Question

问一道英语题

we must know what we should do and what we should avoid _____a good impression on others in public place. 答案是to leave 但是avoid不是没有to的用法吗。不是doing吗

Answer 1

你理解错句子结构了。“what we should do and what we should avoid ”在这是整体，作为“know”的并列宾语，是“我们应该做和应该避免的（事）”，“to+.."在这是表目的，整句话“我们必须知道什么是我们应该做的，什么应避免，以便给公众留下一个好印象” 补充：avoid后+n/doing

Answer 2

把句子这样分你看看你能不能理解: we must know (((what we should do and what we should avoid)))) _____a good impression on others in public place. 这样的话就必须用TO DO 啦。

Answer 3

what we should do and what we should avoid 是并列的两个宾语从句而to leave a good impression on others in public 整个不定式短语作目的状语。

Answer 4

答案错了 avoid leaving
