Among the twins, Ella is a little quieter than Emma. 解析than引导比较，a little修饰比较级表轻微差异。 2. Peter plays the flute better than Chen Jie. 解析well不规则比较级better。 3. This music festival is not as wonderful as last year’s. 解析not as…as 不如……，单元核心否定原级。 4. I work as hard as my deskmate. 解析as…as原级比较，中间副词原级hard。 5. She speaks much more clearly than other classmates. 解析多音节副词比较级more clearly，much强化程度。 6. My little sister is not as outgoing as me. 解析形容词原级用于not as…as结构。 ## 六、情景写作参考范文 ### 短文1 Ella and Emma are twin sisters. Ella is a little quieter than Emma, but Emma is more outgoing.
