the question is so easy that we can answer it.
the question is easy for us to answer.
请帮我解释关于这两个句子的语法知识点.越详细越好,我会对答的好的追加分数.
还有就是请说明一下两个句子结尾处的 answer it.answer.
为什么要这么说

第一个句型是so……that……,意思是如此……以至于……,例句：我太累了,以至于走不动了：I am so tired that I can't walk on.（注意：that后跟从句）可以替换的句型有too……to……,他的意思也是如此……以至于……,但他只能用在否定句.例句：我太累了,以至于走不动了：I am too tired to walk on.他太小了以至于不能上学：He is too young to go to school.（注意：to后跟动词短语,用在否定句）
还可以用not enough……to替换：还是刚才的例句：I am not active enough to walk on.He is not old enough to go to school.（注意：to后跟动词短语,enough前跟想要表达意思相反的词,如tired－active,young－enough）
第二个句型结构：it＋be＋形容词＋for＋人＋to＋do 例句：it is hard to work out the problem.
