It was at five o’ clock yesterday afternoon which I was going home by bus. The bus was full of passenger, all of who kept silent. A mother with her little son were sitting nearby. All of a sudden, the son cried loudly. The mother tried to do what she could make him stop crying. However, the son goes on crying. After what seemed a long time, a man seating next to the mother said angry, “ I can’t stand it anymore. Why don’t you give him what he wants?” The mother answered quietly, “I would if I could. But what she wants is your cap.” Hearing of this, all the passengers burst into laughter.which--that
网友回答
(答案→)which--that
解析：文章讲述了发生在公交车上的一件趣事，一个孩子哭个不停，惹得旁边一个男人生气了，结果发现婴儿是想要他的帽子，全车的乘客都不由得笑了。
【小题1】考查强调句型，it is/was...that是强调句型，强调除谓语外的成分，这里强调的是时间状语，强调句型去掉后不影响句意。故把which改为that。
【小题2】公交车里挤满了乘客，根据句意可知，有不止一个乘客，故把passenger改为passengers。
【小题3】考查定语从句。介词后用which或whom，关系代词who一般作主语，不能放在介词后，这里指人，故把who改为whom。
【小题4】考查主谓一致。with连接名词作主语时，遵循“就远原则”，谓语与with前面的保持一致，故把were改为was。
【小题5】考查不定式表目的。那个妈妈尽她所能来使婴儿停止哭泣，这里用不定式表目的，what she could是宾语从句，故在could后加to。
【小题6】根据第一句可知，是复数在昨天的事情，应该用一般过去时。故把goes改为went。
【小题7】seated坐着的，表状态，相当于sitting，故把seating改为seated。
【小题8】修饰动词said用副词，故把angry改为angrily。
【小题9】根据Why don’t you give him what he wants?可知，是一个男孩，故把she改为he。
【小题10】hear听到，是及物动词，hear of是“听说”的意思，听到这，所有的乘客都笑了。故去掉of。
