  小升初英語考點(diǎn):一般過去時(shí)變化規(guī)則講解

  1.一般過去時(shí)表示過去某個(gè)時(shí)間發(fā)生的動(dòng)作或存在的狀態(tài),常和表示過去的時(shí)間狀語連用。

  一般過去時(shí)也表示過去經(jīng)常或反復(fù)發(fā)生的動(dòng)作。

  2.Be動(dòng)詞在一般過去時(shí)中的變化:

  ⑴am 和is在一般過去時(shí)中變?yōu)閣as。(was not=wasn't)

  ⑵are在一般過去時(shí)中變?yōu)閣ere。(were not=weren't)

 、菐в衱as或were的句子,其否定、疑問的變化和is, am, are一樣,即否定句在was或were后加not,一般疑問句把was或were調(diào)到句首。

  3.句中沒有be動(dòng)詞的一般過去時(shí)的句子

  否定句:didn't +動(dòng)詞原形,如:Jim didn't go home yesterday.

  一般疑問句:在句首加did,句子中的動(dòng)詞過去式變回原形。如:Did Jim go home yesterday?

  特殊疑問句:

 、乓蓡栐~+did+主語+動(dòng)詞原形?如:What did Jim do yesterday?

  ⑵疑問詞當(dāng)主語時(shí):疑問詞+動(dòng)詞過去式?如:Who went to home yesterday?

  動(dòng)詞過去式變化規(guī)則:

  1.一般在動(dòng)詞末尾加-ed,如:pull-pulled, cook-cooked

  2.結(jié)尾是e加d,如:taste-tasted

  3.末尾只有一個(gè)元音字母和一個(gè)輔音字母的重讀閉音節(jié),應(yīng)雙寫末尾的輔音字母,再加-ed,如:stop-stopped

  4.以"輔音字母+y"結(jié)尾的,變y為i, 再加-ed,如:study-studied

  5.不規(guī)則動(dòng)詞過去式:

  am/is-was, are-were, do-did, see-saw, say-said, give-gave, get-got, go-went, come-came, have-had, eat-ate, take-took, run-ran, sing-sang, put-put, make-made, read-read, write-wrote, draw-drew, drink-drank, fly-flew, ride-rode, speak-spoke, sweep-swept, swim-swam, sit-sat
