（求助）新概念新的语法问题，请教高手了

vampire

Modern alpinists try to climb mountains by a route which will give them
good sport, and the more difficult it is, the more highly it is
regarded.

句子用到THE MORE--- THE MORE===的句式。但是difficult 是adj.而highly是adv。在the more 的句式中比较不同词性是否可以，还有highly是修辞哪个词呢？谢谢

新概念4册的第三课matterhorn man中的句子

equipped in a manner which would make a modern climber shudder(v.不寒而栗) at the thought。

请问equipped in a manner 什么意思？in a manner什么成分，怎么用？

刘邦

It is legal to use  the words the part of speech of which are different such as a adjective and an adverb.

'equipped in a manner ' means 'prepared under some kind of meaning'

'in a manner' is used as a parenthesis.
