1、Because引導(dǎo)的原因狀語從句引導(dǎo)原因狀語從句的從屬連詞主要的有because,as,since,for,seeing(that),now(that),considering(that),inthat等:Thewoollyshrankbecauseitwaswashedbadly.毛衣因洗得不得法而縮水。Ican’tgettosleepbecauseofthenoiseoutside.由于外面聲音嘈雜我睡不著。Since[As]we’venomoney,wecan’tbuyit.由于我們沒錢,我們無法購買它。Seeingth
2、atit’sraining,we’dbetterstayindoors.既然外邊在下雨,我們最好待在室內(nèi)。Nowthatyouarehere,you’dbetterstay.你既然來了,最好還是留下吧(既來之,則安之)。because語勢最強(qiáng),表示不知道的原因用because,即說話人認(rèn)為聽話人不知道。因此because從句是全句最重要的部分,通常被放置于主語之后;有時也放在主句之前。—YouwanttoknowwhyIamleaving?—IamleavingbecauseIamfedup.(2)回答why提出的問題,只能用
3、because。A:Whycan’tIgo?B:Becauseyouaretooyoung.(3)在強(qiáng)調(diào)句中強(qiáng)調(diào)原因,只能用because引導(dǎo)。It’sbecauseheiskindthatwelikehim.(4)because從句可用作表語。這是主語一般都是it,this,that。Thisisbecausetheearthistravelingaroundthesun.(5)關(guān)于not…because結(jié)構(gòu)該結(jié)構(gòu)中的否定詞有時否定主句,有時否定從句,一般要根據(jù)句子的意思作出正確合乎邏輯的理解。若not否定主句,最好在bec
4、ause之前用逗號,否則會引起歧義,如下句在沒有特定上下文時就有兩種解釋:Ididn’tgobecauseIwasafraid.我沒有去是因為怕。/我不是因為怕才去。不過若because之前有just修飾,一般認(rèn)為not是否定從句的:Youshouldn’tgetangryjustbecausesomepeoplespeakillofyou.你不要因為有人說你壞話而生氣。(6)because習(xí)慣上不與so連用。漢語習(xí)慣上說“因為…所以…”,但英語習(xí)慣上卻不能將so與because連用:例:因為下雨,所以我們呆在家里。正:Bec
5、auseitwasraining,westayedathome.Itwasraining,sowestayedathome.誤:Becauseitwasraining,sowestayedathome.(7)because從句與becauseof短語的轉(zhuǎn)換Because引導(dǎo)的原因狀語從句有時可與becauseof短語轉(zhuǎn)換,becauseof后加的原因可以為好或壞,但最正規(guī)的還是because。Hecan’tcomebecauseheisill.Hecan’tcomebecauseofhisillness.他因病不能來。Isai
