单选题

It so happened that he________there were two uncorrected mistakes on his test paper.A.foundB.invitedC.inventedD.found out

网友答案:
A解析分析:句意是“他碰巧发现他的试卷上有两个没有改出来的错误。”,是指偶然性的发现,所以选A项。(延伸)原句=It so happened that he found two uncorrected mistakes on his test paper.=He happened to find there were two uncorrected mistakes on his test paper.=He happened to find two uncorrected mistakes on his test paper.(延伸)本题的“发现”,既是“偶然”的发现,也是别人尚未发现的,所以也可以用discovered(discover跟名词或从句)。
