小学英语语法高级篇
第1课 名词
名词是指表示人和事物名称的词,可以分为专有名词和普通名词两大类。
这里强调两点:不可数名词都默认为单数,所以总是用is或者was。
可数名词复数形式的构成规则:
a.一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds
b.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches
c.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries
d.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives
e.不规则名词复数: man-men, woman-women, policeman-policemen, policewoman-policewomen, mouse-mice child-children foot-feet ,.tooth-teeth fish-fish, people-people, Chinese-Chinese, Japanese-Japanese
f.以o结尾,表示无生命的物体时加s, 表示有生命的物体时,加es,都读/ z /
e.g. photo-photos, piano-pianos, radio-radios, zoo-zoos
potato-potatoes,tomato-tomatoes,mango-mangoes,hero-heroes
▲ fish表示鱼的数量时,单复数同形;表示鱼的种类时,复数为fishes.
e.g. My cat had two fish for lunch.
You can see a lot of different fishes in the lake.
g、不可数名词一般只有原形,没有复数形式,但是可以借助量词表示一定的数量。如果表达两个或两个以上的概念时,量词需要用复数形式,不可数名词不变。
e.g. a bottle of water ,a cup of coffee,two glasses of milk ,five bags of rice
▲ 这种形式用于可数名词时,量词和可数名词都要用复数。
e.g. ten baskets of eggs
第2课 代词

①形容词性物主代词后面一般要带上名词。如:my watch, his cousin, our school
②名词性物主代词本身就可以看作是名词,故其后不能再加名词,可单独使用。
e.g. —Is that your bike? —No. Mine is blue.
第3课 形容词
形容词用来修饰名词或代词,表示人或事物的性质、状态和特征。它的位置通常放在被修饰的名词前,也可以放在be动词和look、feel、taste、sound、get之后。
在英语中,形容词有三个等级,即原级、比较级和最高级。
形容词比较级的构成规则:
① 一般在词尾加er
e.g. taller,longer,stronger,younger
② 以字母e结尾,只加r
e.g. late-later,nice-nicer
③ 以辅音字母+y结尾,变y为i,再加er
e.g. heavy-heavier
④ 双写末尾的辅音字母,再加er
e.g. fat-fatter,thin-thinner,big-bigger
⑤ 双音节和多音节词的比较级,在原级前加more
e.g. more beautiful,more careful
⑥ 不规则变化
e.g. good-better,many / much-more,far-farther,bad / ill-worse
3、三个或三个以上的人或物进行比较,用形容词最高级。
结构为:the + 形容词最高级 +in/of等表示范围的短语,表示“最……”。
e.g. Autumn is the best season in New York.
She is the tallest girl of our three.

第6课 动词
动词是表示动作或行为的词。按其词义和在句子中的作用可以分为连系动词、助动词、情态动词和行为动词。
1、be动词(am,is,are)
① be动词做谓语时,要与主语在人称和数上保持一致。
用法口诀: 我用am,你用are,is 用在他、她、它,复数全用are。
如:I am a teacher. You are a student. She is a nurse. We are Chinese.
② be动词的否定形式:am not(无缩写形式),is not=isn’t,are not=aren’t
2、助动词(do,does,did)
① do,does用于一般现在时,does用于第三人称单数,其他人称和数用do。其过去式did用于一般过去时。他们通常用在疑问句和否定句中。助动词后动词要用原形。
如:Do you like this film?
Does she like playing football?
I didn’t go to school yesterday.
② 否定形式:do not = don’t,does not =doesn’t,did not=didn’t
3、情态动词(can,may,must,should,will,would,shall等)
情态动词表示说话人对某一动作或状态的态度,表示“可能”,“可以”,“需要”,“必须”,“应当”等意思。情态动词没有人称和数的变化,后面的动词要用原形。
1)can和may都可以用来表示请求或允许,但may比can更正式,更客气些。
如: Can I use your pen? May I come in?
2)must和should
① must意为“必须,应当”,含有一种命令的语气,比较生硬,不容商量。
② should意为“应当,应该”,表示建议或劝告,语气比较委婉,客气。
如:You must finish your homework before you go to bed.
You should stay in bed and have a good rest.
3)will和would用于疑问句,表示说话人向对方提出请求或询问,用would比will更委婉,更客气。如:Will you please open the window? Would you like some coffee?
注意区别:
I’d like… 我想要……(接名词) 如:I’d like some tea.
I’d like to… 我想要做……(接动词原形)如:I’d like to go with you.
I like… 我喜欢……(接名词或动名词)如:I like monkeys. I like reading.
4) shall 在问句中表示征求对方的意见,主要用于第一人称。
如:Shall we go there by bus?
5)否定形式:can’t,may not,mustn’t,shouldn’t,wouldn’t,shall not
4、行为动词
行为动词也叫实意动词,是具有实际意义的动词。如run(跑), jump(跳),
listen(听),sing(唱),eat(吃),think(想)等。
行为动词在句子中有人称和时态的变化。
在英语中,不同时间里发生的动作或存在的状态,需要用不同的动词形式来表现,这就叫时态。

一般过去时 现在进行时 一般将来时
