延續(xù)性動(dòng)詞指動(dòng)作可以延續(xù)一段時(shí)間,而不是瞬間結(jié)束。

如:work、study、drink、eat等。

非延續(xù)性動(dòng)詞指動(dòng)作極為短暫，瞬間結(jié)束。

如:start、begin、die等。(2)在本單元中,出現(xiàn)了由when和while引導(dǎo)的時(shí)間狀語從句when表示“當(dāng)……的時(shí)候”。從句中既可用延續(xù)性動(dòng)詞,又可用非延續(xù)性動(dòng)詞,這些動(dòng)詞既可以表示動(dòng)作,又可表示狀態(tài)。從句中的動(dòng)作既可以和主句的動(dòng)作同時(shí)發(fā)生,又可在主句的動(dòng)作之前或之后發(fā)生。e.g.MarywashavingdinnerwhenIsawher.

Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.語法聚焦由when和while引導(dǎo)的時(shí)間狀語從句while表示“在……的時(shí)候”、“在……期間”。它強(qiáng)調(diào)主句的動(dòng)作與從句的動(dòng)作同時(shí)發(fā)生或主句的動(dòng)作發(fā)生在從句的動(dòng)作過程中。while從句中必須用表示動(dòng)作或狀態(tài)的延續(xù)性動(dòng)詞。e.g.

TheweatherwasfinewhilewewereinBeijing.

ShecalledwhileIwasout.如果主句的動(dòng)作在從句的動(dòng)作過程中發(fā)生，從句常用進(jìn)行時(shí)。e.g.Whilewewereswimming,someonestoleourclothes.Don’ttalksoloudlywhileothersareworking.【總結(jié)】(1)when可指時(shí)間點(diǎn),又可指時(shí)間段,從句中可用延續(xù)性動(dòng)詞,也可用非延續(xù)性動(dòng)詞。(2)while總是指一個(gè)時(shí)間段,從句中必須用延續(xù)性動(dòng)詞。語法聚焦John

外面沒有光亮，感覺就像半夜一樣。此句中介詞with表示一種伴隨的狀況，同時(shí)還包含著某種因果關(guān)系，表示“因某種狀況的存在而導(dǎo)致……”，因此可譯作“由于；因?yàn)椤钡?。e.g.Ican’tworkwithallthatnoisegoingon.由于那噪音響著，我無法工作。Languagepoints2.Ben’sdad...whilehismomwasmakingsuretheflashlightsandradiowereworking.在他媽媽確認(rèn)手電筒和收音機(jī)都能正常使用的同時(shí)，本的爸爸……(1)此句中的連詞while的意思是“當(dāng)……的時(shí)候；和……同時(shí)”，while還可以表示“然而；但（是）”之意，用來說明或強(qiáng)調(diào)兩種事情或情形的不同。e.g.TomisactiveandoutgoingwhilehissisterRosaisshyandquiet.

我的手表是防水的——這就是說即便在水里它也會(huì)正常運(yùn)轉(zhuǎn)。
