ATips for waiting in lineWhen lining up at the supermarket checkout counter, the lines next to us always seem to be moving faster than the one that we are standing in.Now the New York Times has put together the research of scientists to give you some insights into the math and psychology of queuing. It also offered tips on picking the fastest line no matter if you’re lining up in a supermarket, a bank or anywhere else.Picking someone with a full chartUS mathematician Dan Meyer believes that a chart(购物车) full of items doesn’t tell the whole story. “Every person requires a fixed amount of time to say hello, pay, say goodbye and clear out of the lane,” he said. And that amount of time is an average of 41 seconds per person.On the other hand, the time that each item takes to be rung up is only three seconds. That means if there are five peopleahead of you, each with ten items in their charts, the waiting time will be 355seconds. But if there is only one person ahead of you ,with 50 items in the chart, the waiting time is 191 seconds. You do the math.Study the customerHow many people are ahead of you is one thing, and who they are is another. For example, if they are old people – and this is not ageist(年龄歧视的) – they tend to move slower and delay the checkout process.The items in their chart are also important. For example, four bottles of the same milk will definitely go faster than four completely different items.Choose a “serpentine line”In some places, there may be just one line leading to several checkout counters. The person at the head of the line goes to the next available counter. This is known as a “serpentine(蛇形的) line”. You should always choose a serpentine line because even if one of the cashiers or customers is slow, it won’t hold up an entire line.Go leftAccording to Robert Samuel, a US science writer, around 90 percent of people are right-handed, which means they tend to go to the right. So heading to the opposite direction – left –will give you a better chance of finding a faster line.21. If there are 6 people before you, and they buy 72 items altogether, then you have to waitabout ________seconds.A. 462B. 318C. 246D. 21622. What we needn’t consider before deciding which line to stand in?A. The number of people before you.B. The quantity of the goods to check out before you.C. What kind of people before you.D. How many left-handed people before you.23. We can learn from the passage that________.A. most people are used to choosing checkout counters on their rightB. we should always avoid lining up behind a crowded cartC. 7 cups of the same kind need as much time as 7 different ones to be checked outD. the cashiers and customers in a “serpentine line” are slowB"Selfie," taking a picture of yourself to post on social media, became an official word in the Oxford dictionary in 2013. The idea seems simple, just pose and snap a photo of yourself with your cell phone camera. How difficult could that be?But in 2014 a reported 15 people died while taking selfies. That number has risen each year since then. Thirty-nine deaths connected to selfies were reported in 2015. And, this year has seen more than 70 such deaths.Researchers from universities in the U.S. and India have released findings from the first study of deaths due to selfies. The investigators examined the causes and characteristics of the deaths.The researchers found that people who take selfies for sharing on social media often have a narcissistic tendency. The report says these people "use selfies as a form of self-identification and expression." They may take selfies in more dangerous settings because they seek greater attention.Thesedangerous situations can lead to injury, and even death. The researchers define a selfie death as "death of an individual or a group of people that could have been avoided had the individual(s) not been taking a selfie."One example of a dangerous selfie in the study involved bicycle races. People sometimes get on the track to take a picture of themselves with the racing bicycles behind them. Crashes and injuries have resulted. Another example described people standing on train tracks trying to get a selfie as a train moves toward them from behind. The most common cause of selfie death was falling from high places. It caused 32 of the 172 deaths during the last two and one-half years. Drowning was another common cause of death.And it might be more dangerous to be a man with a smartphone. Although women take more selfies, males were far more likely to die during selfies. 75.5% of the reported deaths were of men. About one-third of the 172 reported selfie deaths had a single death while 24 incidents involved the deaths of groups. Two of the incidents killed seven people each.24.What’s the passage mainly about?A. selfie deaths on the riseB. the danger of taking selfiesC. what a selfie death isD. the causes of selfie deaths25. What does the underlined phrase in Paragraph 4 probably refer to?A. A physical state.B. A psychological state .C. A difficulty.D.A camera.26.Which of the following is an example of selfie deaths?A. A man addicted to taking selfies died.B. A taxi-driver died with one of his passengers taking selfies.C. A man fell off the cliff while taking a selfie and died .D. An old lady died from heart attack when taking a selfie.27. From the passage, we can learn that________.A. selfie deaths are always single deathsB. women are more likely to die during selfiesC. it is dangerous to participate in bicycle racesD.selfie deaths happened in various waysCI worked lots of extra hours my first Christmas season as a saleslady for Dancer’s, the department store in my small hometown. I’d started the job, which paid 85 cents an hour, that