补充一点听力机经 不一定准确哦,大家看着修改修改.睡了一觉起来，忘了一大半，惭愧) １．on campus dialogue one: 一个男生到他的女教授办公室谈论教授布置的作业问题.教授让男生在学校取景制作一个film, the man asks the professor several questions. (1)为什么不可以在学校外面取景,他认为学校外面有一块地方景色很好.教授回答,这样要求学生是为了让学生知道如何利用有限的资源（好象也有题）(2)film的时间有限制，只有１２分钟，学生问为什么不可以拍长一点时间．教授说是为了让学生明白如何direct and choose the crucial part of the film because the first learner always contain too many thing that are needless.(有题）然后教授说，世界有名的导演拍片的时候都要注意适应紧急情况，并且有效地利用他们的资源（比如资金，演员．．．．）最后，男生同意了教授的观点，认为教授做这样的限制有好处（有题） dialogue 2: 一个男的到图书管理员那里说他无法上网登陆他的ID 号码，管理员说你是不是有不好的记录或者有书没有按时还（有题，问为啥这样说，我选的是提供一个可能的解释），then the man anxiously said that no, I have returned 2/3 books yesterday. Then the librarian check the man's records and found the problem. Because he had a book that is overdued (entitled animal...)and this overdued book is checked out/required by another student. That's the problem. The man feel confused and didn't know why it happen. The librarian told him that if his book is overdued and this book is required by others, he cannot have that one. The man felt unhappy because he used that book to prepare for his presentation/paper. He has found that this book helps a lot and is what he needs most. (forgot)(有题，问从男生的回答中可以看出什么，it shows that the man concerns to get information from the book). Then the librarian told him that it's the rule. He could take notes from the book before returning it or just bought another man. At last, the man agreed to do so. 'well, i may come to find another book....'(有题，问这暗示了什么，i choose'the man means that he will give the book back' ２．学术段子 一个是讲chemical reaction between bacterias. At the beginning of the lecture, the professor told the students that animals, plants can use chemical reactions to communicate with each other, not like the way we human do. Then the professor said even bacteria, the primitive form of life, can even do so. 然后教授说开始有一个女的在听讲座的时候听到一个同行说细菌可以'talk', 然后那个女的就心想，＇get out, the bacteria obviously cannot talk'. 但是那个女的还是对此很有兴趣，于是动手研究．结果发现细菌真的相互交流，只是用chemical communication.后面有一点忘了，有一个专业术语，．．．sensing,然后举了一个例子，说在某大洋上，有一种algae, 在船行驶过洋面的时候，会发出一种淡淡的光并发出一种信号，其它的感受到以后也竞相发光，这样在洋面上形成了一道闪烁的光带，like milky ..(forgot it) 最后，教授说这种sensing可以运用于其他领域，比如医生通过track the signals emitted by the bacteria, 可以抑制病毒或者细菌的生长或者控制其排放的毒素，then she said many big medicine/big companys 对个蛮感兴趣（有题，i think the answer is the big companys invest money or pay much attention to ..sensing） |
