more of 和more than的区别

more ofWhat he told us was more of an illusion than a reality.
more of在这里意为“更大程度上；更多地是… ”,后面一般跟than...,也可以省略than的部分.
但more of也可以表示一个群体里的更多的一部分,如More of my students want to do their homeworks by themselves.
more thanA.“More than＋名词”表示“多于……”、“非但……尤其是”如：
1) Modern science is more than a large amount of information.
2) Jason is more than a lecturer; he is a writer,too.
● B.“More than＋数词”含“以上”或“不止”之意,如：
3) I have known David for more than 20 years.
4) Let's carry out the test with more than the sample copy.
● C.“More than＋形容词”等于“很”或“非常”的意思,如：
5) In doing scientific experiments,one must be more than careful with the instruments.
6) I assure you I am more than glad to help you.
