Unit 13 The mystery of the Moonstone
troubled by the loss of such a valuable jewel, rachel’s mother hires the famous detective sergeant cuff to investigate the theft.由于這么昂貴的珠寶的丟失,rachel的母親雇傭了一個著名偵探sergeant cuff去調查這起偷竊事件。【點撥】 “troubled by the loss of such a valuable jewel”是分詞在句首作原因狀語。分詞作狀語放在句子開頭,除表示原因之外有時表示時間或條件:e.g. reading attentively,he forgot the time for lunch.由于在專心讀書,他忘了吃午飯的時間。(原因)reading carefully,he found something he had not known before.他仔細讀書時,發現了一些從前不知道的東西。(時間)
reading carefully,you'll learn something new.只要你仔細閱讀,你會學到一些新的東西。(條件)
現在分詞與過去分詞作狀語的區別:
現在分詞做狀語與過去分詞做狀語的最主要區別在于兩者與所修飾的主語的主動與被動關系的區別。
1)現在分詞作狀語時,分詞的動作就是句子主語的動作,它們之間的關系是主動關系。
e.g. not knowing what to do, he went to his parents for help.
由于不知如何辦是好,他去找父母幫忙。
2)過去分詞作狀語時,分詞表示的動作是句子主語承受的動作,它們之間的關系是被動關系。
e.g. given more attention, the trees could have grown better.
如果對這些樹多關心一些,它們本來會長得更好。
e.g. faced with difficulties, we must try to overcome them.
在遇到困難的時候,我們必須設法克服。
he finds out that they are not real entertainers, but religious followers of the moon god. 他發現他們不是真正的藝人,而是月亮神的宗教追隨者。【點撥】 not...but… “不是…而是…”并列連詞,連接兩個并列成分。當連詞or, either...or, neither...nor, not only...but also, not...but, there be 等連接兩個并列not...but主語時,謂語的數與最靠近它的主語保持一致。 e.g. not he but jane and mary have been invited to the party.【點撥】entertainer 名詞,“藝人,表演者” entertainment名詞,“娛樂,文娛表演”entertaining 形容詞,“使人愉快的;有趣的”entertain 動詞,“給人快樂;使人感興趣”“招待;款待”did dr candy or godfrey take the moonstone as revenge for loss of face?
