此处more 可以是副词,如果上文有“练的对象”出现,比如English,它也可以做名词或代词..
For English,If you practice more,then you can make progress.
也有形容词的时候
If you practice some more English ,then you can make progress.
下面是详细一点的解释
1.作副词.常放在某些双音节或多音节形容词、副词前构成比较级.如:
This car is more expensive than that one.
2.作形容词.单独作 many ,much 的比较级,意为“更多……”,在句子中通常修饰复数名词或不可数名词,作定语.如:
She has more books than I.
He bought more milk than you.
注意:这种说法可以用 many ,much 来表明“多得多”,即“ many more + 可数名词”或“ much more + 不可数名词”.如:
You have many more friends than he has.
3.相当于形容词.用于“ two ( three...) / some / many / a few / a little / any / no...more + 名词”结构中,意为“又、再、还”,表示数量有所增加.如:
She ate two more oranges.
Would you like some / a little more bread
4.作名词或代词.通常有两种意思和用法:
( 1 )表示“更多或较多的数量”,在句中多作主语或宾语.如:
There is some milk in the cup.There is more in that one.
( 2 )表示“额外的数量、另外的一些”,用在数词或 a few ,some ,any ,a little 等之后.如:
Give me a little more.
I'd like to have some more.
注意:more 作名词使用时,实际上是因为 more 后面的名词很明显而省略了,所以这时人们常把它看作名词使用.实际也是代词了.
5.“ no more = not ...any more ”意为“不再”.如:
Time lost will return no more.= Time lost won't return any more.
6.more and more 常用在名词前,意为“越来越多”.如果用在形容词、副词(双音节或多音节词)前时,也意为“越来越……”.如:
There are more and more buildings in our city.
The little girl is becoming more and more beautiful.
7.more than 相当于 over ,常放在数词前,意为“多于、超过”.如:
I have taught here for more than ( over ) ten years.
8.“ once more = once again ”表示“再一次”.如:
Once more / again,please.
9.more or less 相当于 about ,意为“或多或少,差不多,大约”.如:
— How far is your home from school 你家离学校有多远?
— It's 2 kilometres,more or less.差不多两公里.
