知之為知之，不知為不知，是知也。以下是小編為大家搜索整理的英語專四原因狀語從句考點(diǎn)練習(xí)，希望能給大家?guī)韼椭?更多精彩內(nèi)容請(qǐng)及時(shí)關(guān)注我們應(yīng)屆畢業(yè)生考試網(wǎng)!
引導(dǎo)原因狀語從句的從屬連詞有because(因?yàn)?, as(由于), since(既然), now(that)(既然), when(既然), seeing (that) (由于，鑒于), considering (that)(考慮到), given (that) (考慮到)等。
一、引導(dǎo)原因狀語從句的從屬連詞主要的有because,for,in that,for the reason that;as,seeing (that), seeing as;since;now (that); considering (that)等：The woolly shrank because it was washed badly. 毛衣因?yàn)橄礈斓姆椒ú缓枚s水。I can’t get to sleep because of the noise outside. 由于外面聲音嘈雜我睡不著。Since [As] we’ve no money, we can’t buy it. 由于我們沒錢，我們不能購買它。Seeing that it’s raining, we’d better stay indoors. 既然外邊在下雨，我們最好待在室內(nèi)。Now that you are here, you’d better stay. 你既然來了，最好還是留下吧(既來之，則安之)�！咀ⅰ砍陨咸岬降拇蠹冶容^熟悉的引導(dǎo)原因狀語從句的從屬連詞外，when有時(shí)也可引導(dǎo)原因狀語從句(when表示“既然”)I won’t tell you when you won’t listen. 既然你不想聽，那我就不告訴你了。
二、關(guān)于not…because結(jié)構(gòu)該結(jié)構(gòu)中的否定詞有時(shí)否定主句，有時(shí)否定從句，一般要根據(jù)句子的意思作出正確或合乎邏輯的理解。若not否定主句，最好在because之前用逗號(hào)，否則會(huì)引起歧義，如下句在沒有特定上下文時(shí)就有兩種解釋：I didn’t go because I was afraid. 我沒有去是因?yàn)榕隆? 我不是因?yàn)榕虏湃サ摹２贿^若because之前有just修飾，一般認(rèn)為not 是否定從句的：You shouldn’t get angry just because some people speak ill of you. 你不要因?yàn)橛腥苏f你壞話而生氣。
三、because不能與so連用漢語習(xí)慣上說“因?yàn)?hellip;所以…”，但英語習(xí)慣上卻不能將 so與because 連用：因?yàn)橄掠�，所以我們得呆在家里。正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.誤：Because it was raining, so we stayed at home.
四、because從句與 because of短語的轉(zhuǎn)換Because引導(dǎo)的原因狀語從句有時(shí)可與because of 短語轉(zhuǎn)換，because of后加的原因可以為好或壞但最正規(guī)的還是because He can’t come because he is ill. / He can’t come because of his illness. 他因病不能來。I said nothing about it because his wife was there. / I said nothing about it because of his wife’s being there. 因?yàn)樗拮釉谀莾海覍?duì)此事只字未提。比較：because, since, as和for1) 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。 當(dāng)原因是顯而易見的或已為人們所知，就用as或 since。I didn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2) for雖然表示原因，但因語氣比because弱得多，是可說可不說的話，只能位于主句之后。這時(shí)，for是并列連詞，如果不是因果關(guān)系，而是對(duì)前面主語內(nèi)容加以解釋或推斷時(shí)，只能用for。He is absent today, because / for he is ill.He must be ill, for he is absent today.
