【題目】

Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet's health and people's health may be suffering from it.

The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes cleaner, sometimes not.”

It is not tested that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content(礦物質(zhì)含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn't have fluoride(氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that's behind the recent rise in bad teeth.

Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals into the water. Store bottled water appropriately. Bottled water, like many foods and drinks, should be stored in the appropriate way to keep the quality and safety of the product. Keep bottled water out of the light and heat.

According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.

For energy use, plastic bottles are also not cheap. One report said that if water and drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.

So, if you are worried about the effect of bottled water on the earth, you can take the following four steps:

Step 1. Drink from your tap. Unless your government warns against this, it should be fine.

Step 2. Get a container(容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.

Step 3. Keep it cool. Don't drink from a bottle that has been sitting in the sun, don't store it near chemicals, and don't reuse plastic bottles.

Step 4. Choose glass containers over plastic if possible. When finished, recycle!

A. Plastic bottles are not expensive to make.

B. It is tested that bottled water have high fluoride.

C. Bottled water may cause the rise in bad teeth.

A. we can do something to reduce the bad effect of bottled water

B. we can improve the bottled water by storing it in right places

Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 kinds of sharks, whose size, behavior, and other characteristics differ widely.

Every year, people catch and kill over 100 million sharks. They hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable. Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins.

It takes most kinds of sharks10 to 15 years to begin reproducing (繁殖)and most sharks reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is the special danger to the future of the animal.

Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea mammals, just like sea lions，sea dogs and dolphins. They sometimes mistake human swimmers for their food, especially if they are wearing black wet suits.

If you are a typical ocean-goer, your chances of being killed by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car.

According to the studies, most sharks can live 20 to 30 years. Although sharks cannot live as long as human beings, they have the similar aging process. Sharks help save human lives. They are helping us learn how to fight cancer and other diseases. Their highly effective immune(免疫的) system allows wounds to get better and their blood is being studied in connection with AIDS research.

Sharks are needed in the world’s ocean ecosystems(生態(tài)系統(tǒng)). Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

▲【2】 Break the ice by telling your pen pal a little about yourself. Start with your name, age and job. Write about what you like to do or what’s on your mind that day. What you pass on will encourage your pen pal to tell you something about his. 【3】

▲Ask questions. 【4】 This will help you get to know him and probably get you a faster answer. Make your questions into the e-mail by telling him something you like to do and then asking if he’s ever tried it.
