Public speaking is one of the top three fears among adults in both the UK and the US． Here are some suggestions that deal with some of the most common problems people experience with public speaking．
Invite the attention in
Do you hate that moment when you stand up in front of a group to speak and everybody looks at you？① ． It's a sign that people are interested and want to hear what you have to say． Welcome those looks!
Beat the brain freeze
Have you ever been in the middle of speaking and suddenly……brain freeze!② ． It is possible that you forgot something for the moment． And you are holding your breath! All you need to do is to trust yourself， clear your mind， focus and breathe． The thoughts will come rushing back to your mind in no time． Phew!
Increase your confidence
Use this exercise to get in touch with the "naturally confident （自信的） you" inside． Close your eyes and remember a special time you felt really relaxed and confident． Imagine the feeling of relaxation rushing through your whole body． It will pass information to your brain that you are confident and happy．③ Whether you are someone who just wants to move from good to great with your speaking， or someone who feels too afraid to stand up and speak， the great news is that you can move forward， be relaxed， and turn into a great speaker．④
（2）Write down another suggestion on how to become a good speaker． （答案不多于5个单词）
To help Japanese companies better deal with the increasing number of foreigners visiting the country， Panasonic has created a megaphone （扩音器） which is able to smartly translate Japanese into English， Chinese and Korean．
Panasonic named the product "Megahonyaku"． It is a term for the Japanese words for "megaphone" and "translate"， which actually makes a lot of sense because it's a megaphone that can translate Japanese into several other languages in real time． When a user speaks Japanese into the megaphone， it recognizes （辨认） and translates what is being said immediately， and outputs the words in English， Chinese or Korean．
It sounds amazing， and seeing it in action is wonderful， but Megahonyaku is not good enough． It cannot translate everything you say， as it only stores 300 common expressions， like "The train has been put off" or "Watch your step"． However， the Japanese company behind Megahonyaku promises to add new expressions regularly， which users can get on the Internet．
The machine was designed to be used in places like transport stations， airports and places of interest where quick and exact announcements are needed most． Around 30 Japanese organizations， including the police and guides， have been trying out Megahonyaku for about one year， but Panasonic says it will come onto the market on December 20th． Instead of selling these speech translators， Panasonic plans on renting （出租） them out for less than ﹩183 a month on a three﹣year agreement，and offering users future improvements and necessary services．
Panasonic has also said that it may add support for other languages，like Russian，depending on customers' needs．Megahonyaku also includes a touch screen that allows users to choose the language they need their speech translated into．
（1）Panasonic has produced Megahonyaku so that ．
A．guides can translate Chinese into Japanesefaster
B．Japanese companies can receive foreigners better
C．foreigners can talk with the Japanese freely
D．the Japanese can learn other languages easily
（2）The third paragraph is mainly about the of Megahonyaku．

B．importance
C．disadvantage
D．history
（3）It can be learnt from Paragraph 4that Megahonyaku ．
A．may be popular with the police
B．is widely used in private homes
C．will be sold on December 20th
D．stores about 30foreign languages
（4）According to the passage，Panasonic will in the future．

A zero﹣waste life is a lifestyle that hardly creates any rubbish． So， a zero﹣waste store is about providing a kind of everyday and pleasant﹣looking zero﹣waste products to help people start on a zero﹣waste life journey．
"Zero waste" or "danshari" was first suggested by a French woman called Bea Johnson． Her idea is： live a life and try not to create any rubbish； use different kinds of ways to save the environment such as stopping the use of one﹣off objects； giving unwanted things to others or giving them away to organizations like the Red Cross．
Yu Yuan， 27， is deeply interested in this idea． She and her boyfriend have lived in Beijing for many years． And earlier she used to buy things without thinking about them carefully until she saw a video about "zero waste"， in which a family of four placed the rubbish they produced every year in a jar （罐）． After watching the video， Yu wanted to experience this zero﹣waste lifestyle with her boyfriend．
A zero﹣waste life follows the 6R rule﹣Refuse Reduce， Reuse， Repair， Recycle and Rot． Over August﹣October when Yu followed the rule of zero waste 6R， she and her boyfriend Joe Harvey both produced only two cans of rubbish．
Now， the couple have opened a small shop in Beijing， where they use wood products to take the place of plastic ones and cloth bags printed with environmentally friendly logos． Most products sold in the store can be reused． The store also has second﹣hand books and CDs/DVDs with， ideas to make the best of the used things．
"Those who once experienced the non﹣waste lifestyle have slowly changed their ideas，" says Ya， "The zero﹣waste lifestyle is not for ascetics （苦行僧）． It is just around us at our finger﹣tips．" Yu expects some of her friends to join her on the road to zero waste．

