A. “More than＋名词”表示“多于……”、“非但……尤其是”如：

● 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.
● F. “No more...than...”表示“不……；不如……”,如：

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：

20) All of us are more than a little concerned about（非常关心）the current economic problems.
