyes      B. Flavors of Ice Cream

  C. John Harrison’s Life   D. One Cool Job
