the summer vacation had come round again. i was happy that i could forget about school at least for a while. lest i fool around all through this summer vacation, i made a plan as to how to spend it. first, i thought i should go over all those things my teachers taught in the previous term so that i could have a better understanding of them.
then i thought i should take up some forms of exercise, such as walking, running and rowing, to keep me physically strong. it stood to reason that with such a good plan i should make the best of my vacation time. i did, because i lived up to what i had planned.
At college, I missed my parents a lot. As the term was drawing to an end, I eagerly looked forward to going home. And I planned to do a thousand and one things during the vacation. Above all, I wanted to help my mother with housework. I also wished to read many hooks which my teachers had recommended. However, at home, my mother would never let me do anything. She completely deprived me of sharing her work. As soon as I opened a book to read,she would sit down beside me and ask me about all kinds of things at the college. To please her,I told her one thing after another,and soon I forgot all about books. Even when I was actually reading,she would, now and then,insist that I should eat an egg or drink a cup of tea. When I left home at the end of the vacation, not a thing in my plan had been carried out. But I felt very happy. I believed much more deeply than before in the old saying: Home, sweet home. There’s no place like home!

I went to the countryside to spend my summer holidays this year. I liked green plants, clear rivers and lovely amimals there.I breathed the fresh air on the mountain and sometimes I went swimming in the river. I kept a diary every day.
I liked not only the scene of the countryside, but also the people there. I helped them to do farm work. I also helped the children in the neighbourhood with their lessons. The children were interested in English. They were good at reading and writing, but did not do well in listening and speaking. I helped them improve their listening and speaking. Their parents thought highly of me. I realized that knowledge is greatly needed in the countryside.
My holiday life will be busy but interesting. I am going to do my homework every day so that I can finish my homework on time.I am going to the library to borrow some books and go to the shops to buy some books so that I can read some interesting books. I am going to play sports such as playing basketball, table tennis, swimming and so on . Of course I am going to help my parents do some housework because they are busy with their work every day.I am going to spend a week in Shanghai with my parents so that we can see the expo. I am sure I am going to have an interesting and happy summer vacation.
动物跟人一样,都需要休息,而且大部分的动物和人睡觉时都会闭上眼睛。可是,你见过金鱼闭上眼睛吗?我想你肯定没见过。
那是不是金鱼不睡觉呢?当然不是,金鱼和我们一样,它也会睡觉,只是我们不容易察觉而已。
其实,金鱼在水中不动时,就是在睡觉,只是因为鱼没有眼睑,所以不会闭眼,看上去就像不睡觉一样。
鱼也有各种各样的睡觉方法。仔细观察我们饲养的金鱼,你就会发现,它们到了夜晚,就会躲到鱼缸内的小假山、水草间等暗处一动不动,这就是金鱼睡觉时的状态。鱼不像人那样有眼睑,在睡觉时能够闭上眼睛。因此,要想看到金鱼睡觉还真不是件容易的事。
除了金鱼,人们还了解到了其他一些鱼类睡觉的状态。如花海猪鱼、细拟隆头鱼、锦鱼等,它们都在海洋底部生活,当夜色来临时,它们就会钻进沙子里,一动不动地睡大觉,这样既安静又能有效地防止天敌的伤害。还有一些鱼如裂嘴鱼、南洋鹦嘴等,它们的身分泌一种特殊的'胶状物质,要睡觉时它们就像小孩子一样吹个大泡泡,胶质的泡泡遇水后会硬化,它们就钻进那个泡泡里,只在嘴边留个小孔,就像在睡袋里一样。
在淡水里生活的鱼大多跟金鱼一样,躲在岩石后、水草间等暗处睡觉。像鲤鱼、鲫鱼会钻进水草里睡觉,而鲻鱼、鲷鱼则在岩石后面睡觉。
有趣的是,还有些鱼类睡觉的时候不需要停下来,像有洄游习性的鱼就能够一边游泳一边睡觉。如金枪鱼、鲭鱼和嘉鱼,不管白天晚上都在不停地游动,使得我们很难弄清楚它们什么时候是在睡觉,什么时候是清醒的。
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.
