C. E-commerce can be more profitable than traditional commerce.
参考答案:C
答案解析:[解析] 23-30
F: The development and expansion of the Internet has made business opportunities available to nearly everyone. In the past, opening a business was a huge commitment in terms of finances and risk. Traditional business owners had to quit their current jobs, obtain bank financing, and sign leases before they even made a penny. It is easy to see why 95% of them failed within five years. Today, business opportunities are available to anyone willing to put in their time and effort to learn about the world of e-commerce. Best of all, you can start an e-commerce business with minimal funds and very little risk. e-commerce is very popular in today’s business world, so what benefit can e-commerce bring to people
M: If you want to expand your business but don’t want the expense of adding new locations, you may want to set your sites on the Internet. Extending your brick-and- mortar or mail-order business to the Internet can speed expansion.
F: Sounds interesting, so can we add E-commerce to our existing business
M: Yeah, adding e-commerce to your existing business can help you: extend your reach to customers around the world; offer a wider variety of products; entice new customers to visit a retail location.
F: How can we start an e-commerce
M: Well, the first step to creating your own e-commerce business is to find you niche. Examine your hobbies and interests for potential business ideas. You may also consider opening a business that is similar to your current job. For example, as a nurse you may know a lot about medical supplies and how hospitals obtain them. You could start a medical supply business. Your contacts and industry knowledge could give you an advantage over a competitor who does not know the inner-workings of hospitals the way you do. You should register a domain name. Take advantage of any brand recognition and name awareness you’ve already built by using the name of your existing company for your domain name. However, if the name is already taken, you’ll need to come up with an alternative that fits with your corporate identity.
F: How can we know the name is available or not
M: OK, you can check on the availability of names and register at GoDaddy. com, Register. corn or MyDomain. com. Then you should select a hosting service. Be sure to select a hosting service that’s geared to e-commerce and includes adequate server space, email aliases and security systems to protect customer data.
M: A good place to start is with the company that currently provides your business Internet and email services. Some website offer comprehensive hosting packages designed especially for small businesses.
F: But how about Building a Web site, we are not professionals.
M: Web site design has been simplified thanks to user-friendly software programs that let you choose from a number of templates. If you don’t feel comfortable taking on this task, or you don’t have the time, hire a designer to take the lead. No matter who takes on design duties, make sure your site reflects your existing brand.
F: We heard a lot of people doubt e-commerce; customers are worried about the hackers and service of our site.
M: Develop a privacy policy and secure means of accepting payment online so customer data is protected and customers feel like they can trust you.
M: Develop customer service policies that mirror the level of service you provide in your existing business. Set policies regarding returns, such as if you’ll allow customers to return items purchased online to one of your retail locations. Implement customer service options such as Web-based, email or toll-free telephone support.
F: That sounds great.
M: We should also offer customers flexible and convenient ways to pay by accepting both paper and plastic and establish the means to accept and track online payments. Start by adding an Internet merchant account to your existing merchant account at your bank. This will allow you to accept online credit card payments.
F: OK, thank you. At the end of the program, can you give us some tips or tactics on online business
M: Well. You may spend some time on search engine optimization strategies to improve your site’s visibility. You can advertise special online-only sales in your retail locations to drive traffic to your site. You can also incorporate your website into your existing offline marketing and advertising strategies.
23. 原文中提到“If you want to expand your business but don’t want the expense of adding new locations,you may want to set your sites on the Internet”,所以A是正确的,后面又提到“internet commerce”能够加速扩张“speed expansion”,说明B正确,C项没有说明,属于多余信息。
