razors

易错句子He razors every morning before work.

正确表达He razors his beard every morning before work.

razor 作动词是及物动词，后面必须跟宾语，指明剃的部位或毛发。汉语的“剃”可以不带宾语（如“他每天早上剃”），但英语不能省略宾语，所以必须补出 his beard。

易错句子He razored on his chin carefully.

正确表达He razored his chin carefully.

razor 是及物动词，被剃的部位直接作宾语，不需要介词。汉语说“在下巴上剃”，这个“在……上”不能直译成 on，否则句子不合英语动词的搭配。

易错句子After razor his beard, he washed his face.

正确表达After razoring his beard, he washed his face.

after 在此是介词，后面接动词要用动名词形式 razoring，不能用原形。汉语“剃完胡子后”没有词形变化，学习者容易把原形直接放在介词后。
