小学写作文知识点【二】

在今天政治课上时,偶然看到一则小故事,讲的是:一位农场主的收割机出了毛病,他和他的朋友都查不出什么毛病,所以请来了一位这方面的专家,专家仔细查看了收割机,然后朝马达部位用锤子敲了一下,收割机恢复了正常,专家要收费100美元,而农场主则嫌贵,专家解释说:我这一锤子只要1美元,而往哪敲这点知识则值99美元。

由此可见知识的价值多么宝贵,而要获得知识我们可以通过老师传授,互联网,从电视,报纸,来获得知识。

正如左拉所说:只有知识——才能构成巨大的财富的源泉,既能使土地获得丰收,又能使文化繁荣昌盛。愚昧重来没有给人们带来幸福,幸福的`根源在于知识只是会使人精神和物质的荒芜的土地变为肥沃的土地,每年他的产品将以10倍的增加给人们带来财富。

在21世纪只有知识才能使命运发生转折各种各样的竞争潜伏在我们周围,只有心中有知识才能养活自己。

我们要奋发图强才能明白知识的价值。

小学写作文知识点【四】

家中起火,不要慌张,应根据火情及时采取相应措施:如果炒菜时油锅起火,迅速将锅盖紧紧盖上,使锅里的油火因缺氧而熄灭,不可用水扑救。当房间内起火时,不能轻易打开门窗,以免空气对流,形成大面积火灾。纸张、木头或布起火时,可用水来扑救,而电器、汽油、酒精、食用油着火时,则用土、沙泥、干粉灭火器等灭火。若火势已大,必须立即报火警。被火围困时,应视不同情况,采取不同方法脱离险境。如俯下身体,用湿布捂鼻。

路上被人抢劫、敲诈和勒索怎么办?

(1)要保持冷静,不要害怕,尽量说好话,跟他们说明自己没带钱,避免被他们绑架。

(2)如果他们继续坚持要你拿钱,就跟他们说我回家取钱,先放掉我并趁机跑掉,并向你认识的人求助。

(3)如果一个人遭挟持,不要反抗,不要“硬碰硬”,可以给钱,但要记住对方的相貌和特征,事后向公安局报案。千万不要拉住欲跑的持刀歹徒不放,这样容易造成歹徒狗急跳墙,持刀伤人。

小学写作文知识点【五】

2、近似数:根据实际需要,我们还可以把一个较大的数,省略某一位后面的尾数,用一个近似数来表示。例如:1302490015省略亿后面的尾数是13亿。

3、四舍五入法:要省略的尾数的最高位上的数是4或者比4小,就把尾数去掉;如果尾数的最高位上的数是5或者比5大,就把尾数舍去,并向它的前一位进1。例如:省略345900万后面的尾数约是35万。省略4725097420亿后面的尾数约是47亿。

4、大小比较

(1比较整数大小:比较整数的大小,位数多的那个数就大,如果位数相同,就看最高位,最高位上的数大,那个数就大;最高位上的数相同,就看下一位,哪一位上的'数大那个数就大。

(2比较小数的大小:先看它们的整数部分,,整数部分大的那个数就大;整数部分相同的,十分位上的数大的那个数就大;十分位上的数也相同的,百分位上的数大的那个数就大……

(3比较分数的大小:分母相同的分数,分子大的分数比较大;分子相同的数,分母小的分数大。分数的分母和分子都不相同的,先通分,再比较两个数的大小。
