Sometimes I dream about life in the future. What will it be?
Perhaps some people will go to the moon for a holiday or even live on the moon,and some scientists will build cities under the sea to make people live there. We can have a medical examination or do some shopping without leaving our homes,which makes the life more convenient. Maybe we will also do some shopping and work at home.
And I'm sure there'll be more educational programmes on the radio or TV or by the Intemet or videophones,so perhaps some children won't need to go to school every day. They'll study at home.
In the future,all electric equipment at home is under the con-trol of computers. People can learn about the situation of the house by working on the computer at the office. No people like doing housework. Maybe each family will have a robot. Every day we can tell the robot what to do-shopping,housework and so on. believe the dream will come true some day.
2.1 将水利水电工程与生态工程联系起来
目前,水利工程设计基本都是考虑工程水文学,实际上,水利工程的建立对人们的生活也造成了很大的影响。生态的破坏并不是人类发展的初衷,在专业化考虑的基础上,也应适时结合生态学。将生态学与水文学进行有机结合,考虑到各个方面的发展,这样才有利于水利水电工程的长足发展,才不违背人类发展的初衷。生态学为设计者提供了生态用水的理念,提供了自然发展平衡的思想,只有遵从这些理念,水利水电工程的建立才算是真正帮到了人类。因此,需要更好地将工程水文学与生态水文学相互融合,为生态水利工程的设计提供宝贵和事实依据。在生态发展平衡的前提下,谈论水资源问题才不会本末倒置,从而使水利水电工程的设计更加符合生态发展规律。
2.2 合理规划和开发
建立水利水电工程时,要进行合理规划和开发,最重要的是要遵循可持续发展观,长期发展才是最终目的。因此,在水利水电工程的建立中,需要对生态环境进行全面、深入的调查,对库区附近的土地资源、水资源等各项资源的分布、开发情况进行全面了解,根据实际情况考量,最终决定建立的地点、时间和规模,做到生态效益与经济效益的双赢,切不可盲目、大量地开发利用资源,为了眼前的利益而造成资源的浪费和生态的破坏。
2.3 改善生态环境
我们应积极改善生态环境,比如设计净水系统或排水系统,对水资源的破坏降到最小。同时,要有针对性地减弱工程对河流生态的影响,因地制宜。
City traffic is a big problem in some cities in the world, especially in big cities. To solve the problem, someone are in favor of developing buses as means of city traffic. Others are in favor of the subway. Between them,which is the better choice?
在世界上的一些城市中城市交通是一个大问题,尤其是大城市。为了解决这个问题,有人赞成发展公交车作为城市交通的方式。另一些人则赞成地铁。在它们之间,哪个是更好的`选择?
It is easier to take buses as means of city traffic than the subway trains because buses don't need special roads. But buses have also many disadvantages, some of which are very serious. They may cause louder noise and more traffic accidents. Buses give rise to serious air pollution and traffic jam. In order to stop what buses cause, a large amount of hand must be used to widen the roads. On the contrary, the subway train is of more advantages. Except the difficulty and high cost of building the subway, it is superior to the buses in many aspects.
公共汽车作为城市交通方式要比地铁容易,因为公共汽车不需要特别的道路。但是公交车也许多缺点,有些是非常严重的。他们可能会导致噪音和更多的交通事故。公共汽车也导致了严重的空气污染和交通堵塞。为了阻止公交车带来的后果,必须用大量的人力来拓宽道路。相反,地铁列车有着更多的优势。除了建设地铁的难度和高成本外,在许多方面它都优于公共汽车。
Taking the advantages and disadvantages together into consideration,I would be in favor of developing the subway train as soon as possible.
把优点和缺点一起考虑,我会赞成尽快发展地铁。
