作者:邱世才 这一单元学过的每句话几乎都离不开should和could, 你们肯定对它们两个产生了很大的兴趣吧。那么你们首先要清楚一点,should和could属于两个情态动词。 情态动词,简单地说,它表示的是说话人对动作的观点,既需要、可能、意愿或怀疑等。 一、情态动词should 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:1) My brother likes to listen to CDs. He often plays his CDs too loud. What should I do? 2) Dennis wants to take part in the summer camp. But he doesnt have enough money. What should he 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. 二、情态动词could 本单元所学习的could不仅仅是充当can的过去式,而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:—I will take part in a party tomorrow night. But my clothes are out of style. I need some money to buy some clothes in style. What should I do? —You could borrow some money from your friends. —No, I dont like to do that. —Then you should get a part-time job and make some money. 相关链接:教学论文
