40年前,黄河入海口曾经是鸟类的乐园。后来,随着黄河三角洲地区河水水量的减少以及人为的开垦,这里的湿地面积减少了,来访鸟儿的数量也减少了。
近年来,黄河三角洲湿地生态系统明显改善。现在,每年都有近百万只鸟到这里越冬栖息,它们中有许多是世界珍稀种类。黄河三角洲湿地保护只是中国在保护湿地方面的一个成功例子。它反映中国在保护湿地方面取得了很大成效。
中国现已建立353个湿地自然保护区。湿地自然保护区的建立还保护了中国大江大河的源头,主要河流入海口,以及候鸟繁殖和越冬栖息地。
目前,湿地保护仍然是中国生态建设中的一个薄弱环节。中国政府将采取有力措施制止掠夺性开发湿地资源的行为,以保证湿地资源的可持续利用。

C

By far the most common difficulty in studying is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work to a plan and have no regular routine of study. Many students muddle (胡乱对付) along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment.

Few students work to a set timetable. They say that if they did work out a timetable for themselves they would not keep to it, or would have to change it frequently, since they can never predict from one day to the next what their activities will be.

No doubt some students are more willing to accept a regular routine than others. There are many who shy away from a self-controlled weekly timetable, and dislike being tied down to a fixed program of work. Many able students state that they work in cycles. When they become interested in a topic, they work on it attentively for three or four days at a time. On other days they avoid work completely. It has to be admitted that we do not fully understand the motivation (动机)to work.. Most people over 25 years of age have become used to routine, and the majority of real productive workers set aside regular hours for the more important areas of their work. The “tough-minded” school doesn’t fully accept the idea that good work can only be done naturally, under the influence of inspiration.

Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of “freedom”. In fact, freedom from control and discipline(纪律)leads to unhappiness rather than to “self-expression” or “personality development”. Our society insists on regular habits, timekeeping and punctuality (准时), and whether we like it or not, if we mean to make our way in society, we have to meet its demands.
