(答案→)who---whom 解析：【小题1】who---whom 考查非限制性定语从句的关系词。此处作介词的宾语用whom；【小题2】find---finding 考查have difficulty （in）doing sth的用法。此处in被省略，故将find改为finding； 【小题3】outdoors--- outdoor 考查名词作定语。名词作定语一般用名词的单数形式；【小题4】stopping--- stop考查persuade的用法。这里persuade后接不定式作宾补，故用stop的形式；【小题5】made后加to 考查被动语态的用法。此处原句改为：we should make children understand the importance of saving water.改为被动语态后需要带上to；【小题6】he前加that 考查强调句型。此处not until I came back是被强调的部分；【小题7】base---based 考查过去分词短语作定语。此处相当于定语从句which are based on. . .；【小题8】go--- going考查prefer的用法，此处prefer to 中的to是介词，后接动名词；【小题9】去掉of 考查介词的用法。此处he didn’t do well in it before.是句子，故去掉of；【小题10】去掉one或去掉a考查代词和冠词的用法。此处去掉one是as引导的定语从句，先行词有such修饰。
