题目内容
7.Linda a lot since she entered Harvard University.( )| A. | change | B. | has changed | C. | will change | D. | changed |
分析 Linda自从进入哈佛大学以后改变了许多.
解答 答案:B.
根据since she entered Harvard University可知,"自从进入哈佛大学以后"表示一段时间,表示过去的动作一直持续到现在,应该用现在完成时态;现在完成时态的结构为have/has+动词的过去分词,排除ACD,故选B.
点评 本题主要考查了现在完成时的用法.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.
