网友回答
(答案→)there was 改为there were
解析：上周日下午，我和莉莉去动物园。动物园里有很多人，我看到一个小女孩在哭，原来她迷路了，找不到妈妈了。于是我们决定帮助她找到她妈妈。我和莉莉分头行动，我去找到动物园的广播处广播，而莉莉则陪小女孩一起玩。在我们的帮助下，小女孩回到了妈妈身边。
【小题1】考查主谓一致。There was lots of people there。 There be 句型中be动词在人称、数上要和后面的名词保持一致，所以把was 改为were。
【小题2】考查非谓语动词。I found a girl cry in the zoo cry 。find sb doing sth，其中宾语和 宾补是主动关系，故用现在分词，所以把cry改为 crying。
【小题3】考查动词时态。She was lost and she can’t find her mother根据语境可知此处是表示过去，所以把 can’t 改为couldn’t。
【小题4】考查动词时态。I try my best find the broadcasting station。根据文章时态判断此处是过去时，所以把 try 改为 tried。
【小题5】考查非谓语动词。I try my best find the broadcasting station。固定短语“try one’s best to do ”意思是“努力做某事”，所以在find前加to。
【小题6】考查固定短语。On the same time Lily played with her。固定短语 at the same time“同时”，所以把on 改为at 。
【小题7】考查副词用法。Lily played with her and looked after her careful there。修饰动词短语look after 应该用副词，所以把careful 改为carefully。
【小题8】考查代词用法。At last his mother came.根据上文可知此处是指小女孩的妈妈，所以把his 改为her 。
【小题9】考查形容词用法。That made me feel very happily. Feel 是系动词后面跟形容词做表语，所以把happily改为 happy 。
【小题10】考查动词用法。If everyone helps with each other。help是及物动词，后面直接跟宾语，不需要介词，所以把介词with去掉。
