Ask your friend that he can use a glass of water as a musical instrument. Of course, he can’t.
Next, you take a glass of water, put your finger into the water and then move it slow round the
rim of the glass, as showing in the picture. Your finger must not be too wet, but it must be dry. So you have to try many time. At last you will hear clear music which came from the glass. When your finger moves round the rim, it makes the glass to vibrate and the glass makes a musical sound. The same principle makes the violin or its strings give music.
The America scientist Benjamin Franklin made a musical instrument out of glass bowls, using the different principle.

One day, a little girl felt down onto the ground．A boy went over and wanted to help her up, but his mother stopped him, say, “Don’t do that, or others will think you had knocked her down.”
Another day, the mother, much surprised, saw that their son just watched the fallen oil bottle lying on the ground as if nothing has happened．When asked why, the son answered, “If I had help the bottle up, you would have thought that I did it.”
I don’t agree with what the mother did．I think that parents should let their children to know it is a pleasure to help others who is in trouble．We are big family．We should care for and help each other．

Dear Tom,
How time flies! We will have to say goodbye after a week, but I will never forget the beautiful days when we spent together. In my memory, you are such kind a person that you will always offer me help wherever I get into trouble. You are the most considerate person who know exactly what I need in our class.
Do you still remember that night twenty years ago? When I suddenly fell ill, you carried me to nearest hospital. Moreover, you attended to me careful while I was staying in hospital. Later, you managed to help me with my lesson. Without your help, I can not have passed the exam. Though we are parting soon, but I will keep the favors you’ve ever done me in mind.
Best regards
LiHua
My little cousin is greatly interested on science. And he does some dangerous experiments sometime. Although his parents want to encourage him to be great scientist, at times they worry about his safety. Last week, when my cousin was doing an experiment, he hurts his thumb. My aunt felt sadly and wanted him to stop from doing that experiment. However, my cousin didn’t want to give up. She said, “Many scientists got hurt when they were doing experiments, so they didn’t give up.” My aunt had to let him finish the experiments and he finally succeeded in finish it.

In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successful flew over the South Pole for the first time. Therefore, at first, Byrd and his men were able to take great many photographs of the mountains that laid below, they soon ran into serious troubles. At one point, it seemed sure that their plane would crash. It could only get over the mountains if it raised to 10,000 feet. Byrd at once ordered his men to throw away two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd then knew that he would be able to reach the South Pole which was 300 miles away, for there was no more mountains at sight. The aircraft was able to fly over the endless white plains without difficult.
