because和because of的意思都是:因为,由于。
但是在用法上又有不同。
because:后加从句。
比如:She doesn't go to school because she is ill.
她没来上学因为她生病了。
在这句话中。
she is ill就是从句。所以because后面就是接从句。
而再来看because of。
because of:后加代词/名词/动词的ing形式。
还是拿刚才那句话来比较。用because of来代替后。就是:
She doesn't go to school because of her illness.
同样的一个意思。接连的却不同。
her illness是名词。
这就可以说明。because of后接代词/名词/动词的ing形式。
because是连词,引导从句,because of是复合介词,后面加名词或相当于名词的词、代词、动名词、what 从句等。例如:
1、Please be brief because I am in a hurry. 我有急事,请长话短说。
2、I did not go to the cinema because of the intense cold. 我因为严寒没出去看电影。
3、I didn't buy it because it was too expensive. 我没有买是因为它太贵了。
4、He is here because of you (that). 他为你(那事)而来这里。
5、He lost his job because of his age. 由于年龄关系他失去了工作。
判断断语还是句子的标准:
单独取出because或because of的内容,如果有动词(也就是谓语)的是句子,如果没有则是断语。
例如:
1、I didn't go to school because i am ill. am是谓语(动词)
2、 I didn't go to school because of my illness. my illness是短语(名词)
