I have a stomachache .You( ) eat bad food A ,should B,couldn't C,shouldn't D,could
选D行不行啊,could 表可能,你可能吃了坏东西

【答案】C 选D 不可以
【句意】我肚子疼.你不应该吃坏了的食物.
1.could+have+done”是虚拟语气,表示对过去事情的假设,意思是本来能够做某事而没有做.
2.另外表示对过去的推测
△肯定句用：must / may / might +have + 过去分词
例：John might have read the book.
△否定句、疑问句用：can / can’t / could / couldn’t + have + 过去分词
例：The ground isn’t wet.It can’t have rained last night.
