总论点

Dental amalgam用来做dental repairs很多年，是mercury跟其他金属一起用的mercury有巨大危害，要prohibit, 阅读材料exaggerate mercury的危害

阅读部分

1.Health problems: 即使很小量的mercury进入人体也会有adverse effects

2.Contamination: waterways and wildlife会受到摧残，mercury沉在河底

3.Alternatives available: 专家说像gold啊什么的一些材料可以替代mercury用在dental repairs

听力部分

阅读材料exaggerate mercury的危害

1.small amounts of mercury被人体吸收了根本没什么harm，那些导致bad health的是因为allergic to mercury，而且这个概率非常小

2.有一种东西叫separator，可以做filter，在water passes的时候把solid material给collect起来

3.Mercury是最好用的，人嘴里是constant wet environment，mercury can be longer used。其他替代物像gold，per unit都很贵啦

解题思路

1. 阐述阅读与听力材料总论点之间的关系

2. 阐述阅读与听力材料的三个分论点之间的关系，着重描述听力部分的观点细节

参考范文

Dental amalgam has been suggested to be dangerous in view of the author while the professor refutes that the danger of mercury has been exaggerated in the reading.

First, the professor argues against the point in the reading passage that small amounts of mercury can cause adverse effects when entering into human body, pointing out that small amounts of mercury absorbed by human body has little harm. Bad health is only caused by being allergic to mercury, which happens in a low percentage.

Second, it is said in the reading passage that waterways and wildlife can be terribly affected and contamination will be caused by the use of mercury. However, the professor maintains that there is a separator which can be used as a filter to collect solid materials when water passes.

Last but not least, on contrary to the points that there can be many other alternatives like gold which is available for being used in dental repairs, the professor argues that mercury has more advantages over any other materials for dental repairs. Since human mouth keeps a constant wet environment, mercury can be longer used. Also other materials, taking gold as an example, is quite expensive per unit.

考题回忆

In many places, students have to arrive school very early in the morning. Some people think school should support learning, other think it not a good idea. Do you agree or disagree?

解题思路

Disagree:

早上如果太早，肯定会有lack of sleep的问题，会影响效率跟产出efficiency and productivity；

每个人的作息习惯不一样，有些学生早上效率未必高，如果晚上效率高的话那完全可以focus on study at night，学校不应该强制早上学习

然而对于self-control跟self-motivation差的学生来说，学校要强制性要求早上学来do self-study

参考范文

The ever increasingly fierce competition among students nowadays makes it necessary for students to focus more time on study. School should play its supporting role in encouraging students to study hard so as to perform well in academic study but requiring students to arrive school very early in the morning seems not to be a beneficial way.

There is no doubt that early in the morning students tend to have a clear mind on condition that they maintain a good sleep last night. However, in view of an overwhelming amount of assignment to do and examinations to prepare, students can hardly maintain sufficient sleep at night. In this case, lack of sleep dramatically lower the study efficiency and productivity. Suffering too much pressure, students may not be able to concentrate on study especially very early in the morning. For instance, when my cousin was in senior high school preparing for College Entrance Examination, their school required all the students to arrive school before 6 o’clock every morning, which means students has to get up around 5 o’ clock so as to be on time. He has complained very often because he studied until midnight only to finish all the assignment and reviews that he could scarcely sleep very well, thus resulting in bad condition of study and what is worse is that getting up too early leads to incapability of focusing and listening carefully in class. Such irrational schedule can only make negative consequences.

More importantly, every student must keep an exclusive study habit especially in time arrangement. Researches carried out by educational institutions show that study efficiency depends on some factors that are easily ignored such as different period of time in a day. Some students prefer to study in the morning because they think during that time it seems more probable to keep a clear mind. On the contrary, some other students would rather concentrate on study at night on the grounds that during that period of time there are less distractions and disturbance. Take me as an example, the most favorable period of time for study is undoubtedly late at night. Without any distractions like peers’ talking to each other, I can be more productively doing my study and reviews. Provided that school forces me to follow the official schedule, that is, showing up at school every early, I am convinced that I will be driven crazy, not to mention how adverse it will exert on my study.

Admittedly, there are some special cases in which school should be responsible to monitor students in their time arrangement of study. Students who lack self-control and self-motivation, to a large extent, should be required to arrive school very early to do self-study, in the hope that they can make full use of available time.

In conclusion, school, served as a significant role in education, should support learning but in some other effective ways rather than requiring students to arrive school too early for study.
