特殊用法：only to

表示与预料相反的结果，意思是“竟然……、结果……”。如：

He studied hard only to fail in the exam.

他这么用功，竟然在考场上失利。

He rushed all the way to the station only to miss the train.

他一路冲往车站，结果还是错过了火车。

But表示转折。不过在其他情况下But for可以连在一起表示虚拟语气

含but for的句子一般用虚拟语气。但介词短语本身常常并不表示条件，而是隐含了条件。

But for my brother's help，I would not have finished the work．如果不是我兄弟帮忙，我就不会完成这项工作。

3.It's hard for them to learn new languages and be connected to the bigger world.

It is+adj.+of sb. +to do sth中的adj.跟sb.有关,
这个adj.是用来形容sb.的,
表示某人这么做真是太adj.了．
你会发现在这个句型中你把sb.和adj.提出来可以造个句sb. is(are) adj.
如It‘s very kind of you to help me.
把里面的sb.和adj.提出来可以发现you are kind是说得通的.

而It is +adj.+for sb.+to do sth表示做某事对某人来说很adj.
这里的adj.是do sth.的属性
里面的sb.跟adj.没有直接联系
