Identifying Topic Sentences (10%) (2%*5)Directions:In this section, there is a passage with some sentences having been removed. Choose the most suitable sentence from the list A-E to fit into each of the numbered blank.Evaluating Sources (来源) of health InformationDeveloping the ability to evaluate reasonably and independently about the health problems will serve you well throughout your life.1.A key first step in bettering your evaluation ability is to look carefully at your sources of healthy information. Reasonable evaluation includes knowing where and how to find relevant information, how to separate fact from opinions, how to recognize poor reasoning, and how to analyze information and the reliability of sources. The following suggestions can help you sort through the health information you receive from common sources.2.Media reports often simplify the results of medical research. Find out for yourself what a study really reported, and determine whether it was based on good science. Think about the type of study. And examine the findings of the original research.3.Some studies will find that a behavior “contributes to” or is “associated with” an outcome; this does not mean that a certain course must lead to a certain result. Be aware that information may also be incorrectly explained by an author’s point of view. Carefully read or listen to information in order to fully understand it and stay away from misleading information.4.If a report seems too good to be true, probably it is. Be especially careful of information contained in advertisements. The goal of an ad is to sell you something. Evaluate “scientific” statements carefully, and be aware of quackery(江湖骗术).5.Friends and family members can be a great source of ideas and inspiration, but each of us needs to find a healthy lifestyle that works for us.
