Humans' Greatest Achievements

    I have a pet. His name is Lucky. {#blank#}1{#/blank#} My parents love him too. He is also one of our family members.

    When he was a small dog, he was very shy and he seldom barked. {#blank#}2{#/blank#} Maybe the dog just wanted to play with him, but he stayed behind me and looked at me sadly. {#blank#}3{#/blank#}

    However, my little dog barked loudly when there was a fire in the kitchen. I was very curious at that time why he became so excited and ran around me all the time. {#blank#}4{#/blank#}

    There is an old saying about pets in my hometown: to love your pet is to love yourself. I can't agree with it more. {#blank#}5{#/blank#} When we stay together, we enjoy ourselves very much. Life is just like this: we need a friend with us till the end.

    Much meaning can be carried clearly with our eyes，so it is often said that eyes can speak. Do you have such kind of experience? On a bus you may look at a stranger, but not too long. And if he finds that he is being looked at, he may feel uncomfortable. It's the same in daily life. If you are looked at for more than necessary, you will look yourself up and down, to see if there is something wrong with you. If nothing goes wrong, you will feel angry toward the person who is looking at you that way. Eyes do speak, right?

    Looking too long at someone may seem to be impolite. But sometimes things are different. If a man looks at a woman for more than 10 seconds, it may mean that he wishes to attract her attention, and to make her understand that he loves her. When two people are in a conversation, the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what he or she is saying. Lovers will enjoy looking at each other or being looked at for a long time, to show something that words cannot express.

    Clearly，eye contact(接触)should be done according to the relationship between two people and the place where you stay.

    Almost everyone likes apple pies in the USA. An apple pie is easy to make, so many people make it at home. You just need apples, flour (面粉), sugar, butter and spices(调味品).

    To make an apple pie, first peel and cut the apples into pieces. Then mix them with spices and put them in a pie tin (罐). Next put butter, sugar and flour in. Put the mixture on the apple pieces and bake the pie for about 30 minutes. The smell of the apple pie is great.

    There are many different ways to make apple pies. Some families have their own secret (秘密) ways and don't tell other people about them. Pies made with berries( 浆果) are also very popular in America. But the apple pie perhaps (也许) is the dessert that everyone loves best.

    {#blank#}1{#/blank#}We may feel excited when we have success in a school play. We may feel sorry if we lose an important game. We want to keep the memory for the rest of our lives.

    {#blank#}2{#/blank#}Our English teacher, Miss Wang, has taught us a good way of remembering things to make our own yearbook.{#blank#}3{#/blank#}A yearbook is a kind of book which is used to keep the memory of exciting moments.  It's usually made at the end of the year.

    {#blank#}4{#/blank#}First we chose the persons who had done something special, and then some students interviewed them, some wrote down their stories, and others took photos of them.{#blank#}5{#/blank#}Finally our teacher helped us to put these things together. We had our first yearbook.

    Every month, junior high schools in China choose one hero of the month. This person is a hero because he or she has done something to help protect animals in danger. Huang Jing decided to write a letter to the President of China.

Dear Mr President.

    I have been doing a project at school recently about animals in danger. I think the situation all over the world is really terrible. I am writing to you to suggest what China should do to help protect animals more.

    I know that there are nearly 2, 000 nature reserves in China, which is good. I live in Beijing and there are about 30 reserves outside the city. We visited one of them last month to sec for ourselves.

    I feel so sorry for the giant panda. It's one of the most popular animals in the world and a real symbol of China. We learned that pandas mainly live on bamboo, and that a panda can eat half its body weight of bamboo in 24 hours！That's a lot of bamboo. I think we should try to do more to stop cutting down forests. Pandas are already a rare animal and it would be so sad if they became extinct(灭绝)forever.

    The other animal we should try to protect more is the Chinese alligator(场子努). These creatures live in some parts of eastern China. These beautiful animals live in freshwater rivers and lakes but the water in some places isn't clean enough for them to live in. It's really dirty in fact. The government should stop factories polluting the lakes and rivers.

    If we protect these beautiful animals in China, more foreigners may wish to visit China to see them. They could be an important tourist attraction. It would be good if more people came to visit our beautiful country, especially to see the quieter areas in the country. Now most visitors just see the cities.

    I hope you will encourage more people to think about such an important subject.

Sincerely yours,

Huang Jing
