本句中when引導(dǎo)定語從句，其先行詞為incident。關(guān)系副詞when的先行詞一般是表時(shí)間的名詞，如:HecamelastnightwhenIwasout.但有時(shí)并不直接是表時(shí)間的名詞，如：In1921EinsteinwontheNobelPrize,andwashonoredinGermanyuntiltheriseofNazismwhenhewasdrivenfromGermanybecausehewasaJew.1921年愛因斯坦獲得了諾貝爾獎(jiǎng)，他在德國很受尊敬。納粹上臺(tái)后由于他是猶太人而被趕出了德國。4.AccordingtoaUNreport,….accordingto根據(jù),據(jù)…說

AccordingtoJohn,thebankclosesat4p.m.Eachmanwillbepaidaccordingtohisability.dodo渡渡鳥ListeningDoDo鳥是一種不會(huì)飛的鳥，僅產(chǎn)于毛里求斯肥。擁有肥胖的身子和巨大的嘴。

16世紀(jì)后期，歐洲殖民者來到了毛里求斯。不會(huì)飛又跑不快的DoDo鳥很快成為歐洲人來到島上后主要的食物來源。人們開始大量的濫捕濫殺可憐的DoDo鳥，有時(shí)每天可以捕殺到幾千只到上萬只。由于過度的捕殺,很快島上DoDo鳥便得越來越少。1681年，最后一只DoDo鳥被殘忍的殺害后，從此，地球上再也見不到這種東西了，除非是在博物館的圖片中。
