(3)不可数名词作主语时,谓语动词用单数形式。如:
There is some ice cream in the fridge.
冰箱里有些冰淇淋。
(4)对不可数名词前的数量修饰语提问应该用how much,而不用how many。
可数名词复数形式的构成:
(1)规则变化
①一般在名词后直接加-s。如:
cake-cakes egg-eggs
②以s,x,ch,sh结尾的名词后加-es。如:
class-classes watch-watches
③以“辅音字母+y”结尾的名词,将y改为i,再加-es。如:
family-families party-parties
④以f或fe结尾的名词,将f或fe改为v,再加-es。如:
knife-knives shelf-shelves leaf-leaves wolf-wolves life-lives wife-wives
⑤以o结尾的名词,有生命的加-es,没有生命的加-s; 以oo结尾的名词都加-s。如:

(2)不规则变化
①通过名词内部的变化构成复数。如:
man-men woman-women foot-feet tooth-teeth
②单、复数同形。如:sheep,deer.Chinese等。
③复合名词变为复数时,第一个成分是含有表示性别的man或woman时,两个成分都要变成复数。如:
