As ________ announced in today’s papers, the Shanghai Export Commodities Fair is also open on Sundays.

A) being B) is

C) to be D) been

Which one would you think is the best choice to complete the sentence?

My choice is A. How do you think about it?
I wouldn't choose A. Emotion: smile
Given the choice, I would leave the blank blank. If I have to choose one, it would be B. Infinitive form (to be) usually follows a conjugated verb, and the others are the wrong tense.
Students: Are you brave enough to let our tutors analyse your pronunciation?
I didn't want to give a solution, but I do agree with you, Vorpar. Either nothing, or "is".
