问题补充：

— Joan has never been to Beijing. What about Jack?

—

A. So has he.

B. Neither he has.

C. So he has.

D. Neither has he.

答案：

A. So has he.

B. Neither he has.

C. So he has.

(答案→)D. Neither has he.

解析：根据所学可知，“so＋助动词（情态动词或连系动词）＋另一主语”，表示前面的情况也适用于后者。So+主语+助动词（情态动词或连系动词）是对上文所说的情况加以肯定。如果上文是否定形式则要将so换成neither。句意：乔从来没有去过北京。杰克呢？结合语境可知下文表示前面情况也适用于杰克，且为否定语气。故选D。
