单选题 Who________America？A.foundB.discoveredC.inventedD.found out

B解析分析：invent(发明)指世界上还没有的东西被做出来了，如：invent the telephone；discover(发现)是指比别人“先发现”，如：It was Columbus who discovered America．；find out(发现)是指“弄清楚”“搞明白”一件事情的真相，因此这种“发现”是指经过了研究或努力才得到的，常常跟宾语从句，如：In the end the people found out that their president had told a lie．；find(发现)指不经意间的发现，就是指并没有去努力，而偶然的发现，如：When I went to school yesterday morning，I found a wallet lying on the ground．(延伸)find(找到)和look for(寻找)相对应，look for是指“寻找”的过程，而find是指“寻找”的结果，如：What were you doing iust now？I was looking for my pen．Have you found it？Yes，I have found it．(延伸)find作“感到”解时，意思和think或feel作“觉得”的意思差不多，如：I found this story very interesting．＝I found that this story was very interesting．／Some people find it difficult to learn a foreign language．＝Some people find that it is difficult to learn a foreign language．
