no.2形容詞比較級
當(dāng)我們需要對事物作出比較時,需要用到比較級.比較級的句子結(jié)構(gòu)通常是:
什么+動詞be(am,is,are)+形容詞比較級+than(比)+什么,如:
I'm taller and heavier than you.(我比你高和重.)An elephant is bigger than a tiger.(一只大象比一只老虎大.)
形容詞的比較級是在形容詞的基礎(chǔ)上變化而來的,它的變化規(guī)則是:①一般的直接在詞尾加er,如tall-taller,strong-stronger,②以e結(jié)尾的,直接加r,如fine–finer,③以輔音字母加y結(jié)尾的,先改y為i再加er,如funny-funnier④雙寫較后的字母再加er,如big–bigger,thin–thinner,hot–hotter
☆注意☆
比較的兩者應(yīng)該是互相對應(yīng)的可比較的東西.典型錯誤:My hair is longer than you.(我的頭發(fā)比你長.)比較的兩者是我的頭發(fā),你(整個人),那么比較的對象就沒有可比性.應(yīng)該改為:My hair is longer than yours.或My hair is longer than your hair.
no.3動詞過去式
動詞的過去式的構(gòu)成規(guī)則有:
A,規(guī)則動詞①一般直接在動詞的后面加ed:如worked,learned,cleaned,visited②以e結(jié)尾的動詞直接加d:如lived,danced,used③以輔音字母加y結(jié)尾的動詞要改y為i再加ed(此類動詞較少)如study–studied carry–carried worry–worried(注意play,stay不是輔音字母加y,所以不屬于此類)④雙寫較后一個字母(此類動詞較少)如stopped
B,不規(guī)則動詞(此類詞并無規(guī)則,須熟記)
階段要記住以下動詞的原形和過去式:sing–sang,eat–ate,see–saw,have–had,do–did,go-went,take-took,buy-bought,get-got,read-read,fly-flew,am/is-was,are-were,say-said,leave-left,swim-swam,tell-told,draw-drew,come-came,lose-lost,find-found,drink-drank,hurt-hurt,feel-felt
no.4動詞現(xiàn)在分詞詳解
動詞的ing形式的構(gòu)成規(guī)則:
?、僖话愕闹苯釉诤竺婕由蟟ng,如doing,going,working,singing,eating②以e結(jié)尾的動詞,要先去e再加ing,如having,writing③雙寫較后一個字母的(此類動詞極少)有:running,swimming,sitting,getting
no.5英語人稱代詞主格及賓格
英語人稱代詞主格及賓格
人稱代詞分為主格和賓格,主格和賓格區(qū)別:主格和賓格漢語意思相同,但位置不同。
Eg:I(主格)"我"--me(賓格)"我"
主格在陳述句中通常放句首,賓格通常放在動詞后或介詞后,也就是說賓格,不放在句首。
Eg:I have a new car.(I主格)
Excuse me(me賓格)
I ask him to go(him賓格)
They sit in front of me(me賓格)
主格(8個):I我you你he他she她it它we我們you你們they他(她、它)們
賓格(8個):me我you你him他her她it它us我們you你們them他(她、它)們
no.6句型專項歸類
1.肯定句:是指用肯定的語氣來陳述的句子,
如:I'm a student.
She is a doctor.
He works in a hospital.There are four fans in our classroom.
2,否定句:含有否定詞或表示否定意義詞的句子,
如:I'm not a student.He does not(doesn't)work in a hospital.
There are not(aren't)four fans in our classroom.
☆注意☆小結(jié):
否定句主要是在肯定句的基礎(chǔ)上加上了否定詞"not".有動詞be的句子則"not"加在be后面,可縮寫成"isn't,aren't",但am not一般都分開寫.沒有動詞be的句子則要先在主要動詞的前面加上一個助動詞(do,does,did),然后在它后面加上"not",你也可以把它們縮寫在一起如"don't,doesn't,didn't).這三個助動詞要根據(jù)人稱和時態(tài)來選擇,其中"does"只用于一般現(xiàn)在時主語是第三人稱單數(shù)的情況,而"did"只用于一般過去時,不論主語是什么人稱和數(shù),都用"did".
3,一般疑問句:是指詢問事實的句子,此類句子必須用"yes",或"no"來回答.
如:Are you a student?Yes,I amNo,I'm not.Is she a doctor?Yes,she is.No,she isn't.Does he work in a hospital?Yes,he does./No,he doesn't.Did you watch TV yesterday evening?Yes,I did./No,I didn't.
☆注意☆小結(jié):
一般疑問句是在肯定句的基礎(chǔ)上,①把動詞be調(diào)到首位,其他照寫,末尾標(biāo)點符號變成問號即可.②沒有動詞be的句子則要在句首加上一個助動詞(do,does,did)再把緊跟在后面的動詞變回原形,末尾標(biāo)點符號變成問號即可.這三個助動詞也要根據(jù)人稱和時態(tài)來選擇,其中"does"只用于一般現(xiàn)在時主語是第三人稱單數(shù)的情況,而"did"只用于一般過去時,不論主語是什么人稱和數(shù),都用"did".一般疑問句有個重要的原則就是問和答要一致,即問句里的較好個單詞(助動詞)和簡略答句里的這個詞是一致的.
4,特殊疑問句:以特殊疑問詞(what,where,who,which,when,whose,why,how等)開頭引導(dǎo)的句子.此類句子應(yīng)該問什么就答什么,不能用"yes,no"來回答.如:
What is this?Where are you going?Who played football with you yesterday afternoon?When do you usually get up?Why do you like spring best?How are you?
☆注意☆小結(jié):
其中how又可以和其他一些形容詞連用組成特殊疑問詞組用來提問,如:how many(多少(數(shù)量)),how much(多少(錢)),how tall(多高),how long(多長),how big(多大),how heavy(多重)
例句:How many pencils do you have?How many girls can you see?
how many用來提問可數(shù)名詞的數(shù)量,主要有以上三種搭配,How many+名詞復(fù)數(shù)+do you have你有多少……How many+名詞復(fù)數(shù)+can you see你能看見多少……How many+名詞復(fù)數(shù)+are there…有多少……
no.7完全,縮略形式:
1、簡縮形式的變法:把倒數(shù)第二個字母,通常是元音字母變成'但are除外,are要把a打成'。Eg:he is=he's they are=they're
2、簡縮形式和完全形式的漢語意思相同。
3、把完全形式變成簡縮形式時,一定要注意較好個字母的大小變化。Eg:What is=What's
4、記住一個特殊變化;let's=let us讓我們(不要把'變成i)5、記?。簍hisis沒有簡縮形式this's(錯誤)
5.常見的縮略形式:
I'm=I am he's=he is she's=she is they're=they
are you're=you are there's=there is they're=they are
can't=can not don't=do not doesn't=does not
isn't=is not aren't=are not let's=let us
won't=will not I'll=I will wasn't=was not
