英语单词词性（词类）
一．名词：代替人或事物名称的词。分可数和不可数。可数名词有单复数形式，不可数名词视为单数形式，作主语时候，谓语用单数。但如果有量词表示不可数名词数量时，则作主语时要与量词的数保持一致。
名词变复数规则：①.一般加s;②.以s ,x ,sh,ch o(黑人英雄爱吃西红柿土豆和芒果negro,hero,tomato,potato,mango)后加es;③.以辅音字母加y 结尾的变y为i再加es;④.以f/fe 结尾的，变f/fe为v，再加es；⑤.特殊形式特殊记忆。
（1）.先将下面可数名词找出来，然后再将其变为复数形式。
fish bread box fox bus grass peach watch potato water tomato hero baby key broccoli boy knife leaf child sheep mouse Chinese Japanese fly man woman
（2）.用括号中词的适当形式填空：
1.I ate many ______(tomato)this morning.
2.The _____(woman) in red are my aunts.
3.My uncle has three _____(child).
4.The milk in the glass _____(be) white but the two glasses of juice ____(be) orange.
5.Koalas like eating_______(leaf) and _____(grass).
名词所有格：表示一种所属关系，“……的”。
一般在有生命的名词后加“’s”；以s 结尾的复数名词只打“’”不加s;表示两者共有的只在后者后加“’s”;表示两者分别所有的则要在两者后分别加
“’s”;在一些表示居所的名词可以直接在名词后加“’s”,省去后面的居所名词；国家、时间等无生命的名词可加“’s”表示所有格；无生命的名词的所有格用of 介词短语表示。
1._____(Tom的)bag is here and ______( Jack的)is there.
2.This is ___________(Tom 和Jack的)room.
3.These are ____________(Tom的和Jack的)rooms.
4.The ________(students的)bags are heavy .

7._______(today)newspaper is here.
8.The______(children)faces are red.

二．冠词：就是放在名词前帮助说明名词所指的人或事物。分定冠词the和不定冠词a/an.定冠词the表示特指，即可修饰可数名词也可以修饰不可数名词；不定冠词a/an表示泛指。其中a用于辅音因素前，an用于元音因素前。在下面空格上填冠词。
1.I have ___ book and ____book is ____ story book.
2._____woman with____ umbrella in her hand is my mother.
3.There is ____girl in the room and ____girl is Tom’s sister.
4.Tom is _____ first one to get to school every morning.

三．代词：用来代替名词、形容词或数词的。有人称代词（分主格和宾格）、物主代词（分形容词性物主代词和名词性物主代词）、指示代词（如this,that ,these,those）和不定代词(如some,many,much,any,等)。
人称代词巧记规则：
人称代词很容易，我是我来你是你。主格作主语，主谓不分家；宾格作宾语，动介后面加上去。我主I 宾是me；男他he,女她she,还有him 和her 是宾格；it和you主宾同；我们主宾we,us;他们主宾the y,them。
1.____(我)am in the classroom.Tom is next to ____(我).
2.Let______(我们) go to the park today.______(我们)are happy.
3.Nice to meet _____(你).Where are _____(你)from?
4._____(他)is from Canada. Now listen to ____(他)，please.
5.______(她)is a beautiful girl.Everyone loves _____(她).
6.____(它)is a lovely cat.We all love _____(它).
7.______(她们)are beautiful hostesses.All the people look at _______(她们).
物主代词巧记规则：
物主代词更轻松，我的你的要分清。形容词性作定语，后面定把名词用；名词性，独立用，主宾表语它都充。名词性变轻松，一变二同四S。
一变my-mine,二同his-his,its-its,
四S:our-ours,your-yours,her-hers,their-theirs
1.This is _____(我的)book,it’s not ______(你的).
2.That is not ______(你的)pen,it’s______(我的).
