题型：不详难度：来源：
______ smoking, he would not have got cancer in the lung.| A．Was he given up | B．Had he given up | | C．Did he give | D．If he gave up |
|
答案
| B |
解析
| 是因为时态前后有矛盾。由于主句谓语是would not have got，这表明是对过去事实作出的假设，所以从句谓语应该是 had given up，而不是像D项那样用一般过去时。另外，当虚拟条件句中有 had, should, were 等词时，通常可以省略 if，并将 had, should, were 提前置于句首。 |
