Question

【題目】He _____ with English grammar every night over the last three months.

A. struggles B. struggled

C. has been struggling D. had been struggling

Answer 1

【答案】C

【解析】考查動(dòng)詞時(shí)態(tài)。句意：在過去的三個(gè)月里他每天晚上都在努力學(xué)英語(yǔ)語(yǔ)法。根據(jù)over the last three months可知強(qiáng)調(diào)在過去時(shí)間段，一直從事某件事，優(yōu)先選擇現(xiàn)在完成進(jìn)行時(shí)，即C項(xiàng)正確。
