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.
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。
“啊……”家里传来一阵又一阵的叫喊声,我们闻声赶来,只见哥哥捂着肚子,在地上不断打着滚,还伴有轻微的抽搐。
妈妈顿时大惊失色,连忙蹲下身来,一把抓住哥哥就往身上背,瘦小的妈妈竟背起了百来多斤的哥哥,心急火燎地开车前往医院。
妈妈刚走的几分钟,我欢呼雀跃的高蹦着,在平时,妈妈会立刻阻止我,迎接我的却是一片黑暗,我的心空落落的像没有依靠一样,家里连一只苍蝇扇动翅膀的声音都能听得一清二楚。我依靠在椅子上,昏黄的路灯照在家具上,打开的抽屉似一只大手,紧紧抓住我,这时铃声“叮叮”的响了起来,我扑了过去,是妈妈打来的`。“喂!儿子,今天我不回来了,哥哥要做手术。”电话里传来妈妈那万分抱歉的声音,“什么?哥……哥要做手术?”我惊讶地只能目瞪口呆了,一屁股坐在地上,原先的好心情烟飞烟灭。
我的心像被什么抓住了,呼吸不能自已,只好像鱼一样张大嘴巴,我猛地吸了口气,闭上眼又缓缓吐出,心却仍难以平复,我多想打电话啊!虽然我知道会打搅她,妈妈离开的几分钟,对我而言,却是几个世纪般长,我像疯子一样狂拨着电话,那头只是一长串的“嘟”声。功夫不负有心人,终于通了,“哥哥马上就要做手术了,就这样。”未等我倾诉心中的思念,妈妈就挂了。我知道哭是没用的,于是找来各种杂事来打发过去:去洗拖把,来拖地,拿起铅笔扒在桌上狂写。
尽管这样,心中的盼望,如煮在锅中的粥益发浓稠了,窗上的小雨下着,窗内的本子受着淋,那在黑夜中亮起的明灯,似陨落在尘间的星星,更是那颗无时不盼妈妈回来的心。
闭上眼,听,雨在下着,那片独云在哭泣,它将思念的泪洒在风尘中,悄然的“梅花”绽开。
Dear Mike,
You asked me about the present situation of the public transportation in Wuhan in the last letter.
Now, I will communicate the action of the government and my opinion with you.
Firstly, the price of the bus has been cut down, which is very important, I think. Encouraging people to take bus can solve the biggest problem--too much people.
Another way is to develop the bike rental. As we know, car is much bigger than the bike obviously. Driving a car takes up much more place than cycling. So, developing the bike rental is an absolutely correct way to prove traffic circumstances.
Besides, government also builds 4 subway lines under the central of the city and increases the number of the taxis.
In my opinion, all the action above is useful. When the actions above are all finished, the city will be more perfect.
Yours,
Li hua
下面谈谈学习毅力的.问题。如果你有坚强的毅力,那么世界上就没有什么难事。学英语关键是能够持之以恒。
在学习过程中,你应该制订一个计划,一天记住几个单词,一天记住一两个句型。你不要小看“持之以恒”的力量。举个例子:
如果你一天背5个单词一年就是1825个单词,相当于初中三年再加高中一年零两个月的词汇量。如果你坚持两年你就能住3650个单词,相当于中学六年包括本科两年的词汇量。
在制订计划时要遵循以下几项原则:
1、计划要切实可行,不要好高务远。上面的例子已经说明,只要你能坚持天天学习,英语一定能学好。
2、要有坚强的毅力,每天都学习,不因为某些事而耽误了学习。如果哪天的工作没有完成,第二天一定要补上。连续不学习的时间不要超过两天。
3、要有一个帐本,哪天学会了哪几个单词,哪几个句型一定记录在案。
4、为了把单词、句型真正学到手,第二天一定要复习第一天的,第三天一定要复习第二天和第一天的内容。
5、所选择的课本可以是一套或两套,千万别太多。实际学英语的书没有什么好坏之分,只要你能按照一套或两
