could和should的区别:
1. should可以用于第一人称或第三人称的疑问句中,表示征求意见。
例如: My brother likes to listen to CDs. He often plays his CDs too loud. What should I do?
2. should 表示义务,可以用于提供建议,表示“应该”, 后面跟动词原形。
例如: Maria argued with her mother last night. She is very upset now. What should she do? I think she should say sorry to her mother.
3. should也用于表示某事发生的可能性,用于表示推测的词,意为“可能”。
例如: They should arrive soon.
4. could不仅仅是充当can的过去式,而且是一个单独的情态动词,表示“能;可以”,用来提供建议,后面跟动词原形,它和should在意义上不同,前者是“可以”,后者是“应该”,表示不同的态度,但两个都可以用来提供建议。
例如: You could borrow a bike to that park. I think you should have a talk with your friend.
