网友回答
(答案→)before→after
解析：摩斯奶奶在她学绘画后不久就对画画痴迷起来。她画地非常仔细，而且作品也非常好。她开始绘画的时候只是为了自娱自乐，但是后来一位收藏家碰巧发现了她的作品，便立刻买下了她全部的作品。后来他为了介绍摩斯奶奶的作品而专门办了一次画展。
【小题1】考查连词。soon before she picked it up由上下文可知她是在学画画之后才会对绘画变得着迷上瘾，故把before改成after。
【小题2】考查副词。She painted carefu。修饰动词应该用副词，所以把careful改成carefully。
【小题3】考查不定代词。She first painted only to please oneself,。oneself要随着主语变化，所以把oneself改成herself。
【小题4】考查介词。and then began to sell her works with a little money，固定短语：sell sth for some money“某物卖了多少钱”，故把 with改成for。
【小题5】考查动词时态。Louis Caldor happen to see several of Grandma Moses’ work，文章背景是过去时态，所以把 happen改成happened，
【小题6】考查名词单复数。several of Grandma Moses’ work。由语境可知此处work表示作品，应该用复数形式，故把work改成works。
【小题7】考查谓语动词。He liked them, buying them at once, and set out to look for less 此处表示三个连续的动作，所以把buying 改成bought。
【小题8】考查不定代词set out to look for less。由语境可知此处表示“更多”的意思，故把less 改成more。
【小题9】考查固定短语。introduce the works of Grandma Moses other artists。introduce sth to sb“把……介绍给某人”，故在 Moses和other间，加介词to。
【小题10】考查谓语动词。who was world-famous, was died on December。die是不及物动词，不用被动形式，所以把die前面的was去掉。
