易错句子Last night the crew reef the sails before the gale hit.
正确表达Last night the crew reefed the sails before the gale hit.
汉语动词没有时态变化,而英语要用过去式表示过去发生的动作。时间状语 Last night 说明动作发生在过去,因此须用 reef 的过去式 reefed(reef 的过去式与过去分词同形)。

易错句子The sails reefed quickly when the wind rose.
正确表达The crew reefed the sails quickly when the wind rose.
reef 是及物动词,必须带宾语,即“被收小的帆”。汉语可以有“帆收起来了”这类受事主语句,但英语中帆不能自己 reef,须补出施事主语(the crew)并保留宾语(the sails)。

易错句子The crew had to reef sail as the wind grew stronger.
正确表达The crew had to reef the sails as the wind grew stronger.
汉语“收帆”是动宾式复合词,宾语前不加冠词;此处 sail 指具体的帆,是可数名词,单数前必须有限定词,泛指时用复数,故应说 reef the sails(或 reef the sail),不能光用 sail。
