Ⅰ.阅读理解AHow often have you read a story that a friend or family member has sent you？Very likely you would have skipped the news had it not been pointed out to you.Traditionally newspapers and famous TV channels have been our source of authentic news.But these days with the popularity of social media，sharing stories is increasingly becoming a favorite source of news.In fact，research suggests that more than half the people get their news today from social media such as Facebook，Twitter and Google.Social media sites often aggregate contents for us to see based on trending topics—stories that have been viewed by many others as well as based on our own past searches and analysis of our likes and dislikes.If you have liked kittens in the past，you may have noticed that you are seeing more news，blogs and analysis about kittens all of a sudden.While advocates of free speech do not want to control any voice，it is certainly harmful when it is difficult to separate truth from fiction.Imagine the influence of fake(虚假的) news when it begins to affect our own lives.Trusting a piece of news，patients could very easily fall for wrong diagnosis; elders could give money to cheats and reputation of perfectly upright citizens could be easily ruined.What about when we research for a school project and base our analysis on false information or news?Mark Zukerberg has finally acknowledged the issue.Among several projects that the company is considering，Facebook is trying to take powerful measures to crack down on false news.This would include warning labels on fake contents.Fake news also makes a lot of profits from advertising.Google and Facebook have said they will limit advertising profits on their network from such sites.The bottom line—don't believe every word of what you read.Do more research from multiple (多样的) sources to ensure that the news is indeed true before you share with others.[语篇解读]本文为一篇说明文。

答案：BBRun out of cooking oil or need some dressing for your salad？The solution may be insects from your backyard！Scientists are turning insects into a source of healthy oil.Even though insects are a food source in some parts of the world，to many people，the thought of eating them is very disgusting.“In the western countries，there is no culture of eating entire insects，so when the idea is to use the protein in powder as an ingredient，people might tend to receive this protein better even if they cannot see it，”said researcher Daylan Tzompas-Sosa，Wageningen University，Netherlands.“There are many uses for the oil in general，but we are investigating the use of these oils for a food，as a food ingredient.”The Mexican researcher，working in the Netherlands，said insects are a great source of heart-healthy omega-3 fatty acids，which can help treat anxiety disorder symptoms.Backing up the increased reliance on insects is the United Nations Food and Agriculture Organization.In a 2013 report，the UN agency allowed the cultivation of bugs as a food source，saying it's environmentally friendly and could boost the world's food production.There are clear reasons why experts advise people to eat the insects.Experts say insects require little food to grow and the backyard can be a good place to raise them.And there's no shortage of protein-rich insects，which contain fat，vitamins，fiber and minerals.Researchers say different bugs provide unique tastes and textures.“This is very liquid and it has a different color，so this can be used as a dressing for example and it's easy to use and this can be used for example for pastry，because for pastry you need hard fats，”stated Tzompas-Sosa.But not all insects produce good oil.Cockroaches don't.The bug oils must be tested to make sure they are safe to consume.But getting over the “ick factor” may be a bigger challenge.[语篇解读]本文是一篇说明文。
