高二英语的问题1.Sales of CDs have greatly increased since the early1990s,when people_____to enjoy the advantages of this new technology.这道题答案是began,但答案为什么不是had begun呢?2.过去完成进行时和过去完成时怎
1,因为题目上说了since the early 1990s,说了具体时间,用过去式.
2,过去完成进行时,是说明从过去到过去某个时间一直在做的事,had been doing sth.；过去完成时,是说明在过去已经完成的事,had done sth.
3,他保持看着她,好奇是否以前在哪见到过.选D,因为前面是过去式,说明在那之前看到过她就要用过去完成时.
4,他是这个村里所以女孩中唯一一个有很好报酬的人.选A,be well paid是固定的好的报酬的说法.
5,最后一个到的为这顿饭付账.选C,考察非谓语动词,所以用to arrive.
回答完毕.
看我这么精心回答,给分吧,如果能追加更好噢：）15少了点.哈哈.
