  初一英语上册知识点(一)

  二、be动词的用法

  be动词有三种变形,分别是:am, is, are。记忆口诀:

  "我"用am, "你"用are, is用于"他、她、它";单数全都用is,复数全部都用are。

  三、人称及人称代词的不同形式(主格和宾格)

  1、三种人称:第一人称(I, we),第二人称(you, you),第三人称(he, she, it, Maria)。

  2、人称代词的主格,即人称代词位于句子主语位置时的形态:I, We, You, You, He, She, It, Maria。

  3、人称代词的宾格,即人称代词位于句子宾语位置时的形态:me, us, you, you, him, her, it。

  4、形容词性物主代词:my, our, your, your, his, her, its, their。

  5、名词性物主代词:mine, ours, yours, yours, his, hers, its, theirs。

  6、反身代词:myself, ourselves, yourself, yourselves, himself, herself, itself, themselves。

  四、基数词(表示数量多少的词,大致相当于代数里的自然数)

  zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three,twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, forty, fifty, sixty,seventy, eighty, ninety, one hundred,one hundred and one。

  五、一般疑问句及特殊疑问句

  六、可数名词变复数

  可数名词变复数时,有规则变化和不规则变化两种。

  1、规则变化:

  (1)一般情况直接在词尾加"-s ",如:cake-cakes, bag-bags, day-days, face-faces, orange-oranges等;

  (2)以s, x, sh, ch结尾的词,要在词尾加"-es ",如:bus-buses, watch-watches, box-boxes等;

  (3)以辅音字母加y结尾的词,变y为i再加"-es ",如:baby-babies, country-countries, family-families等;

  (4)部分以f (e)结尾的词,变f (e)为"ves ",如:knife-knives, half-halves等;

  (5)以o结尾的词,加"-s "或"-es ",如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等。记忆口诀:除了"英雄"hero外,凡是能吃的,加"-es ",不能吃的加"-s "。

  2、不规则变化:

  (1)改变单数名词中的元音字母:man-men, woman-women, foot-feet, tooth-teeth等;

  (2)单、复同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;

  (3)其他形式:mouse-mice, child-children等。

  七、简单句的成分及主谓一致原则

  最基本构成:主语+谓语+宾语,其中谓语由动词来充当。

  主谓一致原则,就是句子的谓语要始终与主语保持数量上的一致性。当主语是第三人称单数(简称"三单")时,谓语动词也要相应变成单数形式;当主语非"三单"时,谓语动词就用原形。实意动词变"三单"的规则如下:

  (1)一般动词在词尾加"-s ",如:like-likes, tell-tells, play-plays等;

  (2)以字母s, x,ch, sh结尾的动词加"-es ",如:guess-guesses, teach-teaches, watch-watches等;

  (3)以o结尾的动词一般加"-es ",如:do-does, go-goes等;

  (4)以辅音字母加y结尾的动词,先变y为i,再加"-而是",如:fly-flies, carry-carries等;

  (5)have的三单形式是has。

  八、冠词的用法(名词前面必须要有冠词)

  冠词分为定冠词(the)和不定冠词(a, an)两种。

  1、定冠词the表示"特指",可译为"这个"、"那个"、"这些"、"那些"。

  2、不定冠词a, an用来表明(可数)名词的数量是"一个"。an用于以元音开头(注意不是以元音字母开头)的单词前,a则英语非元音开头的单词前。

  3、不定冠词a, an与基数词one的区别是:不定冠词不是刻意强调"数量",而基数词则强调"数量"。

  九、助动词(do, does )的用法

  只有实意动词作谓语时才涉及使用助动词。以like为例:

  (1)当句子为肯定句时不涉及使用助动词,只涉及"主谓一致"原则。

  eg : I like English a lot.

  Michael likes Chinese food very much.

  (2)当句子为否定句时,要根据主语的人称来决定使用相应的助动词:当主语为"三单"时,要使用does;当主语为"非三单"时,用助动词原形do。例如把下列句子变否定句:

  Kangkang likes math.----Kangkang doesn't like math.

  They like sports.------They don't like sports.

  (3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句:

  Michael likes Chinese Food.----Does Michael like Chinese food? Yes, he does./ No, he doesn't.

  Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.

  十、名词所有格

  1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's bikes;

  2、用of表示"......的",但要从of后往of前翻译:a book of mine(我的一本书)

  3、have与of的区别:

  have一般表示"主动拥有",往往用于有生命的人或动物;无生命的物体一般不能"主动拥有",表示所属关系时要用of。例如:

  I have a new bike. She has two big eyes.

  a door of the house

  十一、初一英语上册知识点之课本中的知识点

  (9)both与all的区别:

  both表示"两者都......";all表示"三者及以上都......"。

  2、Unit 3--Unit 4

  (1)speak的用法

  speak与say不同:speak表示"说"的动作,不表示"说"的内容;say则表示"说"的内容。

  help sb. with sth.(帮助某人做/补习......)

  not...at all(一点都不);Not at all.(没关系/别介意)

  Do you have any money?

  (3)have a seat = take a seat(请随便坐)

  (4)祈使句(表示命令或请求的句子)

  祈使句一般都省略了主语You,所以其否定句直接用Don't开头。例如:

  Don't go there!

  (5)问职业:

  What does sb. do?

  What is sb.?

  What's sb.'s job?

  (6)work与job的区别:

  on the desk/ wall/ farm/ playground

  (8)in hospital(住院);in the hospital(在医院里)

  look after(照料/照顾/照看)

  (10)"吃"一日三餐要用have:have breakfast/ lunch/ supper

  have...for breakfast/ lunch/ supper

  be kind to sb.

  (11)try on这个词组可合可分:名词可以放在这个词组的中间或后面,但代词只能放在词组的中间。

  (12)在口语中往往用take表示"买"。

  (13)how many与how much的区别:

  how many + 可数名词;how much + 不可数名词

  (14)What do you think of...? 是询问对方对某事物的看法;

  How do you like...? 是问对方对某事物喜欢的程度。

  think about(考虑)

  Thank you all the same. (即使对方没能帮上忙,也要礼貌道谢)

  Thanks. = Thank you.(thank作为动词,不能单独使用。)

  (15)one与it的区别:

  当上下文说的是同一种类事物时,任意一个可以用one来代替;如果上下文所说的是同一个事物时则用it。例如:

  Ann :I have a yellow bag.

  Jane :I have a green one.

  Tom : Hey, Mike. Where is your bike?

  Mike : Look, it's over there.

  (16)倒装句

  Here you are.

  (18)go + v.-ing结构的含义:为了实现某目的才去的。例如:

  go fishing/ boating/ swimming/ shopping等

  (19)have to do sth.(非主观因素,强调客观因素,"不得不去做某事")

  must 则表示主观愿望

  (20)fly a kite = fly kites

  be free = have time

  (21)句型"该干某事了。":It's time to do sth. = It's time for sth.

  例如:该吃午饭了.

  It's time to have lunch. = It's time for lunch.

  (22)时间的表述

  当分针所指的时间大于0分、小于等于30分钟时,用"分钟"past"小时"。例如:

  8:23--twenty-three past eight

  当分针所指的时间大于30分钟、小于60分钟时,用"剩余的时间"to"下一个整点"。例如:

  8:49--eleven to nine

  当然,还可以直接按照小时、分钟去读出时间,例如:

  8:23--eight twenty-three; 8:49--eight forty-nine

  整点则在数词后加"-o'clock",例如:8:00--eight o'clock

  在钟点前介词要用at.
