18、 Some pictures of the river brought the days back to the old ________ they swam in it.

A. when B. that

C. who D. where

【解析】

16、D.

由于先行词是前面整个句子，且在从句中作主语，所以用which。of course是插入语。

17、D.

将疑问句改为陈述句：this research center is…明显短少先行词，有必要加上代词the one来作先行词，又因定语从句不缺主语或宾语，所以用联系副词where。假若在this后加the，就选where，请想想这是为什么。

18、A.

由于先行词是the days，并在定语从句中作状语。