（4）Which of the following is the best title for the passage？

To help more people enjoy Beijing Opera， Ghaffar often teaches the traditional art form in schools in the United States， Britain and other countries． When he found that the language was difficult to understand， he started to translate Beijing Opera song lyrics． Ghaffar led a group of actors to perform 66 times in a month and a half in the United States． He also led a 48﹣member team to perform in Malaysia． In the past 10 years， he has performed in more than 400 shows．

Texting while driving is against the law in 47 states． But what about texting while walking？ A 2018 study reported that more than 2， 500 people in the US ended up in hospitals resulting from using a mobile device（设备） while walking．
Hawaii passed a law making it illegal（违法的） to text or look down at a mobile device while crossing the street． It is the first state with a law like this． Do people think more places should accept such a law？ The LA Times did a survey． Here are some replies they received．
Rena Jose， 2， New York Which is more important， texting or safety？ If you are looking at your phone while walking， you might not see a car come or traffic lights turn red． It can be very dangerous． For example， in Japan， one person fell into a lake and another got her leg stuck in a hole， because both had their mind on their phone． We should make texting while crossing the street illegal in more cities． |
Andy Selvam， 55， California People do many things that cause injury to themselves but are not illegal， such as climbing mountains， driving cars， swimming and so on． People might get hurt from texting and walking if they're not paying attention． But I still think they should have a choice． |
Bob Madigan， 45， Oregon As humans， we can make our own decisions． I'm not saying it's safe， but we don't need the government to babysit us． If we want to learn to make smart decisions， the government needs to stop telling us what to do． After all， this is a free country． |
Andrew Black， 34， Alaska This law is a good idea﹣compare this protection with seat belts． If this law is passed all over US， people will be worried． But is there really a way to please everyone？ This would not be for fun． It would be safe and good for all Americans． |

The world has a plastics problem． And not just with bottles． Straws（吸管）， toothbrushes， toys﹣all kinds of plastics are placed in landfills． There are 5 billion tons of plastic waste in the world． Landfills have a large part of it． By 2050， they could have 13 billion tons．
Much of plastic rubbish finds its way into the ocean． Scientists say 165 million tons of plastic pieces are floating around out there． And most plastic won't disappear itself． It will remain in the ocean forever． Whales get caught in plastic fishing nets． Birds die because of eating plastic straws and bottle caps． It endangers ocean life． Plastic rubbish even ends up in the food we eat．
Governments are realizing that recycling may not be enough． They are taking more actions． Though it is hard work， it is still a solvable problem． In Britain， people are not allowed to use plastic bags except in hospitals． Scotland and several coastal cities in the US stop people from using plastic straws as well． The US alone throws away some 500 million plastic straws a day． That's enough to circle the Earth twice． "Saying no to a plastic straw is an easy way to make a big difference，" Dana Lofflin who started said． "Do we really want to pass on to our children a world harmed by plastic？"
People have found some tasty ways to reduce waste． A company in India made the first﹣ever spoon that people can eat． You don't have to eat the spoon． You can throw it away． It decomposes（分解） in just a few days． David Edwards， a scientist at Harvard University， designed an eatable bag which can protect the food or drink inside． It is a delicious replacement for plastic ones．

