Canonical analysis

A year is divided into_______months.August is the_______month of the year.

A.twelve;eight

B.twelve;eighth

C.twelfth;eight

D.twelfth;eighth

【解析】句意:一年被分成12个月,八月是一年中第八个月。

根据句意“一年被分成12个月,八月是一年中第八个月。”,第一个设空处后面是复数名词,需要用基数词twelve强调数量;第二个设空处根据前面的定冠词the和后面的名词单数形式,判断需要用序数词作定语,表示“第几个”,eight的序数词是eighth,故选B。
