Jane works as hard as Amy. Your house is not as / so big as mine. Tom doesn’t run as / so fast as his brother. 2. 原级前可用very,quite等词修饰。如: I’m very tired. Helen plays the guitar quite well. ◆ 比较级 构成 形容词和副词的比较级的构成分为规则变化和不规则变化两种,具体构成见课本P114。 用法 1. (1) 当两者(人或事物)之间进行比较,其中一方“较……”或“更……一些”时常用比较级,常用句型“主语 + be / 行为动词 + 形容词 / 副词比较级 + than + 比较对象.”。当than后为人称代词时,可用其主格形式或宾格形式。如: Alice is funnier than Molly. Dale studies harder than I / me. Dale is more handsome than Peter. (2) 当询问两者中谁更 / 哪一个更 / 什么更……时,常用句型“Who / Which / What + be + 形容词比较级, A or B?”和“Who / Which / What + 行为动词 + 副词比较级, A or B?”。如: Which is better, the red pen or the black pen? Who dances better, you or your sister? 2. 形容词和副词的比较级可以单独使用。如: It was quieter outside. Try to do better next time. 3. 形容词和副词的比较级前可以用a little,much,a lot等词语修饰。如: The red hat is a little / much cheaper t
