6.—I have got a headache.
—No wonder.You_________ in front of that computer too long.(2007江西)
A.work B.are working C.have been working \x05\x05D.worked
怎么选为什么

Answer 1

C
work和are working是一般现在时和斗和现在进行时,只说明了现在的情况,而未包含过去的,故排除A和B；而worked只说明了过去,未包含现在,故排除D,只链中有C用了现在完成进行时,既包含了现空唤盯在,又包含了过去,说明了动作对现在的影响是你头痛了,是正确的.
