"Much"和"much more"都可以用来构成比较级,但是它们的使用方式略有不同。
"Much"用于形容词和副词的比较级中,表示程度更高的意思,通常放在比较级前面。例如:
This book is much better than the one I read last week.
I ran much faster today than I did yesterday.
"Much more"用于表示程度更高的比较中,放在比较级前面,或者放在被比较的两个事物之间。例如:
This book is much more interesting than the one I read last week.
I ran much more quickly today than I did yesterday.
The new car is much more expensive than the old one.
需要注意的是,如果形容词或副词已经用了比较级形式,就不需要再加"much"或"much more"了。例如:
She is happier than she was yesterday. (不需要说"She is much happier than she was yesterday.")
He runs faster than I do. (不需要说"He runs much faster than I do.")
比较级通常用于比较两个事物或人之间的差异,用法是在形容词或副词的基础形式后面加上“-er”。例如:
She is taller than me.
This book is more interesting than that one.
在表示更多的差异时,可以用“much”或“much more”,例如:
He is much taller than me.
This book is much more interesting than that one.
但是,有些形容词和副词比较级的形式不同,需要特别注意。例如:
good -> better
bad -> worse
far -> farther / further
much -> more
many -> more
little -> less
few -> fewer
因此,具体用法要根据具体的形容词或副词来决定。
比较级什么时候用much或者much more的规则如下:
如果形容词的音节是三个或三个以上,就在前面加上more比较级,例如more beautiful, more difficult。
如果形容词的音节是两个或以下,就在后面加上er比较级,例如bigger, faster。
有些形容词是不规则的,比如good-better, bad-worse。
much是用来修饰形容词比较级的,加深程度,表示“…得多”,例如much better更好。
much more也可以修饰形容词比较级,但是更强调差异,表示“…得多得多”,例如much more beautiful美丽得多得多。
使用"much"和"much more"的情况取决于所比较的两个事物或性质的不同程度。
"much"用于比较级的形容词和副词:
形容词比较级:例如,"much bigger"(更大)。
副词比较级:例如,"much faster"(更快)。
"much more"用于比较级的名词和动词短语:
名词比较级:例如,"much more money"(更多的钱)。
动词短语比较级:例如,"much more difficult"(更困难)。
需要注意的是,"much"通常用于否定句或疑问句,而"much more"用于肯定句中。
例如:
"This book is much better than that one."(这本书比那本书好得多。)
"She speaks much more fluently now."(她现在说得流利多了。)
"He doesn't like it much."(他不太喜欢。)
"Is it much colder today?"(今天冷得多吗?)
