题目内容
1.-Why is Mr.Yang still in the teachers'office?-Maybe he his work yet.( )
| A. | doesn't finish | B. | hasn't finished | ||
| C. | haven't finished |
分析 --杨老师为什么还在办公室里?
--也许他还没有完成他的工作.
解答 答案:B
根据句意"杨老师为什么还在办公室里?"和"yet"可知,这里的时态应为现在完成时,且这里为否定形式.现在完成时的构成为have/has+过去分词,主语为三单"he"所以这里应该用has,所以这里应填词语为hasn't finished,答案为B
点评 做这样的题时要根据句中的现有词语,确定句子的时态,然后根据时态的构成选出正确的选项.
