选择题
John passed the examination though he had only spent _______ on the subject as others had done.
A．as half time much
B．as half much time
C．half as time much
D．half as much time
答案
答案：D
考查倍数问题。as...as 结构，此句型意为“…和…一样…”。中间可加形容词、副词、可数不可数名词，本题中time是不可数名词，结构为as much／little＋<不可数名词>＋as，因此half不能出现在as...as中间
