To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
相传有一位阿拉伯老人,生前养有11匹马,去世前立下遗嘱:大儿子、二儿子、小儿子分别继承遗产的1/2、1/4、1/6。儿子们想来想去没法分;他们所得到的都不是整数,即分到分别为11/2、11/4、和11/6,总不能把一匹马割成几块来分吧?聪明的邻居牵来了自己的一匹马,对他们说:“你们看,现在有12匹马了,老大得12匹的1/2就是6匹,老二得12匹的1/4就是3匹,老三得12匹的1/6就是2匹。加起来一共是11匹,现在还剩一匹,我还是把它牵回家去。”就这样,邻居把难分的问题轻松的.解决了。
数学其实在我们生活中无处不在,不仅仅是分数在生活中有很大的用处,还有很多数学方法也为我们提供了方便。当然也有更多还没有出现、解决的数学问题,它们是什么,就等着我们一起到数学的海洋去探讨发现了!
作文点评:
这是一个流传很广的智慧故事,说说笑笑而已。写得不错。作为文学作品,很精彩。
How to prevent the H7N9?
As is well known,the A flu is spreading throught our country. However, if we negnect it, the deadly H7N9 may cause more infectors,or even more deaths. So what is the most important is that we should take some effective measures to prevent it.They can be listed as follows.
Firstly,it is necessary for you to realize the Avian flu can be prevented if you develop good living habits. For example,you shouldn’t forget to wash your hands before meals.Besides,don’t spit everywhere and try to cover your mouth or nose with paper or hankerchiefs when you have to cough or sneeze.What’s more, remember to wear the mouth-cover if you have to go to the public places, such as the crowded cinemas,supermarkets, buses,where the A flu may spread easily.
Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
Last but not the least, if you are unlucky to be infected with the slight flu cold, try to stay at home,and take some medicine. Do pay attention to your daily body temperature. If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.
Only by doing like this can you prevent or defeat the A flu in the end.
