  • Remain 用法探究

    remain 是高二册第2单元的重点动词,同时也是高考考点.历届高考,总有一些考生对remain一词的用法模糊,错选了答案.下面就remain作动词时的用法进行总结说明,大家一起来看看.

    一、作不及物动词用

    1.表示“剩下”、“仍有”,只能用于主动语态,不可直接跟宾语.例如:

    ①They had all those that remained.他们把剩下的全部拿走了.

    ②This visit willalways remain in my memory.这次拜访将永远留在我的记忆之中.

    2.表示“留下”、“逗留”,特指在他人走后留下.例如:

    ①They went,but I remained.他们走了,但我留了下来.

    ②I shall remain here all the winter.整个冬天我将留在这里.

    3.表示“尚待”、“留待”,后面接被动语态的动词不定式.例如:

    ①One problem remains to be solved.有一个问题尚待解决.

    ②That remains to be proved.那尚待证实.

    二、作系动词用

    表示“一直保持”、“仍然(处于某种状态)”、“继续存在”、“依然”.

    1.后面接名词作表语.例如:

    ①Language was,is and will remain the chief means of exchange of ideas.语言,过去、现在和将来依然是交流思想的主要工具.

    ②In spite of their quarrel,they remained the best friends.他们尽管吵过架,却仍不失为最好的朋友.

    2.后面接形容词作表语.例如:

    ①We must always remain modest and prudent.我们必须经常保持谦虚、谨慎.

    ②Despite the danger,she re- mained calm.尽管危险,可她依然镇定自若.

    3.后面接介词短语作表语.例如:

    Victories remain with us.胜利属于我们.

    4.后面接V-ing作表语.例如:

    She remained standing though we repeatedly asked her to sit down.虽然我们三番五次地请她坐下,她还是站着.

    5.后面接过去分词作表语.例如:

    ①The true author of the book remains unknown.这本书真正的作者依然不详.

    ②The situation remains unchanged.局势依然未变.

    require 有两种用法:
