Question

LiYang, a famous English expert, will deliver a speech telling us a good way to have our oral English______in a short period.

  A. to improve    B. improving     C. improved    D to be improved

Answer 1

C

解析:

本题考查have sth done结构。因oral English与动词improve之间为被动关系，故选C项。注意D项尽管表示被动，但没有have sth to be done结构。
