来源:百度知道 编辑:UC知道 时间:2024/06/28 11:07:46
people ran away to escape the tiger_____it was seen,
有四个选项,我选的是as,答案是wherever

Pumas never attack a human being except_____cornerned.
我选的being,答案是when they are

The experts were now fully convinced that the animal_____a puma
我选的must be,答案是could only have been

能帮我分别解释一下吗?谢谢了

1、答案wherever的意思是无论 在哪里的意思。
2、being 主语应该是pumas 这样从句的主语和主句的主语一样的话,从句的主语可以省略。但是根据意思肯定不应该选择being。
3、前面肯定进行了很多对这个动物的推测,是这个吗,是那个吗,但是都不是,只有应该是,所以选择could only have been

这是NEC(3)第一课的内容
people ran away to escape the tiger_____it was seen
答案是wherever 意思是讲无论在哪里看见老虎,人们就会逃离.
Pumas never attack a human being except_____cornerned.
答案是when they are 意思是讲美洲虎不会袭击人类除非当它们被逼地走投无路.

The experts were now fully convinced that the animal_____a puma
答案是could only have been
应该用过去完成时,仍然表示一种猜测

people ran away to escape the tiger_____it was seen,
有四个选项,我选的是as,答案是wherever
翻译:人们不管在哪遇见老虎都会逃命
WHEREEVER 无论在哪

后两个是新概念第三册的原文lesson1 puma at large
1 如果用as是定语从句,显然不对,因为as可以提到句首。
