2) 有单词than要用比较级，如：This waiting room is more crowded than that one./That waiting room is less crowded than this one.

3) 在far, much, still, even, a little, a bit, a lot, any等词后面用形容词或副词的比较级，如：The traffic problem is much more serious these days.

4) 同一个形容词或副词的比较级并列使用，并且用and连接，表示程度的增加，解释‘越来越 ’，如：The snow is getting heavier and heavier.（单音节用-er and –er）

It is snowing more and more heavily.（多音节用more and more）

5)‘the +比较级，the +比较级’的结构，解释‘越 越 ’，前面的‘the +比较级’相当于一个条件状语从句，如：The more slowly the trains run on icy railways, the fewer accidents there will be.此句可以转换成：If the trains run more slowly on icy railways, there will be fewer accidents.

3 最高级

1）在三个或三个以上的事物之间之间进行比较时，用最高级，如：Which passenger s bag is the biggest, the lady’s, the young man’s or the girl’s?

2）有 in, among, of 等的表达语用最高级，如：The young man s bag is the biggest of the three. Among all the problems, the government thinks the traffic problem is the most serious one these days.

The waiting room for the passengers who will take the train Harmony is the most comfortable in this building.

2） 在定冠词 the 后用最高级，除非是‘the +比较级，the +比较级’的结构，如：The conductor

tries to give the passengers the best services while they are waiting for the train.

3） 副词最高级前可以省略定冠词 the ，如：This conductor works (the) hardest of all the

people who work for this railway station.

4） 在结构 one of 中， of 后面要用可数名词的复数，如果有形容词修饰名词，则要用形

容词的最高级，且最高级前一定要加定冠词 the ，如：This is one of the most

hard-working conductors I have ever seen.

5） 在‘第几大’‘第几高’等的表达语中，形容词要用最高级，如：Today is the third busiest

day for the station to receive so many passengers.

Things to remember:

在句型转换时，要注意形容词或副词的原级、比较级和最高级比较等级之间的互相转换，同级比较可以表示比较级的意义，比较级的形式也可以表示最高级的意义，如：

She is the most hard-working of all the conductors.

She is more hard-working than all of the other conductors.

Nobody is as hard-working as she is.
