单选题 Last year he learned______he had expected because he worked a lot harder.

A、 twice as much as
B、 twice as many as
C、 twice more than
D、 twice as more as

【正确答案】 A

【答案解析】解析：句意：去年学到的东西是预期的两倍，因为他付出了更多的努力。固定用法题。英语中常用的倍数表达法为“倍数+as+形容词或副词的原级+as+其他” “倍数+形容词或副词的比较级+than+其他”或者“倍数+the size／length／height…of +其他”；又因“学到的东西”是不可数的，所以应用much。故选A。
