Question

I’m surprised to hear from my school teacher again. ______, it is ten years since we met last.

1. A.
   In a word
2. B.
   Believe it or not
3. C.
   That’s to say
4. D.
   Of course

Answer 1

B
短语辨析。In a word总之，一句话；Believe it or not信不信由你；That’s to say那就是说；Of course当然。句意：我非常吃惊又收到我的老师的来信。信不信由你，自从我们上次见面已经十年了。所以选B。
