Who dances better, you or your sister? 2. 比谁就“than”谁,有“than”就用比较级。Yao Ming is taller than Tom.Tom is _ (short) than Yao Ming.Tom jumps higher than Jack. 3. 注意同类相比,比较对象要一致4. 当than 前后的动词相同时,后面的动词通常用助动词代替或省略不写。You know more English than your father (does).5. 要加强语气,可以在比较级前用这些词修饰,much,even, a lot, a little, a bit, far,still等；修饰形容词或副词原级的词: very, quiet, too, much too, a little, a little bit,kind of,so, pretty等。 E.g: Alice sings well. Mike sings _than she. （甚至更好）6. 相同的比较级用and 连接表示“越来越在前加more构成比较级的,表示“越来越”,只用and连接more。 He becomes healthier and healthier.The girl becomes more and more beautiful. 7. “the 比,the 比”,表示“越就越”The more you exercise, the healthier you will be.The more careful you are, the fewer mistakes you will make.8.表示“两者中较的一个”,用the +比较级 +of the two结构。E.g: The boy in blue is the taller of the two boys.9.不和自己比,具有最高级的含义。Mike is the tallest in his class. (改为同义句)Mike is _ than _ _ student in his class. Mike is _ than_ _ in his class.Mike is _ than _ _ students in his class.10.表示不及另一方时,用“less+原级+than”E.g: (1). Larry is healthier than Sally. =Sally is less healthy than Larry.(2). Larry plays tennis better than Huang Lei. But he is less hard-working than Huang Lei.So they can help each other.11.在比较句式中,为了避免重复,常用the one, that, those等代替前面出现的名词。E.g: In winter,the weather in Harbin is colder than that in Shenzhen.12. 表示“倍数”时,用“倍数+比较级+than” 结构E.g:This river is three times longer than that one. 课堂练习（难点巩固）Step 2 Exercising1.
