认真阅读下面一段访谈记录，回答后面的问题。
王：咱们学校四位教师，四个年级，个个都是班主任吗
贾：个个都是班主任。包括校长在内。(笑)
王：你是哪个年级的班主任
贾：我负责一年级。语文、图画、国情等，除数学外，都由我教。四年级数学也由我带。音乐课一周一次，由女教师(马占梅教师)给全校的学生教唱歌。别的老师音乐知识没有，带不来。
王：您的学生对您的评价很高，您能不能给我们介绍一下您是怎么备课的。
贾：现在方便一些，因为有现成的教案。上课前看一看课上面临的主要问题。
王：你是说特级教案
贾：对，特级教案。看看上面的要求、做法和学生的实际情况结合起来。那是特级教案，而我们的学生见的少，完全按特级教案，学生接受不了。当然，我们做教师的也不一定完全了解特级教案。(笑)
王：有没有别的备课用书
贾：基本上没有。
王：有没有教学大纲
贾：教学大纲有哩。
王：人教社出版的那套教学参考书，有吗
贾：没有。
王：你平时上课时所采用的方法和今天所采用的方法都一样吗
贾：都一样，平时就这么上，你们来听课，我也没做什么准备。
王：你为什么那么上课，依据是什么
贾：我是根据教学内容，看学生的情况，和大夫很像，大夫是根据病情，打针吃药，把病治好，老师想把自己的知识全面、系统地教给学生，所以，想些办法根据学生的接受能力给他们讲。老师在课上讲的多一些。

听下面一段对话，回答下列问题。
Members of the city council and distinguished guests, it is my privilege to introduce to you today Mr Robert Washington, chief of our city’s police force. He will address us on the subject of the Community Policing Program. Most of you know that Mr Washington has a distinguished record as head of our police force for more than ten years. However, you may not know that he also holds a master’s degree in criminology and studied abroad for a year with the international police force which deals with crimes around the world. Mr Washington first introduced the Community Policing Program 8 years ago. The idea behind the program is to get the police officers out of their cars and into our neighborhoods where they can talk directly to merchants and residents about the real dynamics of our city. These officers do more than make arrests. They try to find ways to help solve the problems that contribute to crime in the first place. Often that means hooking
A. To introduce the beautiful view of the city.
B. To give some comments on another person’s talk.
C. To address the matter of community security.
