不保护好牙齿会结石作文【一】

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.

小猪乖乖从小就特别喜爱吃糖,使牙齿掉了好多,只剩下了几颗了。可是,小猪还是一如既往地吃。

一天,小猪满头大汗地从外面跑回家来,拉开抽屉,拿出盒子,从盒子里拿出了许多糖吃,刚准备进入口内,妈妈见状立即把糖一把夺过来,说:\"小猪乖乖,你还吃糖!牙已经剩下了几颗?你还吃!\"小猪不情愿地嘟嚷着说:\"我要吃嘛!我就要吃嘛!\"妈妈叹了口气说:\"唉,真拿他没办法!\"

又一天,小猪趁妈妈不在家,偷偷地在妈妈房间找糖吃,他东找找西找找,终于在妈妈的保险柜里闻到了糖的味道。但是,小猪不知道保险柜的密码,就先把妈妈的生日作为打开保险柜密码,可是,保险柜不但没有打开,而且小猪乖乖还触了电,把他吓了一大跳,他又把爸爸的\'出生年月为密码。终于,皇天不负有心人,小猪终于打开了保险柜,高兴地手舞足蹈,总算从保险柜里把糖拿到手了,小猪的脸上乐开了花。

小猪从保险柜里拿到了糖后,他飞快地吃起了糖,生怕妈妈回来吃不了,糖越吃越少了。最后,小猪怕妈妈给发现了,就恋恋不舍地把糖放进了保险柜里。不一会儿,妈妈回来了,用菜做成了糖的形状,希望小猪能喜欢吃,但是,小猪不喜欢吃。

当天晚上,小猪的牙齿忽然疼了起来。狗医生一检查,是虫子在作怪,就对小猪说:\"你的牙齿蛀牙了。这都是因为你平时老爱吃糖,不听别人的劝。以后,别再吃糖了,这样牙齿就不会再蛀牙了,记住我对你说的话了吗?还有这副药,是治蛀牙和治牙痛的,一天三次,一次两颗。\"\"嗯!\"小猪忍着痛说。

小猪按照狗医生说的去做了。从此他的牙齿再也不疼了,而且,也不蛀牙了。小猪说:\"这要感谢狗医生,要不是他,我的牙齿就蛀掉了。\"
