单选题Communication is the lifeline of modern business. Without it business cannot function. Every transaction (交易) needs communication. The objective of business is to produce and sell for a profit goods and services that satisfy society's needs and wants. Such goods and service are made available in a market. It is at the market that supply and demand are achieved in a purchase-sale transaction at a specific price. The profit is the seller's motive to engage in business. Successful enterprise management rests on three basic elements: leadership, motivation, and communication. When a highly successful company begins to go down, it is usually a consequence of incompetent leadership and a failure in communication is often found to be a contributing factor. Marketing is the performance of business activities that direct the flow of goods and services from producer to consumer or user. Simply to produce a product is not enough. The product must be transported, stored, priced, advertised, and sold to satisfy human needs and wants. Communication is a major part of international marketing. The right product must be offered for sale in the right place and at the right time and at the right price. And the right message must be communicated via the right media to the right market targets at the right time. It is necessary to provide the information that buyers need to make purchasing decisions. Marketing activities promote the exchange of goods. A qualified marketer must be a communications specialist.

单选题The challenge of writing a powerful cover letter (附信) can lead job candidates to search endlessly for advice, but be careful. While you likely will find some valuable advice, you may come across a few tips that could mislead you. "You need a lengthy cover letter." This probably is one of the "bad cover letter tips." Think about it: hiring managers have piles of resumes and cover letters to review. If yours is longer than the rest, it might not get read at all. Aim to get all of your points across in three brief paragraphs: a clear introduction that lets employers know which job you are applying for and why you are interested in the position; a paragraph that includes a few specific examples of how you have excelled (擅长) in past roles that are relevant to the open position; and a concluding paragraph that tells employers how you will benefit their company and requests a future meeting. "Your cover letter is less important than your resume." Some hiring managers shove (随手扔) cover letters to the side, but most do not. Because you never know what type of hiring manager you are dealing with, it is best to submit a nice cover letter. While some employers place less emphasis on cover letters, others decide who to interview based on them. Remember that the point of a cover letter is to tell employers something that makes them want to meet you.

单选题Much of a parents" job is to provide the gifts of caring, love and emotional support to children. But one gift is often beyond their reach: the resources to meet the financial demands of tuition.

More than 300,000 students have graduated from United Negro College Fund member colleges since 1944, and 54,000 more are currently enrolled. The oldest and most successful minority higher education support organization, the United Negro College Fund is a combination of 39 private, historically black member colleges and universities. Since its founding, it has raised more than 21.3 billion to keep the dreams alive for needy families across the country. What is it that makes the United Negro College Fund so important to America"s families?
