Jim has ______________ the Party for two years. join been in take part in/join in take part in/join in join 第5题中，Party首字母大写表示“党”，而非“聚会”，“入党”是参加组织，应该用join, 但此题有时间状语“for two years”表示一段时间。join 属于短暂性动词，不能与时间段连用，故需要使用其延续性动词be in（表状态，能与时间段连用）。此题也可以用be a member of 代替。 Jim has ______________________ the Party for two years. been a member of 附加题1：Her father joined the Party last year. （同义替换） A. entered B. came into C. became a member of D. took part in C 解析：此题表示“入党”，加入组织，而非活动，排除D答案，A和B是干扰项。可选用join/be in/be a member of, 由于时间状语是last year,不是段时间，可以用短暂性动词become 代替延续性动词be。 附加题2：We went to ____ Kangkang’s birthday party last Friday.

A、C、D都不是省略to的不定式，故选择不填，使用make sb.+adj.结构。 C B 5. Though I had no time to travel, I still felt very happy. 虽然我没有时间去旅行，但是我仍然感到很开心。 （1）though为连词，意为“虽然，尽管，即使”，引导让步状语从句。不能与but连用，相当于although/even though/even if. eg.
