1.从句子看,缺失部分是一个时间性质的词语.如果是A.since后面是过去式,前面是过去完成时,剔除选项.B,as 是当的意思,前后应保持时态一致.剔除.C,在他上大学之前我没有见过他.符合.D.when是当……的时候……强调同时进行的,所以事态也应该一致.
2.句意为:假如汤姆从美国回来需要很长时间.那么A,在汤姆回来时前是很长的时间,是对的.B.当汤姆回来,是很长的时间.句意不通.当作为疑问词存在,不可能出现未来时,所以不符合.C同B ,DIt,本身指代汤姆从美国回来,that做定语代替a long time 语法不通

5.A.指代人,复数

3.被动语态(be)所以是should be kept
4.A、C就肯定是错的了,排除发不可能有much的用法就选D
5.选A
6.选A的话你不知道我是多么希望再次见到你。
选B的话你不知道多久我想再次见到你。(不通)选A其他的不...
