A 和 B 必须是可比较的同类事物; than 是连接词，引出比较的对象 (B)。 形容词比较级作表语（在系动词如 be, look, seem, become, feel 等后面）或定语（放在名词前）。副词比较级修饰动词、形容词、其他副词或整个句子，通常放在被修饰词之前（但 enough 除外）。 eg: 1.My brother is taller than me. 2.He found a more comfortable chair. 3. Please speak more slowly. Explanation Grammar Focus 3a Read the sentences and notice the comparatives in bold. Find more examples in Section A. There are more activities this year.
