　　答案及解析:
　　1.saber-tooth—saber-toothed
　　如果是“形容词+名词”作前置修饰语，那么名词要加-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“万一”，后者的意思是“在……的情况中”
　　3.alters—altered
　　这里谈的是恐龙灭绝的时期，所以时间是过去。
　　4.whales—whale
　　定冠词＋可数名词的复数是特指，所以the blue whales是特指，但是上下文并没有提及特定的蓝鲸，所以从整个句子的意思来看，这里是指物种，是类指，所以应该用“定冠词＋可数名词单数”形式。
　　5.much—many
　　insects and animals 是可数名词，所以应该说as many as
　　6.For-- As/Since
　　尽管for作为连词可以引导原因状语分句，但是它一般不放在句首。
　　7.raining—rain
　　rain forest,指热带雨林
　　8.the去掉
　　East Africa是专有名词。
　　9.living—alive
　　remain是系动词，后面的形容词是主语补足语，living不能作主语补足语。
　　10.clearing—cleared
　　这里需要用被动语态。
