wonder + if 引导的宾语从句

这是一个动词固定搭配。
vt. 想知道...; 想弄明白...

if、whether 有何区别

ifwhether都含有是否的意思。

两者各自的用法都极其丰富,也导致很多初学者大受困惑,即在哪些情况下可以用或不可以用其中之一。

在详细罗列具体区别之前,为避免进一步困惑大家,我们先化繁为简,直接给出如下记忆量最小的结论。

规则一
if仅在引导部分名词性从句时,才有是否的含义,其中包括引导后置主语从句及引导部分宾语从句。
规则二
whether可以引导几乎全部名词性从句(除否定宾语从句外),即在满足规则一后可用if的情况下,大多也可用whether。只是whether更正式,而if更口语化、更常见。
引导状语从句

两者皆可引导状语从句,但无任何相似之处。

if引导条件状语从句,表示如果...; 即使...; 每当

whether引导让步状语从句,表示不管...; 无论...,从句中通常用一般现代时代替将来时。

be. + because 引导的表语从句

这是一个固定搭配。

because 详解

because意为因为。表示的是必然的因果关系,语气较强。

通常与引导的内容一起放在主句之后,若需进一步强调则可放在主句之前。

用于回答 why 提出的问题

A: Why can't you do it now? 你为什么不现在就做呢?

B: Because I'm too busy. 因为我太忙。
引导表语从句
  • It is because he is foolish. 那是因为他太蠢了。
引导原因状语从句
  • I didn't buy it because it was too expensive. 我没有买是因为它太贵了。
用于强调句

提取状语作为强调句的被强调成份是一种常规用法。

because更是大量用于该句式,以至几乎成了固定搭配,特此单独作为一种用法。

  • It is because he is honest that we like him. 是因为他诚实我们才喜欢他。
注意! 此时because引导的从句虽然在词法位置上位于系动词之后,但它并不具备表明抽象主语it的某一特征,解释为状语从句而不是表语从句更能说明成份功能。当然,实际不必深纠,理解掌握即可。
because of

详见 “because 与 because of 的区别" 。

not...because...

这一结构中的not有时否定动词中心语,有时否定动词中心语 + 状语,一般要根据句子的意思作出正确或合乎逻辑的理解。

not只否定动词中心语,最好在because之前用逗号,否则会引起歧义。

如下句在没有特定上下文时就有两种解释:

I didn't go [because I was afraid].

我没有去是因为怕。

I didn't [go because I was afraid].

我不是因为怕才去。
注意! 不仅仅是because,所有其它连词引导的后置状语也存在同样的问题。enpuz 星游引擎在分析类似句子时,将会根据语料概率返回最大可能的分析结果,可能此时会偏离使用者的已有理解。建议合理使用逗号,让分析结果更加符合预期。
just修饰后

because之前有just修饰,一般认为not是否定从句而不是主句。

  • You shouldn't get angry just because some people speak ill of you. 你不要因为有人说你坏话而生气。
  • He was not ready to believe something just because Aristotle said so. 他并不只是因为亚里士多德说过如何如何,就轻易相信它。

不能为了解决歧义而在所有because前带上just,毕竟语气上稍有改变。初学者在口语应用时容易过度使用这一搭配。

错误场景: 原因是因为...

在表示...的原因是因为...这一意义时,一般要用下面这样的句型:

  • The reason why he can't come is that he is tired. 他不能来是因为他累了。

通常不能将that改用because,否则会产生能被理解但结构略显怪异的“中式英语"。

错误场景: 因为...所以...

汉语习惯上说因为...所以...,但在英语里却不能将sobecause连用。

因为下雨,所以我们呆在家里。

正: Because it was raining, we stayed at home.

正: It was raining, so we stayed at home.

误: Because it was raining, so we stayed at home.

because、because of 有何区别

because是连词,其后接句子。

引导原因状语从句
  • I didn't buy it because it was too expensive. 我没有买是因为它太贵了。
引导表语从句

It is because he loves you. 那是因为他爱你。

because of是复合介词,其后接可作宾语成份的名词、代词、动名词、what开头的从句等。

作状语成份
  • He is here because of you (that). 他为你(那事)而来这里。
  • He lost his job because of his age. 由于年龄关系他失去了工作。
  • He couldn't come because of illness. 他因病不能来。
更多
  • We said nothing about it, because of his wife's being there. 因为他妻子在那儿,我们对此只字未提。
  • He knew she was crying because of what he had said. 他知道她哭是因为他说的话。
because of之后可接what开头的从句,但不能接that从句或没有引导词的句子。

误:He didn't come because of he was ill.

误:He didn't come because of that he was ill.

正:He didn't come because he was ill.

正:He didn't come because of his illness.

作表语成份
  • It is just because of money. 那只是因为钱的原因。
  • That was because of his sickness. 那是因为他生病的原因。

because、since、as 及 for 的区别

because可用来回答why提出的问题;可以引导表语从句;可用于强调句等,而其余三者则不行。

because表示的是必然的因果关系,语气最强,通常放在主句之后,若需强调则放在主句之前。

sinceas所表示的原因是人们已知的,是对已知事实提供理由,而不表示直接原因。它们引导的从句通常放在主句之前,有时也放在主句之后。

  • As he wasn't ready in time, we went without him. 因他未及时准备好,我们没等他就先走了。
  • Since we have no money, it's no good thinking about a holiday. 既然我们没有钱,考虑度假有什么用。

至于for, 它是并列连词(其余三者为从属连词),它有时可表示因果关系 (通常要放在主句之后,且可与because换用);有时不表示因果关系,而是对前面分句内容的解释或推断 (也要放在主句之后,但不能与because换用)。试比较:

  • The ground is wet, [for/because] it rained last night. 地面是湿的,因为昨晚下过雨。
  • It must have rained last night, for the ground is wet this morning. 昨晚一定下过雨,你看今天早上地面是湿的。

  • Many people are on horses while one man is not because he doesn't know how to ride one.
  • I wonder if it 's because I haven't been able to be outdoors for so long.
  • There was no baby shower for the mother because it turns out she was not pregnant.
  • This is because in the early days of radio, those who reported the news were expected to speak excellent English.
