1、1单元语法聚焦三单元语法聚焦三 名词复数 treetrees(树)(2)以s, x, sh, ch 等结尾的名词,通常在词尾加es。例如:busbuses(公共汽车); boxboxes(盒子);dishdishes(盘子)(3)以y 结尾的名词,其复数构成要分两种情况:以“辅音字母y”结尾的名词,将y 变为 i,再加es;以“元音字母y”结尾的名词,直接在词尾加s。例如:citycities(城市); boyboys(男孩);keykeys(钥匙)(4)以o 结尾的名词,有些在词尾加s,有些在词尾加es。例如:2pianopianos(钢琴); tomatotomatoes(西红柿)注意:初

2、中英语中,以o 结尾的名词词尾后加s 构成复数名词的有 zoo(动物园),photo(照片),piano (钢琴);词尾加es 的有 tomato(西红柿),potato(土豆),hero(英雄)。(5)以f 或fe 结尾的名词,一般将f 或fe 改为ves。例如:knifeknives(小刀); thiefthieves(贼);lifelives(生命); wifewives(妻子)注意:初中英语中,这类名词主要有 wife(妻子),life(生命),knife(小刀),leaf(树叶),thief(贼),half(一半),self(自己),wolf(狼);它们的复数形式均是将词尾的f 或f

3、e 变为ves。另外,也有以f 结尾的名词直接加s 构成复数(如:roof roofs 屋顶),但这在初中英语中很少见。2单数与复数同形的名词初中英语中,单数和复数同形的名词主要有 sheep(绵羊),fish(鱼),deer(鹿),Chinese(中国人),Japanese(日本人),Swiss(瑞士人)等。注意:fish 有时也用 fishes,这样的复数形式尤其表示种类。3不规则名词的复数有些名词单数变复数时,没有一定的规则。例如:manmen(男人);womanwomen(女人);childchildren(孩子);toothteeth(牙齿);footfeet(脚); mousemi

4、ce(老鼠)注意:一些以man, woman 结尾的合成词,构成复数时与 man, woman 的变化形式相同。例如:policemanpolicemen(警察);policewomanpolicewomen(女)警察但是 human(人),German(德国人)不是合成词,其复数不能仿照 man 的变化规律,而是按规则变化,即 humans, Germans。另外,当 man 和 woman 用于名词前作定语时,若其后被修饰的名词为复数,则 man 和woman 也要用复数。例如:3man nursemen nurses(男护士)woman doctorwomen doctors(女医生)4

5、有些名词只有复数形式初中阶段常见的此类名词有 clothes(衣服); glasses(眼镜); scissors(剪刀); pants(裤子); trousers(裤子)等。二、实义动词 havehave 的用法1. He hashas three black hairs. 他有 3 根黑色的头发。2. I havehave short black hair. 我留着黑色短发。3. He hashas green eyes. 他长着绿色的眼睛。通过观察教材上的这三个句子,我们可以看出,表示“某人拥有某物”时,我们通常会用到动词 have。 关于它的用法,你了解多少呢?实义动词 havehav

6、e句式用法肯定句I/You/We/They haveHe/She/It has一般疑问句Do I/you/we/they have?Does he/she/it have?否定句I/You/We/They dont haveHe/She/It doesnt have通过表格可以看出:have 用作实义动词时,一般表示“有” ,它的第三人称单数形式是 has。1. 一般来说,主语是第三人称单数形式时,谓语动词用 has;主语是其他人称时,谓4语动词用 have。例如:He has two names. 他有两个名字。I have an elder brother. 我有一个哥哥。2. 变一般疑问

7、句时,通常借助助动词 do 或 does。主语是第三人称单数时,借助于助动词 does,句中 has 还原为 have;主语是其他人称时,借助于助动词 do,即“Do/Does主语have?” 例如:Does she have any pencils? 她有铅笔吗?Do you have brothers?你有兄弟吗?3. 变否定句时,一般在 have 前加 dont,在 has 前加 doesnt,此时 has 还原为have,即“主语dont/doesnthave” 。例如:They dont have children.他们没有孩子。She doesnt have any pencils

8、. 她没有铅笔。记忆口诀实义动词 have 的用法动词 have 表示“有” ,位置就在主语后。“三单”主语用 has,其他人称用 have。一般疑问两法变:一是把它提句前,二是把 do/does 来添。否定句子也一样,就看 not 怎么放。.把下列名词变成复数形式1book _ 2.dress _3story _ 4.potato _5radio _ 6.leaf _7glass _ 8.dish _.用 havehave 或 hashas 填空1I _ many good friends.52Tom _ big blue eyes.3My classroom _ eight windows
