Because 可不可以单独成句.给出几个例子更好 I m soooooo confused~天杀的考试啊!

ecause [bi'kɔ:z]
conj.因为, 由于
because是一个连词,所谓连词,就是连接前后两个完整的句子,起一个连接作用了,所以它自己不可以单独成句
一般它可以放在句子开头或者中间,如
Because he got up late, he missed the bus. = He missed the bus because he got up late.(because连接了前面he missed the bus和后面he got up late这两个完整句子,起连词作用）~~~
