新概念英语第三册第一课1句子结构~
The search proved difficult,for the puma was often observed at one place in the morning and at another place twenty miles away in the evening.
只看句子前半段：the search proved difficult这句结构有点看不懂.the search是主语,proved是谓语,一般过去时,而difficult是形容词,既不能做proved的对象,也不能修饰proved~
翻译成中文很简单,只是看不懂这样的结构.召唤达人解答
请注意！形容词只能修饰名词~副词修饰动词~如果要修饰proved~应该是proved difficultly！另外2楼的朋友~prove可以作为be动词使用么？还是有be动词的特性？请指教~另外1楼的朋友~你把proved difficult看做定语，修饰the search~那后面的谓语到哪里去找？
