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，hit，jump，knock等。Summary2)在本單元中,出現(xiàn)了以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。MarywashavingdinnerwhenIsawher.

Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.當(dāng)我看到Mary的時(shí)候她正在吃飯。當(dāng)他媽媽昨天早上到家的時(shí)候，這個(gè)男孩仍然在睡覺。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從句中必須是表示動(dòng)作或狀態(tài)的延續(xù)性動(dòng)詞。如：當(dāng)我們?cè)诒本┑臅r(shí)候天氣很好。在我出去的那段時(shí)間里她打電話來了。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)。如:當(dāng)我們?cè)谟斡镜臅r(shí)候，一個(gè)人偷走了我們的衣服。當(dāng)其他人在工作的時(shí)候不要這么大聲說話。Whilewewereswimmingsomeonestoleourclothes.Don’ttalksoloudwhileothersareworking.Summary
