解题思路： 如下
解题过程：

　　C. to find 　　　　　　　D. for finding
　　5. The person we spoke to ______ no answer at first.
　　A. making 　B. makes 　C. make 　D. made
答案及辨析：
　　1.此题中包含固定短语devote…to，其中to为介词，后面应接动名词。动词devote后接的宾语为all，all又为先行词，后又包含一个定语从句he could (do)。此题很容易以为could后应接动词原形；而误选A项。答案为D项。
　　2.此题应该首先把句子结构分析清楚。句中Everything既作句子的主语，又作先行词，后接定语从句(that) he had，而had been taken是过去完成时的被动形式作句子的谓语。此题意为：在他返回家乡之前，他所有的一切都被拿走了。故选C项。
　　3．此题中包含句型结构spend…(in) doing sth，其中题申spent的宾语为much time，much time作为先行词，后又接定语从句he could (spend)。故选A项。
　　4．题中difficulty为先行词，后接定语从句(that) I have，构成固定句型：have difficulty (in) doing sth。因为in可以省略，所以选B项。
　　5．此题中也包含一个定语从句we spoke tO，the person既作先行词，又作句子的主语，横线处应填人的是句子的谓语，根据句子的需要，应用过去时。本题中的to为陷阱，实际上它属于定语从句，而不影响主句的谓语动词。故D项正确。
最终答案：略
