I am taller than Tom. My dress is more beautiful than hers. 2. 最高级 表示三者或三者以上 (人或事物 ) 的比较, 其中有一个在某一方面超过其他几个时, 用最高级。最高级的前面一般要加定冠词 the, 后面可带 of ( in )短语来说明比较的 范围。 如： She is the youngest in the class. Jason is the tallest of the three. Whose handwriting is the best of all? 3.在形容词比较级前还可用 much, even, still, a little 来修饰, 表示“ …… 的多”, “甚至 …… ”, “更 …… ”, “ …… 一些”。如： This city is much more beautiful than before. She’s a little more outgoing than me. It’s a little colder today. 4.“比较级＋and＋比较级” 意为“越来越 …… ” 。 多音节比较级用“more and more＋形容词原级”形式。 如： It’s getting worse and worse . The group became more and more popular. 5. “Which / Who is + 比较级 …？” 比较A、B两事物, 问其中哪一个较 …… 时 用此句型。如： Which T-shirt is nicer, this one or that one? Who is more active, Mary or Kate? Which one is more popular among students, going to concerts or going to movies? 6. 使用形容词比较级时需注意以下几点： 1) than后面接代词时, 一般要用主格形式， 但在口语中也可使用宾格形式。 如： My brother is taller than I / me. 2) 当需要表示一方超过另一方的程度时， 可以用much, a lot, a little, a bit, even, still 等来修饰形容词比较级。注意: 比较级不 能用very, so, too, quite等修饰。如： He is much more serious than Sam. 3) 形容词比较级后面往往用连词than连接 另一个比较的人或事物, 但在上下文明确 的情况下, 形容词比较级可单独使用。如： My sister is tall, but my aunt is taller . 我姐姐个子高, 但我姑姑个子更高。 用形容词的适当形式填空 1.
