She pretended _____(not see) me when _____(shop) down-town.down-town
key：not to have seen；shopping
为什么用not to have seen？？？

请把理由讲的详细一点噢 谢谢

只接不定式作宾语的词和词组有：decide,expect,refuse,wish,hope,order,promise,pretend,offer,happen,seem,make up one's mind,used,be about,be able,have等。
也就是说pretend to 是固定用法
如：（89高考）She pretended_______me when I passed by. A.not to see B.not seeing C.to not see D.having not seen
