uChildren start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’ve finished with your lists, do you have questions of your own about science?”

After a long pause, a boy raised his hand,” Have you ever seen a grasshopper（蚱蜢） eat? When I try eating leaves like that, I get a stomachache. Why?”

This began a set of questions that lasted nearly two hours. 

Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical（符合逻辑的）,complete and creative answers. 

Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas. 

Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement. 

Lastly, show doesn’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass（放大镜）, and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates （蒸发）,set a pot of water to boil and let them watch the water level drop.

Someday a stranger will read your email without your permission or scan the website you have visited. Or perhaps someone will casually glance through your credit card purchases or cell bills to find out your shopping preferences or calling habits.

? In fact, it is likely that some of these things have already happened to you. Who would watch you without permission? It might be a girlfriend, a marketing company, a boss or a criminal. Whoever it is, they will see you in a way you never intended to be seen-----the 21st century is the equal of being caught naked.

? Psychologists tell us boundaries are healthy and that it is important to reveal yourself to friends, families and lovers at appropriate time and places. But now few boundaries remain. The information you leave everywhere makes it easy for strangers to reconstruct who you are, where you are and what you like. Believe it or not, we live in a world where you simply can’t keep a secret. The key question is: does that matter?

? When you ask Americans about privacy, most say they are concerned about losing it.

? But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that can track automobile movements. And few refuse to offer personal information like Social Security numbers to get supermarket loyalty cards.

? But privacy (隐私) does matter—at least sometimes. It is like health: when you have it, you don’t notice it. Only when it is gone do you wish you had done more to protect it.

A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. All computer viruses are manmade. Here are some virus prevention tips.

Do not open any files attached to an e-mail from an unknown, suspicious or untrustworthy source.

Do not open any files attached to an e-mail unless you know what it is, even if it appears to come from a dear friend or someone you know. Some viruses can replicate（复制） themselves and spread through e-mail. Better be safe that sorry and confirm that they really sent it .

Do not open any files attached to an e-mail if the subject line is questionable or unexpected. If the need to do so is there always save the file to your hard drive before doing so.

Delete chain e-mails and junk e-mail. Do not forward（转寄） or reply to any of them. These types of e-mail are considered spam（垃圾邮件）, which contains lots of annoying advertisements and useless information.

Do not download any files from strangers.

Be careful when downloading files from the Internet. Ensure that the source is a legitimate（合法的）and reputable one. Verify（证实）that an anti-virus program checks the files on the download site. If you are uncertain, don’t download the file at all or download the file to a floppy（软盘）and test it with your own anti-virus software.

Update your anti-virus software regularly. Over 500 viruses are discovered each month, so you’ll want to be protected. These updates should be at least the products virus signature files. You may also need to update the product’s scanning engine as well.

   Back up（备份） your files on a regular basis. If a virus destroys your files, at least you can replace them with your backup copy. You should store your backup copy in a separate location from your work files, one that is preferably not on your computer.

Many children use the Internet to get useful knowledge and information, and to relax in their free time. But some of them are not using it in a good way. Here are some rules to make sure you are safe and have fun on the Internet.
※Make rules for Internet use with your parents. For example, when you can go online, for how long and what activities you can do online.

【小题1】The writer tells children to _________.

Someday a stranger will read your e-mail without your permission or scan the websites you’ve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.

In fact, it’s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend（配偶）, a marketing company, a boss, a cop or a criminal, Whoever it is, they will see you in a way you never intended to be seen -- the 21st century equivalent of being caught naked.

Psychologists tell us boundaries are healthy, that it’s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs （面包屑）you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal（泄露）what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.

The key question is: Does that matter?

For many Americans, the answer apparently is "no."

When opinion polls ask Americans about privacy, most say they are concerned about losing it A survey found an overwhelming pessimism（悲观）about privacy, with 60 percent of respondents saying they feel their privacy is "slipping away, and that bothers me."

But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths （收费处）to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠券).

But privacy does matter -- at least sometimes. It’s like health: When you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.
