在可数名词与不可数名词上一般出现这样几类,(1)分辨是哪一类名词,并根据结论做选择.(2)可数名词复数的不规则变化.(3)不可数名词的量化表达.所以,考生首先要能够明确哪些是可数名词,哪些是不可数名词.其次,还要知道可数名词的复数的变化规则.可数名词的变化规则一般是在单词后面加-s 或-es,如:
1.desk---desks bed---beds piano---pianos
hat---hats bag---bags photo---photos
2.bus---buses box---boxes
watch---watches brush---brushes
3.t omato---tomatoes potato---potatoes
hero---heroes Negro---Negroes
4.leaf---leaves knife---knives
5.baby---babies family---families
另外,还要记住一些特殊的名词的变化形式,如:
Chinese---Chinese Japanese---Japanese
Englishman---Englishmen Frenchman---Frenchmen
Russian---Russians American---Americans
German --- Germans
child---children foot---feet
man---men woman---women
tooth---teeth goose --- geese
deer---deer sheep---sheep
还要掌握不可数名词的量化表达有:a piece of、a bag of、a bottle of、a cup of、a glass of .
另外,大家应注意:单数集合名词作主语时谓语动词“数的”变化:单数集合名词如class,police,family,school,group,team等.尽管形式上是单数,意义上都是复数,因此,一般要与复数谓语动词连用,例如:
Class Five have a foreign friend.
五班有一位外国朋友.(这里的五班指五班的同学的.)
His family are good to me.他的家人对我很好.(很显然,这里的family指家庭成员.)
当上述集合名词着重指“整体”时,意义上则是单数,因此,要与单数谓语动词连用.例如:
Our school team often plays well in our city.
我们的校队经常在我们市踢得很好.(这里的team 指整个队,但意义上仍为单数,故谓语动词用plays.
