口诀：比较级前用个be，比较级后用个“比”(than)。修饰比较级的词有a bit，a little，rather，much，far等。
比较级前可用a bit, a little, rather, some(肯定句及请求或建议的问句中),any(否定句或疑问句中)表示“稍稍，一点”;
用much, far, a great/good deal, a lot, lots, a good bit等表示“……得多”;
用still(只用于肯定句), even, yet等表示“更加”。
如：Can you move a little farther?你可以站稍远一点吗?
Do you feel any better today?你今天觉得好一点了吗?
Let’s go by car. It’s much cheaper. 咱们开车去。这样便宜得多。
There are far more people than we expected. 人比我们预计的多得多。
He is fat，but his brother is still fatter. 他很胖，但他哥哥更胖。
注：在作定语的比较级形容词前一般只用far或much。如：
That was a much/far easier job. 这是件容易得多的工作。
在修饰或代替复数可数名词的more前不可用much，而要用many。如：
I’ve made many more mistakes than you have.我出的错比你多得多。
