5、各種從屬連詞的含義及用法比較；及用法比較；選when？還是as比較像，選while吧！崩潰ING！Back to school連接詞類別作 用例 句asas 表示“當(dāng)?shù)臅r(shí)候”，往往和 when/ while 通用，但它著重強(qiáng)調(diào)主句與從句的動(dòng)作或事情同時(shí)或幾乎同時(shí)發(fā)生。1.She came up as I was cooking.（同時(shí)）2.The runners started as the gun went off.（幾乎同時(shí)）when既可以表示在某一點(diǎn)的時(shí)候，又可表示在某一段時(shí)間內(nèi)。when可以和延續(xù)性動(dòng)詞連用，也可以和短暫性動(dòng)詞連用；而while和as只能和延續(xù)性動(dòng)詞連用 ;when從句

6、的謂語動(dòng)詞可以在主句謂語動(dòng)作之前、之后或同時(shí)發(fā)生；while和as從句的謂語動(dòng)作必須是和主句謂語動(dòng)作同時(shí)發(fā)生。 1.When we were at school, we went to the library every day.（在一段時(shí)間內(nèi)）2.Sorry，I was out when you called me（call為短暫性動(dòng)詞）對(duì)不起，你打電話時(shí)我剛好外出了。 3. When I got to the airport，the guests had left（got to后發(fā)生）當(dāng)我趕到飛機(jī)場(chǎng)時(shí)，客人們已經(jīng)離開了。 whilewhile 意思是“當(dāng)?shù)臅r(shí)候”或“在某一段時(shí)間里”。從句動(dòng)

7、作和主句動(dòng)作同時(shí)發(fā)生，且從句動(dòng)作為延續(xù)性動(dòng)詞時(shí)，when，while，as都可使用。 主句中的動(dòng)作或事情是在從句中的動(dòng)作或事情的進(jìn)展過程中發(fā)生，從句中的動(dòng)詞一般要用延續(xù)性動(dòng)詞。1.When While As we were dancing，a stranger came in（dance為延續(xù)性動(dòng)詞）。2.Please dont talk so loud while others are working. 延續(xù)性動(dòng)詞表達(dá)的動(dòng)作能夠延續(xù)，如：延續(xù)性動(dòng)詞表達(dá)的動(dòng)作能夠延續(xù)，如：keep保存，維持；保存，維持；walk走路；走路；read 閱讀等；非延續(xù)性動(dòng)詞也稱瞬間動(dòng)詞，所表達(dá)的動(dòng)作不能夠延續(xù)。如

8、：閱讀等；非延續(xù)性動(dòng)詞也稱瞬間動(dòng)詞，所表達(dá)的動(dòng)作不能夠延續(xù)。如：hear聽到；聽到；return 歸還；歸還；see看見?？匆?。對(duì)比： 2. I had just stepped out of the bathroom and was busily drying myself with a towel _ I heard the steps. A. while B. when C. since D. after答案： B解析：下劃線處表示 “正在這時(shí)， 突然”， 四個(gè)選項(xiàng)中只有when可以表示此含義。Back to school課后作業(yè)狀語從句有九種，狀語從句有九種，時(shí)地原因條狀補(bǔ)，時(shí)地原因條狀補(bǔ)，目比結(jié)果方讓步，目比結(jié)果方讓步，連詞引導(dǎo)各不同；連詞引導(dǎo)各不同；主句通常前面走，主句通常前面走，連詞引導(dǎo)緊隨后，
