Be Greek to me

一点也不明白
Greek解作“希腊语”，很多人相信希腊语是很难学习的。It's all Greek to me.直译就是“这些对我来说尽是希腊语”，用来比喻“我一点也不明白这些话或事”。
1.Dr. Qian is a very famous scientist but literature is all Greek to him.
钱博士是位著名的科学家，但对文学却一窍不通。
2.Mr. Li has tried to explain the lesson to us twice already but it is still Greek to us.
李老师已把那课书讲解了两遍，但我们仍一点也不明白。
I can't make head or tail of it 和It is all Greek to me，有异曲同工之妙，都解作“我一点也不明白”。
