How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.
For some parents, the Internet can seem like a jungle (丛林), 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), the wilds of the Internet can be safely navigated . "Kids have to be on-line. If we tell our kids they can’t be allowed to surf the Internet, we are cutting them 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 would be to use what is known as a “content screener ". But this can’t be wholly reliable, 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 to do on the Internet. Another way is that Mum or Dad is nearby when the child is surfing the Internet.
A few other tips:
--- Don't put the PC in the 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 friend they make online,
--- 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.

Do you know mulch? Mulch is a protective cover of material that is spread on top of soil. It is usually made out of organic material, like crop waste. Farmers may keep the remains of corn or other crops on top of the soil. This creates mulch on the soil surface. The plant remains help protect the soil against wind and water damage. Mulching is one of the best things people can do for their plants. It also helps keep the soil from getting dry, and reduces the need for watering plants. It also limits temperature changes in the soil. And it stops unwanted plants, or weeds, from growing.
Organic mulch improves the condition of soil. As the mulch breaks down, it provides material which keeps the soil from getting hard. This improves the growth of roots and increases the movement of water through the soil. It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants. It also provides good environment for earthworms and other helpful living things in the soil.
It is easy to find organic mulch materials. Cut-up leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from news- papers works well in controlling weeds.
The best time to add mulch depends on your goal. Mulch provides a thick barrier between the soil and the air. This helps to reduce temperature changes in the soil. As a result, mulched soil will be cooler than other soil in the summer. In winter, the mulched soil may not freeze as deeply as other soil. The best time is after the ground has frozen, but before the coldest weather arrives. Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter. Delaying the spreading should prevent this problem. The animals will probably find another place to live.

Summer is the perfect time to relax. As you plan for your trip, here are some tips on how to protect yourself. 1.
Fight against the mosquitoes in the hot spots.
There are many mosquito-borne illnesses in tropical regions, which are traditionally vacation hot spots. Therefore, mosquito repellent（驱蚊剂）that contains DEET should be an essential item in your travel bag.

If you can't avoid unhealthful water, make sure you bring along a tea or coffee—making pot that will boil water for you.

4. They may have been washed in the same water, or wiped with the same rag used to clean work surfaces in kitchens. The best advice is to bring your own peeler（削皮器）so that you know that something clean has been applied to the fruit.
Enjoy the smell of roadside stands, not the food.
Unless the food is piping hot when served, it’s best to stay away from roadside stands, no matter how good the smell of the food might be. If you are concerned about whether a restaurant is clean, order the food to go. 5.

How to Protect Your Ears
You and your friends are leaving a concert on a Friday night. When you get outside, your ears are ringing. You have to shout to be heard.1. So no harm done…right?
Not quite. Temporary buzzing may be easy to ignore, but repeated exposure to loud noise will eventually cause serious--- and irreversible(无法治愈的)--- hearing loss. A new study conducted by researchers at Brigham and Women’s Hospital in Boston shows that one in five people between the ages of 12 and 19 are experiencing slight hearing loss, and one in 20 have mild hearing loss. 2.
But the good news is that there plenty of ways you can protect your ears from further damage — and still listen to the music you love:
Ask around. Put your earbuds in or your headphones on, and then ask a friend next to you whether or not he or she can hear what you’re listening to.3.Turn it down.
Buy noise-canceling headphones. A pair of earbuds or headphones that fits comfortably will limit outside noise so that you can hear your music better at lower volumes.
Take breaks. 4. So when listening to music, take your headphones off for 15 or 20 minutes and let your ears enjoy the quiet.
5.You can buy a cheap pair at any drugstore as an easy way to lower volume at concerts — or while playing or practicing your own music — without changing the quality of the sound.
A. Use earplugs.
B. Keep the volume below 70 percent.
C. If the answer is yes, your music is too loud.
D. Like every other part of your body, your ears need rest.
E. But by morning, your hearing is totally back to normal.
F. Unfortunately, there’s no way to get back hearing you’ve already lost.
G. The exposure to noise is louder and longer than in any previous generation.
