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 Chris,
How are you doing? Recently, an important volleyball game will be held in our campus, which will be not only meaningful but also exciting. So, as captain of the team, I, on behalf of all our team members, am writing to invite you to join us in the battle!
Here are some relevant details about it. To begin with, it will be on the 3rd volleyball court from 2:00 to 4:00 on the afternoon of July 1st. Besides, we, the Giants, will confront the Eagles, which is undoubtedly a tough rival. As a result, adequate preparation is urgently needed, including practice, nutrition and a perfect plan.
Hopefully, you could make it to this wonderful event. We need you! Looking forward to your reply and your presence.
Yours,
Li Hua

世上有没有两个完全相同的人呢?答案肯定是没有。也就是说每个人都有不同于别人的地方,所以对于熟悉的人,即便是双胞胎,我们也能区分开。写人其实就是写“特点”,也就是跟别人不一样的'地方。无论外貌、表情、性格,一定都有他(她比较突出的特征。
比如说长相,大眼睛小嘴巴的人很多,所以类似“黑漆漆的大眼睛,红润的小嘴巴”这种描述在别人脑海里会显得空洞,可是加上一些独特的表情,像“笑起来会皱鼻子”,“常常不自觉地眨眼睛”,“嘴巴有点噘,好像总在生气”,“鼻头大大的,似乎占了脸上一半的位置”......人物就会显得比较生动,怎样写好作文《怎样写好写人的作文》。可以试着让孩子去描述不同的京剧脸谱,看家长能不能猜出来是谁,也可以念念《西游记》《水浒》等经典名著里对每个人的不同描写,让孩子画出来......只要养成抓特点的习惯,外貌描写就不会千篇一律了。写到这儿,我想起很多名人被抽象的漫画,虽然严重失真,可是我们还能一眼就认出是谁,那就是抓特点的典范了。
至于人的性格,孩子们往往喜欢写得很完美,这世间哪有完美的人呢?想想好吃懒做又重情重义的猪八戒;极度怕老婆,屡战屡败又屡败屡战的灰太狼;不爱学习又善良天真的樱桃小丸子......他们都满身缺点,却一样招人喜爱。真正让人感动的并非是一贯高尚的人做了一件乐于助人的事情,而是我们身边默默无闻的小人物在关键时刻显示出本质的善良和热心,甚至一鸣惊人,这点美国大片里有很多实例。一个人物写得好不好不在于你把他(她写得是否高尚,是否完美,而在于有血有肉,性格鲜明,读者虽然没见过他们,眼前却能浮现出他们的举止模样,这才是文字的魅力所在。
找到人物的特点,然后去想在他身上发生的什么事情最能体现出他的这个特点,让这个人在你的笔下活灵活现起来,那就是一篇很好的作文了。建议从一段话练起,细细描写动作、表情,刻画心理活动。慢慢地,就发现自己“下笔如有神”了。
