because可以引导主语从句吗

在少数情况和少数结构中，because 可以引导主语从句，这尤其见于以下几类句型：

句型一：(Just) because…doesn’t mean…

Just because it’s red doesn’t mean it’s cherry-flavored. 仅仅是红色的并不意味着它有樱桃味。

(Just) because I object to his promotion doesn’t mean I’m vindictive. 我反对提拔他并不意味我是在报复他。

Just because I’m lending you my dress for tonight doesn’t mean you can borrow it whenever you want to. 如果因为我夜晚把裙子借给你，你就以为随时可以借来穿，那你就错了。

Just because you’re older than me doesn’t mean you can tell me what to do. 只是因为你比我年纪大，这并不意味着你可以对我指手划脚。

句型二：(Just) because…is no reason…

Because you have words with your wife is no reason to smash up things. 你和你的妻子吵架并不能成为摔东西的理由。

Because they are dead languages is no reason why they should be ignored in academic circles. 不能因为它们是死的语言而就在学术界忽视它们。

句型三：(Just) because…doesn’t make…

Just because something has always been done a certain way does not make it right. 仅仅因为老是以某种方式做事并不意味着这么做就是对的。

句型四：其他结构或搭配

Just because all nation states are motivated by self-interest does not preclude that self-interest having a moral component. 所有的民族国家都为自身的利益所驱使，这一点并不排除那种自身利益也包含合乎道德的成分。

because 引导主语从句的用法可以有多种不同角度的理解和解释：

一是可理解为省略了it。如：

Just because it’s red, it doesn’t mean it’s cherry-flavored. 仅仅是红色的并不意味着它有樱桃味。

二是可理解为对 the fact that 的误用。如：

Just because he’s late doesn’t mean he’s had an accident. 他迟到了并不等于他就有意外了。

=The fact that he’s late doesn’t mean he’s had an accident.

三是将其理解为状语形式的主语，Quirk认为这类because属于状语形式的主语（adverbial forms as subject），所给例句是：

Because Sally wants to leave doesn’t mean that we have to. 不能说因为萨利要走因而我们也得走。

与此类似的，Quirk还列举了以下例句（均属状语形式的主语）：

Slowly is exactly how he speaks. 慢条斯里地讲话恰恰就是他讲话的方式。

Out on the lake will be splendid. 到外面的湖上会很不错。

Whenever you are ready will be fine. 你什么时候准备好都没关系。

Will after the show be soon enough? 看完戏后时间还来得及吗？
