You can usebecause,as,since, orfor to give an explanation for something.because is the commonest of these, and is used when answering a question beginning with 'why?'.You can useas orsince instead ofbecause to introduce a clause containing a reason for something, especially in writing....a note about The National Portrait Gallery, as the word 'Gallery' can be misleading... Since the juice is quite strong, you should always dilute it. In stories,for is sometimes used to explain or justify something.He seemed to be in need of company, for he suddenly went back into the house. Note thatbecause is a conjunction, and is used to link two ideas within one sentence.I'm unsocial, because of my deafness.
because, as, since 或者 for 都可以用来给出解释。because 最常用，用来回答以 why 开头的疑问句。as 或 since 可以代替 because 引导原因从句，尤其是在书面语中：a note about The National Portrait Gallery, as the word ‘Gallery’ can be misleading（对 The National Portrait Gallery 的注释，因为 Gallery 一词容易令人误解），Since the juice is quite strong, you should always dilute it（这种果汁太浓，所以必须加以稀释）。在故事中，for有时用于解释或论证：He seemed to be in need of company, for he suddenly went back into the house（他看起来需要陪伴，因为他突然回到了屋里）。注意，because 是连词，用来连接一个句子中的两个观点：I'm unsocial, because of my deafness（我耳朵聋，所以不善交际）。

1. 因为：如: <>(Yesterday)中运用了弦乐四重奏; <>(Eleanor Rigby)中运用了弦乐八重奏; <>(you've go hide your love away)中运用了长笛; <>(because)中运用了古钢琴; <>(Penny lane)中运用了短号;

2. 原因：1 避免状语从句的多次出现,尤其是时间(when)、原因(because)、让步(although)等从句,平时要强化练习,培养学生有意识地向分词或独立主格转换,因为非谓语动词,尤其是分词,是中国考生不太主动运用的,

3. 从句：第二个原因当然是第一个原因的深入,因为中国多是独子,写成了S4,有一个原因状语从句(because)在里面.

conj.(连词)

because, as, for, since

这四个词都可以作连词引导一个表示原因的状语从句。其区别是：

1.because是从属连词,引导的原因状语从句指的是自然、直接的原因,主句表示必然的因果关系,而原因构成句子的主要部分,是句子的重点。另外,because引导的从句多放在句末,但有时也可放在句首,这种情况往往是为了强调。

2.如果原因很明显或已为人们所知,或不如句子的其余部分重要,就用as或since,since比as更正式一些,这两个词都为从属连词,常译为“由于,既然”,语气比because轻。as和since引导的句子多放在整个句子的开头,偶尔它们引导的(特别是since引导的)句子也可以放在后面。since作为理由有“不好”或“勉强”的含意;而as只将既成事实作为理由,并不含有“不好”或“勉强”的意味。

3.for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作推断性的补充说明或解释,不表示直接原因。for较正式,很少用于口语,一般用于书面语,前面一般多用逗号。

because of, due to

这两个短语都可表示“因为”“由于”，其区别在于：because of主要引导状语，偶尔导表语；而due to则主要引导表语，偶尔引导状语。

because of, for the sake of

这两个短语的词义并不相同，because of指原因或理由，常译为“因为”；而for the sake of则指利益或目的，常

译为“为了”。

as，because，for，since

这些连词均含有“因为”之意。

as从属连词，语意较because, since弱，着重在主句，所表示的原因或理由是“附带的”。

because从属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以回答why提出的问题。

for并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。

since语意比because弱，但比as强，一般用于表示“由于大家已知的事实”。

conj.(连词)

因为他病了,所以他没去上学。

误 because he was ill, so he didn't go to school.

正 because he was ill, he didn't go to school.

析 在英语中,如果原因状语从句用because引导,主句就不能用so; 反之,主句用so,从句就不用because。

• ☆ 1300年左右进入英语，直接源自古法语的par cause。
