－You _______ be happy with the strong public support you’ve received.－Yes,you’re right.I’m really excited.

—I’m afraid you missed a fantastic lecture yesterday. How come you were absent from it?—If you _______ know, I asked for a day off and visited a relative of mine in hospital.

—Please don’t tell anybody．—I     . I promise．
