19.A keep ...from...阻止....(此句中noise作主语,故用被动语态)(if主将从现)
20.D (have sth done 让...被... add up加起来)(add up to 加起来总计...)
22.only +after(时间状语从句)置于名首时,句子要倒装。(前半句中已使用了had done ,故后半句应用过去时)
23.be cared for被照顾
24.spare 腾出,空出(又如:I can spare no time)
26. (搭配是present at 出席 absent from缺席)回答人数多少时用(large 、small)
27. (A B都表示被劝告,而D表示被说服)题目中回答已经不抽烟了。
28. The news [that(that引导同位语从句,表示消息的内容)he tripped over a stone hurt himself] travels(谓语动词)....
又如:the Moon travels around the Earth.
29. There is no doubt that 固定句型,毫无疑问......(in the end at the end of by the end of )
