2020年成人學士英語備考之短文挑錯專項輔導一
Dinosaurs, saber-tooth tigers and the dodo bird are famous examples __1__ of animals that have become extinct. In case of the dinosaurs, it __2__ seems likely that a catastrophic event alters the global climate __3__ enough to lead to their disappearance. More recent extinctions and near-extinctions-such as the blue whales, tiger, panda, and __4__ North American bison—have been the direct result of human activity. By the early 1990s, species were becoming extinct at a rate of three per hour, or 27,000 every day – a figure quoted by the American biologist Edward O.Wilson of Harvard University, based on his most conservative estimates. This rate of extinctions carries with it some terrible consequences. Each plant that becomes extinct,for example, may take with it as much as 30 insects and animals __5__ that depend on it for food. Habitat loss is one of the most important causes of extinction. For rising populations in many countries __6__ lead to the clearing of more land, habitats such as raining forest __7__ and grasslands disappear.
In the East Africa, once renowned for its wildlife, few wild animals __8__ remain living outside the boundaries of national parks and game __9__ reserves. In other parts of the world, coastal ecosystems are clearing __10__ for development. Wetland areas are drying out as a result of water extraction to support farming and tourism. Bird species are among the worst affected by the loss of wetlands.
答案：
1.saber-tooth—saber-toothed。如果是“形容詞+名詞”作前置修飾語，那么名詞要加-ed。
2.^case—the。in case of 和 in the case of 的意思是不同的，前者的意思是“萬一”，后者的意思是“在……的情況中”
3.alters—altered。這里談的是恐龍滅絕的時期，所以時間是過去。
4.whales—whale。定冠詞+可數名詞的復數 是特指，所以the blue whales是特指，但是上下文并沒有提及特定的藍鯨，所以從整個句子的意思來看，這里是指物種，是類指，所以應該用“定冠詞+可數名詞單數”形式。
5.much—many。insects and animals 是可數名詞，所以應該說as many as
6.For-- As/Since。盡管for作為連詞可以引導原因狀語分句，但是它一般不放在句首。
7.raining—rain。rain forest,指熱帶雨林
8.the去掉。East Africa是專有名詞。
9.living—alive。remain是系動詞，后面的形容詞是主語補足語，living不能作主語補足語。
10.clearing—cleared。這里需要用被動語態
