2bus---buses box---boxes
watch---watches brush---brushes
3tomato---tomatoes potato---potatoes
hero---heroes Negro---Negroes
4 leaf---leaves knife---knives

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.
二、 名词所有格
名词所有格有两种形式：一是加’s，一种是用of来表示。一般情况下，指某人的某物用’s表示，而指某物的什么用of 短语来表示。另外，要注意凡是以s结尾的名词或规则名词的复数，不能直接加’s，而应该加-’即可。例如，boys’ clothes girls’ dresses。 不过，注意例外情况，例如， the boss’s handwriting，其中the boss’s 的-’s不可省略。因为在英语中，如果以-s 或-ss 结尾的名词不是复数复数形式，那么其名词所有格仍加-‘s。那么你会说“琼斯的小汽车”吗？对，Jones’s car。
