高中英语代词选择题
I wonder __ my brother is to get to Shanghai.
A.it is when thatB.when is it thatC.that when it isD.when it is that
为什么选C

完整句子应该是这样:I wonder that when it is (that) my brother is to get to Shanghai.这样一层一层来吧,首先是I wonder that when it is.先行词that充当宾语,相当于代词,宾语内容是when.由于这是一个宾语从句,所以when后面用了陈述语气.而“it”在宾语从句中充当形式主语,代替了My brother is to get to Shanghai.
