七年級英語上冊知識點梳理人教版
2)以字母s, x,ch, sh結(jié)尾的動詞加“-es ”,如:guess-guesses, teach-teaches, watch-watches等;
3)以o結(jié)尾的動詞一般加“-es ”,如:do-does, go-goes等;
4)以輔音字母加y結(jié)尾的動詞,先變y為i,再加“-而是”,如:fly-flies, carry-carries等;
5)have的三單形式是has。
八、冠詞的用法(名詞前面必須要有冠詞)
冠詞分為定冠詞(the)和不定冠詞(a, an)兩種。
1、定冠詞the表示“特指”,可譯為“這個”、“那個”、“這些”、“那些”。
2、不定冠詞a, an用來表明(可數(shù))名詞的數(shù)量是“一個”。an用于以元音開頭(注意不是以元音字母開頭)的單詞前,a則英語非元音開頭的單詞前。
3、不定冠詞a, an與基數(shù)詞one的區(qū)別是:不定冠詞不是刻意強調(diào)“數(shù)量”,而基數(shù)詞則強調(diào)“數(shù)量”。
九、助動詞(do, does )的用法
只有實意動詞作謂語時才涉及使用助動詞。以like為例:
1)當句子為肯定句時不涉及使用助動詞,只涉及“主謂一致”原則。
eg : i like english a lot.
michael likes chinese food very much.
2)當句子為否定句時,要根據(jù)主語的人稱來決定使用相應的助動詞:當主語為“三單”時,要使用does;當主語為“非三單”時,用助動詞原形do。例如把下列句子變否定句:
kangkang likes math.----kangkang doesn't like math.
they like sports.------they don't like sports.
3)當句子變疑問句時,同樣要根據(jù)句子的主語來決定在句首使用do或does.例如下列句子變問句:
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、名詞所有格
1、kangkang's books;tom and helen's desk; ann's and maria's bikes;
2、用of表示“......的”,但要從of后往of前翻譯:a book of mine(我的一本書)
3、have與of的區(qū)別:
have一般表示“主動擁有”,往往用于有生命的人或動物;無生命的物體一般不能“主動擁有”,表示所屬關(guān)系時要用of。例如:
i have a new bike. she has two big eyes.
a door of the house
十一、課本中的知識點
1、unit 1 ——unit 2
1)問候語:

how are you?---just ok, thank you. how are you?---not bad, thanks.

2)道別用語:
nice/ glad to meet/ see you.(meet用于初次見面,see用于熟人間)
nice to meet/ see you, too.
goodbye. byebye. bye. see you (later/ tomorrow/ next time)! so long! good night!
3)介紹人或者物的句型:this is...
4)excuse me.與i'm sorry.的區(qū)別:
excuse me.是要引起對方的注意,而i'm sorry.則是向?qū)Ψ降狼浮?br>5)詞組be from = come from
in english
5)當問句中問到this/ that時,回答要用it;問到these/ those時,要用they來回答。 例如: what's this in english?----it's an eraser.
what are those?----they are books.
6)對thanks.的回答:that's ok./ you're welcome./ my pleasur.
7)look the same = have the same looks
