选择题
________ a lot of trees in this area, but now we can see a tall building instead.
A．There used to have
B．There used to be
C．There is used to having
D．There is used to being
答案
答案：B
考查there be结构。句意“这个地区过去有很多树木，但现在，取而代之的却是一栋大楼。”“过去有......”用there used to be表示。There be结构不能和have混用，排除A、C；be used to doing sth.“习惯于......”，排除D。故选B。
