原因状语从句
1 because, since 和 as 的区别
（1）because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：
“Why didn’t he come?” “Because he was ill.” “他为什么没来?”“因为他病了。”
We must stay at home because it rained. 我们必须呆在家，因为下雨了。
（2）since 较弱，指双方都明确的原因或众所周知的原因，泽为“既然”，侧重主句，从句表示显然的或已知的理由。
Since you don't like it, I'll put it away. 既然你不喜欢，我就把它放在一边。
Since everybody is here, let’s begin our class. 既然每个人都在，我们开始上课吧。
（3）as “由于，鉴于”，指客观事实，语气比since 弱，略口语化，常与since互换使用。
As there was no answer, I wrote again.
鉴于没回复，我又写了一封信。
语气
位置
意义
because
最强
前或后
“因为”，表示客观因果关系
since
较强
前
“既然”，把众人所知的事实当作理由，较为正式?
as

总结：
2、because习惯上不与so连用
　　汉语习惯上说“因为…所以…”，但英语习惯上却不能将 so与because 连用：
　　正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.
　　误：Because it was raining, so we stayed at home. 因为下雨，所以我们呆在家里。
3、because VS because of
because 后加句子，引导原因状语从句。
例如： I do it because I like it. 我做这件事情因为我喜欢。
because of 后加名词，代词，动名词。
The football match will be put off because of the bad weather.
因为坏天气，足球赛将会延期。
两者可以互换
He can't come because he is ill.
==He can't come because of his illness. 他因病不能来。
I said nothing about it because his wife was there.
== I said nothing about it because of his wife's being there
因为他妻子在那儿，我对此事只字未提。

As young students, you have many dreams. These dreams can be very big, such as winning the Nobel Prize, they can also be small, such as becoming one of the best students in your class.
Once you find a dream, what do you do with it? Do you ever try to make your dreams real?
Andrew Matthews, an Australian writer, tells us that making your dreams real is life's biggest challenge. You may think you're not very good at some school subjects, or that it's impossible for you to become a writer. Those kinds of ideas stop you from realizing your dream.
In fact, everyone can realize his dream. The first thing you must do is to remember what your dream is. Don't let it leave your heart. Keeping telling yourself what you want every day and then your dream will come true faster. You should know that a big dream is, in fact, made up of many small dreams.
You must also never give up your dream. There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will help you to get better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book.
As you get closer to dream, it may change a little. This is good as you have the chance to learn some-thing more useful and find new hobbies.
