三 動(dòng)詞過(guò)去式

　　動(dòng)詞的過(guò)去式的構(gòu)成規(guī)則有:

　　A,規(guī)則動(dòng)詞

　　① 一般直接在動(dòng)詞的后面加ed:如 worked , learned , cleaned , visited

　　② 以e結(jié)尾的動(dòng)詞直接加d:如 lived , danced , used

　　③ 以輔音字母加y結(jié)尾的動(dòng)詞要改y為i再加ed(此類動(dòng)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(xiě)最后一個(gè)字母(此類動(dòng)詞較少)如 stopped

　　B,不規(guī)則動(dòng)詞(此類詞并無(wú)規(guī)則,須熟記)小學(xué)階段要記住以下動(dòng)詞的原形和過(guò)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

　　四 動(dòng)詞現(xiàn)在分詞詳解 動(dòng)詞的ing形式的構(gòu)成規(guī)則:

　　① 一般的直接在后面加上ing , 如doing , going , working , singing , eating

　　② 以e 結(jié)尾的動(dòng)詞,要先去e再加ing ,如having , writing

　　③ 雙寫(xiě)最后一個(gè)字母的(此類動(dòng)詞極少)有:running , swimming , sitting , getting

　　五 小學(xué)英語(yǔ)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(yǔ)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(dòng)詞后或介詞后，也就是說(shuō)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(gè))：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(gè))：me我 you你 him 他her她 it它 us我們 you你們 them他(她、它)們

　　六 句型專項(xiàng)歸類

　　1.肯定句:是指用肯定的語(yǔ)氣來(lái)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:

　　否定句主要是在肯定句的基礎(chǔ)上加上了否定詞 "not".有動(dòng)詞be的句子則"not"加在be后面,可縮寫(xiě)成"isn't,aren't",但am not 一般都分開(kāi)寫(xiě).沒(méi)有動(dòng)詞be的句子則要先在主要?jiǎng)釉~的前面加上一個(gè)助動(dòng)詞(do,does,did),然后在它后面加上"not",你也可以把它們縮寫(xiě)在一起如"don't , doesn't , didn't ).這三個(gè)助動(dòng)詞要根據(jù)人稱和時(shí)態(tài)來(lái)選擇,其中"does"只用于一般現(xiàn)在時(shí)主語(yǔ)是第三人稱單數(shù)的情況,而"did"只用于一般過(guò)去時(shí),不論主語(yǔ)是什么人稱和數(shù),都用"did" .
