(30分) 2023届高校毕业生迎来了秋招季，很多即将毕业的学生发现，大部分招聘岗位除了对专业、学历有要求外，还要求求职者有相关岗位的技能经验、工作经验。

面对现实，年轻大学生们似乎无心质疑这样的要求是否合理，而是扭头早早投入到了实习大潮中。

近期，媒体采访调查发现，越来越多的大学生早在大一大二的寒暑假尝试去各种行业、岗位实习，甚至还会“翘课”参加实习。

有学生表示，面对经济下行压力和疫情给就业市场带来的不确定性，他们提前感知到了来自考研、就业的竞争压力。

还有学生表示，将实习提前至大一大二，可以为准备考研、保研预留充分时间，也可以为求职、为寻找适合自己的职业发展方向提供帮助，这是他们的一条重要的“破局之路”。

Whethe r you’re the boss or the employee, whether your office is green already or still waiting to see the light, some practical steps can lay the groundwork for a healthy, low-impact workspace.1．More work, less energyFor many people, a computer is the central tool at work. Optimizing the energy settings for computers and other devices can be more than a modest energy saver. Set computers to energy-saving settings and make sure to shut them down when you leave for the day (“standby” settings will continue to draw power even when not in use). By plugging hardware into a power strip with an on/off switch (or a smart power strip), the whole desktop setup can be turned off at once (make sure to power down inkjet printers before killing the power—they need to seal theircartridges). Printers, scanners, and other peripherals that are only used occasionally can be unplugged until they’re needed. And of course, turn off lights in spaces that are un occupied.2．DigitizeIt does seem a bit strange that in the “digital age” we still consume enormous amounts of mashed up, bleached tree pulp, most of which gets used once or twice and then tossed or recycled (“downcycled,” as McDonough and Braungart would call it). The greenest paper is no paper at all, so keep things digital and dematerialized whenever possible. The more you do online, the less you need paper. Keep files on computers instead of in file cabinets (this also makes it easier to make offsite backup copies or take them with you when you move to a new office). Review documents onscreen rather than printing them out. Send emails instead of paper letters. New software like Greenprint helps eliminate blank pages from documents before printing and can also convert to PDF for paperless document sharing.3．Don’t be a paper pusherWhen buying printer paper, look for recycled paper with a high percentage of post-consumer content and the minimum of chlorine bleaching. Even recycled paper gobbles up a great deal of energy, water, and chemical resources in its processing (toxic pulp slurry is the paper recycling i ndustry’s dirty secret). When using the real stuff, print on both sides of the page when appropriate and use misprints as notepaper. Try to choose printers and photocopiers that do double-sided printing. If your office ships packages, reuse boxes and use shredded waste paper as packing material.4．Greening the commuteAmerican workers spend an average of 47 hours per year commuting through rush hour traffic. This adds up to 3.7 billion hours and 23 billion gallons of gas wasted in traffic each year. We can ease some of this strain by carpooling, taking public transit, biking, walking, or a creative combination thereof. If there’s no good way to phase out your car, consider getting a hybrid, electric vehicle, motorcycle, scooter, or using a car sharing service like Flexcar or Zipcar. See How to Green Your Car for more depth on the subject. Some employers are even giving a bonus to bike and carpool commuters and special perks to hybrid drivers. For those who think bike riding is for kids and tattooed couriers, consider a high-tech folding bike or an electrically assisted one (see below for more).5．Green sleevesYou might be amazed how sharp work clothes from thrift stores can look. If you buy new, get clothes made with organic or recycled fibers. Avoid clothes that need to be dry-cleaned, and if they so demand it, seek out your local "green" dry-cleaner. See How to Go Green: Wardrobe for more tactics on greening those work duds.6．Work from homeInstant messaging, video conferencing, and other innovative workflow tools make effective telecommuting a reality. If you can telecommute, hold phone conferences, take online classes, or otherwise work from home, give it a try. It'll save you the time you would have spent on the trip as well as sparing the air. As a bonus, you get to work in your pajamas. Telecommuting works for 44 million Americans (not to mention the TreeHugger staff). Also, consider the possibility of working four ten-hour days instead of five eight-hour days (a consolidated workweek), cutting the energy and time spent on commuting by 20% and giving you some lovely three-day weekends.7．Use Green MaterialsSome paper use can't be avoided, so use recycled paper and envelopes that have been processed and colored using eco-friendly methods. Pens and pencils can also be made of recycled materials, and refillable pens and markers are preferable to disposable ones. Use biodegradable soaps and recycled paper or cloth towels in the bathroom and kitchen, and provide biodegradable cleaners for the custodial staff. Buy in bulk so that shipping and packaging waste are reduced, and reuse the shipping boxes. Recycling printer cartridges is often free, and recycled replacements are cheaper than new ones.8．Redesign the WorkspaceGreening the space in which you work has almost limitless possibilities. Start with good furniture, good lighting, and good air. Furniture can be manufactured from recycled materials as well as recyclable. Herman-Miller and Steelcase are two groundbreaking companies that have adopted the Cradle-to-Cradle protocol for many of their office chairs. Incandescent bulbs can be replaced with compact fluorescents and there is an ever-growing selection of high-end LED desk lamps that use miniscule amounts of energy. Not only is natural daylight a free source of lighting for the office, it has been proven to improve worker productivity and satisfaction (as well as boost sales in retail settings). Workspace air quality is also crucial. Good ventilation and low-VOC paints and materials (such as furniture and carpet) will keep employees healthy (look for How to Green Your Furniture coming soon).9．