He is more than happy about it.他对此事极为高兴。
以前只听说过more than比。。。多，怎么还可以放在这里？不太明白~能不能总结一下more than的用法？谢谢！

More than的用法好多种　简简单单的“more than”，用法可多呢！ 　　下面是些好例子： 　　●　A. “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. 　　●　D. 在“More...than...”中，肯定“more”后面的而否定“than”后面的，约等于“是……而不是……”如： 　　7)　　The difference between pure linguistics and applied linguistics is more apparent than real. 　　8)　　This book seems to be more a manual than a text. 　　9)　　Catherine is more diligent than intelli-gent. 　　10)　　Hearing the loud noise, the boy was more surprised than frightened. 　　●　E. “More than”或“More...than...”＋含“can”的分句时表示“否定意”，如： 　　11)　　That's more than I can do. 　　12)　　 Don't bite off more than you can chew. 　　13)　　In delivering his lecture, Jason makes sure not to include more things than the students can understand. 　　●　F. “No more...than...”表示“不……；不如……”，如： 　　14)　　 I can no more do that than anyone else. 　　15)　　A learner can no more obtain knowledge without reading than a farmer can get good harvest without ploughing.” 　　“No more…...than...”的语义，也可用“not any more than...”来取代，因此 15 可以变成 16。 　　16)　　A learner cannot... any more than ...”同样的， 17可以变成 18： 　　17)　　Dr Hu is no more a poet than Dr Wu is a philosopher. 　　18)　　 Dr Hu is not a poet any more than Dr Wu is a philosopher. 　　此外，“more than”也在一些惯用语中出现，如： 　　19)　　More offen than not （经常），people tend to pay attention to what they can take rather than what they can give. 　　20)　　All of us are more than a little concerned about（非常关心）the current economic problems. 　　总之，“more than”看似简单，其实很有内涵，味道隽永。
