Question

The 29th Olympic Games，（ ）in Beijing in 2008，was a great success．

A．held B．which held C．tobe held D．was held

这一题为什么选择A啊，这考察的是什么语法现象，到底怎么做呢？

Answer 1

答案是A held
The 29th Olympic Games，（held）in Beijing in 2008，was a great success．
译：2008年在北京举办的29届奥运会取得了极大的成功。

这题考查的是定语从句。held in Beijing in 2008是作为定语修饰The 29th Olympic Games，只不过这里省略了Which was而已，所以完整的句子应该是：The 29th Olympic Games，（which was) held in Beijing in 2008，was a great success．

在定语从句中经常会出现省略的情况，比如：The letter （which was）sent out yesterday was received by my girlfriend today. 这里为了使句子更加简洁，通常会省略which was.

这题的答案也可以是which was held，当然一道题中不可能出现两个正确答案。

满意的话，记得采纳咯~

Answer 2

答案是which was held或者held, 所有只有A是对的。
