9月4号更新,在8楼求批改求建议~~~~~~~~~~~~
9.3:
求宝贵建议,谢谢~!感觉自己句式还不丰富,不善变化。。。
原文和提纲如下:
1. 作者假定90天足够长,并且大部分时间都在使用暖气;还假定天气预报很准确很权威
2. 假定新家都会安装并使用oil。但其实可能会有新能源如电暖,出于环保。
3. 假定公司会获利,投资有必要。但其实可能有其他巨头公司,很难再打开市场了。
In this argument, the arguer believes that the demand for heating oil will increase and investment in Consolidated Industries (CI) is needed. While this may seem reasonable at first glance, the conclusion is based on invalid assumptions.
First of all, the author assumes that the climate in the next few years will remain nearly the same. This means, at first place, the author believes that people are using the heating system in the 90 days with below-normal temperatures. This is not convincing because we do not have relating statistics. We do not know the exact temperature. Maybe in reality it was not cold at all and it was not necessary to use the heating system, or they only used it for a week. Another statement is based on the prediction of climate forecasters. The arguer holds the assumption that the result of the prediction is precise and thus the climate will not experience apparent changes. However, we lack information about which institution the forecasters are from and what method they used to predict. Maybe the result is just from a group of college students who are interested in meteorology. According to our experience, we can feel that the climate is changing every year. It is difficult to determine the climate of next year, not to say of the next several years.
Moreover, the arguer implies that the new homes will be equipped with heating equipment and they will use it when it turns cold. This is also unwarranted. On the one hand, some poor families could not afford the heating system and they will not have it in their new house. So, while there are more houses, there may not be more demand for the fuel. On the other hand, in order to protect our environment, some families may choose to reduce their dependence on heating. They prefer to do more exercise to keep warm. It is also possible that oil will be replaced by new types of energy, like power, which may be cheaper and more eco-friendly. Without information of these possibilities, we are not sure whether the demand of oil will go up.
Furthermore, the author suggests investment in Consolidated Industries based on the assumption that the company will make profits in this region. There may have been, however, several big companies supplying oil for family heating before CI enters this region. Therefore, it will be difficult for CI, a new company, to open its market because of too much competence. Even it has proportion in the market, maybe two years later oil will not be the major fuel for heating, and these companies will close. Then the investment may be a waste of money. To strengthen his argument, the author had better do more market research before drawing a conclusion.
All factors taken into account, the author’s argument is not based on sound reasoning. The prediction of more demand for heating oil and the recommendation of investment are not yet tenable. In order to support his opinion, the author should provide evidence which is more persuasive.
