Task 4

　　阅读解释概念：internal attribute: 将事物发生的原因归结自己的内在问题，而不是外界因素。

　　听力教授举自己的例子解释这个概念。具体为：该教授青少年时期在一家公司工作，负责整理文件。他遇到困难总是不能及时完成工作。该教授没有抱怨老板也没有抱怨工作太多而是想办法提高自己的能力。最后教授提高自己的能力，能按时完成工作，变得非常擅长自己的工作。

　　解题要点

　　Term：internal attribute

　　Definition：Attribute causes concerning why things happen to internal factors other than external factors.

　　Lecture：

　　The professor gives an example of his own. When he was a teenager, he works at a firm where he had to collate documents. He usually failed to finish his job in time because of several difficulties. But he didn’t complain his boss nor did he complain the large amount of the work. In turn, he always came up with ways to advance his ability. As a result, the professor has improved his ability to complete his task in time and he turned out to be very good at it.

　　Task 5

　　听力男学生遇到的问题是时间冲突。一方面他要去机场接朋友，另一方面他想去参加一位作者的演讲。

　　两个解决方案为：

　　1 告诉朋友自己会迟到(提到的好处有：老朋友可以理解他迟到，这个朋友还可以自己在机场逛逛，吃点东西读书。缺点是朋友大老远跑来看他，不好意思迟到。2 不去参加的演讲。(提到非常想去，如果错过不会有第二次机会)

　　解题要点

　　Problem: The boy has to pick his friend up at the airport, but he also wants to attend a speech made by an author.

　　Solution 1: Tell his friend that he will be late.

　　Pro：His old friend will understand his being late, and his friend can also go around at the airport. He can read and eat whenever he wants.

　　Con：It is not polite to be late, especially when his friend has to travel so far to be here.

　　Solution 2: Cancel the plan to attend the speech.

　　Con：There won’t be a second chance for him to attend this author’s speech.

　　Task 6

　　生物课堂上老师讲解了有些树能够活很长时间的原因—树的适应性。主要有两个方面。

　　1 通过释放化学物质避免虫害。举例为red wood，树叶和树干中含有单宁酸，所以虫子不能忍受这种物质，所以不会去吃red wood.

　　2 发达的根系可以帮助在风暴中幸存下来。举例仍为red wood. 说首先有发达的根系stretch every direction, 以及还可以与周围的树木的根系相组合。互相缠绕在暴风中就不会有问题。

　　背景知识

　　In the biology class, the professor tells us that strong adaptability is the reason why trees can live long. S/he then explains it as the following two ways.

　　Main Idea:

　　Way 1: Avoid damage by insects by releasing chemical substance.

　　Example 1: Red wood has tannic/gallotannic acid in its leaves and branches, which the insects cannot suffer to eat and live with. So they will not eat red wood.

　　Way 2: Survive in storms through developed root system.

　　Example 2: Red wood has a developed root system that can stretch every direction and group with other trees’ roots. So if there is any storm, it can successfully survive by binding with each other.
