形容词的比较级和最高级.doc

形容词的比较级和最高级一形容词比较等级形式变化英语中，绝大多数形容词比较等级有三个：原级，比较级和最高级。 形容词比较等级形式变化有规则的和不规则的两种。规则变化如下:单音节：1）单音节词末尾加-er（比较级），-est（最高级） 2）单音节如以e结尾，只加-r（比较级），-st（最高级） 3）重读闭音节单音节词如末尾只有一个辅音字母，须先双写这个辅音字母，再加-er（比较级），-est（最高级） 双音节：4）一般情况下，双音节和多音节形容词在前面加单词more和most。 5）少数以-y，-er，ow，-ble结尾的双音节词，末尾加-er（比较级），-est（最高级）。以-y结尾的词，如-y前是辅音字母，则变y为-i，再加-er和-est。以-e结尾的词只加-r和-st。 不规则变化 （口诀：两好三坏两多一少一远）原级 比较级 最高级 二形容词原级，比较级和最高级的用法：一般说来，两者间作比较用比较级，三者或三者以上作比较用最高级原级：1. 表示比较的双方相等，用”asas”结构，表示“前者像后者一样”，即A + be + as + 形容词原级 + as + B.e.g. John is as tall as his brother.2. 表示比较的双方不相等，用”not as/soas”结构，表示“前者不如后者”，即A + be + not as + 形容词原级 + as + B.e.g. John is not as tall as his brother.比较级当把一个人或物同另外一个人或物比较时，就需要用到形容词比较级。其结构是：A + be + 形容词比较级 + than + B.e.g. Jack is taller than Alex, but Alex is heavier than Jack最高级三者或者三者以上的人或物进行比较时，需要使用形容词的最高级。其结构是：A + be + the 形容词最高级 + of / in + 比较范围.
