it has been said that when people succeed，it is because of hard work and that luck has nothing to do with success．although i believe that hard work is very important and is the surest way to success for most people，i must disagree with this statement．it cannot be denied that luck often plays an important role in success．for example，many important discoveries have been made by accident．there have been many cases of researchers and inventors making major breakthroughs while they were actually trying to solve another problem or create a different device．

furthermore，there is something to be said for simply being in the right place at the right time—perhaps meeting someone by chance who can offer a good job or rare opportunity．and of course，there are the rare examples of gamblers and lottery winners who beat the odds and achieve sudden and unexpected success．

while the influence of luck cannot be ignored，this is not to say that one should depend on it and ignore the value of hard work．if one is willing to work hard，i believe that success will eventually be achieved，with or without the added benefit of luck．moreover，hard work is often an essential ingredient of luck because it enables one to take advantage of a lucky encounter．if the scientist has not worked hard to develop his knowledge and skills，he may not recognize that lucky breakthrough when it comes along．therefore，my suggestion is not to count on luck to bring you success．instead，work hard and keep your eyes open for that lucky opportunity．

水是生命之源，我们要保护每一滴水。这句话每个人都是知道的，但是又会有多少人能够做到这一点呢?人们老是洗完手不关水龙头，用完淘米的'水就那么倒掉，浪费掉。

我们每人的生活都离不开水，在洗脸的时候要用;在喝水的时候要用;甚至是在小孩子玩泼水的时候也要用……水是那么，那么的重要但是人们还是不停的在浪费水。

有一次，我们一家人到奶奶家去吃晚饭，我们都津津有味地吃着美味的饭菜，我吃完后，发现手特别脏，便进了洗手间去洗了把手。突然看到一个大型的脸盆正在接着从水龙头里慢慢滴下来的水，那时水已经滴了脸盆的一半了，我便立刻去问了奶奶：“奶奶，你怎么不关水龙头呢?那样很浪费水的呀!我把它关了吧!”“不用，不用。”奶奶笑着说，“那是我是故意开着的，盛点水总是要用的呀，对吧。”我便没有说什么，过了几分钟后，我又去了一趟洗手间，我看了看里面，只见那个脸盆早就已经装满了，水都已经哗哗地扑出来了，便对奶奶说：“奶奶脸盆里的水装满了!”“那你把水龙头关一下吧。”奶奶说。我心想：在扑出来的几分钟里，也不知浪费了多少的水啊!

不仅是节水，我们应该多做一些环保的事情啊!

open courses

online open courses are gaining popularity in recent years. following globally famous universities like yale and harvard, some universities in china have also started to offer online open courses. those courses have attracted people from all classes with different occupations.

the courses have brought many benefits to people. many of the courses are provided by universities in foreign countries, and thus offer fresh ideas to us. through them, we can keep up with what people are thinking all over the world. but that can also be a problem. some of the courses may not be very suitable for chinese students because of cultural differences and may cause chaos on chinese campus.

in my opinion, online open course is useful and we should make use of it to broaden our horizons. but we should also remember to have our own thinking and not be brainwashed by improper ideas.
