问题
She ought to stop work; she has a headache because she ______ too long.
选项
A、has been reading
B、had read
C、is reading
D、read
答案
A
解析
根据主句的时态,我们可以将B 和D 排除。由于这里要表达“她现在头疼”是“过去一直看书的结果”,强调的是过去对现在的“影响”,因此要使用现在完成时。A 为正确答案。例如:I have been puzzling my brains about this question for weeks now.对这个问题我已经苦苦思索了几个星期。I have been corresponding with him ever since I got to know him.自从认识他以来,我就一直与他通信。
