【正文】 方式狀語從句時間狀語從句從屬連詞: when, while, as, before, after, till/until, since, whenever, as soon as(一……就)……時態(tài):主將從現(xiàn),主情從現(xiàn),主祈從現(xiàn)一、When/while/as(當(dāng)…時候)區(qū)別:主句動作與從句動作發(fā)生的時間(同時/之前/之后);從句動詞(延續(xù)性/瞬時性)1)When: when引導(dǎo)時間狀語從句時表示“當(dāng)……的時候”,when既可以指時間段也可指時間點(diǎn),從句中既可用延續(xù)性動詞又可用瞬間性動詞,且動作既可和主句的動作同時發(fā)生又可在主句的動作之前或之后發(fā)生。. I will call you when I get there.. When I came home my wife was cooking dinner.. I will go home when the rain stops.. When I got to the airport,the guests had left.A)如果when引導(dǎo)的時間狀語從句的主語與主句主語相同,而從句的謂語又是be動詞時,那么從句中的主語和be可以省略。. When I came into the room (=When ing into the room), I found him lying there asleep.2)While while引導(dǎo)時間狀語從句時表示“當(dāng)……的時候”,它強(qiáng)調(diào)主句的動作與從句的動作同時持續(xù)地進(jìn)行,用于這一用法時while引導(dǎo)的時間狀語從句和主句中的謂語動詞必須是延續(xù)性動詞,或者強(qiáng)調(diào)主句的動作發(fā)生在從句動作的進(jìn)行過程中,此時主句中的謂語動詞通常是非延續(xù)性動詞。(while還可以表示對比,譯成“然而”,放在句首可以表示“雖然”). I met her while I was at school.. While I was sleeping, the UFO arrived.. We were doing our homework while it was raining outside.. Study while you study。. He jumps as he goes along.. As the wind rose the noise increased.【W(wǎng)hen, while , as 辨析】三者均可以表示“當(dāng)……時候”,如果主句表示的是短暫性動作,而從句表示的是延續(xù)性動作(主短從延),三者可以通用。 The plane had left when we got to the airport.(2) 表示帶有規(guī)律性的“每當(dāng)”,或者主從句動作有先后時,都只能用when.
