What will you do if you meet an alien? Here are some different opinions from the teenagers.

    Jenny: Aliens are always mysterious (神秘的) to us. In my mind, aliens are very dangerous because we don't know them very much. So, if I meet an alien, I will run away from him{#blank#}1{#/blank#}I can. I don't want to be killed by him. If I'm{#blank#}2{#/blank#}and get caught by him, I will keep cool and then try my best to{#blank#}3{#/blank#}. I won't risk my life to get along with the alien, even if he seems{#blank#}4{#/blank#}. I am too frightened to meet them.

    Tom: If I have a chance to meet an alien, I will feel very lucky. I believe that everyone has{#blank#}5{#/blank#}living on other planets. I want to make friends with the alien. I want to know more about the life on his planet. I will ask him about the{#blank#}6{#/blank#}between the Earth and his planet. Maybe it is crazy, but I will{#blank#}7{#/blank#}the alien to my best friends. I think we will learn many{#blank#}8{#/blank#}things from talking with the aliens. We will become friends.

    Bill and Cathy wanted to go on a holiday. They chose a place called Maldives（马尔代夫）. And they decided {#blank#}1{#/blank#} there for two weeks in spring，because the {#blank#}2{#/blank#} there was perfect at that time. They thought they would have a {#blank#}3{#/blank#} trip. But their tip was more like a nightmare（噩梦）!

    The plane {#blank#}4{#/blank#} off twelve hours later because of the bad weather. And they couldn't fly to Maldives {#blank#}5{#/blank#} there was a storm. They had to fly to the capital city instead. There they stayed in a small hotel near the airport.

    The hotel was next to the sea, {#blank#}6{#/blank#} the sea was so dirty that they couldn't swim in it. The food in the hotel was awful, too. For breakfast there {#blank#}7{#/blank#} only bread and milk! Because of the bad weather, they had to stay {#blank#}8{#/blank#} another night in the small hotel. And they had {#blank#}9{#/blank#} to do. It was so boring. {#blank#}10{#/blank#} , they arrived in Maldives three days later. And someone told them the weather there had been wonderful all the time!

There are many colors in nature. But do you think that a color has weight? Let's do a test.

First, put two objects with the {#blank#}1{#/blank#} weight into two boxes. Then cover the boxes. Third, wrap (包裹) one box with a red piece of paper, the other with white. Now hold the boxes {#blank#}2{#/blank#} your hand one by one. Which one is {#blank#}3{#/blank#} ? It is certain that you will think the red one is heavier. Why do you think so? A scientist did many {#blank#}4{#/blank#} and found that different colors have different weights in a man's mind.

Also, scientists say that people accept the colors they like, and {#blank#}5{#/blank#} the colors they hate. So your body and mind will be {#blank#}6{#/blank#} by using the colors you like. Or you'll be nervous {#blank#}7{#/blank#} even get ill. For example, you {#blank#}8{#/blank#} blue and hate red. If you stay in a room with red windows and wallpaper for two hours, you'll feel you have been there for {#blank#}9{#/blank#} hours. But if the room is blue, you'll feel you have been there for only an hour, And, if a person walks {#blank#}10{#/blank#} of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colors.
