我们老师说一定要用 it is difficult for sb to do
或者 sb have difficulties in doing
为你解答:
1.You are difficult to do... 这个句型不一定是错误的。看情况吧。
例如:You are difficult to get on/along with.(你这个人难以相处。)
2.It is diffcult for sb to do sth.(某人做某事有困难。)
例如:It is difficult for him to solve the problem.
3.have some difficulty in doing sth.(注意这里的difficulty是不可数名词)
例如:He had some difficulty in finding her house.
4.have some difficulties with sth(这里的difficulties是可数名词。)
例如:He had some difficulties with his pronounciation.

如果这样子写的话就成了＂你是困难的＂而其实你想表达的是＂做某事对于你来说是...的＂你们老师教的方法是用it做形式主语，to do不定式做真正的主语，避免头重脚轻的现象。

那如果我想说他们很自信 用they are confident 就是对的了
我想说他们难以忘记 用 they are hard to forget 就错了是嘛
你要搞清楚，形容词和主语之间的关系
如你举例的第一个，自信这个形容词是修饰他们的，所以可以用主系表结构来表达
而第二个例子中，形容词hard不是修饰主语they的，这句话hard修饰的是忘记他们这件事
再举个例子，比如说，学好英语对我们来说是必要的。
这句话不应该写成we are necessary to learn English well。主语We和形容词necessary 之间没有关系的
所以应该表达成It’s necessary for us to learn English well .

it是形式主语，真正的主语是后面的不定式，这是英语在表达上避免头重脚轻，固定的习惯用法
