Millie is very tall and sits me. So I can’t see the blackboard.

A. behind

B. in front of

C. beside

D. under

答案：

A. behind

(答案→)B. in front of

C. beside

D. under

解析：句意:Millie很高，而且坐在我的前面，所以我看不到黑板。behind 在...后面；in front of 在...前面；beside 在...旁边；under 在...下面。根据句意可知，我看不到黑板，可见Millie应该是坐在我的前面。故选B。
