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 forc 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。
