(Here is a mom's letter to her son.)

Dear son,

    When I grow old one day, please{#blank#}1{#/blank#}me and try to understand me. Don't{#blank#}2{#/blank#}some of my behaviors(行为). If I make a(n){#blank#}3{#/blank#}when eating, please clean it up. If I can't dress myself, please help me. If I say something again and again, please listen to me. {#blank#}4{#/blank#}you were a kid, I read you the same story over and over again. If I can't walk, please{#blank#}5{#/blank#}me your hand. I did the same thing for you when you were learning to walk, When I am{#blank#}6{#/blank#}, you should look after me well. I can only {#blank#}7{#/blank#}you. I have no one else. I looked after you, so in the future it's{#blank#}8{#/blank#}that you look after me.

    I love you, son!

    Your mom, 

Linda Brown

    For example, people with type A blood are usually serious. They always have a{#blank#}1{#/blank#} and careful attitude when they deal with many things; People with type B blood are cheerful, and outgoing; People with type O blood are generous and honest; while those with type AB blood are often caring and helping. They are always willing to{#blank#}2{#/blank#} others.

    Last year, a doctor in the United States wrote a book that links blood types and what people eat. For example, his book gives some{#blank#}3{#/blank#}, like people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book, Eat Right for Your Type, has been a hit with people who want to lose weight. What's more, the book says eating food that{#blank#}4{#/blank#}a person's blood type can not only help them lose weight but also make them healthier.

A: Hey, Paul! Over here! Don't you remember me?

B: Oh, Tina! What a surprise to see you here!

A: That's right. I haven't seen you for {#blank#}1{#/blank#} two years. Where have you been these two years?

B: I have been on the city basketball team and have been busy {#blank#}2{#/blank#} I'm o on vacation here this week. What do you do now?

A: I am a {#blank#}3{#/blank#} in a band.

B: Really? You used to be {#blank#}4{#/blank#} in front of people, didn't you?

A: Yeah, but now I am very outgoing.

B: Wow! People surely change. How many members are there in your band?

A: There are four, three boys and one girl. We are going to give two {#blank#}5{#/blank#} at Screen City this Saturday. Would you like to come?

B: Sure, I'd like to.

What are computers?

    Computers are wonderful machines. They can store information and solve problems.

    Computers come in all sizes. Some are small enough to fit into our {#blank#}1{#/blank#}; others are so big that the can fill{#blank#}2{#/blank#}.

    Some people say that computers can think themselves. This is not true. Human beings give computers instructions and tell them{#blank#}3{#/blank#}.

    However, computers can do things better than people. They can store {#blank#}4{#/blank#}information and never forget it. They work out difficult problems very, very quickly-usually{#blank#}5{#/blank#}than any human being.

    You may have used computers such as a pocket calculator, {#blank#}6{#/blank#}or a personal computer. If not, why not learn{#blank#}7{#/blank#}right away？

There are many wetlands (湿地) in China ‒ and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are {#blank#}1{#/blank#} them. They are in Yancheng, Jiangsu Province. They are {#blank#}2{#/blank#} to many different kinds of animals. The world's {#blank#}3{#/blank#} Milu deer nature reserve (自然保护区) is on these wetlands. More than 700 Milu deer live there. There are not many red-crowned cranes (丹顶鹤) {#blank#}4{#/blank#} in the world, but every winter, you can see some in the red-crowned crane nature reserve in the Yellow Sea Wetlands.

    The {#blank#}5{#/blank#} in the wetlands is neither too high nor too low. There is  {#blank#}6{#/blank#} rain and sunshine, too. They are a good place for wildlife. But offering food and shelter for special kinds of animals is not the  {#blank#}7{#/blank#} reason we need to protect wetlands. Wetlands are important {#blank#}8{#/blank#} they also prevent floods. But some people want to {#blank#}9{#/blank#} the wetlands to make more space for farms and less space for wildlife.

    More people are beginning to realize the {#blank#}10{#/blank#} of wetlands and wildlife. Every year, on Feb 2, many activities are held to teach people about the wetlands.
