Sam was very nervous. It was his firstday in a new1, and lunch was only thirty minutesaway. For most students, lunch is the 2 partof the school day. It is time when you talk with your friends, get to know whatinteresting things everyone is doing, and, of course, 3. Sam, however, didn't know anyone or anything,like where to sit or with whom to sit at lunch.

Sam's 4 wasin the army, so his family moved a lot. He had really liked his old school and 5 leaving his two best friends. They still talkedto each other through phone calls and emails, 6 he couldn't see them every day. He wondered iftheir 7 would continue. He didn't want to lose them, buthe knew it would be8 for them to stay close.

"I know this is hard for you,"his mother said as he got ready for school this morning, "and I'm really 9 youhave to keep changing schools. "Sam could see regret in her eyes, but hedidn't want her to feel that way. 10 had always been ready to defend (保卫) not only the family but also the country. Sam loved her so much. Hegave her a smile and told her not to 11 He had wanted to mean it, but there was stillalways worry in him when they moved.

The 12 timecame quickly. As Sam was walking to the dining room, a voice behind him said."Excuse me. "Sam 13 andsaw five friendly faces.

"Would you like to join us?"askedone of them.

This 14invitation was exactly what he needed. Samnodded yes 15 and joined them. He was sure about his futureschool life now.

It was about two o'clock in the early morning {#blank#}1{#/blank#} 21 September, 1999. Tommy was sleeping when the earthquake started. He felt a slight shake, then he {#blank#}2{#/blank#} a loud noise like thunder. Soon the real noise came, like bombs under the ground. The earth started to {#blank#}3{#/blank#} . People screamed in fear. Some ran out of the building. He tried his {#blank#}4{#/blank#} to run out too, but he couldn't.

Outside, people were running in all directions while pieces of glass and bricks were falling down. Then the {#blank#}5{#/blank#} began to come down too!

Finally, the noise and shaking ended. It was dark and silent around him. He could not see anything at all, and he did not know if anyone else was near him. He felt {#blank#}6{#/blank#} and his heart was beating fast. A moment of fear went through his mind, but he told {#blank#}7{#/blank#} to calm down since he was still alive. He shouted for {#blank#}8{#/blank#} , but no one came. He started to move slowly in the darkness. Luckily, there was just enough space for him to move.

Hours later, Tommy heard {#blank#}9{#/blank#} noise above him. He screamed, "Help! Please help! I'm here!" Then he heard shouts from excited people. They {#blank#}10{#/blank#} moved away the bricks. At last, Tommy was safe.

Jack and Emily are good friends. Emily loves {#blank#}1{#/blank#} (植物) , and Jack is {#blank#}2{#/blank#} (感兴趣的) in animals. They like to go {#blank#}3{#/blank#}(户外) to have fun. They live {#blank#}4{#/blank#} from (在.......对面) a park, and it is a great place for them to find {#blank#}5{#/blank#}(某物) interesting. They often watch birds, take photos, and {#blank#}6{#/blank#}(收集) flowers and {#blank#}7{#/blank#}(昆虫). And they dream to be {#blank#}8{#/blank#} (科学家) in the future. It's exciting to {#blank#}9{#/blank#} (开启) their own projects and {#blank#}10{#/blank#} (发现) the beauty of nature together. 

 Lychee(荔枝) is a kind of delicious fruit. It comes from warm and wet places in southern China. The sound of the word"lychee" comes from its Chinese name. Lots of people love eating it because it's delicious and full of vitamins(维生素). It can help people keep healthy and strong. However, ▲. Low temperature lychee preservation(保存) technology can help to solve the problem. Zhu Zhiwei is a teacher at South China University of Technology. He said"With this technology, the preservation period of lychee can be increased to one year. It allows people to enjoy the fresh fruit all year round."

 Once picked, the fruit only lasts around two or three days. In the fridge, lychee   can be stored for about 10 days. But the new technology can quickly freeze lychee below - 35℃ to store for one year. People now try to use the method to keep more than2000 tons of the fruit fresh. The technology will help solve the problem of selling bad lychee and selling them in high prices. And it will improve the quality of lychee in the future. With the help of it, lychee can keep the bright color and the good taste for a long time. It can be sold to other countries, including the United States, Japan, England and so on.

 The technology is safe and easy to use. It can also be used to keep other foods and vegetables fresh in the following years.
