能否的英语短语

be able to

to do sth;be able to do sth;in a position to do sth;be capable of doing sth;

就是because+句子=because of+短语的意思是因为+基本句子=由于；因为+短语 。because后面接句子；because of后面接非句子，即短语或者非谓语。 如：1.I did not answer the telephone at that time,because I was washing my clothes then.(去掉because，后半部分仍然是个句子） 2.I did not see you because of his arrival.(去掉because of，后半部分不是句子）

to do sth.
