Unit 4 Astronomy：the science of the stars.閱讀理解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 topicsstories 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(虛假的) 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，F(xiàn)acebook 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 linedon't believe every word of what you read.Do more research from multiple (多樣的) sources to ensure that the news is indeed true before you share with others.語(yǔ)篇解讀本文為一篇說(shuō)明文?，F(xiàn)在社交媒體充斥著大量虛假信息，這些信息的傳播對(duì)人們的生活危害很大。為了治理這種現(xiàn)象，一些社交媒體已經(jīng)采取了一些措施。1What does the underlined word “aggregate” in Paragraph 3 probably mean?AAnalyze.BCancel.CGather.DRewrite.解析：詞義猜測(cè)題。根據(jù)第三段最后一句可推知：社交媒體經(jīng)常根據(jù)用戶的瀏覽、搜索信息為用戶收集信息，由此可見aggregate意為：gather(收集)。analyze“分析”；cancel“取消”；rewrite“改寫”。答案：C2What can we infer from Paragraph 4?APeople tend to believe the news on social media.BFalse news is fashionable on social media.CFalse stories are shared quickly across social media.DMisleading information harms us.解析：推理判斷題。根據(jù)第四段中的“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.”可知：誤導(dǎo)人的信息對(duì)我們有害，故答案為D項(xiàng)。答案：D3How will Facebook deal with false news?ATo label fake contents to warn.BTo forbid advertising on its network.CTo prove the news from multiple sources.DTo close down the sites of false news.解析：細(xì)節(jié)理解題。根據(jù)第五段“This would include warning labels on fake contents.”(這包括給虛假信息做上警示標(biāo)記)可知答案為A項(xiàng)。答案：A4What might be the best title for the text?AKeep Away from Fake NewsBNever Blindly Believe Anything You ReadCRefuse to Spread Harmful InformationDSeparate Truth from Fiction Skillfully解析：標(biāo)題歸納題。本文主要介紹了現(xiàn)在一些社交媒體中充斥著大量的虛假信息，這些信息對(duì)人們有很大危害。因此作者告誡讀者不要盲目相信媒體上的信息，在傳播信息之前一定要確保信息的真實(shí)性。由此可見B項(xiàng)最適合作為本文的題目。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 Tzompas­Sosa，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 heart­healthy omega­3 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 protein­rich 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 Tzompas­Sosa.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.語(yǔ)篇解讀本文是一篇說(shuō)明文。主要介紹了食用昆蟲的問題。文章指出了食用昆蟲的好處，同時(shí)指出有些昆蟲在使用前還需進(jìn)一步測(cè)試以確保其安全性。5What is the author's attitude towards the use of bug oils?ADoubtful.BObjective.CSupportive.DUnfavorable.解析：推理判斷題。作者只是客觀陳述了食用昆蟲的問題，并沒有給出自己的觀點(diǎn)，故本題答案為B項(xiàng)。答案：B6Which of the following can replace the underlined phrase “Backing up”in Paragraph 3?ARaising. BRejecting.CSupporting.DEnjoying.解析：詞義猜測(cè)題。根據(jù)第三段“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.”可知聯(lián)合國(guó)糧食和農(nóng)業(yè)組織支持食用昆蟲，故答案為C項(xiàng)。答案：C7Why do experts suggest eating the insects?AThey're rich in minerals.BThey have different colors.CThey taste good.DThey're easy to raise.解析：細(xì)節(jié)理解題。根據(jù)倒數(shù)第三段“Experts say insects require little food to grow and the backyard can be a good place to raise them.”可知，專家們認(rèn)為昆蟲需要很少的食物去飼養(yǎng)，并且自家院落就可以養(yǎng)殖，因此可知，昆蟲很容易飼養(yǎng)，故答案為D項(xiàng)。答案：D8From the last paragraph，we can learn that .Aall insects cannot produce good oilBthe bug oils are the most deliciousCit's safe to consume the bug oils Dthe use of bug oils is banned解析：細(xì)節(jié)理解題。根據(jù)最后一段“But not all insects produce good oil.Cockroaches don't.”可知，食用昆蟲還需測(cè)試，并不是所有的昆蟲都適合食用，因此答案為A項(xiàng)。答案：A.完形填空I have written a poem called Flying Kites，in which a man 1 his son to fly a kite.After a few minutes，the child 2 drops the string and lets the kite soar(高飛)With joy in his eyes，he watches it climb until it disappears 3 .The father realizes that 4 he'll have to loosen the tie that binds (綁) him to his son.And he 5 “Will I release the string as unselfishly as that？”Many years later my son，Gary， 6 he wouldn't finish his college career.I tried to talk him out of it.But none of my reasoning made any 7 .At the end of the semester Gary moved back home.Gary managed to find a 8 at a nursery and went at it with usual enthusiasm.I， 9 ，was deeply disappointed.What was a college professor's 10 doing at a job that any high school dropout could perform?
