　　Conversation one。

　　M：(1)Do you mind taking my photo with the statue over there? I think it will make a great shot。

　　W：Sure。 No worries。 You‘re always taking photos。 What do you do with all the photos you take?

　　M：Well， don‘t laugh。 My dream is to become an online celebrity of sorts。

　　W：You‘re not serious， are you?

　　M：I am completely I just got the idea a few months ago after posting some holiday photos on my social media accounts， a lot of people like my photos and started asking me for travel tips。 So I figured i‘d give it a go。 I post a lot on social media anyway。 So i’ve got nothing to 。

　　W： I guess that‘s true。 So what you have to do to become internet famous 。

　　M：Surprisingly， a lot more than I did as a hobby recently。 I‘ve been spending a lot more time editing photos， posting online and clearing storage on my phone。 It’s always full。 Now that doesn‘t sound like too much work。

　　W：Well， there‘s more to it。

　　M：I spent all last weekend researching what topics are popular， what words to use in captions and similar accounts to follow really was a lot to take。 And I was up well past midnight。 I‘d say it’s paying off， though I increased the number of people following my accounts by fifteen percent already。

　　W：That is impressive。 I guess I never thought much about all the effort behind the scene。 Now that I think about it， there‘s always something wrong with my photos。 As it is， half smiles， closed eyes， messy hair。 I hope you have better luck than I do。 Then。 Again， I think the only person interested in my photos is my mum。

　　Question 1。 What does the man asked the woman to do?

　　Question 2。 What does the man dream of?

　　Question 3。 What has the man been busy doing recently?

　　Question 4， what does the woman say about her photos?

　　Conversation two

　　M：(5)Good evening and welcome to physics today。 Here we interview some of the greatest minds in physics as they help us to understand some of the most complicated theories。 Today。 I‘m very pleased to welcome doctor melissa phillips， professor of theoretical physics。 She’s here to tell us a little about what it is。(6) She studies doctor phillips。 You seem to study everything。

　　W：(6)I guess that would be fair to say I spend most of my time studying the big bang theory and where our universe came from。

　　M：Can you tell us a little about that?

　　W：Well，(7) i‘m very interested in why the universe exists at all。 That may sound odd， but the fact is at the moment of the big bang， both matter and antimatter were created for a short time， and I mean just a fraction of a second。 The whole universe was a super hot soup of radiation filled with these particles。 So what baffled scientists for so long is why is there a universe at all?

　　M：That‘s because matter and anti matter are basically opposites of each other。 They are exactly alike， except that they have opposite electrical charges。 So when they collide， they destroy each other。

　　W： Exactly。 So during the first few moments of the big bang， the universe was extremely hot and very small matter。 And the now more exotic anti matter would have had little space to avoid each other。 This means that they should have totally wiped each other out， leaving the universe complete。 De baron。

　　M：(8)But a recent study seems to point to the fact that would matter。 And anti matter were first created。 There were slightly more particles of matter which allowed the universe we all live in to form

　　W：exactly because there was slightly more matter。 The collisions quickly depleted all the anti matter and left just enough matter to create stars， planets， and eventually us。

　　Question 5。 What does the man say is physics today?

　　Question 6。 What is the woman physicists? Main research area?

　　Questions 7。 What is the woman interested in?

　　Question 8。 What seems to be the finding of the recent study?

　　Passage 1

　　In this week‘s edition of special series on bizarre medical conditions。 There’s a report of the case of Michelle Myers。 Myers is an American woman who woke up one day speaking with a British accent， even though she‘s lived in the united states all her life in two thousand fifteen， Myers went to bed with[9] a terrible headache。 She woke up sounding like someone from England。 Her British accent has remained for the past two years previously， [9]Meyers had woken up speaking in Irish and Australian accents。

　　However， on both of those occasions， the accents lasted for only a week。 Myers has been diagnosed with foreign accent syndrome。 [10]It‘s a disorder in which a person experiences a setting change to their speech so that they sound like they are speaking in a foreign accent。 The condition is most often [10]caused by a stroke or traumatic brain injury。 Although people with the syndrome have intelligible speech， their manner of speaking is altered in terms of timing and tongue placement， which may distort their pronunciation。 The result is that they may sound foreign when speaking their native language。

　　It‘s not clear whether Myers has experienced a stroke or other brain damage， but she also has a separate medical condition which can result and loose joints easily bruised skin and other problems。 Foreign accent syndrome is rare， with only about sixty cases reported within the past century。 [11]However， a different American woman reportedly spoke with the Russian accent in two thousand ten after she fell down the stairs and hit her head。

　　Question 9。 What happened to Michelle Myers One day?

　　Question 10。 What does the passage say about foreign accent syndrome?

　　Question 11。 What accent did another American woman speak with after a head injury?

