1、中考英语词汇知识精讲中考英语词汇知识精讲重点、难点、考点一、重点是：(1)常见的构词法1)合成词：合成词是由两个或两个以上的词构成一个新的词。如：blackboard(黑板)，newspaper(报纸)，afternoon(下午) ,pencil-box(铅笔盒)。2)派生词：派生词是由词根加派生词缀构成的词，词根是派生词的基础，同一词根加不同的派生词缀可以表示不同的意义，还可以表示不同的词的词性。动词变名词：后缀er drive(驾驶)driver(驾驶员) teach(教)teacher(教师) read(阅读)reader(读者) 后缀or invent(发明)inventor(发明家)
2、 visit(访问)visitor(访问者) 后缀tion invent(发明)invention(发明) operate(手术)operation(手术)名词变形容词：后缀y wind(风)windy(刮风的) sun(太阳)sunny(晴朗的) 后缀ful help(帮助)helpful(有帮助的) care(小心)careful(小心的) 后缀ly friend(朋友)friendly(友好的)形容词变名词：+后缀ness good(好的)goodness(善良，美德) kind(和善的)kindness(和善)形容词变副词：后缀ly bad(坏的)badly(糟糕地) quick(快的
3、)quickly(迅速地)改变词义：前缀un happy(高兴的)unhappy(不高兴的) usual(平常的)unusual(不平常的)转化词：转化词是指由一种词类转用作另一种词类的词。例如：hand(n .)手， hand(v .)传递， dry(adj .)干燥的， dry(v .) 烘干说明初中总复习中，词汇的复习十分重要。掌握单词和词组的用法是学好语言的前提之一。没有一定的词汇量，不掌握词语的基本用法，就失去了英语知识复习的基础，也就更谈不上灵活运用和综合分析能力了。(2)词形变化英语词汇的词形变化除了前面讲的词根派生词缀构成的派生词的变化外，还存在有一些单词词尾的屈折变化，它们是
4、：1)表示名词复数的词形变化。例如：handhands(手) picturepictures(图片)knifeknives(小刀) citycities(城市)2)表示形容词、副词的比较级和最高级的词形变化。例如：cheapcheapercheapest(便宜的)latelaterlatest(迟来的，迟来地)earlyearlierearliest(早的、早地)3)表示动词一般现在时第三人称单数的词形变化。例如：cleancleans(打扫) catchcatches(按住) carrycarries(携带)4)表示动词过去时和-ed分词的词形变化。例如：catchcatched(捉住) c
5、arrycarried(搬运)closeclosea(关闭) stopstopped(阻止)5)表示动词-ing分词的词形变化。例如：walkwalking(走) makemaking(做) sitsitting(坐)二、难点是：如何运用词或词组。三、考点是：(1)单词拼写。(2)词形变化。(3)对词语的理解运用和相似词语的辨析。有关词汇的考题在中考中有10分左右。【经典范例引路】例1按要求写出下列单词的适当形式。1 .Well(最高级)_ 2.begin(现在分词)_3 .busy(反义词)_ 4.he(反身代词)_(2001年甘肃省中考题)简析：此题是对词形变化和单词的正确拼写的考查。要正
6、确解答，应熟练掌握规律性的变化形式，并牢固记忆一些特殊的词形变化。第1小题是考查副词的最高级。形容词和副词的比较级和最高级的构成分为规则变化和不规则变化。well的最高级属于不规则变化，为best。第小题是考查现在分词的构成。现在分词的构成为：(1)直接在动词原形后加-ing。(2)以不发音的e结尾的动词，先去e ,再加-ing。(3)以重读闭音节结尾且末尾只有一个辅音字母，先双写这一辅音字母，再加-ing。此题符合第三条。故答案为beginning。第3小题是考查词义及单词拼写。busy意为“繁忙的，忙的”它的反义词应为“空闲的，闲的”free。故答案为free。第小题是考查人称代词对应的反
7、身代词。答案为himself。例2选择与句中划线部分意思相同或相近的词或短语。( )1 .Mary called him three times yesterday , but nobody answered .A .visited B .gave a message to C .told D .phoned( )2 .Jim comes to visit us sometimes .

9、 speak to the headmaster ? Hold on , please .A .Speak louder B .Wait a momentC .Call again D .Speak out(2001年河北省中考题)简析：选出能替换划线部分的选项，这是一种常见题型。做此类题时应注意以下几点：(1)弄懂句意，特别是划线部分意思，以及各选项的意思。(2)能替换划线部分的选项与划线部分意思要相同。(3)选项与划线部分在句法功能上保持一致。第小题划线部分called后接him(sb)，首先要知道它在句中的意思，为“给打电话”。选项意为“访问”，选项意为“给捎口信”，选项意为“告诉”，只
10、有选项 .phoned意人“给打电话”，与划线部分意思相同。且phoned与called的句法功能也相同。故答案为。第小题划线部分sometimes意为“有时，某时”。A选项意为“准时，按时”，B选项意为“一直总是”，C选项意为“有时，某时”，D选项意为“许多次”。故答案为C。第3小题划线部分in the end意为“最后，终于”。A选项意为“起初，开始”，B选项意为“在开始时”，C选项意为“在末尾”，D选项为“最后，终于”。故答案为D。第4小题划线部分Thats all right在此处意为“不要紧，没关系”，用来回答别人道歉的用语。A、B、C、D四个选项中只有It doesnt matte
11、r与Thats all right意义相同。故答案为B。第5小题划线部分Hold on在此处意为“等一会儿”，是打电话时的交际用语。只有wait a moment与Hold on 意义相同，故答案为B。例3 单项选择。( )1 .Students are usually interested in sports . Some like running ;some like swimming ;_like ball games . (2001年上海市中考题)A .the others B .others C .the other D .other( )2 .Can you speak Chine
12、se ,Peter ? (2001年北京市海淀区中考题) Yes , but only_ .A .little B .few C .a little D .a few( )3 .Dont worry ,Ill take good care Polly .(2001年天津市中考题)A .for B .of C. with D .to简析：此题是考查词语意义和用法上的区别，以及词语的固定搭配。在做此类题时，我们应注意：(1)先读懂题意，找出考查点。(2)观察分析空格与它的前后部分的联系及空格在句中的句法功能。(3)根据题意及分析结果，对比所有选项，选择最恰当的选项。(4)对于难度较大、很难直接从正
13、面找到答案，就可采用排除法根据题意和所学知识排除错误答案。剩下的便是正确答案。第1小题是考查the others ,others ,the other ,other这四者在意义和用法上的区别：the others特指某一范围内的“其余的人(物)”而others泛指“其余的人(物)”它常和some对比使用，即“some . . .others . . .”，the other特指“(两个中的)另一个”，other泛指“另一个”。故答案为B。第2小题是考查little ,few ,a little ,a few的用法：某一语言不可数，因此B、D两选项不成立。而little是表示否定意义，a lit
14、tle表示肯定意义。根据题干的意思应为肯定，故答案为C。第3小题是考查take care of这一固定词组。故答案为B。【综合能力训练】 .从下列A、B、C、D四个选项中找出恰当的字母或字母组合使单词完整正确。( )1 .q ter A .ar B .or C .wor D .uar( )2 .know ge A .led B .lid C .lad D .le( )3 .Sat day A .er B .ir C .ur D .or( )4 .po ble A .si B .ssi C .se D .sse( )5 .lang ge A .wi B .wa C .ue D .ua( )6 .
