单词的用法及固定搭配

That letter from the writer is recommendation enough是“那作家写的那封信作为推荐足够了（不必要其他推荐了）。”

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

recollect作“回想到”或“记得起”解，不是单纯的“记得”，是有意志的动作，如说“我记得他的名字”不可说I recollect his name，该把recollect改作remember。

recognize在一般英汉词典里注作“认识”，实际是“见了某人而认出（他）”，是一时的动作。

I reckon on（或upon）hearing from him before long等句子里的reckon on（或upon）作“信赖”解

参见recitation

recitation在英国作“背诵”解，必须背出声来，“默诵”并不是recitation。

on a recent day，on a recent morning，on a recent night等表达方式不合习惯，该说the other day，the other morning，the other night等。

receive是一时的动作，所以不可说I have received your letter (for) five days，该说I received your letter five days ago或It is five days since I received your letter。

on（或upon）(the) receipt of（一收到了…立刻）里的the可有可无。

recall（动词）后面接动名词，不接不定式，如可以说I recall meeting him somewhere，不可说I recall to meet him somewhere。把meeting改作having met意思不变。

for business reasons，for health reasons，for political reasons等表达方式里该用复数形式reasons。
