单选题 Have you ever wondered why authors write? Sometimes they are inspired to create stories. Other times they write to provide information about an interesting topic. Some authors write to convince us about something. Whatever the circumstances, authors have reasons for writing; this is called, the 'author's purpose.' The three most common types of author's purpose are: to entertain, to inform, and to persuade. Think about the last time a story made you laugh, cry, or tremble with fright. These types of stories are written with a particular purpose in mind: to entertain the reader. Authors write many kinds of stories to entertain, including humorous fiction, realistic fiction, fantasy, fairy tales, and fables. While fiction entertains, non-fiction has a different purpose. Many non-fiction writings or texts are written with the purpose of giving information about an interesting topic. Authors who write to inform must research their subject to ensure that they convey accurate information to the reader. Some examples of texts that inform are encyclopedia entries, news articles, expository non-fiction books, and interviews. All of these types of writing give information about certain topics. Sometimes authors write because they want to convince their readers about something. This is called argumentative, or persuasive writing. Oftentimes, texts that are meant to persuade use specific techniques to make the reader care about the subject, and to think about it in a certain way. These techniques might be found in letters to the editor, argumentative essays, or persuasive speeches. Next time you read a text, see if you can figure what the author is trying to tell you. It might be easier than you think. Just ask yourself: what is the author's purpose?

单选题 As part of an ongoing campaign against polyvinyl chloride (聚氯乙烯), a Virginia-based environmental advocacy group today called on manufacturers and retailers to phase out its use in shower curtains. The Center for Health, Environment and Justice (CHEJ), released the results of a small study indicating that PVC (聚氯乙烯)-containing shower curtains are capable of emitting scores of potentially harmful materials, into people's bathrooms. A previous study, conducted by Environmental Protection Agency researchers, also found that plastic shower curtains can emit toxic compounds into the air. There's still debate among scientists about just how serious the health effects are especially at low doses. However, CHEJ urges consumers to avoid using PVC shower curtains, as well as many other PVC products. For people who are concerned about their shower curtains, there are alternatives. IKEA phased out PVC shower curtains 11 years ago, switching to ethylene vinyl acetate (乙烯醋酸检聚物). The company has said that 88 percent of its shower curtains would be PVC free by spring of 2008. Manufacturers are not required to label shower curtains, but some do list 'PVC' or 'vinyl' on the packaging. Numerous online retailers, sell shower curtains—primarily cotton or hemp—that are free of PVC. However, mildew (发霉) can be a problem with cotton and hemp products.
