come-coming

make-making

write-writing3)以重讀閉音節(jié)結(jié)尾的動(dòng)詞,如果末尾以一個(gè)輔音字母結(jié)尾,應(yīng)先雙寫這個(gè)字母,再加ing,x和w結(jié)尾的除外。如:get-getting

swim-swimming

box–boxing4)以字母y結(jié)尾的單詞,直接加ing。

如:carrying,playing,studying5)以字母ie結(jié)尾的動(dòng)詞,變ie為y,再加ing。

die→dying

lie→lying6)以元音字母加e結(jié)尾,或以e結(jié)尾,且e發(fā)音的動(dòng)詞,直接加-ing。

see-seeing

be-being2.使用進(jìn)行時(shí)態(tài)的注意事項(xiàng):

1)一些動(dòng)詞,如see,hear,love,like,know,remember,understand,have等表示感情、知覺(jué)和狀態(tài)的詞,一般不用于進(jìn)行時(shí)態(tài)。2)在there和here引起的句子中,常用一般現(xiàn)在時(shí)代替現(xiàn)在進(jìn)行時(shí)。

eg.Herecomesthebus.

Theregoesthebell.過(guò)去進(jìn)行時(shí)含義:表示過(guò)去某個(gè)時(shí)刻正在進(jìn)行的動(dòng)作。結(jié)構(gòu):was/were+doing例句：IwashavinganEnglishclassatthistimeyesterday.現(xiàn)在進(jìn)行時(shí)含義:表示現(xiàn)在正在進(jìn)行的動(dòng)作。結(jié)構(gòu)：is/am/are+doing例句：IamhavinganEnglishclass.

3.過(guò)去進(jìn)行時(shí)和現(xiàn)在進(jìn)行時(shí)的區(qū)別4.過(guò)去進(jìn)行時(shí)和一般過(guò)去時(shí)的區(qū)別過(guò)去進(jìn)行時(shí)一般過(guò)去時(shí)基本用法表示在過(guò)去的某一時(shí)刻或某一時(shí)間正在進(jìn)行的動(dòng)作。過(guò)去某個(gè)時(shí)間發(fā)生過(guò)的動(dòng)作或存在的狀態(tài)。結(jié)構(gòu)形式主語(yǔ)+was/were+V-ing形式主語(yǔ)+動(dòng)詞過(guò)去式時(shí)間狀語(yǔ)at7yesterday,atthattime,thistimelastnight等;when與while引導(dǎo)的時(shí)間狀語(yǔ)從句。yesterday,lastweek,in1993,once,before,afewdaysago等。友情提示表示一個(gè)過(guò)去正在進(jìn)行而可能尚未完成的動(dòng)作。表示過(guò)去已經(jīng)完成的動(dòng)作。1)過(guò)去進(jìn)行時(shí)表示過(guò)去正在進(jìn)行的動(dòng)作,而一般過(guò)去時(shí)則表示一個(gè)完整的動(dòng)作。如:Theywerewritingletterstotheirfriendslastnight.昨晚他們?cè)趯懶沤o他們的朋友。(沒(méi)有說(shuō)明信是否寫完)Theywroteletterstotheirfriendslastnight.他們昨晚寫了信給他們的朋友。(表達(dá)了他們已寫好的意思,整個(gè)寫的過(guò)程已完成。)講解：2)當(dāng)動(dòng)作延續(xù)較長(zhǎng)時(shí)間時(shí)或表示厭煩、贊美等感情色彩時(shí)，常用過(guò)去進(jìn)行時(shí)

表示。如：Hewasthinkingmoreofothersthanofhimself.他考慮別人的比考慮自己的多。(表示說(shuō)話者贊揚(yáng)的口氣)Theboywasalwaysmakingtroublethen.那時(shí)，他總是惹麻煩。(表示說(shuō)話者厭煩的口氣）when/while用法區(qū)別1)when指atorduringthetimethat,它既指時(shí)間點(diǎn)，也可指一段時(shí)間，while是duringthetimethat只表示一段時(shí)間，所以when引導(dǎo)的時(shí)間狀語(yǔ)從句中的動(dòng)詞可以是瞬間性動(dòng)詞，也可以是延續(xù)性動(dòng)詞，而while從句中的動(dòng)詞必須是延續(xù)性動(dòng)詞。Itwassnowingwhenwearrivedatthestation.Whileshewastyping,someoneknockedatthedoor.2)由when引導(dǎo)的時(shí)間狀語(yǔ)從句常用一般過(guò)去時(shí)，而主句用過(guò)去進(jìn)行時(shí)；但是在并不強(qiáng)調(diào)哪一個(gè)動(dòng)作持續(xù)時(shí)間更長(zhǎng)或者哪一個(gè)動(dòng)作是打斷性的(interruptive)行為的情況下，when引導(dǎo)的狀語(yǔ)從句也可以使用過(guò)去進(jìn)行時(shí)。如果強(qiáng)調(diào)從句和主句的動(dòng)作同時(shí)發(fā)生，兩句都用過(guò)去進(jìn)行時(shí)，則多用while引導(dǎo)從句。Hefinallyfellasleepwhen/whilethewindwasdyingdown.Theyweresinging
