3. 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：A。
解析：have sth. done 表示“使某事被做”，have her written English improved “使她的书面英语得到提高”。动词+ed 形式作宾语补足语表示被动。have sb. doing sth. 意为“使某人一直在做某事”表主动。have sb. do sth. 意为“使某人做某事”表主动，do 前必须省略 to。所以选 A。
