要看后面是具體什么人稱、數(shù)量、時(shí)態(tài)以及結(jié)構(gòu)是怎樣的。后面跟什么樣的就用對應(yīng)的的動(dòng)詞形式,如果because of后面直接跟動(dòng)詞,就應(yīng)該用動(dòng)名詞形式,這時(shí)候動(dòng)名詞本質(zhì)上等效于名詞。
1. because 表示的是必然的因果關(guān)系,語氣最強(qiáng),通常放在主句之后,若需強(qiáng)調(diào)則放在主句之前……
2. 通常用來回答 why提出的問題。如:
A:Why can't you do it now?你為什么不現(xiàn)在就做呢?
B:Because I'm too busy. 因?yàn)槲姨Α?/p>
3. 可引導(dǎo)從句作表語。如:
It is because he is foolish. 那是因?yàn)樗懒恕?/p>
4. 可用于強(qiáng)調(diào)句。如:
It is because he is honest that we likehim. 是因?yàn)樗\實(shí)我們才喜歡他。
5. not…because…這一結(jié)構(gòu)中的 not 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,否則會引起歧義,如下句在沒有特定上下文時(shí)就有兩種解釋。如:
I didn't go because I was afraid.
(1) 我沒有去是因?yàn)榕隆?/p>
(2) 我不是因?yàn)榕虏湃ァ?/p>
不過若because之前有just修飾,一般認(rèn)為not 是否定從句而不是主句。如:
You shouldn't get angry just because some people speakill of you. 你不要因?yàn)橛腥苏f你壞話而生氣。
He was not readyto believe something just because Aristotle said so. 他并不只是因?yàn)閬喞锸慷嗟抡f過如何如何,就輕易相信它。
6. 表示“…的原因是因?yàn)椤边@一意義時(shí),一般要用下面這樣的句型。如:
The reason why he can't come is that he is tired. 他不能來是因?yàn)樗哿恕?/p>
在這一結(jié)構(gòu)中盡管不少人認(rèn)為可將that改用 because, 但也有不少人反對這一用法,學(xué)生宜慎用。
7. 漢語習(xí)慣上說“因?yàn)椤浴?,但在英語里卻不能將 so與because 連用。如:
因?yàn)橄掠?,所以我們呆在家里?/p>
正:Because it was raining, we stayed at home.
正:It was raining, so we stayed at home.
誤:Because it was raining, so we stayed at home.
8. 用于 because of, 意為“因?yàn)椤?,用法注意?/p>
(1) 是復(fù)合介詞,其后可接名詞、代詞、動(dòng)名詞以及由關(guān)系代詞型的 what 所引導(dǎo)的從句等。如:
He couldn't come because of illness. 他因病不能來。
I said nothing about it, because of his wife'sbeing there. 因?yàn)樗拮釉谀莾海覍Υ耸轮蛔治刺帷?/p>
He knew shewas crying because of what he had said. 他知道她哭是因?yàn)樗f的話。
