(1)much/a little/ a bit/ a lot / slightly. She is much taller than me. I am a little shorter than my mother. (2) 具体数量. My sister is ten years younger than me. (3) any/ no/ even/ some/ still Do you feel any better today?

(2) 动名词/从句  Skiing is more exciting than skating. 5、as……as中间用原级。 as……as… (与…一样) not as(so)……as (与…不一样) 6、表示倍数的词或其他程度副词做修饰语,放在as的前面。 She can read twice as fast as you do. 7、、比较级与最高级可以转换,意思不变。如: She is taller than any other girl in Class5.=She is the tallest girl in Class5. 8、比较的事物只能是同一级别的。如: My hair is longer than Mary's. His shirt is more expensive than mine. 9、如果比较对象相同,可用 that\those代替第二个比较对象 。如: The weather in Shanghai is better than that in Wuhan.  10、比较级的特殊搭配。 1)“比较级+and+比较级”表示“越来越……”eg: He becomes fatter and fatter.        2)“The +比较级…,the +比较级”表示 “越……,越……”The more ,the better. 3)表示两者中”较……“时,用the + 形容词比较级 + of 短语来表达。 He is the taller of the two. 4)More than 不仅仅是,超过 ; Less than 不到 5)more or less 差不多  The work is more or less finished.工作差不多完成了。 【当堂练习】 一、写出下列形容词或副词的比较级。 old__________  young________  tall_______  long________  short________  strong________  big________  small_______ fat_________    thin__________  heavy______  quiet__________ nice_________  good_________  beautiful______________ long___________  fat__________ slow__________  far__________  short__________ good__________ 二、根据句意填入单词的正确形式。 1.Miss Chen is __________ _________than Mr. Wang.
