Question

【題目】 If you ________ the medicine yesterday, you ________ well now.

A. took, might be B. had taken, might have been

C. had taken, might be D. took, might have been

Answer 1

【答案】C

【解析】

試題分析：考查虛擬語氣。本句條件句中時間狀語是yesterday，這是一個過去時間，所以從句中使用“過去完成時”表示與過去相反，主句的時間狀語是now，說明主句與現(xiàn)在事實(shí)相反，所以主句使用“情態(tài)動詞+動詞原形”。句意：如果昨天你服藥了，現(xiàn)在你就會很好。故C正確。
