问题补充：
I’m going to the supermarket this afternoon. Do you have anything?
A. bought
B. to be bought
C. for buying
D. to buy
答案：
A. bought
(答案→)B. to be bought
C. for buying
D. to buy
解析：考查非谓语动词的用法。这里要注意have意思的理解。have为“有”，主语是you 他不参与buy的动作；不要和have sth done 结构混淆，此处的have 为让别人作，被动。
(1). I have something to tell you.(此处的have 为有，但主语参与用to do ;)
(2). I have my hair cut.(此处的have 为使，让德意思，主语不参与让别人做，事不能发出后面的动作为被动)
（3）I have you do that again.(此处sb.能发出动作。)
