She cooks as well as her mother does. 否定：not+as/so+adj/adv+as, 不如He didnt study as/so hard as his sister.This dictionary is not as/so useful as you think.若有倍数词或其他程度副词（twice, three times, half, a quarter）须位于第一个as之前。Your bike is twice as expensive as mine.This bridge is three times as long as that one.2. prefer 作及物动词使用,通常意思是“更喜欢,宁愿”.1.prefer + 名词/动名词/不定式例：I prefer some apples. I prefer having(to have) some apples.我更喜欢吃苹果.prefer somebody to do something 宁愿某人做某事2.My daddy prefers me not to swim in that river because its too dangerous.我爸爸宁愿我不要去那条河里游泳因为那太危险了. 3.prefer A to B 在 A 和 B 中更喜欢 A例：I prefer green tea to coffee.绿茶和咖啡比较起来我更喜欢绿茶.
