Dear Lily,
How is everything?I do not see you for a long time, and I miss you very much. So I write to you. Iwas very busy in the last month, because I have much homework to do. The finalexam is coming, so I must work hard. Besides, I must learn piano very two days.It takes me some time, but I feel happy. These are my life in recent. And what’syours? I am looking forward to your letter and tell me about your life.
Sincerely Yours,
Carla
the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
Dear Amy,
亲爱的艾米:
Long time no see. How is everything going? I am writing to tell you a good new about me. I received my high school admission this morning. It is No.1 high school in my hometown. You know that it is my dream school. I am so excited to share this good news with you. You will be happy for me, right? Now, it is your turn. How about you? Have you receive you admission yet? Have you come back from your Guangzhou trip? I am eager to know your life recently. Look forward to your replying.
很久不见。最近怎么样了?我写这封信给你是想告诉你我的一个好消息。我今早收到高中入学通知书了。是我家乡的第一高中。你知道的,那是我梦想中的学校。我 真的很激动,所以急于跟你分享这个消息。你会为我感到高兴的,是吗?现在,该轮到你了。你怎么样了?收到通知书了吗?你的广州之旅结束了吗?我很想了解你 的近况。期待你的回信。
Best wishes,
Li Hui
