23/50单选题(2分) It's the best that you____.( )
A. will carry out the plan
B. would carry out the plan
C. should carry out the plan
D. carried out the plan
题目解答
答案
C. should carry out the plan
解析
本题考查虚拟语气在固定句型"It is the best that..."中的用法。核心思路是识别该句型后接从句时,必须使用"should + 动词原形"的结构,表示建议或期望。解题关键在于排除不符合虚拟语气形式的选项。
选项分析
A. will carry out the plan
错误原因:句型"It is the best that..."要求从句使用虚拟语气,而"will"是陈述语气,不符合语法要求。
B. would carry out the plan
错误原因:"would"表示过去将来时,通常用于间接引语或委婉语气,但此处需要"should"构成虚拟语气。
C. should carry out the plan
正确原因:"should + 动词原形"是"It is the best that..."结构的固定搭配,表示建议或最佳做法。
D. carried out the plan
错误原因:过去式"carried out"表示已完成的动作,与句型要求的虚拟语气(表示建议)矛盾。
