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
3.should在这里是应当的意思.should 在句子做应当的意思,为主动时,表示谦逊或者建议等等礼貌的意思.这里句子的意思是,司机应该远离喝酒,也就是司机禁止喝酒,所以如果用should 就应该用被动语态,便是被禁止的意思.
4.A.far enough 固定用法.B 没有much far 只有much farther.Csuch 是指定,特定的意思,句意不符.D.that 就是指代那是走了的距离,意思就是说走可那么远,佐治不想回头.
5.A.指代人,复数
6.how much 表示程度.你不知道我多想再见到你.
how long 提问的是距离
