四级英语语法精解（三）

        修饰语的选用根据其所表达的意思而定，如⑥，⑩。
        3）比较级结构与其它结构的区别
        如⑧中形容词修饰语more than a month与比较级结构的区别，⑨中most 与the most的区别。
       
        3． 比较级应对策略
       
        1）如果选项中有比较级结构，则该题则为比较级考查题，可根据比较级使用规则选择正确答案。
        2）比较级修饰语应注意more than 或as…as结构之前。
        3）注意比较结构的完整性，要么是more than 结构，要么是as/so …as 结构，或是the more …., the more ….的句型。
        4）注意结构的各种变体：
        结构内出现名词时的结构可以是as old a car, as many /much/few/little …as。
        5）如果有比较 对象的选择应注意比较对象的一致性和互不包容性。如：
        His English is better than anyone else's in his class.
       
        4． 自我测试
