A new laptop costs about _____ of a second-hand one.
A three times the price B three times more than the price C three times as much as the price
老师好!这里的A是对的,B为什么不对?C是我自己写的,对吗?
A new laptop costs about three times the price of a second-hand one.
填入A项,倍数词three times为前位限定词,the为中位限定词,price为名词词组的中心词,后接 of a second-hand one作定语。整个名词词组作cost的宾语。
A new laptop costs about three times more than the price of a second-hand one.
填入B项,则more为代词作cost的宾语,than引导比较分句修饰more,比较分句省略了谓语动词costs. 你会发现,省略的谓语动词costs的主语成了the price. 这就成了逻辑错误。所以,如果用比较结构,than从句的主语就应该是a second-hand one. 而不是the price of a second hand one.
A new laptop costs about three times more than a second-hand one (does).
这就是B项错误的原因。你自己加的C项的错误同此。
