请问英语中带more than的句子都是比较级吗?
好象有人说more than+名词,more than+数词之类的不算比较级,有什么规律可以总结吗?

比较级comparative degree 在英语中通常用下列方式表示的词：在形容词或副词前加more(如 more natural,more clearly )或加后缀 -er(newer,sooner ).典型的是指形容词或副词所表示的质、量或关系的增加.英语句子中,将比较两个主体的方法叫做“比较句型”.其中,像“A比B更……”的表达方式称为比较级.组成句子的方式是将形容词或副词变化成比较级的形态.
1.由“．．．as + 形容词 + as．．．”或“．．．as + 形容词 + 名词 + as．．．”构成
2.由“．．．not so (as) + 形容词 + as．．．”或“．．．not so (as) + 形容词 + 名词 + as．．．”构成
1.由“……形容词比较级 + than．．．”构成
2.由“．．．many / much more + 可数 / 不可数名词 + than．．．
1.“比较级 ＋ and + 比较级”或“more and more / less and less + 原级”结构表示“越来越……”的意思,与这类结构搭配的常用动词有grow,get,become等.
She felt herself becoming more and more nervous.
As the winter is drawing near,it's getting colder and colder.
2.the + 比较级 + of the two + 名词.
Jane is the taller of the two children in our family.
3.“the + 比较级……,the + 比较级……”,表示“越……,越……”.
The more magazines you sell,the more money you will get.
4.“否定 + 比较级” 相当于最高级.
— Wait until we get a satisfactory reply,will you?
— I couldn't agree more.The idea sounds great to me.
5.“a + 比较级 + 名词（than．．．）” 结构常出现在以never构成的完成时态的动词后面.
How beautifully she sings!I have never heard a better voice.
6.倍数表示法：．．．times as + 形容词原级 + as．．．；
．．．times + 形容词比较级 + than．．．；．．．times the + 性质名词 + of．．．.
The dining hall is three times as large as that one.
The dining hall is three times larger than that one.
The dining hall is three times the size of that one
more than
固定词组 ph.
1.多于
2.在...次以上
3.不只...
1.超出...的
more than 超出...的
2.不仅,不止;多.
319 more than不仅,不止;多于…

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.
