答案详解

1.[C]【解析】虚拟语气。It's (high/about/the right) time +that从句，从句中谓语动词一般用过去时。因此答案选C项。句意：已经5点了，我们该回家了。

2.[B]【解析】固定搭配“can't...too+adj./adv.”意为“无论……都不为过”。因此答案选B项。句意：这本书我怎么推荐都不为过，因为它确实对英语学习很有帮助。

3.[A]【解析】only+to do sth.作结果状语。选项B中不定式多作目的状语，选项C中现在分词多作原因和伴随状语。因此答案选A项。句意:他匆匆忙忙地走进教室，结果发现里面空无一人。

4.[B]【解析】副词近义词辨析。continuously强调持续不断；continually强调一段时间内多次发生，时断时续；constantly侧重于事件发生的稳定，持续，经久不变；considerably指程度或数量上多。因此答案选B项。句意：这个孩子不停地在课堂上捣乱，使得老师很生气。

5.[A]【解析】介词与名词固定搭配。on my own意为“独自，独立地”；by my own没有这种表达方式；of my own意为“属于我自己”；for my own意为“为我自己”。因此答案选A项。句意：我得让人来帮忙，我自己无法完成这个工作。
