(1) 形容词原级的用法

1. 句中只出现了一个人或物，没有比较对象时， 要用原级。 She has a new computer． 2. 修饰原级的词语有very, quite, rather, so, too等。如: Li Lei looks quite well. He is so strong that he can lift the big box.

3.表示A和B两者比较： ①程度相同, 用句型： A＋be＋as＋形容词原级＋as＋B Tom is as tall as John． This hat is as cheap as that one． ②A在程度上不如B, 用句型： A＋be＋not＋as／so＋形容词原级＋as＋B He is not as / so tall as I． The weather in Beijing is not as / so hot as that in Wuhan．

(2) 比较级的用法

1. 两者比较，说明“甲比乙更……一些”用句型： 甲＋be＋形容词的比较级＋than＋乙。 Mary is happier than Jane． Beijing is more beautiful than Wuhan． 注意：有时因为被比较的对象不需说出来，句中就会 省略 “than＋被比较的对象”。 Are you feeling better now﹖

5.“Which is＋比较级，A or B﹖” 表示“A和B哪个更……？” Which one is more popular, soccer or basketball﹖ 如果是人与人相比时，用Who代替Which。 Who is＋比较级，A or B﹖ 表示“A和B谁更……？” Who is happier, you or your father? 注意：A or B，只能用or不能用and。

6. “比较级＋than any other＋单数名词” 表示“比其他的任何……都……”。 He is better than any other student at English in the class． 他比班里任何一个学生的英语都好。 （暗指：他是最好的） 注意：any other后要加单数名词 This watch is more expensive than any other watch in the shop. 在这个店里，这只表比其他任何一个别的表都贵。 （这只表是最贵的）

7. “the＋比较级＋of the two” 表示“两个中比较……的”。 He is the better of the two． 8. “表示数量的词＋比较级” 表示“大……岁”“高……厘米” I am two years older than you. She is a head taller than I（me）.

9. 如果比较对象相同，常用that / those代替第二个比较对象。 The new words in Topic 2 are easier than those in Topic 3. The sky in Picture 1 is bluer than that in Picture 2.

(3) 形容词最高级的用法

1. A＋be＋the＋形容词最高级＋of / in… 表示三者或三者以上（人或物）的比较，其中有 一个在某一方面超过其他两个或几个时，用最高级。 Tom is the tallest of us all． This park is the most interesting in this city．
