()She doesn't know__this afternoon.
A.what she can do it B.what to do it C.what to do D.what she does
答
正确：C （该句中：what to do =what she will/can do ）
答
C
A选项和B选项都是画蛇添足 只有how 才和 do it 搭配 what 只和do搭配
D选项要表达的是已经做过的事 要用过去时 但是又和语境不符 纯属干扰选项
答
选C.
她不知道今天下午做什么.
A,B,what和 it 重复,去掉 it才对；
D,时态不对,主句用一般现在时,从句时间状语是今天下午this afternoon,从句应该用一般将来时.
答
C
她不知道今天下午做什么
注：A中的WHAT 应该是HOW ； B 中多了IT或把WHAT 改为HOW ； D 的意思‘ 她是做什么的’
