Jenny hopes that Mr.Smith will suggest a good way to have her written English in a short period.

A. improved

B. improving

C. to improve

D. improve

答案：

(答案→)A. improved

B. improving

C. to improve

D. improve

解析：have sth. done表示“使某事被做”，动词+ed形式作宾语补足语表示被动。根据written English与improve的关系可判断出要用动词-ed形式作宾语补足语，表示使她的英语书面语得到改善。动词-ing形式作宾语补足语表示主动，即表示宾语所做的事。不加to的动词不定式作宾语补足语(have sb. do sth.)，表示让、叫某人做某事。have后一般不用带to的不定式作宾语补足语。
