题目内容
4.He ________ another career,but at the time he didn't have enough money to attend graduate school.( )A. | might choose | B. | might have chosen | ||
C. | should have chosen | D. | could choose |
分析 他有可能已经选择了另一个事业,但是那时候他没有足够的钱上大学.
解答 答案:B
解析:A:或许选择(一般过去时);B:可能已经选择了(对过去的虚拟);C:本应该选择(而实际未选择);D:可能选择(一般过去时).根据后面的"但是那时候他没有足够的钱上大学"可知前面句子是对过去的虚拟,故A、D选项直接排除;C选项代入原句后不符合句意,故排除(因为是没钱这一客观原因使得他未能选择另一事业,而并非自己主观不选);B选项代入原句符合句意.综上,本题答案为B选项.
点评 本题考查情态动词的辨析,做此类题目时一定要清楚各个选项的含义及用法,再结合句意及其它要求确定最终的答案.
