Unit2 A 扩展阅读should与could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,它与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.第 2 页
