谢了!

Answer 1

1 D， 前半句的同样意思的 主宾语颠倒而已。 前面是 it took him, 倒过来，自然是 him 被 it 给took 即 he was taken啦

2 C， 定语从句， 首先 埃菲尔 铁塔的 埃菲尔在后句 金属框架里面作主语，所以 a 不能选， whom是宾格； which不能指代人，也排除； whose是所有格，谁的，显然也排除，所以是C.

Answer 2

A.

我觉得是宾语前置。

C.
这是强调句型。

（It was）Eiffel (who/that) constructed the metal framework.
这是Eiffel 建造的金属构架。

O(∩_∩)O~

Answer 3

D（宾语从句：引导词+主语+谓语+……，故排除B与C， 而根据前句时态用过去时）
C (强调句WHO 作主语）
