三、可数名词与不可数名词
根据能否与不定冠词aan连用或能否被计数可以将名次分为可数名词与不可数名词。
前面可以加不定冠词aan,可以被计数的名词为可数名词,英文为countable noun,简写为[c]。可数名词具有单数和复数两种形式。如:
a lion two lions
a tiger three tigers
a snake ten snakes
a bag ten bags
a family many families
相反,前面不可以加不定冠词aan,无法被计数的名词为不可数名词,英文为uncountable noun,简写为[u]。比如water, 不能说a water或ten water。要表示其数量,必须在前面加上表示数量的单位。如:
water a glass of water two glasses of water
rice a bag of rice three bags of rice
tea a cup of tea four cups of tea
ink a bottle of ink five bottles of ink
advice a piece of advice some picecs of advice
口诀:不可数名词的范围
金木水火土,肉面食茶布;液体粉末状,皆为不可数。
四、可数名词的复数变化
1.规则变化:
规则一、大部分名词在词尾加-s;如:
mapmaps treetrees birdbirds pilotpilots orangeoranges bikebikes
