1、the problem is too hard to work out.
the problem is so hard that we cant work it out.
我想这一题只有这两个方法比较好，要考察的也只是这两个句型了。too...to / so...that 其它的翻译方法倒有不少，不过都没用到什么句型，所以不算经典。
2、i am glad/pleased to have you as my friend.
i am glad/pleased to such a friend like you.
it is my pleasure to have you as my friend.
这个句子抱歉啦，实在不知道要考察什么的。呵呵~~不过这也翻也不错啦，多换一些相近的词都算是新的句子。
