What must you 1when you receive a present for your birthday? You should sit down and write a thank-you letter. The sentence "Thank you." is very important. We use it often. We2when someone gives us a drink, helps us pick up things, hands us a letter, lends us a book, or gives us a present.

    3important word is "please". Many people always forget 4it. It is not polite to ask someone to do something5 saying "please". We use it when we 6 something too. It may be a book or a pencil, more rice or more tea. It may be used in the classroom, at home, at the bus stop or in a shop. We have to say "please" to make each other 7.

    We have to 8to say "sorry" too. When we hurt someone, we have to say we are9. When we tell a lie and feel sorry, we use10 word "sorry". When we forget something or break something, we use the word "sorry" too. "Sorry" is a word that can make people forgive mistakes.

    Tigers are very strong and scary. We may see tigers in Europe, Asia and America in the mountains. The tigers live far away from {#blank#}1{#/blank#} houses. They eat birds, hares (野兔) and other small {#blank#}2{#/blank#}. In the day they hide in the dens (巢穴), and at night they go out {#blank#}3{#/blank#} food.

    In {#blank#}4{#/blank#} when tigers are hungry, they will become very {#blank#}5{#/blank#} But now, people cut down many {#blank#}6{#/blank#}, so tigers are losing their homes. Also, some people kill tigers to get {#blank#}7{#/blank#} fur. Some people even buy things made {#blank#}8{#/blank#} tiger bones (虎骨). So the number of tigers {#blank#}9{#/blank#} getting smaller and smaller.

    Animals are our {#blank#}10{#/blank#} friends. In order to protect them, we must build many natural reserves. And we must stop people from hunting.

① A survey(调查) has shown that lots of people can't sleep well. Sometimes you feel tired when you wake up. You may have a headache and you feel like you could sleep for another three hours. Many things around us cause sleeplessness. Here are a few changes you can make to improve your sleep.

②Go to bed and get up at the same time. You may share the same bedroom with your sister or brother. You both must go to bed regularly(规律地) so that you don't trouble each other.

③Clean up your bedroom. A study from a university in Zhengzhou found that people with clean bedrooms usually sleep better than those with dirty and untidy rooms.

④ Get more house plants. Studies show that house plants help with reducing (减轻)stress. Also, plants such as lavender(薰衣草) and gardenias(栀子花) have smells that may help some people relax and sleep better.

⑤ Make your room dark. When light hits your eyes, it tell you not to fall asleep. In fact, we need darkness especially in the evening. So if you want your body to know that it's time to rest, turn off the lights about an hour before bedtime or wear eye masks. Your phone and your TV should also be thought of. You may also use the dark curtaıns(窗帘) to keep any outside light from going into your bedroom.

⑥Lower your bedroom temperature. The body becomes cooler at night, so lowering the temperature before bedtime can help you relax and fall asleep more quickly. The NationalSleep Foundation in a country says your bedroom should be about 16 ℃ to 19℃ for a good night's sleep.

Hi, everybody. Here we're in front of the South Gate. Go straight on, and you'll find the Panda House. Pandas are cute. They like to eat bamboo and lie down all day long. Every year, lots of visitors come here to see them. 

Walk along the road. To the north of the Panda House, you'll find the lions. Lions are the kings of the animal world. Remember that they're dangerous. Never go near them. 

Turn left, and to the west of the Lions' Area, you'll find the World of Birds. Birds make beautiful sounds when they sing. To the north of the World of Birds is the Monkeys' Forest. Monkeys are clever and funny. They jump around and make people laugh. 

Then turn right, and to the east of the Monkeys' Forest, you'll see the giraffes(长颈鹿). They're quite tall. Their long necks help them eat the leaves from trees. 

Northeast of the giraffes there's a bridge. Cross the bridge, and you'll see the elephants. Their large ears are like open fans. 

Here you can see all kinds of animals. Have a nice trip!

Hello, I'm Bob. I'm 12 years old. I am at school now. I want to say something about myself. 

Playing volleyball is my hobby. I like it very much. I always play volleyball with my friends after school. It's relaxing for me. I have five volleyballs. They are under my desk. And I like to watch volleyball games on TV. 

I have eggs, milk and some fruit for breakfast. For lunch, I have noodles and some salad(沙拉). For dinner, I like chicken and some vegetables. I don't eat ice cream. It's not healthy. My favourite food is fruit and vegetables. I think they are good for our health. 

I'm healthy because I like to play sports and eat healthy food. What about you? Can you tell me about your hobby and eating habits?
