问题解答:

我来补答
这是个固定句型
主语+ be+ 形容词+ to do(主动式,因为句子的主语是不定式的逻辑宾语)
再如:
The question is easy to answer
The sentence is difficult to translate.
The apple is good to eat.
The math problem is easy to work out

再问: 可是问题不是被解决吗,不就应该用to be solved吗,solved也可以表示被动,为什么不能用啊?
再答: 我说了, 此句型中的主语是不定式的逻辑宾语!!! 你看: The problem is easy to solve. =It is easy to solve the problem.
