问题描述：
because与because of 有什么区别
比如：we all cheered( )the Olympic Games were held in Beijing.选择because becsuse of
答
because+句子
because of+Vdoing/n.
例：he didn't go to school because he was ill.
he didn't go to school because of his illness.
because是连词
because of是介词短语
答
because后面接的是句子要有主谓宾的，而because of 后面要接的是短语！！！！！因为the Olympic Games were held in Beijing有主谓宾是句子而不是短语，所以应该用because不是because of ！！！！
答
because 后面跟的是句子
because of后面跟的是名词
你给的例句里面就应该填because
答
楼上的正解
because 是连词所以必须跟句子在后面，而because of是介词，后面必须跟名词（词组）/动名词（词组）
举个例子给你：
I love you not because of who you are, but because I know who I am when I am with you.
希望能帮你更好的理解两个词之间的差别。