　　Passage 2

　　There is something about water that makes it a good metaphor for life。 That may be one reason why so many people find relief in swimming when life seized get rough。 And [12]it goes some way towards explaining why books about swimming， in which people tackle icy legs， race and rivers， and overcome oceans while reflecting on their lives have recently become so popular。

　　These books reflect a trend particularly strong in Britain， where swimming in pools is declining， but more and more folks are opting for open water。 While swimming seems to be especially popular among women。 [13]Jenny landreth recently published a guide to the best swimming spots in London。 Her new book swell into weaves her own story with a history of female pioneers who accomplished remarkable feats paved the way for future generations。 [14]Notions of modesty restricted women in the Victorian era， but they still swam。 A bathing machine was rolled down to the sea shore， so women would not be seen in swim wear in 1892，[14] the gentle woman‘s book of sport described a woman swimming in a heavy dress， boots， hat， gloves and carrying an umbrella。

　　Eventually swimming became freer。 Mixed bathing was permitted on British beaches。 In 1901， women won the right to swim in public pools， learn to swim properly， created appropriate swimwear， and in time even competed against men。 [15]The first woman to cross the English channel was Gertrude Elderly。 In 1926， she beat the record by almost two hours and her father rewarded her with a red sports car。

　　Question 12。 What has become so popular recently?

　　Question 13。 What did Jenny Landreth do recently?

　　Question 14。 What do we learn about women in the Victorian era?

　　Question 15。 What does the passage say about Gertrude?

　　Recording One

　　Today I‘m going to talk about a very special kind of person。 Psychologists call them masters of deception。 Those rare individuals with a natural ability to tell with complete confidence， when someone is telling a lie。 (16) For decades， researchers and law enforcement agencies have tried to build a machine that will do the same thing。 Now， a company in Massachusetts says that by using magnetic brain scans， they can determine with 97% accuracy whether someone is telling the truth。

　　They hope that the technology will be cleared for use in American courts by early next year。 (17)But is this really the ultimate tool for you? The lawyers of tomorrow? You will not find many brain scientists celebrating this breakthrough。 The company might be very optimistic， but the ability of their machine to detect deception has not provided credible proof。 That‘s because the technology has not been properly tested in real world situations。 In life， there are different kinds of lies and diverse contexts in which they’re told。 These differences may elicit different brain responses。

　　Does their hypothesis behind the test apply in every case? We don‘t know the answer， because studies done on how reliable this machine is have not yet been duplicated。 Much more research is badly needed。 Whether the technology is eventually deemed reliable enough for the courts will ultimately be decided by the judges。 Let’s hope they‘re wise enough not to be fooled by a machine that claims to determine truthfulness at the flip of a switch。 They should also be skeptical of the growing tendency to try to reduce all human traits and actions to the level of brain activity。 Often， they do not map that easily。

　　Moreover， understanding the brain is not the same as understanding the mind。 Some researchers have suggested that thoughts cannot properly be seen as purely internal。 Instead， thoughts make sense only in reference to the individuals external world。 So while there may be insights to be gained from matching behavior to brain activity， those insights will not necessarily lead to justice in a court of law。 Problems surround the use of machines to spot deception， at least until it has been rigorously tested。 (18)A high tech test that can tell when a person is not telling the truth。 Sounds too good to be true。 And when something sounds too good to be true， it usually is。

　　Question 16。 What have researchers and law enforcement agencies tried to do?

　　Questions17。 How do many brain scientists respond to the Massachusetts companies so called technological breakthrough?

　　Question 18。 What does the speaker think of using a high tech test to determine whether a person is telling the truth?

　　Recording Two

　　Last week， I attended a research workshop on an island in the South Pacific。 Thirty people were present， and all except me came from the island called Mcclure in the nation of Vanuatu。 They live in sixteen different communities and speak sixteen distinct languages。 In many cases， you could stand at the edge of one village and see the outskirts of the next community。 (19)Yet the residents of each village speak a completely different language。 According to recent work by my colleagues at the Max Plank Institute for the science of human history， this island， just one hundred kilometers long and twenty kilometers wide， is home to speakers of perhaps forty different indigenous languages。 (20)Why so many? We could ask the same question of the entire globe。 People don‘t speak one universal language or even a handful。 Instead， today， our species collectively speaks over seven thousand distinct languages， and these languages are not spread randomly across the planet。 For example， far more languages are found in tropical regions that in the milestones。 the tropical island of new guinea is home to over nine hundred languages， Russia， twenty times larger， has 105 indigenous languages。

　　Even within the tropics， language diversity varies widely。 For example， the two hundred and fifty thousand people who live on Vanuatu’s eighty islands speak 110 different languages。 But in Bangladesh， a population six hundred times greater speaks only 41 languages。 How come humans speak so many languages? And why are they so unevenly spread across the planet? As it turns out， we have few clear answers to these fundamental questions about how humanity communicates。 Most people can easily brainstorm possible answers to these intriguing questions。 They hypothesized that language diversity must be about history， cultural differences， mountains or oceans dividing populations。

　　But when our diverse team of researchers from six different disciplines and eight different countries began to review what was known， we were shocked that only a dozen previous studies had been done， including one we ourselves completed on language diversity in the Pacific。 These prior efforts all examine the degree to which different environmental， social， and geographic variables correlated with a number of languages found in a given location。 The results varied a lot from one study to another， and no clear patterns emerged。 The studies also ran up against many methodological challenges， the biggest of which centered on the old statistical saying， “Correlation does not equal causation”。

　　Question19。 What does the speaker say about the island of Mcclure?

　　Question 20。 What do we learn from the talk about languages in the world?
