{01}Our class discussed the question of __________it is necessary for us students to use mobile phones on campus.
A.if
B.where
C.whether
D.that
解析:本题考查宾语从句。句意:我们班上讨论了我们的学生在校园是否有必要使用手机的问题。 结合句意可知of后接宾语从句,有“是否”的含义,故用whether。介词后的从句不用if引导。 本题选C。 {02}Best-selling author and race car driver Han Han offered a 20 million RMB reward to _____ could prove his works were ghostwritten (代笔).
