1.B 后句意思是我必须要走了,可知前句应为“应经7点了”.only意为只有,already意为已经,yet用在否定句中意为还没,just意为刚刚.遂选B already.
2.D Peter在吗?不在,但是,他现在（ ）在这里.他又迟到了.由句意可知此处应填应该.would是will的过去式,用在此处不妥.may可能,must必须,should应该.
3.A see/hear sb do sth,或see/hear sb doing sth.前者表示看到/听到某人做某事,后者表示 看到/听到某人正在做某事,强调看到了全过程.所以此处不是sing就是 singing,没有另外三种说法.
1.B 2.D 3.A
1.B. 我必须得走了，说明他很急，所以是已经7点了。
2.D.这个时间他应该在这，但是他又迟到了。
3.A. hear sb do。
1.B 2.D.3.A
1、B，already是已经的意思，yet是还没的意思，only和just是只不过的意思，根据I have to go now可推测出是already.
2、D，他现在应该在这的。根据说话的语气判断，should最好。
3、hear sb. do sth.或者hear sb. doing sth.,根据排除法，排除掉BCD，选A。
