it is no pleasure looking through these any longer.其中的look为什么要加ing
问题描述：
it is no pleasure looking through these any longer.其中的look为什么要加ing
答
It is no pleasure looking through these any longer.
原因是 looking 是当动名词用的。
句子的 “looking through these...” 代表主语的 "it ".
it is no pleasure = looking through these... is no pleasure.
答
no pleasure doing sth 做某事没有意思。
答
这个句子的形式主语是it，而真正的主语是looking through these，也就是等于：
(主语Looking through these) (谓语is) (宾语no pleasure) (状语any longer)
作为主语只能用非谓语动词，这里就是用look的动名词形式。
答
it is no pleasure 后面就加动名词啊
答
此句解释为：走马观花是没有任何乐趣的,因为自然是一种需要真正去历练的东西.
这里looking through...,动名词做后置定语,修饰pleasure.动名词作定语表主动.此句也可改定语从句
