    Joe，75，lived very happily and had a beautiful family．He had four grandchildren，and they all visited him in their holidays.

    But while he was working，he lost his favorite watch．Before they came to visit，Joe was getting ready for his home for the kids：cleaning the house, buying their favorite foods and cooking delicious food..．

    The watch was a gift from his deceased(已故的)wife when their first child was born．Joe loved the watch very much．He was very unhappy．

    When his grandchildren came，they promised him they would find the watch．

    One granddaughter asked：“Grandpa，do you remember when you lost your watch?

    Joe answered：“I guess when l cleaned the barn!”

    The children looked for more than two hours but could not find it．

    One grandson went to search(搜寻) the barn again，and Joe asked why he was going there．The little boy asked the others not to follow him and to keep silent(安静的)．

    He was there for about 15 minutes and then ran to his grandfather．He found the watch!

    Joe was surprised and asked how he was able to find it．The little boy said：“I sat there without making a noise，and the barn was so silent．After a few minutes，I heard the ‘tick，tick' sound and found the watch．”

    Joe hugged him and thanked the little boy．

Hello, everyone!My name is Liu Wei. I am 12 years old. I was born in Nanjing. I am a friendly and honest boy. I have a happy family. There are four people in my family—my father, my mother, my sister and me. 

My father looks strong. He is a doctor in a hospital near my home. He is so busy that he has no time to play with me. But I know he loves me. He likes running, swimming and playing basketball. 

My mother is tall and slim. Her hair is long and black. She has many hobbies. She is good at planting vegetables and flowers. She also enjoys traveling with me. My mother does a lot for me. She always looks after me well. And she is very strict(严格的)about my study. 

My sister is 13 years old. Her name is Liu Li. She has big eyes. She looks cute. In her free time, she likes reading, dancing and listening to music. We study in the same school. She is good at all her lessons. She wants to be a Chinese teacher when she grows up. 

I love my family very much. I hope all my family members always stay happy and healthy. 

Sam is an eight-year-old student. He can't always have fun at school,1 he doesn't like his school. He is good at all his2 , but he doesn't have friends. Sam is not happy about that.3 a Saturday morning, Sam sees a big tree. 

A small blackboard is in 4 tree. It says, "I am a magic(有魔力的)tree. Say the right words to me and then I can 5 you."

Sam says many words but they are not useful. The tree6 say a word. At last, he says, "Please, dear tree! Thank you!" The tree says, "Sam，say7 more(更多) and then you can be happy."

After that, Sam often 8 "Please" and "Thank you" at school. His classmates think he is nice and they all want 9 his friends. Then Sam asks many of his classmates to come to his 10 birthday party. They all have a good time.

 An aquanaut(潜水员) called Fabien Cousteau drew many people's eyes. He helps to build the world's {#blank#}1{#/blank#}(large) underwater research(研究) station. He wants the building {#blank#}2{#/blank#}(be) an underwater form of the international Space Station (ISS). And it can be used by astronauts from different countries. It's not {#blank#}3{#/blank#} easy thing to do, but the idea receives much support(支持).

 The station, named Proteus, will be at the bottom(底部) of the sea. It will be a place for{#blank#}4{#/blank#}(scientist) to study the ocean.

 Inside the station, there will be bedrooms, laboratories, medical facilities(设施) and the{#blank#}5{#/blank#}(one) underwater greenhouse for growing food. Cousteau says that it will {#blank#}6{#/blank#}(take) three years to build.

{#blank#}7{#/blank#} he is short of money to develop the project, he is trying to raise money.

 Cousteau says that underwater research is even {#blank#}8{#/blank#}(important) than doing research in space, So far, people have known only about one fifth of the ocean floor {#blank#}9{#/blank#}(clear). There are still many possible things waiting {#blank#}10{#/blank#} people to find out. So Cousteau hopes the base will lead to many exciting discoveries.
