One morning, Lillian was sitting in the garden.

    She was looking at the wonderful 1 of every colour. Her favourites were the big yellow sunflowers. They had 2 yellow faces.

    She 3 that the sunflowers turned their big heads towards the sun as it rose in the east. "Wow! That's why people call them sunflowers," she thought.

    "Do sunflowers 4 LOVE the sun?" she wondered.

    At noon, Lillian looked at the sunflowers again. 5 !The sun moved across the sky. And all the sunflowers turned their heads to 6 it as it moved.

    That evening, 7 the sun was setting(下山)，Lillian noticed that the sunflowers were all facing west- 8 the setting sun. Their faces turned again!

    "Sunflowers really do love the sun," she thought to 9 . "They follow it across the sky each day, turning their faces to 10 as much sun as they can."

    The sunflower-what an interesting name and plant!

    For the first time. scientist have made clones(克隆) of monkeys. A clone is a copy of a living thing. A team of Chinese 1used cloning to make two baby monkeys. Both are girls. They are named ZhongZhong and Huahua.

    Scientist have cloned other kinds of 2. They have cloned dogs and cats, they have also cloned pigs, cows and ponies. The 3animals to be cloned in the world was a sheep named Dolly. She 4in 1966.

    Scientist had never been able to clone primates (灵长类动物), Primates are a group of animals. They include monkeys. apes (猿) and people. Now, that has come true. Soon scientist may be able to clone 5 too. However, the Chinese scientist will not be cloning people, they will keep cloning monkeys6monkeys are more like people than other lab animals such as mice or rats. Lab animals can help to study diseases. Cloning monkeys is 7to the scientist for medical studies.

    However, there are still reasons that some scientists want to8people. For example, some parents might want to clone a child who has died. Yet the cloned Child would 9really be the same. They would look like the same, but would not be the same one. It might be hard for them to know that they were a clone of10else.

    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.

    Hi, friends!1 me! I2Africa. And now I live in a zoo in the south of China. People always3 that animals are their friends, but they don't treat (对待) us as true friends.

    Every day, many people come here to4me. It seems (看起来) that I can make them very happy. But I don't like to live here,5I don't have many friends. And people think sometimes I am dangerous, so I have to be in the same6all day. It's boring for me. And in my hometown (家乡), people7many of my friends for their ivory. They are in great8. I don't want to live here. I want to go back to nature (大自然) and9 a happy life. Do you know who I am? I'm a(n)10.

    Please come and save us.

    Sam Scott and his sister are both students. They1to school every day. Some students often take a bus to school. They sometimes play2after school. They do3homework before dinner. They watch TV4about an hour. They go to bed5 It's a good habit.

Early to bed and early to rise makes a man healthy, wealthy (富有) and wise (聪明). This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.

Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you go to bed late, you can't have enough sleep. Then you can't think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!

Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak.

Exercise keeps it strong. Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!

Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.
