问题描述：
Their problem today is somewhat similar to ___ they faced many years ago. A. that B. which
C. that which D. it
为什么不是A而是C
填A语法分析应该是正确的
答
因为如果选D,那they faced 后面就缺少宾语。
similar to 的to 是介词，后面应该接宾语，则空格到结束这一段是个宾语从句，而这整句是个定语从句，故选C
答
没这种用法，只有to+不定代词才行。
答
答案选择C.原因：当一个句子的前面出现的名词,在后面再次出现可用代词that(单数）,如果后面直接接定语从句不太合适,因此应用which（因前面有了that)来引导该定语从句.
