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(yǔ),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(wàn)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(shí)期,所以時(shí)間是過(guò)去。
4. whales—whale
定冠詞+可數(shù)名詞的復(fù)數(shù) 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(lán)鯨,所以從整個(gè)句子的意思來(lái)看,這里是指物種,是類指,所以應(yīng)該用“定冠詞+可數(shù)名詞單數(shù)”形式。
5. much—many
insects and animals 是可數(shù)名詞,所以應(yīng)該說(shuō)as many as。
6. For—As/Since
盡管for作為連詞可以引導(dǎo)原因狀語(yǔ)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(dòng)詞,后面的形容詞是主語(yǔ)補(bǔ)足語(yǔ),living不能作主語(yǔ)補(bǔ)足語(yǔ)。
10. clearing—cleared
這里需要用被動(dòng)語(yǔ)態(tài)。
