Some students from Thailand write an article on the website(网页). They ask us to save the elephants in Thailand. They tell us that the elephant is one of Thailand's symbols. Their first flag had a white elephant on it. This is a symbol of good 1.

    Elephants are 2 animals. They can play soccer or music. They can also draw very 3. People say that “ An elephant never forgets.” Elephants can walk for a long time and 4 get lost. They can also remember places 5 food and water. This helps 6 to live.

    But elephants are in great danger. Elephants are losing their homes 7 people cut down many trees. People also kill elephants for their ivory. Today there 8 only about 3,000 elephants (over 100,000 before). We must save the trees and not buy things made of ivory. Don't forget that Thai Elephant Day is 9 March 13^th . Let's work together and 10 the elephants!

    The lion is one of the most fierce (凶猛的) animals in the world. Lions can be1 in Africa and India. Lions in Africa can live without water for about one month. Lions are also popular animals in the2 . Almost every zoo around the world has a few lions. It is very3 for people to tell male and female lions from each other. You can judge (判断) simply by their appearance. A male lion has mane while female lions do not have. Male lions are 4than female lions. A male lion usually weighs about 200 kilograms which is always heavier than a female lion. Both male and female lions have very 5 teeth. They can break the backs of other animals 6 Lions feed on other animals and one lion usually kills between ten and twenty large animals each year for 7it's unusual for lions to kill people. However, in 1898 two lions 8and ate over one hundred people in Kenya before they were shot by a British man named Patterson. This 9 became the subject(主题) of a 1996 Hollywood movie called The Ghost and the Darkness. Now the Indian lions are endangered. It's really necessary for us to 10 the animals, or we won't see them again. Animals are our friends. It is our obligation to protect them.

    In some science fiction films, people in the future have their own robots. These robots are just like humans. They help with the housework and do the most1 jobs.

    Some scientists believe that there will be such robots in the future. However, they agree it may take hundreds of years, Scientists are now trying to make robots look like people and2 the same things as us. Japanese companies have already made robots walk and dance. This kind of robot will also be fun to watch.

    But robot scientist James White disagrees. He thinks that it will be3 for a robot to do the same things as a person. For example, it's easy for a child to4and know where he or she is. Mr White thinks that robots won't be able to do this. But other scientists disagree. They think that robots will be able to talk to people.525 to 50 years.

    Robot scientists are not just trying to make robots look like people. For example, there are already robots 6 in factories. These robots look more like huge arms. They do simple jobs over and over again. People don't like to do such jobs and will get bored, But robots will7 get bored.

    In the future, there will be more robots everywhere, and humans will have8 work to do. New robots will have many different9. Some will look like humans, and others might look like10 ， After an earthquake, a snake robot can help look for people under buildings. That may not seem possible now, but computers, space rockets and even electric toothbrushes seemed impossible a hundred years ago. We never know what will happen in the future!

    Hello, human friends. My name is Nick. I am a turtle (海龟). I have lived in the 1 for over half a century. In general, turtles can 2 to be more than 100 years old. 3many of my friends are now dying from one thing: plastic(塑料).

    Human beings use too 4 plastic. When you throw plastic away, it doesn't just disappear. Over 90 percent of the world's plastic doesn't get recycled(回收). A lot of plastic 5in the ocean. Most of my friends do not know the danger of plastic. They think it is 6. But in fact, plastic is 7. Around 30 percent of my friends have plastic in their body. I have plastic in my body, too. Plastic is also 8 other sea animals. Last month, one of my friends died after eating 80 plastic bags. I feel so 9 about it.

    My human friends, please 10 using too much plastic. Maybe one plastic bag or one coffee cup won't make a difference. But when seven billion people all start to use less plastic, it will make a big difference.

The first astronauts

    Since the earliest times, people have looked up at the stars, the moon and the planets. Today people use modern machines 1at the sky. This is very different from the situation2years ago when people could only use their eyes. Perhaps they dreamed of3the universe.

    When did humans first go into space? The story began not so very long ago, 4the first astronauts were not people-they were animals.

Scientists wanted to make travelling to space as 5 as possible for humans. So they decided to experiment with animals and test6 in spaceflights. Insects, mice, frogs, dogs and monkeys were some of the animals7first went into space. Many of them 8, but they helped to make space travel safer for humans. For their great service, we 9forget these animals.

    Albert Ⅱ was the first monkey to go into space in 1949. Sadly he died 10 his spaceship landed back on Earth.

    11 the result was different for Ham the Monkey. His story ended happily when he return to earth12very good health.

Scientists wanted to know the answer to the important question: could 13 animal like Ham do the same things in space as he could do on Earth? The answer came when Ham 14 into space in 1961. Yes, he did everything well and lived for 15 16 years

    There are many kinds of pollution around us, 1 air pollution, soil pollution, noise pollution and light pollution. They are bad 2 our health in many ways.

    Burning gas, oil and coal creates air pollution. It can cause some eye and breathing problems.

    With the 3 of pollution and the development of industry, litter is everywhere. It makes our environment dirty. People put lots of rubbish in the land. Farmers use too many 4 in the fields. They destroy the soil.

So soil pollution has become serious.

    Noise pollution can make people 5. For example, people may lose their hearing if they have worked in a 6 place for a long time. Too much noise can cause high blood pressure 7.

    Having worked for a long time in strong, changeable light 8 cause some kinds of illnesses. It makes people feel 9 and is especially bad for the eyes.

    With 10 pollution, our planet will become greener and our health will be better. Let's be greener people.
