先说一首歌吧。现在的一首歌,一般分成两段,你看这两段是不是基本上差不多,基本上是重复的呢?再有歌中关键的一句,更是重复5,6遍,7,8遍之多。我们并没有感到厌烦,反而觉得应该重复,不重复,就意犹未尽。
再比如学唱一首歌,很少有人听一遍之后,一首歌就学会唱了,除非他是天才。一首新歌,你要学会,不说多高的要求吧,就达到听起来还可以,不跑调这样一个要求。要达到这样一个要求,你不知要重复的唱多少遍才能达到。没有这一遍一遍的\'重复,你就学不会。
再比如体育运动,如跳水,体操,就那么几个动作,运动员做下来,很漂亮。可这几个动作,运动员在训练时,不知要重复多少遍,何止百遍千遍啊!
做学问,也需要重复。读书百遍,其义自见,是重复;好文章不厌百回读,是重复;孔子读书,韦编三绝,是重复;
我们的学习也是这样。很多同学不喜欢重复。比如做题吧,一看一道题以前做过,就扔在一边不管不问了。你是不是真正会做了啊?即使会做了,你能熟练的准确的把它做出来吗?一道题不仅要会做,还要做得熟练准确,还要能透彻的理解,能举一返三。题,包括高考题,我们都似曾相识,完全陌生的题并不多。每次高考考下来之后,大多数同学兴高采烈,喜形于色,都说不难!,都做上了!可成绩下来之后,也是几家欢乐几家愁。那些曾认为不难,都做上来的同学,成绩往往不理想。这说明这些题虽然你会做,但熟练准确程度不够。所以我们不要害怕重复。一道题,你不妨多做几遍。一道好题,你做10遍,比10道题你只做一遍效果要好得多。
重复实在是学习进步的法宝。

Suppose you have found something wrong with the electronic dictionary that you bought from an online store the other day. Write an email to the customer service center to
1 make a complaint, and
2 demand a prompt solution.
Dear Sir or Madam,
I bought/ordered an electronic dictionary from your online shop on January 1st, but I found it has some problems after using it for a short period of time.
To begin with, the battery needs recharging after a mere 2 hours of use. This means that I need to carry my charger with me when I go out for a day. In addition, the buttons on the electronic dictionary are so small that it is nearly impossible to type anything with them. Personally, I found this to be completely unacceptable.
Therefore, I would like either to change for another model that works well or a full refund. I am looking forward to your prompt reply.
Yours sincerely,
Li Ming

所谓重复利用,字面意思是把一样用完的或者没用了的的东西重复作用。也就是说,人类把一样用很多资源制造出的东西作为废品晾在一旁、扔掉,很可惜。其实“废品”可以重复利用,那就得用上举例说明了。
在班会上,“科技小才女”于佳介绍了一个引人深思的东西。她手里拿着一个圆圆的\'小碗,可是颜色、样子好像不怎么像平时见到的碗一样,什么东西呢?她见到我们好奇的眼光,微微笑了一下,然后不紧不慢地说:“大家很好奇吧?这就是一只碗。眼尖的同学一定发现,这个碗有那么点与众不同吧!那谁来猜猜?”马上有很多同学“踊跃发言”,大家异口同声地说:“颜色、样式有点不同——”有同学故意拖音,于佳也不甚在意,她接着说:“对啦!那谁猜猜猜它是什么做的?”于佳故意调皮地拖音,正好,大家也不知道,一片死寂沉沉……39双眼睛死死的盯着于佳手里的小碗,好像要看个什么究竟出来。于佳会意的笑笑,说:“没人知道?(这里故意拖音卖关子了一下)嘿嘿,这个过程可是很‘艰难’的!它是用旧报纸一片一片好不容易粘成的,用了好几天才晒成的。”马上,好多人议论起来:“硬不硬?”“能用吗?这是手工还是实用品啊?”“好厉害啊!”“就是就是,花了不少功夫吧?”……于佳又说:“它是很硬的,几乎可以用的。你们大家不妨扮扮看!”小碗被传到了一个个同学的手里,我接到它时,特意小心地扮了扮,不过扮后,我一点也不小心了,因为——真的很硬!我感悟道:“啊!以前看完了报纸,就以为它这样东西没有用了,没想到啊!居然能作尘这么可爱漂亮又实用的小碗!厉害!”于佳接过话头,很激动地说:“是啊!每年为了制这些报纸,砍了多少大森林啊,不,应该说‘毁’!(读到这里时,情绪异常激动)同学们说的太对了!就这么白白浪费,我们不如试试‘重复利用’!”大家安静下来,班里仿佛掉一根针都能听见声音!大家都在思考同一个事:报纸也能做成这么有用的东西啊!大家情绪有点低落,于佳马上接着说:“很多东西,都能重复利用,正因为地球资源有限,所以大家要好好利用,千万不能浪费啊!我的发表结束了,谢谢大家!”班里马上响起雷鸣般的鼓掌声。当然当然,还有很多同学举了很多例子呢!东西重复利用,真的是很重要啊!
地球资源一定要好好珍惜,大家共有、只有一个地球,大家一起努力,才能让它永远“年轻”!
To Whom It May Concern,
I am a student in this university who regularly comes to the library to spend my spare time. Generally speaking, the services you offer here is quite good; however, I have some suggestions for you to adopt.
To begin with, will you please prolong the time for reading? In the daytime, most of the students are having class, so they can’t come to the library. Moreover, some of the books on shelves are out of date. If you are so kind as to provide us some books such as the latest magazines, we will be greatly honored.
I really wish to have a more comfortable library. I would like to extend my greatest appreciation if you are so kind to take my suggestions into consideration. /Thank you for your time and consideration.
Sincerely yours,
Li Ming

Restrictions on the use of plastic bags have not been so successful in some regions. “White Pollution” is still going on. Write a letter to the editor(s of your local newspaper to
1 give your opinions briefly, and
2 make two or three suggestions.
Dear Editor,
I have been reading your newspaper for many years with a great enthusiasm and interest. It is my honor to write you this letter to give my views on the issue of “White Pollution”. It is my view that the limitation of the use of disposable plastic bags is of utmost significance.
I would like to make the following suggestions to put an effective stop to the wide spread of “White Pollution”. Firstly, we should ban the free use of the plastic bags. Secondly, the price of plastic bags should be further raised. Thirdly, media like your newspaper should do more to encourage the public to use paper or clothing bags to replace the plastic bags.
I hope my suggestions would be of help and thank you for your attention.
Yours sincerely,
Li Ming
