48.B
【解析】句意:该公司宣布,由于越来越多的人选择阅读电子书,明年将关闭三分之一的书店。A:will close将关闭,一般将来时;B:would close过去将来时;C:will open将打开,D:would open将打开,过去将来时。根据空格后the next year,明年,可知时态为将来时,结合主句announced为过去式,可知句子时态为过去将来时,结构为would do,排除A和C。结合句子more people chose to read e-books. 更多的人选择阅读电子书。可知此处是指关闭三分之一的书店,应用would close,故选B。
【点评】考查动词的时态,注意识记过去将来时would do的用法。
49.D
【解析】句意:亚历克斯说下周末他要去乡下看望他的叔叔。A现在完成时,B现在进行时,C一般将来时,D过去将来时,宾语从句谓语是said,时态是一般过去时,从句时间状语是next weekend是将来时标志,故从句时态是过去将来时,故选D。
【点评】考查宾语从句的时态,注意识记过去将来时的用法。
50.D
【解析】句意:—— 爱丽丝前天回家了。——真的吗?她去哪里了?have gone表示去了某个地方,但没有回来;have been表示去过某地,且现在已经不在那个地方。根据时间状语 the day before yesterday 可知,此句用过去完成时,结构为"had done",排除AB;此处表示已经回来了,用had been。故选D。
【点评】考查时态,注意过去完成时和have been的用法。
