recommend

1.recommend往往有双宾语。例如：Can you recommend me an English dictionary?

2.I recommend the reader to be on the lookout for idioms等句子里偶尔在recommend后面加上to，但很不普通，加上it to也可以，比只加上to普通。

3.recommend后面接动名词，不接不定式，如可以说I recommend being on the lookout for idioms，不可说I recommend to be on the lookout for idioms。

4.recommend后面可以接以that引导的从句，从句里用虚拟现在式。例如：I recommend that the reader be（不用is）on the lookout for idioms.和I recommended that the reader be（不用was）on the lookout for idioms.

5.He recommended the new book to us和He recommended us to the new book意思相同，第一句比第二句普通。

6.在口语里有时把recommend用作名词，作recommendation解。例如：Did he give you a recommendation for the post?这用法主要用在美国。
