You should just be yourself. 你应该做你自己。5. surprise sb 使某人惊讶我敲了敲门，不想吓着她。 I knocked at door, I didn’t want to surprise her.6. so…that…和so thatso…that…如此…以至于…， so that以便于 例如：我是如此的害怕以至于我说不出话来。I was so afraid that I couldn’t say a word.你可以跟你的朋友谈谈以便于他不再生你的气。You could talk to your friend so that he isn’t angry with you.4a是一个控制性的语法练习，选词填空。由于连接词不涉及语言结构和形式上的变化，所以通过对这几个词的讲解，来训练学生对连接词表意功能的理解和运用。这是一个半开放性的练习，训练学生能够根据不同人物所面临的问题提出建议，写出完整的表达建议的句子。学生写的过程也是整理思路，用英语思考的过程，同时对加强语言表达的准确性也有帮助。4c是一个开放性较强的口语交际活动，通过游戏的方式灵活运用所学语言自编对话，为他人提出合理建议。Step4 Practice1. A student in Fudan University was killed by his roommate just because of small things in daily life. It is important for students to learn how to _____ each other. A. get on with B. come over to C. stay away from 2.It is wrong for us ______our parents.A. to argue with B. argue with C. to argue3.The little boy ______ his seat to an old lady on the crowded bus.
