网友回答
(答案→)in改为on
解析：
【小题1】in改为on 具体到某一天使用介词on。
【小题2】good改为well 固定搭配do well in…在某方面表现良好。
【小题3】and后面加was and表示并列结构，be fond of…喜欢；本句使用一般过去时的时态。
【小题4】去掉into 动词enter是一个及物动词，后面直接加宾语，不需要介词。
【小题5】year改为years 前面有four修饰，说明这里使用复数形式。
【小题6】get改为got 本句叙述的是已经发生的事情，故使用一般过去时的形式。
【小题7】去掉in this year在句中单独做时间状语，不需要属于in this year。
【小题8】but改为and 上下文是并列的关系，故使用and连接。
【小题9】gratefully改为grateful 本句中的形容词grateful与be连用，形成系表结构。
【小题10】receive改为receiving 本句的to是介词，后面要接动名词的形式。
