as a result of和because of的区别.

ecause of后面跟动名词或者名词或者名词短语.表示“因为...”====强调原因====
Because of you ,I lost this job.因为你,我丢了工作!
单用because后面就是加句子
as a result of 副词.因此,由于；作为…的结果 后面加名词和短语.====强调结果====
Some of the uncertainty comes as a result of competition from places like India and China.
有些不确定性是来自象印度和中国这些地方的竞争的结果
你的例句：：（Because of ）his being late again,he lost his job and had to stay at home.
这个句子中his being late again因为他又迟到了（很明显是原因）,造成了他“he lost his job and had to stay at home”丢了工作赋闲在家.
如果用as a result of 来替换,那就是：
He was late again as a resuit of losing his job!
他又迟到了,结果是丢了工作!
