问题补充：

---How much did the new watch your sister?

---She 350 yuan for it.

A. cost; paid

B. spend; cost

C. pay; cost

D. take; paid

答案：

(答案→)A. cost; paid

B. spend; cost

C. pay; cost

D. take; paid

解析： spend人作主语，宾语是时间和金钱，结构是人+spend+时间/金钱+on+名词，人+spend+时间/金钱+(in)V-ing;pay,付款人作主语，常用词组pay for;take 花费时间事物作主语，常用句式it+takes+sb+ ST+to do sth;cost,物作主语，只能花费金钱。这块新表花了你的妹妹多少钱?她为这块表付了350元。故选A。