summer of 1966 after getting a work permit at age 15. I soon learned how to fit shoes, measure and cut cloth, and keep the shelves of shirts and underwear nice and neat.We closed at 6 p.m. on Christmas Eve, and at 5:55 a local farmer came in to find gifts for his wife. I knew Mr. Johnson, whose daughter was in my class, so I went to help him. We wandered through the sweaters, dresses and skirts, and nightgowns(睡衣). We talked about size and color and what I thought Mrs. Johnson would like. After nearly an hour, Mr. Johnson decided on a nightgown with pretty pink slippers to match.By my third Christmas at Dancer’s, I was an experienced salesclerk. Mrs. Johnson had come into the store in late summer, and we visited while I helped her shop. As she commented on pretty colors and design, I made mental notes. When Mr. Johnson made his last-minute appearance on Christmas Eve, I was ready.I told him, “Mrs. Johnson was in not too long ago, and I noticed how much she liked this royal blue sweater. She’d also told me that she really needed new boots. I’d found some perfect boots in he r size and had put them aside for Christmas Eve. ” Mr.Johnson was impressed, and I think more than a little relieved. We completed the sale by 6:10 with everything wrapped in paper and ribbons!I worked for Dancer’s three more holiday seasons and was always there just before closing on Christmas Eve, when Mr. Johnson knew I had the answers he needed. Years later, I can well remember he once told me that the big stores in cities had more goods and lovely Christmas fantasies in their windowbut it’s only in a small town that neighbors take care of neighbors.28. What do we know about the author’s job in Dancer’s ?A. She enjoyed her work in Dancer’s .B. She worked long hours to get a good pay.C. It took her a long time to know what she should do.D. She could also help some customer make decisions.29. What did the author do before Mr. Johnson’s appearance on her third Christmas inDancer’s?A. She talked with his daughter.B. She kept his wife’s need and taste in mind.C. She kept an eye on his wife for quite a long time.D. She looked into the sales record of the store.30. What can be inferred from the passage?A.The author worked for Dancer’s for 5 years in all.B. Mr. Johnson doubted whether the author could help him.C. Mr. Johnson valued the sincere relationship in his neighborhood.D. Mr. Johnson didn’t believe the big stores in cities had what he wanted.31. What may be the best title for the text?A. My Working Experience in Dancer’sB. Mr. Johnson’s Christmas giftC. Last-minute Appearance on Christmas EveD. Christmas Gifts with neighbors’ considerationDA new ‘paparazzi-proof’ scarf has got heatedly welcomed since lanched. A new ‘paparazzi-proof’ scarf could be a game-changer for celebrities(名流) who prefer to shy away from the stage light. The ISHU scarf is the creation of Dutch-born fashion entrepreneur Saif Siddiqui and is designed to ‘give people their right to privacy back’. A host of celebrities including Cameron Diaz, singer Joe Jonas, Bayern Munich footballer Jerome Boateng and music producer Major Lazer have worn the ISHU after it was spotted at London Fashion Week last year.It works by reflecting the light back into a camera, effectively becoming ‘invisibility clothes’ for celebrities who don’t want their photo taken.Anyone wearing the scarf is protected from mobile flash photography, with the fashion accessory’s fabric effectively blocking out any unwanted pictures, although it doesn’t stop no-flash photographs from being taken.The 28-year-old Siddiqui was inspired while visiting family in Amsterdam in 2009 when his friends attempted to take a photo of him using an iPhone in front of some bikes.“He noticed that the bike’s reflector carried the flash of his mobile camera in a way that confused the faces of his friends in the picture,” th e ISHU website explains. “He immediately realized that if developed into the right product, this feature would be an ideal solution for his friends and is now available to the public who want to keep their private moments in public private. “Saif put together a team of experts who dug into the science of light and reflection, and how to blend technology with fashion.”He told Decoded Magazine: “The ISHU scarf effectively allows an individual to control what pictures and videos are taken of him. “There are n o more unwanted pictures and videos on Snapchat, Instagram, or Facebook! Everyone carries a phone with them nowadays that has an amazing camera. So, it all made sense to me.” More ISHU products are set to launch in August, with mobile phone cases set to launch in the next few weeks. The ISHU is currently sold out but you can pre-order it online for ￡289.32. Why did Saif design the ‘paparazzi-proof’ scarf?A. To help protect people’s privacy.B. To make a rich profit from the celebrities.C. Because the scarf is to get a heated welcome.D. To dig into the science of light and reflection.33. How did Saif get the creative idea of producing scarves?A. He was inspired by the photographs of bike.B. He was inspired when his friends attempted to take a photo of him.C. He was inspired when finding his friends’ picture was not ideal.D. He was inspired while cycling with his family members.34. Which of the following statement might be true?A. The paparazzi-proof scarf can prevent any unwanted pictures being taken.B. There might be fewer unwanted pictures and videos on internet.C. ISHU will be only used to effectively control pictures taken.D. Customers will mainly buy ISHU products online.35. Who might most need the ‘paparazzi-proof’ scarf?A. reporterB. fans.C. photographersD. singers第二节(共5小题，每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
