第37题: [多项选择]
BUILD A WEBSITE Your small shop wants to build a website. You have been asked to submit ideas on how to do business online. Discuss, and decide together: feasibility of building a website for the shop how to run the shop online
参考答案:Interviewer: Well, Liming and Liulili, the last part of this speaking test is a discussion task. Your discussion topic is on this task card. You have about C0 seconds to read it carefully. After you have read the task, you will have a discussion on the given topic. Your discussion time is around three minutes. OK Now read your task card. (C0 seconds later) Well, can you start your discussion now I’m going to listen to you and then ask you to stop at the end of three minutes. Liulili: Well, a new era is upon us. The Internet is fundamentally changing customer value propositions t service-and-fulfillment models and cost structures. I think that the Internet is a tremendously new place to do business. It’s the first new place where anybody can go to explore marketing. It’s also a new medium. It’s a totally new unexplored creative area for people. We can use it as a selling tool. We can see it used very creatively as an advertising tool, as a marketing tool, as a communications tool. I think it’s really a fascinating new place for people to explore. We’d better grasp the chance. Liming: Yes, you are right. The internet is giving business, especially small business owners a big opportunity and special advantage. An online business facilitates communication, collaboration, and the sharing of knowledge with customers, employees, partners and suppliers. Sales on the Internet helps small business compete in the world market. The Internet market is a many-to-many channel, which provides many customers with information about many suppliers. This distinguishes it from extranets and similar arrangements which provide many of the same services but serve a single seller or buyer. And with Internet you are not limited to state or national boundaries. The whole world is your customer base. It is really amazing. I bet people on the Web tend to order more. Liulili: I think so. People on the Web tend to be adventurous anyway. People who might never have thought of ordering hot and spicy foods, because they see it on the Web, take the opportunity to do it. It’s something that’s never occurred to them, but it’s something totally new. Liming: And now it is up to us to come up with the way of dividing our products up, and arrange them in a logical pattern for customers to follow. Otherwise customers may spend a long time searching, and never find out the information they needed. So we can divide them up in some logical ways. Liulili: Good idea. We’d better provide convenience and our wonderful service to our customers. Liming: Net market makes it easier for buyers to evaluate sources, prices and delivery alternatives. Instant choice, easy comparisons, immediate fulfillment will help to shift the balance of power to the buyers. Interviewer: Do you have any suggestion to small businesses who are considering having a web presence Liulili: To start a business on the Internet, there are lots of things that you need to think about. For example, if you’re selling something, you have to remember that you’re now a worldwide company. You will be shipping overseas. You will get order from overseas. Be prepared for that. Liming: And customers on the Net are much more likely to want to contact you than any sort of catalog business. Most catalog businesses have very little contact with their customers. But e-mail is easy. They can e-mail you questions. Customers feel more comfortable doing it. So you have to be prepared to spend a fair amount of time responding to them. Interviewer: Do you think a website enables you to get more businesses Liming: Yes, that really works for a very small shop. We can have our customers all over the world. With the website, we can get orders from all over the world. We have a guy from Germany who ordered for a friend in U. S. We have a guy from England who sends gifts to his family in China. That’s something that small retail establishment could never do in any other way. Liulili: Business online gives small business a big advantage over the typical retail establishment. Now with the Internet, everything is done right from the comfort of the consumers’ home, without going to store, which avoids traffic jam and some troubles. They simply point and click. They like to do that, so more businesses are possible. Interviewer: Thank you, Liming and Liulili. That is the end of the speaking test.
