4、还有几个特殊的单词，它的比较级和最高级都是不规则的，如： many / much（原形） more（比较级） most（最高级） little / few（原形） less （比较级） least（最高级） good（原形） better（比较级） best（最高级） bad （原形） worse（比较级） worst（最高级） far （原形） further furthest（7）注意 比较的两者应该是互相对应的可比较的东西。 典型错误：My hair is longer than you.（我的头发比你更长。） 比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。 应该改为：
