A.因为函数内部不能修改变量的值，所以代码输出: [1, 2, 3]
B.因为函数内部不能修改变量的值，所以代码输出: 1, 2, 3
C.xList是可变对象，该函数修改了xList变量存储的值，所以代码输出：[2, 3, 4]
D.xList是可变对象，该函数修了了xList所指向列表的内容，所以代码输出：[2, 3, 4]

【简答题】Passage 1: Television changed my life forever. We stopped eating dinner at the dinning-room table after my mother found out about TV trays. We kept the TV trays behind the kitchen door and served ourselves from pots on the stove. Setting and clearing the dinning-room table used to be my job; setting and clearing meant unfolding and wiping our TV trays, then, when we’d finished, wiping and folding our TV trays. Dinner was served in time for one program and finished in time for another. During dinner we used to talk to one another. Now television talked to us. If you had something you absolutely had to say, you waited until the commercial, which is, I suspect, where I learned to speak in thirty-second bursts. As a future writer, it was good practice in editing my thoughts. As a little girl, it was lonely as hell. Once in a while, I’d pass our dinning-room table and stop, thinking I heard our ghosts sitting around talking to one another, saying stuff. Thesis: ________________________________________________________________________ Passage 2: People interrupt for various reasons. One is believing that what they have to say is more important than what the other person is saying. Another reason people interrupt is that they believe they know what the other person is going to say and want the person to know that they already know. People may also interrupt when they are not paying close attention. The interruption communicates a lack of sensitivity, a superior attitude, or both. People need to be able to verbalize their ideas and feelings fully; inappropriate interruptions are bound to damage their self-concepts or make them hostile – and possibly both. Simply stated, whatever you have to say is seldom so important that it requires you to interrupt a person. When you do interrupt, you should realize that you may be perceived as putting a person down. The more frequent the interruptions, the greater the potential harm.
