【考研英語(yǔ)高分寫作】PartB歷年真題范文
Directions: Your essay should cover these three points: 1. Effect of the countrys growing human population on its wildlife. 2. Possible reason for the effect. 3. Your suggestion for wild life protection.
As is shown by the two graphs, the U.S. population soared from 2 million to 250 million from 1800 to 1990. In contrast, the number of wildlife species no longer existing shot up, adding up to 70 over the same period of time. It is obvious that the extinction of wildlife resulted from the population explosion. We may cite a variety of reasons for this situation. First of all, the destruction of ecological balance plays a pushing role. Due to population problems, pollution and desertification are becomeing increasingly serious. Furthermore, a great number of species were killed for food, for money and even for fun. Even worse, with the rapid growth of human population, inhabitable areas were expanding so fast that few areas were left for wild animals. To sum up, it is imperative for us to take effective measures to protect wildlife. Firstly, the U.S. government should pour more investment into wildlife protection in a bid to create a better environment. Secondly, the birth rate in the U.S. must be put under control as the dramatically expanding population gives rise to serious environmental problems.
如圖所示，從1800年到1990年，美國(guó)人口從200萬猛增到2.5億。與此相反，滅絕的野生物鐘數(shù)也直線上升，在同期增加到70種。顯而易見，野生動(dòng)物的滅絕源于人口劇增。 我們可以引用很多原因解釋此現(xiàn)象。首先，生態(tài)平衡的破壞發(fā)揮了主導(dǎo)作用。由于人口問題，污染和沙漠化日漸嚴(yán)重。其次，很多物種由于捕食、盈利甚至娛樂而被獵殺。更糟糕的是，由于人口急劇增長(zhǎng)，人類居住地?cái)U(kuò)張如此迅速，以至于野生動(dòng)物無家可歸。 總而言之，我們很有必要采取有效措施保護(hù)野生動(dòng)物。首先，美國(guó)政府應(yīng)向野生動(dòng)物保護(hù)投入更多資金以便改善環(huán)境。其次，由于人口激增導(dǎo)致了嚴(yán)重的環(huán)境問題，美國(guó)人口出生率必須得到控制。