"Made in China" is having its moment now﹣and it's a fashionable one．
The story of Chinese fashion began in 2011 when Feiyue and Huili， both Chinese sports shoe brands（品牌）， suddenly got international attention． Their products were seen all over the world． Chinese sportswear brand Li Ning was at the New York Fashion Week in September， 2018． They showed their new designs﹣sweaters and jackets with Chinese characters．
Shaun Rein， managing director of China Market Research Group， said that the latest Chinese brands no longer catch customers' eye by low price． He told CNN， " They are sure that they can go head to head with foreign brands．
Maybe it is because China's young people are now more confident about their own culture． They don't show immediate interest in western culture any more．
"Today's young people in China are crazy about Chinese cultural elements（元素）．" Jin Qu， the manager of a clothing shopping website， said at a cultural festival in 2018． They like these elements printed on their clothes， even the brand picture of Laoganma in China， which was once seen as outside of fashion． But now young people are proud of these Chinese symbols．
"In fact， many stars in the West are now interested in Chinese cultural elements in fashion． Rihanna， a US singer， for example， wore a Chinese red dress to the 2015 Met Gala in New York． The dress was designed and made by Chinese designer Guo Pei．
"We have to move from making to creating，" Chinese﹣American designer Aric Chen once told The New York Times． "We want to replace the words ‘Made in China ' with ‘Designed in China '．"

Big data（数据） is a lot of sets of information that are put together so they can be used by a computer program． The computer program looks for different kinds of answers or patterns in the data． Big data can have different kinds of information from many sources， such as information that comes from schools，social media sites， companies， and governments． One set of data can have people's names and addresses． Another set can have what they like， where they go to school， and how much time they spend on the computer．
Big data can be used in many ways． The government uses it to understand how many people travel on buses or trains． This information is then used to make bus or train systems better． Some schools use big data to understand which children may need extra help in class． The teacher can then give certain students more help or support so those students can succeed in school． Companies use big data， too．It helps them understand who buys their products． For example， one company uses weather data to see when people eat the most ice cream．
Big data can be used for good reasons． Some hospitals use big data to predict if a baby who is born too early will get sick． The hospital can then take extra steps to take care of that baby so he or she does not get sick． Big data can also be used for bad reasons． It can be used to predict which kinds of people are likely to break the law or hurt others， even if they have not done anything wrong．
How can big data be used for good and bad things？ It is because the computer programs used to look at big data and understand it are written by people． People think a certain way． Because they think a certain way， they build a model of those ideas． These ideas are then used to look at the data．Sometimes，these ideas are helpful for people or businesses． Other times， bad ideas can cause problems for certain groups of people．

The year was 1859． America and England had already fought two wars． Now， they were at peace．But one day a pig got hungry． And it nearly caused another war between the two countries．
The pig was owned by a British man who lived on a small island． The island was just off the western part of North America． Both England and the US said the island was theirs． Across the island from the British man lived some American farmers． Everyone on the island got along peacefully． But the peace ended the day the British man's pig decided to eat some of an American farmer's potatoes．
One of the American farmers shot and killed the pig． Then the pig's owner wanted ＄100 from the man who shot the animal． That was a lot of money， so the farmer refused to pay it． The British and Americans began to argue， and the situation got worse． The farmers asked the governor over the island at that time for help． He sent a group of soldiers to protect the farmers． The British answered by sending 2 ，000 soldiers． The British were on one side of the island， and the Americans were on the other． The problem that began with the pig was about to become a shooting war．
When news of the problem reached Washington and London， both leaders were surprised．Neither country wanted another war． They sent some men to try to fix the problem． After a discussion， it was decided that each country would keep a small group of soldiers on the island． They would stay there until the two countries could decide who owned the island． Then the others would have to leave．
Twelve years went by． Neither side wanted to give up the island， but they knew they had to do something． They asked the leader of Germany to help decide． After nearly a year of discussion，a decision was made． America would get the island．

