选择题
--- Beijing has improved a lot these years. ---- _______ and ________.
A．So has it, so has Shanghai
B．So has it, so Shanghai has
C．So it has, so Shanghai has
D．So it has, so has Shanghai
答案
答案：D
题目分析：句意：这些年北京改善很多。是的，上海也是。And前句子是在对前一人的说话内容肯定，该用so的半倒装句即so + 主语 + 系动词be或助动词；and后句子是说前者的情况也适合后者，该用so的全倒装句即so +系动词be或助动词 + 主语。所以选D。
