2. C
解析：根據(jù)“ever”可知用現(xiàn)在完成時，結構為have/has+過去分詞，see的過去分詞是seen，選C。

(4) I have cleaned the car. (就畫線部分提問)

cleaned
?
答案：(1) they have
解析：現(xiàn)在完成時一般疑問句的肯定回答為“Yes, 主語+have/has.”，主語是they，用have。
(2) hasn't turned
解析：現(xiàn)在完成時的否定句在have/has后加not，has not縮寫為hasn't，后面接過去分詞turned。
(3) Have you
解析：現(xiàn)在完成時的一般疑問句將have/has提到主語前，第一人稱I改為第二人稱you，already改為yet放句末。
(4) What; cleaned
解析：畫線部分“the car”是賓語，用what提問，現(xiàn)在完成時的特殊疑問句結構為“特殊疑問詞+have/has+主語+過去分詞?”，此處主語是you，用have，cleaned不變。
