1、备考中考英语常考易错点专题二十 词汇运用专题二十 词汇运用易错清单一、 考点分析词汇运用试题主要是考查学生对单词的拼写能力、词形变化和语法知识运用以及词组辨别能力等。试题通常以语篇、对话或句子的形式出现,测试内容以实词为主,虚词很少。这一题型中所给的词几乎覆盖了所有的词性,比如名词、动词、形容词、数词、量词、代词、副词等。填空时要考虑名词的单复数、动词的第三人称单数、现在分词、过去分词;形容词、副词的比较等级;数词的基数词、序数词等。测试题型可以归为两大类:单词拼写和词形填空。其中单词拼写一般有两种题型:根据句意及首字母提示填写所缺单词;根据句意及汉语提示填写所缺单词。词形填空也包括两种题型:

2、用所给词的适当形式填空;选词并用其适当形式填空。二、 构词法英语构词方法主要有三种:即合成、派生和转化。(一)转化英语单词的词性非常活跃,名词用作动词,动词转化为名词,形容词用作动词等现象非常普遍,这种把一种词性用作另一种词性的方式就叫做词性的转化。阅读中经常出现转化词,只要抓住单词的原始意思,结合句子成分,就容易弄清它们的引申义。1. 动词和名词之间的相互转化。有时意思变化不大,有时有一定的变化。1)动词转化为名词。如:Shall we go out for a drive next Sunday? 下个星期天咱们出去驱车旅行,好吗?句中的drive由动词转化为名词(词意引申为“驱车旅行”)

3、。如:I often go there for a walk. 我经常去那里散步。(句中walk由动词转化为名词)2)名词转化为动词。如:Have you booked your ticket? 你的票订好了吗?(句中book由名词转化为动词,词意引申为“订购”)Hand me your knife, please. 请把你的刀子递给我。(句中hand由名词转化为动词,词意引申为“传递”)2. 少部分形容词转化为动词。如:The train slowed down to half its speed. 火车速度减慢了一半。(句中slow由形容词转化为动词,词意引申为“减速”)Dont dirt

4、y your clothes. 别把你的衣服弄脏了。(句中dirty由形容词转化为动词,词意引申为“弄脏”)3. 形容词和名词之间的相互转化。如:The poor were not allowed to go into this park those days. 那个时候,穷人是不允许进入这个公园的。(句中poor由形容词转化为名词,词意引申为“穷人”)They took the sick to hospital yesterday. 昨天他们把那个病人送进了医院。(句中sick由形容词转化为名词,词意引申为“病人”)4. 有些词可以词形不变,只因重音变化而发生词类转化,有时词义也可能变化。如

5、:record rekd v. 记录record rkd n. 记录5. 有些词词形不变,只因词尾的清浊音变化而发生词类转化,有时词形也可以变化。如:excuse kskjuz v. 原谅excuse kskjus n. 原谅use juz v. 用use jus n. 用(二)派生派生词是在一个单词前面加前缀或后面加后缀构成新词。如:happyunhappy(加前缀un-)happyhappily(加后缀-ly)1. 通过加前缀构成另一个词。前缀一般不造成词类的转换,但能引起词义的变化。前缀中有相当一部分可构成反义词。常用的前缀有:前缀意义例词dis- 不,相反的dislike, disap

6、pear, dishonestim- 不impossible, impolitemis- 错误的misuse, misunderstand, mistrustre- 重新,再次rewrite, retellsuper- 超级,上层supermarket, supermantele- 远telephone, telegram, televisionun- 不unfair, unusual, unable, unlikeunder-下面的underground, undergraduate个别前缀也可以引起词类的变化,如:en-可以和名词或形容词构成动词:enlarge, enable, enco

7、urage; a-可以和名词构成形容词:asleep, aboard, aside; out-可以和一些动词构成名词:outcome, outlet, outlook。2. 通过加后缀构成另一个词。后缀不仅能改变词义,也能改变词类。1)常用的构成名词的后缀:后缀意义例词-er 人,动作者worker, singer, recorder, teacher-or 人,动作者actor, visitor, editor-ist 人,主义者chemist, dentist, scientist,-ess 女性actress, waitress-hood身份,状态childhood, boyhood-m

9、y3)常用的构成副词的后缀:后缀意义例词-ly 副词词尾slowly, happily, simply-ward(s)副词词尾eastward(s), backward(s)4)常用的构成形容词的后缀:后缀意义例词-able的agreeable, payable, readable-an 的European, American, Canadian-al 的political, musical-en 由制成woolen, golden-ed的blue-eyed-ful 充满的careful, painful, hopeful-ish 的foolish, Swedish-less 没有的carel
