16、in red as well as in yellow and white, with its bright and gorgeous blossom. The Flower Show, which displays into full the varieties and technological research of the flower, marks the largest one in our city in recent three years. In order to enable the vegetation lovers to embrace Camellia, the fl

17、ower show extends its place to the whole garden, making it more convenient for the visitors. The Flower Show lasts for two months and more than 200 types of camellia will make its appearance during the period. Translation English to ChineseAt its heart, psycholinguistic work consists of two question

18、s. One is, What knowledge of language is needed for us to use language? In a sense, we must know a language to use it, but we are not always fully aware of this knowledge. A distinction may be drawn between tacit knowledge and explicit knowledge. Tacit knowledge refers to the knowledge of how to per

19、form various acts, whereas explicit knowledge refers to the knowledge of the processes or mechanisms used in these acts. We sometimes know how to do something without knowing how we do it. For instance, a baseball pitcher (投手) might know how to throw a baseball 90 miles an hour but might have little

20、 or no explicit knowledge of the muscle groups that are involved in this act. Similarly, we may distinguish between knowing how to speak and knowing what processes are involved in producing speech. Generally speaking, much of our linguistic knowledge is tacit rather than ein economic activity- the s

21、haring economy. The biggest sector of the sharing economy is travel. You find a potential host through a website. If you both get along and they are available during your planned trip, you stand a chance of getting a place for free. In addition, people also use website and apps to rent out their car

22、s, houses, tools, clothes and services to one another. Time magazine has included this trend in a list titled “10 ideas that will change the world.” It said, “ In an era when families are scattered and we may not know the people down the street, sharing things-even with strangers weve met just onlin

23、e-allow us to make meaningful connections.” What do you think of Times comment? era when families are scattered and we do not really know the people who live nearby. It has been said that “Joys shared with others are more enjoyed.” However, in my eyes, the resources shared with others are more benef

24、icial to our society. On the one hand, sharing economy leads to a more efficient use of resources. Some items are expensive to buy but widely owned by people who do not make the best use of them. Occasional sharing may provide extra income for the owners and can be less costly for the borrowers. If

25、managed well, a win-win situation is achieved for both parties in the process. Besides, sharing economy contributes to environmental protection. Take accommodation for example. The more hotels are built, the more resources are required, which might in turn result in a decrease in arable land and pub

26、lic green space. On the other hand, the transaction cost is reduced due to the use of Internet and various apps. With a smart phone in your hand, it is not difficult to find a potential host in the neighboring area. People are meeting increasingly on screens, discussing online and purchasing goods d

27、omestic and overseas, paying through Internet payment system. To summarize, although the sharing economy is not perfect at present because of concerns in insurance, legal liability, safety and the like, I believe, quite firmly, that it represents the future trend and has the power to change the worl

28、d for the convenience and flexibility it brings to us. Just as the old Chinese saying goes, the defects cannot obscure the virtues of a splendid jade, and I assume it also applies to the sharing economy My Views on the Sharing Economy The sharing economy refers to the economic pattern in which peopl

29、e share access to resources, such as goods, services and data. This newly emerging trend would be impossible without the development of technology. It is the Internet that makes the sharing cheaper and easier and helps to strike a balance between supply and demand. Time magazine has listed the shari

30、ng economy as one of the “10 ideas that will change the world”. As far as the comment is concerned, I cannot agree with Time more. As one of the greatest benefits of the digital age, the sharing economy arises from our oldest instinct as human beings. There is always an urge for us to connect with o
