问题 There ______ more than 200,000 overseas domestic servants working in Britain.
选项 A、is estimated to be
B、are estimated being
C、are estimated to be
D、is estimated being
答案 C
解析 There be句型题。There be句型可以和动词的被动语态一起使用，常用结构有：There is／are expected to be．．．(预计……)；There is／are known to be．．．(据人们所知……)；There is／are estimated to be．．．(据估计……)。本题的真实主语为200,000 overseas domestic servants，为复数形式，故C正确。
