Currently, there is a widespread belief that modern society attaches more appreciation to teachers. From my perspective, however, teachers were more appreciated and valued in the past.

In the first place, the tradition in the past requires people to respect teachers. In the past, teachers were equal to parents, for they not only imparted knowledge but also cultivated children’s personality. Moreover, children had to live with the teachers in most cases, which, to some extent, provides more opportunities for teachers and students to communicate with each other. As children had a deeper understanding of their teachers, they would show more respect and appreciation. By contrast, students spend less time with their teachers and they may only gain knowledge from their teachers; thus, teachers exert a smaller influence on students and get less appreciation. For example, my grandfather still always talks about his teachers in his childhood and he tells me when his teachers were still alive, he and his classmates often visited them on holidays. My grandfather really shows a great respect to his teachers. However, I do not place too much value on my teachers and never visit them on holidays. Even some of my classmates always avoid meeting teachers in the street, let alone to say hello to the teachers. Compared to the modern society, the tradition in the past demands a greater respect and appreciation for teachers.

Furthermore, the teacher in the past was the only source of knowledge. In the past, there were few reference books and other resources. The only way to understand the obscure text and to learn the method to solve problems is to attend class and listen to the teacher carefully. At that time, teachers were the embodiment of knowledge. Therefore, it is easy to understand why people respected teachers in the past. In contrast, more reference books and materials are available in modern society, and students can even use the Internet to search the information they need. In such a sense, the importance of the role of teachers wanes. For instance, compared to my grandfather, who only relied on his teachers to gain knowledge, I acquire knowledge in a variety of means, including newspaper, magazines, television and the Internet. If one of my teachers does not teach well, I can take advantage of the Internet courses. Since modern students have access to more choices of source of knowledge, they may respect their teachers less.

In conclusion, teachers were more appreciated and valued by society in the past than they are nowadays due to the tradition in the past as well as their role as the only knowledge source.

托福tpo41写作范文 第2篇

In 1938 an archaeologist in Iraq acquired a set of clay jars that had been excavated two years earlier by villagers constructing a railroad line. The vessel was about 2,200 years old. Each clay jay contained a copper cylinder surrounding an iron rod. The archaeologist proposed that vessel were ancient electric batteries and even demonstrated that they can produce a small electric current when filled with some liquids. However, it is not likely that the vessels were actually used as electric batteries in ancient times.

First of all, if the vessels were used as batteries, they would probably have been attached to some electricity conductors such as metal wires. But there is no evidence that any metal wires were located near the vessels. All that has been excavated are the vessels themselves.

Second, the copper cylinders inside the jars look exactly like copper cylinders discovered in the ruins of Seleucia, an ancient city located nearby. We know that the copper cylinders from Seleucia were used for holding scrolls of sacred texts, not for generating electricity. Since the cylinders found with the jars have the same shape, it is very likely they were used for holding scrolls as well. That no scrolls were found inside the jars can be explained by the fact that the scrolls simply disintegrated over the centuries.

Finally, what could ancient people have done with the electricity that the vessels were supposed to have generated? They had no devices that replied on electricity. As batteries, the vessels would have been completely useless to them.

Your reading says that these vessels were not used as batteries in ancient times, but the arguments used in the reading are not convincing. The battery explanation could very well be correct.

First, about the absence of wires or other conductors, Remember, vessels were discovered by local people, not archaeologists. These people might have found other material located near the jars. But since they were not trained archaeologists, they may not have recognized the importance of that material. So materials serving as wires or conductors might have been overlooked as uninteresting or even thrown away. We’ll never know.

Second, it is true that the copper cylinders in the vessels are similar to cylinders used to hold scrolls, but that does not really prove anything. It’s possible that the copper cylinders were originally designed to preserve scrolls. And that some ancient inventor later discovered that if you use them together with iron rods and some liquid in a clay vessel, they will produce electricity. That’s how the first ancient battery could have been born. In other words, the copper cylinders could have been originally used for one purpose, but then adapted for another purpose.

Finally, there’s the question of the possible uses of the battery in the ancient world. Well, the battery could produce a mild shock or tingling sensation when someone touched it. This could very well have been interpreted as evidence of some invisible power. You can easily see how people could convince others that they had magical powers through the use of the battery. Also, the battery could have been used for healing. Modern medicine uses mild electric current to stimulate muscles and relieve aches and pains. Ancient doctors may have used the batteries for the same purpose.

