初中英語(yǔ)語(yǔ)法詞類(lèi).doc

語(yǔ)法（詞法）英語(yǔ)中常見(jiàn)的幾類(lèi)詞有：名詞，代詞，冠詞，數(shù)詞，形容詞、副詞，介詞【名詞】名詞是表示人、地方、事物或抽象概念名稱(chēng)的詞，可以說(shuō)名詞是萬(wàn)物之名稱(chēng)。它們可以是： 人的名字 ，地方名稱(chēng) ，職業(yè)稱(chēng)呼 ，物品名稱(chēng) ，行為名稱(chēng) ，抽象概念 1名詞的可數(shù)與不可數(shù)可數(shù)名詞指表示的人或事物可以用數(shù)來(lái)計(jì)量，它有單數(shù)與復(fù)數(shù)兩種形式。不可數(shù)名詞指所表示的事物不能用數(shù)來(lái)計(jì)量。物質(zhì)名詞與抽象名詞一般無(wú)法用數(shù)目，來(lái)統(tǒng)計(jì)，都成為不可數(shù)名詞。不可數(shù)名詞前一般不能用冠詞a、an來(lái)表示數(shù)量，沒(méi)有復(fù)數(shù)形式。要表示“一個(gè)”這一概念，就須加a piece of這一類(lèi)短語(yǔ)。要注意許多名詞在漢語(yǔ)里看來(lái)是可數(shù)名詞，在英語(yǔ)里卻不可數(shù)。如：chalk，paper，bread，rice，grass，news等。2名詞的復(fù)數(shù)（1）規(guī)則變化A一般情況下加-s。B以s, x, ch, sh, 結(jié)尾的加-es。如：bus-buses，box-boxes，watch-watches，brush-brushesC以輔音字母加y結(jié)尾的改y為i再加-es。如：city-cities，country-countriesD以f，fe結(jié)尾的，去掉f或fe，變成v再加-es。（2）不規(guī)則變化A元音發(fā)生變化。如：man-men，woman-women，foot-feet，tooth-teeth，mouse-miceB詞尾發(fā)生變化。如：child-childrenC單、復(fù)數(shù)同形。如：fish-fish，Japanese-Japanese，Chinese-Chinese，sheep-sheep3物質(zhì)名詞（不可數(shù)名詞）量的表示方法（1）用much，a little，a lot of等表示（2）用容器表示a bowl of rice，a glass of water，a cup of tea，a piece of paper， two glasses of milk，two pieces of paper4名詞的所有格(1) 名詞所有格的構(gòu)成法 A單數(shù)名詞詞尾加 s，復(fù)數(shù)名詞詞尾若沒(méi)有s，也要加 s。the workers bike，the Children s ball B表示幾個(gè)人共有一樣?xùn)|西，只需在最后一個(gè)人的名字后加 s若表示各自所有，則需在各個(gè)名字后 s。如： This is Lucy and Licy s room These are Kates and jack s roomsC. 如果是通過(guò)在詞尾加s構(gòu)成的復(fù)數(shù)形式的名詞，只加。如:the students books，the girls blouses(2)名詞+of+名詞: 名詞是有生命的，我們就用s結(jié)構(gòu)來(lái)表示所有關(guān)系。如果名詞所表示的事物是無(wú)生命的，我們就要用名詞+of+名詞的結(jié)構(gòu)來(lái)表示所有關(guān)系.如:the legs of the desk，the door of the room但在表示名詞所有格時(shí)， s結(jié)構(gòu)也?？赊D(zhuǎn)換成of結(jié)構(gòu)。有些表示時(shí)間,距離、國(guó)家、城市等無(wú)生命的東西的名詞，也可以加s來(lái)構(gòu)成所有格.如:ten minutes walk，todays newspaper(3)雙重所有格所謂“雙重所有格（doublegenitive）”，是指名詞所有格或名詞性物主代詞同of構(gòu)成的所有格，即“of名詞所有格”。雙重所有格有以下幾個(gè)特征：1）“of名詞所有格”中的名詞必須表示人，不能表示事物。因此，我們可以說(shuō)：aplayof Shakespeares（莎士比亞的一個(gè)戲?。琣friendofmywifes（我妻子的一個(gè)朋友），但卻不能說(shuō)afunneloftheships或alegofatables，而且該名詞必須是特指的，不能是泛指的。比如我們可以說(shuō)，afriendofthedoctors（這位醫(yī)生的一個(gè)朋友），anovelofthewriters（那位作者的一部小說(shuō)），而不能說(shuō)afriendofadoctors或anovelofawriters。選擇正確答案1.
