翻译为英文是：Does peter jump higher than tom 这句话是将两者进行比较，是比较级。

用比较级形容词+than+比较成分，所以原级high后面加er。表示比...更。比较级的句子还有：

①He is younger than me.他比我年轻。

②I am a better swimmer than he（him）.我游泳比他好。

③Lesson One is much easier than Lesson Two.第一课比第二课容易得多。

④I got up earlier than my mother this morning.我今天早晨起床比我妈妈还早。
