2022年高考英语人教版第二轮复习知识点精讲11并列句和状语从句(五).docx

四、目的状语从句 目的状语从句是表示行为目的的从句。引导目的状语从句的主要连词有that, so，so that, sothat, in order that等，从句中常常使用一些情态动词，如can, could, may, might, should等。（一）that, so that，in order that表示为了，以便，一般放在主句之后。that语气较弱，用的较少，多用so that。 Let's take the front seats that we may se more clearly.我们坐前排吧，这样我们可以看得更清楚些。 Man does not live that he may eat, but eats that he may live.人生存不是为了吃饭，而吃饭是为了生存。 They hurried so that they might not miss the train.他们为了不误火车，才急急忙忙的。 In order that everyone might hear her clearly, she raised her voice again. 为了使每个人都听清楚，她再次提高了声音。 注意：当主从句的主语一致时，so that和in order that引导的目的状语从句可以转换成相对应的动词不定式结构。 We got up early so that we would arrive in time.为了能及时赶到，我们起得很早。 They hurried so that they might not miss the train. They hurried so as not to miss the train. 他们为了不误火车，才急急忙忙的。 Betty saved money in order that she could buy a computer.
