问题     40年前,黄河人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,主要河流人海口,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。

选项

答案     Forty years ago, the area around the Yellow River estuary was a heaven for birds. With the lessening volume of river water and land reclamation in the delta area, however, wetland coverage here has been greatly reduced, so has the number of birds visiting the area. In recent years, the ecological system of the Yellow River Delta wetland has significantly improved. Every year nearly 1 million birds escape the winter and stay here, among which many are rare species in the world. Conservation of the Yellow River Delta wetland is only one successful example of China’s wetland protection effort. It indicates that great strides has been made in this field.
    Up to now, China has built 353 wetland natural preservation zones. The establishment of these zones has also protected headstreams of China’s big rivers, estuaries of main rivers and migratory birds’ breeding places and winter-escape habitats.
    At present, wetland protection still remains to be a weak link in China’s overall ecological improvement. The Chinese government will take effective measures to stop activities of predatory exploitation of wetland resources to guarantee their sustainable utilization.
