三 動詞過去式

　　動詞的過去式的構成規則有:

　　A,規則動詞

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

　�、� 以e結尾的動詞直接加d:如 lived , danced , used

　�、� 以輔音字母加y結尾的動詞要改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 雙寫最后一個字母(此類動詞較少)如 stopped

　　B,不規則動詞(此類詞并無規則,須熟記)小學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

　　四 動詞現在分詞詳解 動詞的ing形式的構成規則:

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

　�、� 以e 結尾的動詞,要先去e再加ing ,如having , writing

　　③ 雙寫最后一個字母的(此類動詞極少)有:running , swimming , sitting , getting

　　五 小學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

　　六 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:

　　否定句主要是在肯定句的基礎上加上了否定詞 "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人稱和時態來選擇,其中"does"只用于一般現在時主語是第三人稱單數的情況,而"did"只用于一般過去時,不論主語是什么人稱和數,都用"did" .
