词汇重点、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erdrive(驾驶)driver(驾驶员)teach(教)teacher(教师) read(阅读)reader(读者) 后缀orinvent(发明)inventor(发明家) visit(访问)visitor(访问者) 后缀tioninvent(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fulhelp(帮助)helpful(有帮助的) care(小心)careful(小心的) 后缀lyfriend(朋友)friendly(友好的)形容词变名词：+后缀nessgood(好的)goodness(善良，美德) kind(和善的)kindness(和善)形容词变副词：后缀lybad(坏的)badly(糟糕地) quick(快的)quickly(迅速地)改变词义：前缀unhappy(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：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)carrycarried(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。一根据句意和所给中文，写出正确形式的英文单词1.I live with my family in a _ house. （木头的）2.Is Kates room very _? （整洁） 3.You should keep _ in the library. （安静）4.There are two _ books in our library.
