10、ore than once. Each paragraph is marked with a letter. Answer the questions by making the corresponding letter on Answer Sheet 2.The History of the Lunch BoxA) It was made of shiny, bright pink plastic with a Little Mermaid sticker on the front, and I carried it with me nearly every single day. My l
11、unch box was one of my first prized possessions, a proud statement to everyone in my kindergarten:“l love Mermaid-Ariel on my lunch box.”B) That bulky container served me well through my first and second grades, until the live-action version of 101 Dalmatians hit theaters, and I needed the newest re
12、d plastic box with characters like Pongo and Perdita on the front. I know Im not alone hereI bet you loved your first lunchbox, too.C) Lunch boxes have been connecting kids to cartoons and TV shows and super-heroes for decades. But it wasnt always that way.Once upon a time,they werent even boxes. As
13、 schools have changed in the past century, the midday meal container has evolved right along with them.D) Lets start back at the beginning of the 20th centurythe beginning of the lunch box story, really. While there were neighborhood schools in cities and suburbs，one-room schoolhouses were common in
14、 rural areas. As grandparents have been saying for generations, kids would travel miles to school in the countryside (often on foot).E) “You had kids in rural areas who couldnt go home from school for lunch, so bringing your lunch wrapped in a cloth, in oiled paper,in a little wooden box or somethin
15、g like that was a very long-standing rural tradition,” says Paula Johnson, head of food history section at the Smithsonian National Museum of American History in Washington, D.C.F) City kids, on the other hand, went home for lunch and came back.Since they rarely carried a meal, the few metal lunch b
16、uckets on the market were mainly for tradesmen and factory workers.G) After World War ll, a bunch of changes reshaped schoolsand lunches.More women joined the workforce. Small schools consolidated into larger ones, meaning more students were farther away from home.And the National School Lunch Act i
17、n 1946 made cafeterias much more common. Still, there wasnt much of a market for lunch containersyet.Students who carried their lunch often did so in a re-purposed bucket or tin of some kind.H) And then everything changed in the year of 1950.You might as well call it the Year of the Lunch Box, thank
18、s in large part to a genius move by a Nashville-based manufacturer，Aladdin Industries.The company already made square metal meal containers, the kind workers carried, and some had started to show up in the hands of school kids.I) But these containers were really durable, lasting years on end. That w
19、as great for the consumer, not so much for the manufacturer. So executives at Aladdin hit on an idea that would harness the newfound popularity of television. They covered lunch boxes with striking red paint and added a picture of TV and radio cowboy Hopalong Cassidy on the front.J) The company sold
20、 600,000 units the first year. It was a major “Ah-ha!” moment, and a wave of other manufacturers jumped on board to capitalize on new TV shows and movies. “The Partridge Family, the Addams Family, the Six Million Dollar Man, the Bionic Womaneverything that was on television ended up on a lunch box,”
21、says Allen Woodall.Hes the founder of the Lunch Box Museum in Columbus, Georgia.“It was a great marketing tool because kids were taking that TV show to school with them, and then when they got home they had them captured back on TV,” he says.K) And yes, you read that right: There is a lunch box muse
22、um, right near the Chattahoochee River. Woodall has more than 2,000 items on display. His favorite? The Green Hornet lunch box, because he used to listen to the radio show back in the 1940s.L) The new trend was also a great example of planned obsolescence, that is, to design a product so that it wil
23、l soon become unfashionable or impossible to use and will need replacing. Kids would beg for a new lunch box every year to keep up with the newest characters, even if their old lunchbox was perfectly usable.M) The metal lunch box craze lasted until the mid-1980s,when plastic took over. Two theories
24、exist as to why. The firstand most likelyis that plastic had simply become cheaper. The second theorypossibly an urban mythis that concerned parents in several states proposed bans on metal lunch boxes,claiming kids were using them as “weapons” to hit one another. Theres a lot on the internet about
25、a state-wide ban in Florida, but a few days worth of digging by a historian at the Florida State Historical Society found no such legislation. Either way,the metal lunch box was out.N) The last few decades have brought a new lunch box revolution, of sorts. Plastic boxes changed to lined cloth sacks,
26、 and eventually,globalism brought tiffin containers from India and bento boxes from Japan. Even the old metal lunch boxes have regained popularity. “I dont think the heyday(鼎盛时期) has passed,” says D.J.Jayasekara, owner and founder of , a retailer in Pasadena, California. “I think it has evolved. The
27、 days of the ready-made, you stick it in a lunchbox and carry it to school are kind of done.”O) The introduction of backpacks changed the lunch box scene a bit, he adds. Once kids started carrying book bags，that bulky traditional lunch box was hard to fit inside.“But you cant just throw a sandwich i
28、n a backpack ,” Jayasekara says. “It still has to go into a container.”That is, in part,why smaller and softer containers have taken offthey fit into backpacks.P) And dont worrywhether its a plastic bento box or a cloth bag, lunch containers can still easily be covered with popular culture.“We keep
