— My computer _______ start, no matter how hard I try.— It might have crashed.

—How did you find the film The Flowers of War?—It's very moving. I couldn't ________ my tears.

 My interest in surfing on the Internet has_______ most of my spare time, but it has repaid me a great deal of enjoyment.

—Xiaoming, you are late again, can you tell me why?—I was on the half way when it _______to me that I had left my notebook at home, so I have to fetch it.
