中考英語(yǔ):可數(shù)不可數(shù)千萬(wàn)別馬虎
英語(yǔ)中的名詞按其表示的事物性質(zhì)的不同可分為可數(shù)名詞與不可數(shù)名詞。這兩種名詞在用法上是有區(qū)別的,現(xiàn)歸納
一、可數(shù)名詞有單數(shù)、復(fù)數(shù)之分,如:
map→maps;onion→onions;baker→bakers
不可數(shù)名詞沒(méi)有復(fù)數(shù)形式,只有單數(shù)形式。如:
some water;a lot of bread
二、單數(shù)可數(shù)名詞表示泛指時(shí),前面要用不定冠詞a(an);而不可數(shù)名詞不能用a(an)。如:
Li Hong is a driver.I am a teacher.李紅是一名司機(jī),我是一名教師。
We can’t see milk on the table.我們看不見(jiàn)桌上有牛奶。
[友情提醒]在表示特指時(shí),不可數(shù)名詞和可數(shù)名詞前都要用定冠詞the,如:
Pass me the ball,please.請(qǐng)把球傳給我。
The chicken on the plate is yours.盤子里的雞肉是你的。
三、可數(shù)名詞表示復(fù)數(shù)意義時(shí)可用many等詞修飾。如:
many apples;a lot of tomatoes;a few pens
不可數(shù)名詞則要用much、a little等詞修飾。如:
much meat a little breadlittle water
[友情提醒]這兩類名詞都可以被some、any、a lot of(lost of)等修飾。如:some eggs/paper(紙)。
A lot of (lots of) knives/orange juice
四、可數(shù)名詞前通?捎镁唧w的數(shù)詞來(lái)修飾。如:
three women
ten babies
five pieces of bread 五片面包
五、可數(shù)名詞作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞的單、復(fù)數(shù)與主語(yǔ)的單、復(fù)數(shù)須保持一致。不可數(shù)名詞作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞只能用單數(shù)形式。如:
There is some rice in the bowl.碗里有些米飯。
All the students are in the classroom.所有的學(xué)生都在教室里。
[友情提醒]如果不可數(shù)名詞前有復(fù)數(shù)名詞短語(yǔ)修飾時(shí),謂語(yǔ)動(dòng)詞須用復(fù)數(shù)形式。如:
There are two bags of rice in the room.房間里有兩袋大米。
六、對(duì)可數(shù)名詞的數(shù)量提問(wèn)用how many;對(duì)不可數(shù)名詞的數(shù)量提問(wèn)要用how much,但對(duì)不可數(shù)名詞前表示數(shù)量名詞中的修飾語(yǔ)提問(wèn)時(shí)要用how many。
如:
I can see two pictures on the wall. → How many pictures can you see on the wall?
There is a lot of pork in the basket. → How much pork is there in the basket?
I want three glasses of water. → How many glasses of water do you want?
七、另外,有些集合名詞也是可數(shù)名詞,但不同的是,它們以單數(shù)形式出現(xiàn),表示復(fù)數(shù)概念,如people,police,family等;而有些可數(shù)名詞本身就以復(fù)數(shù)形式出現(xiàn),如clothes,glasses(眼鏡)等;有的可數(shù)名詞單、復(fù)數(shù)形式相同,如Japanese,sheep,Chinese等。如:
The Chinese people are hardworking and brave.中國(guó)人民勤勞勇敢。
The sports clothes are new.這些運(yùn)動(dòng)服是新的。
I have one sheep. He has two sheep.我有一只羊,他有三只羊。