29、pace with the movie industries so we can predict which characters are going to be popular for the coming months,”Jayasekara says. “ You know, kids are kids.”36. Lunch containers were not necessary for school kids in cities.37.Putting TV characters on lunch boxes proved an effective marketing strateg
30、y.38.Smaller lunch boxes are preferred because they fit easily into backpacks.39.Lunch boxes have evolved along with the transformation of schools.40.Around the beginning of the nineteen fifties, some school kids started to use metal meal containers.41 . School kids are eager to get a new lunch box
31、every year to stay in fashion.42.Rural kids used to walk a long way to school in the old days.43.The author was proud of using a lunch box in her childhood.44.The most probable reason for the popularity of plastic lunch boxes is that they are less expensive.45.The durability of metal meal containers
32、 benefited consumers.Section CDirections: There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 wi
33、th a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.A growing number of U.S. bike riders are attracted to electric bikes for convenience, health benefits and their fun factor. Although ebikes first appeared in the 90s, cheaper options and longer-lasti
34、ng batteries are breathing new life into the concept.Established bike companies and startups are embracing ebikes to meet demand. About 34 million ebikes were sold worldwide last year, according to data from eCycleElectric Consultants. Most were sold in Europe and China,where the bikes already have
35、exploded in popularity.Recently, the U.s. market has grown to 263,000 bikes, a 25% gain from the prior year.The industry is benefiting from improved batteries as suppliers over the years developed technology for laptops, smartphones and electric cars. In 2004, the price of batteries used on ebikes f
36、ell, spurring European sales.But lower cost options are emerging, too. This month, three U.S. bikeshare companies, Motivate, LimeBike and Spin, announced electric bicycles will be added to their fleets. New York-based Jump Bikes is already operating an electric bikeshare in Washington，D.C.， and is l
37、aunching in San Francisco Thursday. Rides cost $ 2 for 30 minutes.The system works like existing dockless bikeshare systems,where riders unlock bikes through a smartphone app.“This is the beginning of a long-term shift away from regular pedal(踏板) to electric bikes,”said Jump Bikes CEO Ryan Rzepecki.
38、 “When people first jump on an ebike, their face lights up. Its exciting and joyful in a way that you dont get from a regular bike.”Two years ago, CEO Chris Cocalis of Pivot Cycles,which sells high-end mountain bikes,found that U.S. bike shops werent interested in stocking ebikes. Some retailers war
39、ned Cocalis that theyd drop the brand if it came out with an electric bike.Now that sales are taking off,the vast majority of bike dealers are asking Cocalis when hell make an ebike available. “Theres tremendous opportunity to get a generation of people for whom suffering isnt their thing,” Cocalis
40、said. “Ebike riders get the enjoyable part of cycling without themassive suffering of climbing huge hills.”46. What do we learn from the passage about ebikes?A) Their health benefits and fun values outweigh their cost.B) They did not catch public attention in the United States until the 1990s.C) The
41、y did not become popular until the emergence of improved batteries.D) Their widespread use is attributable to peoples environmental awareness.47. What brought about the boost in ebike sales in Europe at the beginning of the century?A) Updated technology of bike manufacture.B) The falling prices of e
42、bike batteries.C) Changed fashion in short-distance travel.D) The rising costs for making electric cars.48. What is the prospect of the bike industry according to Ryan Rzepecki?A) More will be invested in bike battery research.B) The sales of ebikes will increase.C) It will profit from ebike sharing
43、.D) It will make a difference in peoples daily lives.49. What prevented Chris Cocalis from developing ebikes sooner?A) Retailers refusal to deal in ebikes.B) High profits from conventional bikes.C) Usersconcern about risks of ebike riding.D) His focus on selling costly mountain bikes.50. What makes
44、Chris Cocalis believe there is a greater opportunity for ebike sales?A) The further lowering of ebike prices.B) The publics concern for their health.C) The increasing interest in mountain climbing.D) The younger generations pursuit of comfortable riding.Passage TwoQuestions 51 to 55 are based on the
45、 following passage.The terms “global warming” and “climate change” are used by many, seemingly interchangeably. But do they really mean the same thing?Scientists shaped the history of the terms while attempting to accurately describe how humans continue to alter the planet. Later, political strategi
46、sts adopted the terms to influence public opinion.In 1975，geochemist Wallace Broecker introduced the term “climate change” in an article published by Science. In 1979, a National Academy of Sciences report used the term “global warming” to define increases in the Earths average surface temperature,
47、while “climate change” more broadly referred to the numerous effects of this increase，such as sea-level rise and ocean acidification(酸化).During the following decades,some industrialists and politicians launched a campaign to sow doubt in the minds of the American public about the ability of fossil-f
48、uel use, deforestation and other human activities to influence the planets climate.Word use played a critical role in developing that doubt. For example,the language and polls expert Frank Luntz wrote a memo encouraging the use of “climate change” because the phrase sounded less scary than “global warming,” reported the Guardian.However, Luntzs recommendation wasnt necessary.A Google Ngram Viewer chart shows that by 1993 climate change was already more commonly used
