答案详解

1.[A]【解析】将来完成时由“shall/will+have+动词的过去分词”组成，表示在将来的某个时间已经发生的事情。

2.[D]【解析】It is important/necessary/natural/strange等结构的主语从句，谓语动词要用虚拟语气，形式为动词原形或should+动词原形。

3.[C]【解析】关系代词which指代先行词the tree，树枝和树为所属关系，用介词of。the branch of which可以用whosebranches代替。

4.[C]【解析】这里是现在分词独立主格结构，且分词所表示的动作在谓语动词之前发生，所以要用现在分词的完成时态。

5.[B]【解析】本句为完整的there be句型，空格后是不定式短语作定语修饰electronic application，than表示更高级比较。
