1 . Most people are afraid of sharks，but they usually do not know very much about them.For example，there are 350 types of sharks，and all of them are meat eaters.Some sharks are very big.
The whale shark is 50 to 60 feet long.But some sharks are very small.The dwarf（侏儒）shark is only 6 inches（英寸）long.Sharks are 100 million years old.In fact，they lived at the same time as dinosaurs.Today，sharks live in every ocean on the earth，but most sharks live in warm water.They keep the oceans clean because they eat sick fish and animals.Most sharks have four to six rows of teeth.When a shark's tooth falls out，another tooth moves in from behind.Sharks do not have ears.
However，they "hear" sounds and movements in the water. Any sound or movement makes the water vibrate. This helps sharks find food. Sharks use their large eyes to find food，too. Most sharks see best in low light. They often hunt for food at dawn（黄昏），in the evening，or in the middle of the night. Scientists want to learn more about sharks for several reasons. For example，cancer（癌症）is common in many animals，including people. However，it is rare（罕见的）in sharks. Scientists want to find out why sharks almost never get cancer. Maybe this information can help people prevent cancer，too.

If you follow these steps below, you'll know what is worth seeing and doing, so that you can make the most of your time at the museum.
Decide what museum you will visit. There are so many different kinds of museums and you first need to find one that you like. It's easy for you to choose one and start an enjoyable visit!
Do some research online. Every museum now has a website which allows you to look through the information about it. On the website, you may look for such things as:
The exhibits. See what is on show at the museum at all times, and what special exhibitions are held for a short time.The history of the museum—There will often be very interesting stories about the exhibits and the benefactors(捐赠者). That can make your visit more interesting.Activities—See whether there are talks, tours or special activities on the day when you visit. Many museums hold some activities that meet the interests of all age groups.Cost, food and storage—It’s important to know how much the visit will cost. You hate to decide whether or not you can eat there. You might also need to find out about our transportation needs, as well as storage for coats, bags etc..Learn at least one thing on your visit. It’s always good to take away something new from your visit.
Plan breaks into your visit.When you walk around, standing here and studying exhibits there, you may become very tired. So it’s important to take breaks. A break is a good opportunity for you to think of what you have seen and what else you might want to do in the museum.
Take a friend or two. Visiting museums is always a lot more fun when you are with someone else. You can talk over what you’re seeing. A friend also brings another way of thinking when you talk about the exhibits.

The study involved fruit flies(g果蝇), as they share many genes(基因) with humans. Researchers gave one group of fruit flies normal food, and another group of fruit flies got the same food including apple.
The results showed that flies that ate apple lived an average of 55 days longer than the flies that didn’t eat apple. The study also found that apple-eating flies were more able to walk, climb and move about as they became old, the Journal of Agricultural and Food Chemistry reports.
The researchers believe that the antioxidants (抗氧化剂）found in apples are good for health.
In another experiment, researchers studied the diets of thousands of women. They found that those women who often ate apples were 20 percent less likely to have heart disease.
Scientists have recently discovered the apple’s genetic code(基因代码). This allows scientists to make new kinds of fruit that are healthier. Researchers are already using this information to grow apples with added antioxidants. Antioxidants help to keep eyes and joints (关节)healthy and protect against heart attacks and cancer.
Apples that help people lose weight may be in supermarkets in just four or five years. They are said to be “extra healthy” apples that can stop people from overeating.

Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they ran, too. They know there is danger. The rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of language. When a bee finds some food, it goes back to his home. It can’t tell the other bees where the food is by speaking to them, but it does dance in the air. This tells the bees where the food is.
But animals say things by making sounds. A dog barks, for examples, when a stranger comes near. A cat purrs(发出呼噜呼噜的声音) when pleased. Some birds make several different sounds, each with its own meaning.
But human beings have something that no animals have---- a large number of words about things, actions, feelings or ideas. We are able to give each other information to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animals can do this. No animals has the wonderful power of language.
No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.
People in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for examples, contains four or five hundred thousand words. But we don’t know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we met a new word, look it up in the dictionary. A dictionary is the most useful book.

8 . Many cultures have different ideas about why people catch colds. For example in the United States, some people think that you can catch a cold if your feet get cold. So, mothers tell small children to wear warm boots in the winter. In other places, including parts of the Middle East, some people believe that strong winds cause colds. So, on trains and buses, people usually don’t like to sit next to open windows. In parts of Europe, some people think that wearing wet clothes will give you a cold. They say that after you go swimming, you should quickly put on dry clothes. Today, scientists know that colds are caused by a virus (病毒).

9 . Do you carry too much on the way to school or home? Don’t worry. Try e-readers(电子阅读器)and say goodbye to your heavy schoolbag．
An e-reader has the memory space to hold hundreds of books. So people want to(A)扔掉沉书包and read with small, light e-readers. For example, Cushing Academy, a high school in Massachusetts, USA, replaced(替换)most of the 20,000 books in (B)its library last summer. Teachers and students will use e-readers instead.
Most e-readers are thin and weigh less than 500g. They can download(下载)an e-book in 60 seconds. “It’s (C) so easy. You can have a lot of books right at your fingers!” said Meghan Chensusky.
Chinese schoolchildren are also trying e-readers. At the Shanghai World Expo(世博会), an e-schoolbag is now on show. It is a special e-reader. Students can use it to download textbooks from the school servers(服务器). (D)It can also send and receive homework. Some Schools in Beijing and Shanghai have tried this e-schoolbag for a few years. “It’s excellent．I (E) don't have to carry a heavy schoolbag anymore,”said Xiao Qi, 15, Beijing.
New e-readers are not just for reading. They have Wi-Fi and multimedia(无线电视和多媒体)．Parents worry that these may hurt their children’s study habits. “I think Wi-Fi is not necessary for kids,”said Zeng Wenwen, 43, Beijing．