The coal ash pollutes the environment a lot and some people claim that new regulations are necessary to reduce pollution. The passage are talking about three undesirable consequences of new regulations. However, the speaker holds that the new strict regulation is definitely needed to handle the coal ash.

Firstly, according to reading, there are some regulations already. However, the lecturer points out that the regulations now are not sufficient. This is because under current regulation, the company only use liner when they build a new landfill or pond. But the chemical material in the old sites damaged the ground water even contaminate the drinking water. Therefore, a new strict regulation is absolutely necessary to prevent the damage both in old and new sites.

Second, the reading material suggests that the regulation may invoke people's concerns on recycling coal ash. On the contrary, the professor maintains that the regulations doesn’t mean that people will stop use recycling coal ash. She argues that we can observe people's response to other dangerous thing such as the mercury. The mercury is a dangerous metal and subject to regulation and it have been recycled for fifty years, but few people concern about its security. So we should not afraid of the concern of people.

Thirdly, the author mentions that the new regulations will add financial burden for power company. The speaker maintains that although it is true that new regulation will increase costs, but it is worthwhile. Through analysis, the implement of new regulation will cost fifteen billion for power company. However, the improvement only a percent of the price of environment. He thinks the clean environment are much worth than this money.

整体来说是一篇发挥不错的综合写作，阅读概括能力强，听力部分只有第三个分论点细节缺少，“，increase 1 % of the electricity bill per household”。很多同学对于数字都会不太敏感，建议大家记笔记的时候有针对性地留意数字信息，刻意捕捉自己不熟悉的内容。

In the lecture, the professor is skeptical about the idea of the reading passage that new regulations are unnecessary and might have negative consequences. The professor argues that strict rules should be adopted for handling and disposing coal ash.

In the reading passage, effective regulations have already existed and the liner is required to be used. On the contrary, the professor says that the current regulations are not sufficient. Liners are only used in new landfills or ponds rather than old landfills or ponds. The harmful chemicals from coal ash leaked into ground water and contaminated drinking water. We need stricter new regulations that will prevent environmental damage.

The professor then opposes the reading's idea that the recycling of coal ash may stop. The professor states that strict rules won’t stop consumers using recycled coal ash products. The professor takes mercury as an example. Mercury has been recycled for over fifty years with strict rules.

Finally, the professor disproves the reading's idea that the cost of disposal and handling may increase and so the price of electricity will increase. The professor points out that although the cost will increase, when it comes to the average consumers, it will only increase the bill by one percent. It is not a big price.

The passage mainly talks about the opinion of power companies that they don't need new regulations about coal ash that may bring negative results because of the existing regulations, concerns about recycling coal ash and increased cost.（综合写作跟独立写作有一些区别，这种引入句可以省略） the lecturer is against the idea for three following reasons.

First, the passage puts forward the point that regulations did exist, such as using liner-special material in newly-built ponds to prevent environmental contamination. On the contrary, the lecturer casts doubt on this point for the insufficiency of the rule. The liner-special materials are only used in new landfills and ponds. When it comes to the old sites, they still do significant damage to the environment by leaking harmful chemicals into the ground water thus impacting drinking water. Apparently, the existing regulation does not work for old site and environmental pollution is still happening. So the new regulations covering both new and old sites should be created.

Second, another crucial point in the reading part is that adopting strict rules will rise concerns of consumers about the safety of recycled coal ash so that recycling coal ash will be negatively affected. Conversely, the lecturer challenges this point by using an example of another dangerous chemical. Some severe regulations about its storage and handling were created. However, consumers did not have much concerns about it and still buy the cycled products, which recycled for 50 years. So there should be no worries about the consumers' negative reactions to the new strict rules about coal ash.

Lastly, the writer of the passage claims that strict new rules will bring about increased cost in disposal and handling so that the power companies have to raise the price of electricity, which may be unacceptable to the public. Whereas the lecturer insists an opposite opinion that the extra costs of those companies are well-worthy. Although power companies implementing new rules increase their cost about 15 billions, consumers actually will only get 1% more on their household electricity bills. It’s apparently worth paying more for the clean environment.
