Question

more than 他们分别 是什么词性,more是副词?than是连词?以下三句话中的more than 该怎么理解
We need more than material wealth to build our country
.I have known David for more 20 years.
More than one person has made this suggestion
morethan 是个连词?就不是“不仅仅”的意思,请问是more是做什么词 修饰 than,还是说英语中怎样的两个词可以组成类似的词组

Answer 1

more than 如果分开来看,more是形容词或副词,than用在比较级后面是介词.
但其实这是个复合词组,合起来是一个词性.它修饰名词时做形容词,修饰动词和形容词时是副词.
We need more than（形容词） material wealth to build our country
.I have known David for more than（副词） 20 years.
More than（形容词） one person has made this suggestion.
more than 的英文释义：
Adjective
1.(comparative of `much' used with mass nouns) a quantifier meaning greater in size or amount or extent or degree; "more land"; "more support"; "more rain fell"; "more than a gallon"
2.greater in number relative to something else; "more than one person stood up"
Adverb
1.comparing quantity or quality; "by the time she was 4 she was more than half her father's height"
