1

Couldyoupleasecleanyourroom？情態(tài)動(dòng)詞could1.用法和句式結(jié)構(gòu)【難點(diǎn)提示】在表示請(qǐng)求或表示請(qǐng)求許可的句型中,could不是can的過去式,而是表示委婉語(yǔ)氣,答語(yǔ)中用can/can’t而不用could/couldn’t。2.其他用法Unit

Whydon’tyoutalktoyourparents？1.until意為“直到”,引導(dǎo)時(shí)間狀語(yǔ)從句(1)當(dāng)主句是肯定句時(shí),主句中的謂語(yǔ)動(dòng)詞必須是延續(xù)性動(dòng)詞。(2)not...until...意為“直到……才……”,主句的謂語(yǔ)動(dòng)詞一般是非延續(xù)性動(dòng)詞,它所表示的動(dòng)作直到所表示的時(shí)間才發(fā)生。(3)如果主句為一般將來(lái)時(shí),從句要用一般現(xiàn)在時(shí)表示將來(lái)。2.althoughalthough是連詞,意思是“雖然,盡管”,引導(dǎo)讓步狀語(yǔ)從句,可以放在主句前面,也可以放在主句后面。【難點(diǎn)提示】在一個(gè)句子中,用了although就不能再用but,但可用yet;用了but就不能用although。3.so

that(1)sothat意為“以便;為了”,常用來(lái)引導(dǎo)目的狀語(yǔ)從句,一般放在主句后,且不用逗號(hào)隔開。目的狀語(yǔ)從句常表示動(dòng)機(jī)(即一種可能性),因此從句中常帶有can,could,would,should等情態(tài)動(dòng)詞。(2)當(dāng)sothat引導(dǎo)的從句的主語(yǔ)和主句主語(yǔ)一致時(shí),可用inorderto或不定式短語(yǔ)替換,其意義基本不變。Unit3Whatwereyoudoingwhentherainstormcame？過去進(jìn)行時(shí)1.過去進(jìn)行時(shí)的用法(1)表示過去某一時(shí)刻正在進(jìn)行的動(dòng)作。(2)表示過去某段時(shí)間內(nèi)一直在進(jìn)行的動(dòng)作。2.與過去進(jìn)行時(shí)連用的時(shí)間狀語(yǔ)常用的時(shí)間狀語(yǔ)有:at8o’clockyesterdaymorning,atthistimeyesterday,atthetimeof...,when及while引導(dǎo)的時(shí)間狀語(yǔ)從句。3.when

和while的區(qū)別連詞用法when引導(dǎo)的時(shí)間狀語(yǔ)從句既可以表示時(shí)間點(diǎn),也可以表示時(shí)間段,從句中謂語(yǔ)動(dòng)詞可以是非延續(xù)性動(dòng)詞,也可以是延續(xù)性動(dòng)詞while引導(dǎo)的時(shí)間狀語(yǔ)從句表示某個(gè)時(shí)間段,從句謂語(yǔ)動(dòng)詞必須用延續(xù)性動(dòng)詞,且多用進(jìn)行時(shí)態(tài)Whenshesawhim,hewassittinginaself-drivingcar.當(dāng)她看到他時(shí),他正坐在一輛無(wú)人駕駛汽車?yán)?。When/WhileTomwasdoinghishomework,thetelephonerang.當(dāng)湯姆做作業(yè)時(shí),電話鈴響了。Whilemybrotherwaslisteningtomusic,mysisterwasdrawingapicturelastnight.昨晚我哥哥在聽音樂時(shí),我妹妹在畫畫。Unit
