joe is the last person to leave the classroom,为什么要用to leave?Finding the answer to the quesFinding the answer to the question ,jack surfed the internet for an hour 我知道这是前面那个是状语,但不理解,请讲解,为么加ing形
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。
