People in southern China like famous and expensive dish—shark fin soup, but no scientific studies have shown that shark fins are good for health. So why do they eat them? Do they realize that they're killing a whole shark each time they enjoy a bowl of shark fin soup?

When people catch sharks, they cut off their fins and throw the shark back into the ocean. This is not only cruel, but also harmful to the environment. Without a fin, a shark can no longer swim and slowly dies. Sharks are at the top of the food chain in the ocean's ecosystem. If their numbers drop too low, it will bring danger to all ocean life. In fact, around 70 million sharks are caught and traded in this industry every year. The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years. Help save the sharks!

    There are world records at the Olympic Games. But what are the word records in animal kingdom?

    The largest and heaviest animal on earth is the blue whale. It weighs between 110 and 120 tons. Its heart is the size of a Mini Cooper, It's got the biggest mouth in the world as well. About 100 people can fit inside it. But it doesn't eat people! In fact, the biggest thing it can eat is the size of an apple.

The giraffe is smaller than the blue whale but it is also a record breaker. It's the tallest living land animal. It's got the longest neck-about 2 metres long, and it's got the longest legs-about 1.8 metres long. Drinking is difficult, but eating from the top of trees is easy! And its tongue is 50 c m long!

    The most dangerous animal in the world isn't a lion or a bear. It's an insect! The mosquitoes (蚊子) that carry malaria kill over 1 million people a year. After that, the most dangerous animal is the venomous snake. They kill 50,000 to 125,000 people a year.

    We use the Internet for many things: business, shopping, writing letters, talking to people, finding information and so on. In recent years, a new kind of English has grown on the Internet. There's no real word for it yet, so we'll call it e-talk.

    People don't like typing too much. To save time, they turn phrases into a few letters (called acronyms). Acronyms are often used in chat rooms(聊天室). Some of them are:

    BTW (by the way)                 BRB (be right back)

    LOL (laughing out loud)            IMO (in my opinion)

    People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:

    info (information)                  puter (computer)

    pic (picture)                       sec (second)

    We usually don't see people when we communicate(交流) on the Net, so people have new ways to show feelings. Most people use their keyboards to draw "feelings", such as:

:-) (happy)    ;-)  (joking)   :-(  (sad)       :-O  (surprised)

    These days, many forums (论坛) have picture feelings. For example:

    There are even whole new words, like "newbies"(someone who is new on a chat board or forum). When you write something bad about someone else, it's called "flaming" the person.

    It takes time for people to get used to(适应) e-talk. Also, different groups on the Net have their own special ways of communicating. Newbies sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.

    Have you ever dreamed about a trip to the space? Seeds (种子) of some vegetables and crops are a lot luckier than you, as they have travelled to space and back.

    China is among the three countries in the world that carry out agricultural research (农业研究) in space. The others are Russia and the US.

    Since 1987, China has sent about 1, 000 species of seeds into space.

    These include green peppers, tomatoes, cucumbers (黄瓜), carrots, lettuce and wheat. Even on China's first manned spacecraft Shenzhou—V, there were some seeds from Taiwan.

    "Conditions in outer space such as radiation (辐射) and low gravity can cause big changes in the seeds," said Chinese researcher Jin Xing.

    But not all seeds are better after going to space. After returning to the Earth, the best seeds are selected. These seeds produce (生产) much more and also grow faster than normal (正常的) seeds
