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

Recently I was invited to a friend's house for supper — and had a meal I have never had before.
All the friends invited were a little1It's not that Ben is unsociable, or a bad cook, but it's just that he never 2more than he has to. So how come he was inviting us round for a meal?

We all sat down and looked 6at each other — what did he7to?
Ben returned with four bowls of hot soup. “It's a 8of carrots, potatoes and tomatoes,” said Ben. The next 9was also a little strange in that we didn't quite know what it was again. It's just 10mixture of vegetables.
As we ate we chatted and finally the11turned back to what we were eating. “Was there a recipe(食谱)for this,” asked Marina , “or did you 12it up?” Ben put his fork down. “What I cooked 13what I could find.” Marina was surprised. “But you can find anything in supermarkets these days.” “But there's 14choice in what you can find 15supermarkets,” he replied.

So Ben had19provided a decent (不错的) meal for his friends, and made us aware of the fact that there are many poor people who need the food, but the amount of food thrown away is enough to 20millions of people.
