【题目】根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Going online to do research when you're writing papers and doing projects is natural thing to do. Knowing how to evaluate and choose online resources can help you avoid headaches and wasting time.
How can you make researching online as easy and effective as possible? Before you begin your research, make a list of the kinds of sites that are best for your topic. Is the website reliable and up to date? Government sites ending in . gov and educational sites ending in .edu usually are safe bets. Established news-related sites are OK, too, but be sure that you're using the original source. If a newspaper article mentions another source, like an organization or website, go directly to that source to find the information.
They can be good resources, but it's always best to check with your teacher to make sure he or she considers the site appropriate. Wikipedia. Org is popular and ranks highly in search results, but it can be edited by anyone, whether a person has accurate knowledge of the topic or not.
On commercial websites ending in .com, check to see if the site has advertising. And bogs, personal websites and social media sites are more likely to give personal opinions rather than facts.
A. Check to see if the author is identified and sources are given.
B. That's why it helps to know the best sites for your needs.
C. But all of the choices at your fingertips can seem overwhelming sometimes..
D. Sites ending in .org are usually run by non-profit organizations.
E. Many schools block access to images or websites that may be valuable to your research
F. At most schools, using Wikipedia as a source is not a good way to build credibility.
G. If it does, it may be biased(有偏见的), since it's trying to sell a product
