Question

The teacher asked more ________ to prevent the students’ eyes from _______.

[　　]

A．to do; injuring

B．done; injuring

C．to be done; being injured

D．being done; being injured

Answer 1

答案：C
解析：

考查非谓语动词的被动式。ask sth. to be done是“要求某事被做”的意思，more与do的关系是被动的；prevent sb./sth. from being done阻止……被做；eye与injure的关系也是被动的。
