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.
