昨天刚加入,写了一版,但是没有权限发上来,今天补发,规定时间内敲完,字数还有待提高 11.2 综合
To protect a type of evergreen trees, three possible solutions have been put out by experts to address the decline of Torreya. However, in the lecture, the professor claims that none of them can be useful to achieve that goal. She defused the possibilities listed in the passage one by one.
Firstly, the first option is to reestablish Torreya in the same location with a specific microclimate. But, according to the professor, the climate condition in this region has been totally changed, for the reason of global warming, which makes the over temper all over the world and the wetland in Florida has been drained, causing the area to be much dries. The condition in the area nowadays is not suitable for the trees to survive anymore.
Secondly, moving Torreya to an entirely different area can bring in many unpredicted results. As the professor said, one kind of tree called Black Locust killed many species of trees in the north when it had been moved northwards. To make the situation worse, those species of trees have already been in danger. Introducing Torreya may also lead to this kind of unexpected problems.
Finally, the last option to preserve Torreya in research center is also not useful because the research center is not able to provide the large capacity for large genetically diverse, which is necessary for the trees to survive against diseases.
To sum up, all the trees options presented in the reading passage is not practical in the real situation. Not only are they unable to protect Torreya from decline, but also they can cause more losses in the end.
11.2独立 People should buy things made in their own country;even the price is higher than same things made somewhere else
提高产品质量 更多的选择 价格更加便宜,提高了消费者的购买力,没有必要多花钱
Nowadays, due to the opening reform of many countries, the boundaries of countries have been more and more ambiguous. However, there is a big issue coming up that whether people should buy their domestic things, even the price is higher than same things made in other countries. As far as I am concerned, I hold the positive view for the free exchange of goods and services internationally, by the same token, people needn't protect their domestic things from competition with others for the following reasons.
Firstly, opening the gate of countries allows technology to flow among different countries, which will improve the qualities of basket of goods people can consume. For example, some countries like German and Japan have more advantages in producing digit products. When other countries borrow the technology from them, it is a much easier and cheaper way to improve their domestic products.
Secondly, sharing the products provides people more choices. For instance, before the reform of opening in China, people consume all the things produced domestic, wasting those overproduced, such as clothes, cotton, and lacking those that cannot be produced due to the limit of technology, like the Internet. It is a huge waste of resources in the world. Thanks to the police of opening reform, Chinese people can enjoy the convenience of Internet, charting and making friends with people from all over the world, and at the same time, western countries can purchase clothes importing from China much cheaper.
Finally, it is of no necessity to spend excess money to buy the same goods which are available in other areas. Most importantly, it is not a wise to decrease the purchasing power of people to protect domestic goods from competition in the world. Consumers have the rights to choose what they want to buy. Why should they spend more money to buy something that is not superior for them?
To sum up, considering consumers' interest and countries' technology improvements, there is no need for people to only buy goods domestically. Governments have not rights to help their people make the choice. Besides, wise people are always those who make full use of their money, to maximize their own interest. Seeing from the other angle, the more competition there are, the stronger the motivation the producer will have to provide us better products.
