动词时态
II．例题
例1 I learned that her father ____ in 1950.
A had died B died C dead D is dead
解析：该题正确答案为B。从句中的谓语动词动作虽然发生在主句谓语动词的动作之前，但因从句中有明确的过去时间状语in 1950, 所以不用过去完成时态，而用一般过去时态。
例2 The five-year-old girl ____ by her parents.
A is looked B has looked for
C is being looked for D has been looked
解析：该题正确答案为C。在带有介词的动词短语用于被动语态句中，介词不能省，否则就变成了不及物动词短语，而不能用于被动语态的句子中。
