题目内容
11．I have already finished reading the novel．But my classmate hasn't finished it ．（ ）| A． | already | B． | yet | C． | yesterday | D． | just now |
分析 我已经读完了这本小说，但是我的同班同学们还没有读完．
解答 答案：B
根据I have already finished reading the novel可知，动作已经完成对现在造成一定的影响，所以用现在完成时态，现在完成时态的结构为have/has+动词的过去分词．又因为But my classmate hasn't finished it可知，此句是一个否定句，所以应该用yet表示"还，仍旧"，故选B．
点评 判断动词的时态，要通过所给的时间状语、提示词或语境去判断动词存在的状态．注意容易混的副词的用法．already用在肯定句中，yet用在否定句和疑问句中．
