1desk---desks bed---beds piano---pianos
hat---hats bag---bags photo---photos
2bus---buses box---boxes
watch---watches brush---brushes
3tomato---tomatoes potato---potatoes
hero---heroes negro---negroes
4 leaf---leaves knife---knives
5baby---babies family---families
另外，還要記住一些特殊的名詞的變化形式，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
還要掌握不可數名詞的量化表達有： a piece of、a bag of、a bottle of、a cup of、a glass of
另外，大家應注意：單數集合名詞作主語時謂語動詞“數的”變化：單數集合名詞如class, police, family, school, group, team等。儘管形式上是單數，意義上都是複數，因此，一般要與複數謂語動詞連用，例如：
class five have a foreign friend.
五班有一位外國朋友。(這裡的五班指五班的同學的。)
his family are good to me. 他的家人對我很好。(很顯然，這裡的family指家庭成員。)當上述集合名詞著重指“整體”時， 意義上則是單數，因此，要與單數謂語動詞連用。例如，
our school team often plays well in our city.
我們的校隊經常在我們市踢得很好。(這裡的team 指整個隊，但意義上仍為單數，故謂語動詞用plays.
二、 名詞所有格
名詞所有格有兩種形式：一是加’s，一種是用of來表示。一般情況下，指某人的某物用’s表示，而指某物的什麼用of 短語來表示。另外，要注意凡是以s結尾的名詞或規則名詞的複數，不能直接加’s，而應該加-’即可。例如，boys’ clothes girls’ dresses。 不過，注意例外情況，例如， the boss’s handwriting，其中the boss’s 的-’s不可省略。因為在英語中，如果以-s 或-ss 結尾的名詞不是複數複數形式，那么其名詞所有格仍加-‘s。那么你會說“瓊斯的小汽車”嗎?對，jones’s car。
