規(guī)則動(dòng)詞的過去式由“動(dòng)詞原形+-ed”構(gòu)成,具體變化有：
1.直接在詞尾加-ed.如:want—wanted,work—worked,need—needed,clean—cleaned
2.以不發(fā)音的e結(jié)尾的在詞尾加-d.如：like—liked,live—lived,use—used,move—moved
3.以一個(gè)元音字母加一個(gè)輔音字母結(jié)尾的重讀閉音節(jié)動(dòng)詞,先雙寫結(jié)尾的輔音字母,再加-ed.如：stop—stopped,trip—tripped
4.以輔音字母加y結(jié)尾的動(dòng)詞,先把y變成i,再加-ed.如：study—studied,carry—carried,hurry—hurried,marry—married
不規(guī)則動(dòng)詞的過去式見課本后的不規(guī)則動(dòng)詞表.大體上歸納有以下六條記憶法：
1.以t結(jié)尾的詞,過去式與原形相同.如：put—put,let—let,cut—cut,beat—beat
2.以d結(jié)尾的詞,把d變成t.如:build—built,lend—lent,send—sent,spend—spent
3.以n結(jié)尾的詞,在詞后加t.如：mean—meant,burn—burnt,learn—learnt
4.以ow / aw結(jié)尾的詞,把ow / aw變成ew.如：blow—blew,draw—drew,know—knew,grow—grew
5.含有雙寫字母的詞,將雙寫改為單寫,在詞尾加t.如：keep—kept,sleep—slept,feel—felt,smell—smelt
6.含有元音字母o / i的詞,將o / i變成a.如：sing—sang,give—gave,sit—sat,drink—drank
規(guī)則動(dòng)詞詞尾加-ed有三種讀音：
1.在清輔音后讀作[t].如：asked,helped,watched,stopped
2在濁輔音和元音后讀作[d].如：enjoyed,studied,moved,called
3.在t / d后讀作[id].如：wanted,needed
現(xiàn)在分詞的構(gòu)成方法如下 ：一般情況下,直接在動(dòng)詞原形后面加 -ing.
going asking finding working being seeing printing raining standing studying speaking spelling
以不發(fā)音的-e 結(jié)尾的動(dòng)詞,去-e ,再加-ing.coming taking firing encircling writing becoming breathing leaving
閉音節(jié)的單音節(jié)詞,或以重讀閉音節(jié)結(jié)尾的多音節(jié)詞,這些詞的末尾只有一個(gè)輔音字母時(shí),雙寫這個(gè)輔音字母,再加 -ing.
sitting running getting cutting stopping beginning planning permitting
一般現(xiàn)在時(shí)主語單三人稱時(shí)的動(dòng)詞變化
①在一般現(xiàn)在時(shí)中,當(dāng)主語為第三人稱單數(shù)時(shí),動(dòng)詞要用“s”型（即第三人稱單數(shù)形式）.
②所謂動(dòng)詞“s”型的構(gòu)成,可按名詞變復(fù)數(shù)的規(guī)則來記,即：
i）在動(dòng)詞尾直接加 s.如：
play—plays,want—wants,work—works,know—knows,help—helps,get—gets
ii）以字母s、x、ch或o結(jié)尾的動(dòng)詞加-es；如：
guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch—watches,catch—catches
iii）以輔音字母＋y結(jié)尾的動(dòng)詞,先變y為i,再加-es.如：
study—studies,carry—carries,fly—flies,worry—worries
③④強(qiáng)調(diào)如何將主語是第三人稱單數(shù)的肯定句變?yōu)榉穸ê鸵蓡柧?現(xiàn)舉例說明（用劃線部分來說明順口溜）：
1）His mother works in a factory．
His mother doesn’t work in a factory．
Does his mother work in a factory?
2）Mr Li teaches us English．
Mr Li doesn’t teach us English．
Does Mr Li teach you English?
3）My brother studies maths well．
My brother doesn't study maths well．
Does your brother study maths well?
