第一问：
当名词前有形容词最高级,数词以及the last等修饰,后面要用动词不定式作定语.
句意：乔是最后一个离开教室的人,
第二问：
v-ing 形式在这里作状语,表示时间,其与句子的主语 Jack 之间是逻辑上的主谓关系,因而要用现分.原句相当于：When he was finding the answer to the question,Jack surfed the internet for an hour.
句意：在寻找问题的答案时,杰在网上搜了一个小时.
to leave表示还没离开
加ing，是因为它是状语而不是独立的完整结构，所以要么是to find, 要么是finding。to find表示可能还没找到（是在过去某个时刻还没找到），finding表示已经找到。