Many people might think that if they had more money， then they would be happier in life． For example，people might look at what others have， like expensive clothes or nice cars， and wish they could have the same． But the things that money can buy can not bring happiness to a person for long．
①But is that really true？ Studies have found that money can， in fact， make people happier． ②Instead， it's giving money to others that makes people happy．③It could be buying a present for a friend or a family member．④It could be buying a homeless person food to eat． It could be giving money to a person in need． Just think about the last time you used your own money to do something for someone else． How did you feel？ Whether it is a small or large amount of money， people feel happier when they give． This is because making someone else happy makes the giver happy， too．
This idea of connecting your happiness to the happiness of others is described as ubuntu in an African language． There is even a story about a man visiting Africa who asked some kids to race to a nearby tree． The first child to touch the tree would get a sweet treat． Surprisingly all the children held hands and ran together． They all touched the tree at the same time． The man asked why they had done this． The children simply said they could only enjoy eating the treat if everyone had one．

On March 10，2019，eight﹣year﹣old Tani won the New York Chess Championship （纽约象棋冠军赛）of his age group． But the boy， who was homeless at the time， began learning the game less than a year ago．
Tani and his family arrived in New York City from Africa in 2017． A church helped him enter the primary school， P．S.116． Here the gifted boy was first introduced to chess by a part﹣time teacher Makofsky， owner of a chess club． Interested in the game， the seven﹣year﹣old asked his mother to allow him to join the club． Not able to afford the chess classes， she emailed Makofsky． To her surprise and joy， Makofsky agreed that Tani could learn it for free．
Though the chess club helps， it's largely believed that Tani's success lies in his hard work． The boy practices the game for many hours a day on the floor with his board． Every Saturday， Tani goes to a free 3﹣hour class to improve his game skills．
Not surprisingly，Tani's story， first reported by The New York Times， has brought him great support from the American public． Soon after the young boy won the New York Championship， Makofsky began a GoFundMe activity for Tani and his family so that he could continue his chess journey． It raised ＄200，000 in just ten days， far more than they expected． And the money keeps coming． But the family donates （捐赠）most of the money to the church and to those poor families!
Tani has also received offers from three famous private schools in New York． However， the family have politely refused all of them and chosen to continue Tani's education at P．S.116．
The young boy's story also caught the eye of Bill Clinton，the 42nd US President． "Tani，you're an example of a winning spirit ﹣ in chess and in life． I'd love to meet you，" he said on his Facebook．
While excited about his new life，Tani is ready to meet great challenges （挑战）．He is busy preparing for the 2019 National Primary Championships． Winning the competition will bring the chess player closer to his dream of becoming the world's youngest chess grandmaster （大师）． The record has been kept for 17 years by the Russian chess player Karjakin， who won the title at the age of 12．

In the park，you see a group of people，all looking up at the sky． Without thinking about it， you look upwards， too． Why？ In the concert，someone begins to clap and suddenly the whole room joins in． You do， too． Why？
Sometimes we feel we are acting correctly when we do the same as others． The more people follow an idea， the better or truer we think the idea is． It's the social proof （社会认同感）that works．
The scientist Asch carried out an experiment． It shows how social proof can influence us． In a room， a man is shown Line 1，and next to it are three lines （A，B，C）． A is longer，C is shorter and B is as long as Line 1． He must tell which of the three lines is as long as Line 1． When the man is alone，he gives the correct answer B． Then， five other men enter the room， and each of them gives the answer C as they were told to． Now the man changes his idea and gives the answer C． Asch got the same result many times among different subjects （实验对象）．
Why do we act like this？Well，in the past， following others was a way to keep from danger．Suppose that 5000 years ago you were hunting （打猎） with friends．Suddenly，they all ran away．What would you have done？ Would you have stayed？ No，you would have run，too．We are descendants （后代） of those who copied others' action． It is so deeply planted in our mind that we still use it now．
Social proof has special power．The advertising industry，for example，often makes use of it．So be careful whenever a company says its product is "the most popular"．