Lunch timeBringing lunch to work in reusable containers is likely the greenest (and healthiest) way to eat at work. Getting delivery and takeout almost inevitably ends with a miniature mountain of packaging waste. But if you do order delivery, join coworkers in placing a large order (more efficient than many separate ones). Also, bring in a reusable plate, utensils, and napkins. If you do go out for lunch, try biking or walking instead of driving.10．Get others in on the actShare these tips with your colleagues. Ask your boss to purchase carbon offsets for corporate travel by car and plane. Arrange an office carpool or group bike commute. Trade shifts and job duties so that you can work four long days instead of five short ones. Ask the office manager to get fair trade coffee for the break room and make sure everyone has a small recycling bin so that recycling is just as easy as throwing paper away. Ask everyone to bring ina mug or glass from home and keep some handy for visitors so that you reduce or eliminate use of paper cups.26.To power off the electronic devices when they are not at work is a better way to save energythan a modest energy saver.27.According to the second suggestion, a green office had better substitute computer files forpaper files.28.In a green office, paper can be reused as file-paper or to be made into boxes for package.muters taking a ride to work will be awarded with a bonus.30.Clothes made with organic or recycled fibers usually do not require being dry-cleaned.31.If conditions permit, working at home by telecommuting can save you a day each week.32.Buying products in bulk can reduce packaging waste, but is a waste of energy if you don’treally need so many.33.Natural daylight is a free source of lighting for the office, besides that, it has been proven toimprove workspace air quality.34.The greenest way to eat at work is to bring lunch to work in reusable containers.35.To reduce or eliminate the use of paper cups, you can bring in a mug or glass from homeand keep some handy for visitors.Section B Reading in DepthDirections: There are 3 passages in this part. 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 onthe Answer Sheet with a single line through the center.Passage OneQuestions 36 to 40 are based on the following passage.Electronic books could revolutionize reading, but people ought to consider their far-reaching impacts as well. “The e-book promises to wreak a slow havoc(浩劫) on life as we know it,” Jason Ohler, professor of technology assessment(评估), university of Alaska Southeast in Juneau, warned the World Future Society, Bethesda, Md. His assessment weighed the pros and cons(赞成和反对的理由)of e-book technology’s impact on so cial relationships, the environment, the economy, etc. Before you curl up（蜷曲）with an e-book, consider the disadvantages.They increase eyestrain due to poor screen resolution, replace a relatively cheap commodity with a more expensive one, and displace workers in print book production and traditional publishing. E-books make it easy to share data, thereby threatening copyright agreements and reducing compensation of authors, as well as creating nonbiodegradable（不可生物降解）trash.On the other hand, e-books save paper and trees, reduce the burden of the carrying and storing of printed books, promote self-sufficiency in learning, and make reading a collaborative experience online. They also create new jobs for writers and artists and encourage self-publishing.In final analysis, Ohler points out, e-books should gain social approval if a few conditions are met: make them biodegradable and recyclable, solve the problem of eye fatigue (疲劳), besure the “have-nots” get the technology, and support e-book training in schools and business.36. What is the author’s purpose of writing the passage?A) Draw peoples attention to the disadvantages of e-books.B) Call on people to reject e-books.C) Criticize schools and business that don’t provide e-books.D) Encourage people to use e-books37. What is Jason Ohler’s attitude towards e-books?A) Positive B) Indifferent C) Cautious D) Suspicious38. In what sense do e-books exert a negative impact on the environment?A)They are unable to be broken down into harmless products.B) They consume a lot of natural resources.C) They produce harmful gases.D) They are capable of being reused.39. What is e-books negative impact on social relationships?.A) They create new jobs only for writers.B) Fewer and fewer people have access to new technology.C) They may threaten some traditional trades.D) They isolate people from one another.40. What does Ohler suggest regarding the use of e-books?A) The society should ensure the poor have access to the technology.B) The society should ban the use of e-books if they cannot reduce eye fatigue.C) The society should approve of the use of e-books if they are made recyclable.D) The schools should solve the present problems of e-books.Passage TwoQuestions 41 to 45 are based on the following passage.Before he left for Iraq, Shaun Blue never talked about the war with his friends. He didn't need to. "We all knew where each other stood," says Mike Bell, a fellow Marine who attended the University of Southern California with Blue. They were juniors when the war began. "All of us wanted to go. All of us wanted to be there."Blue had considered dropping out of college to enlist in the Marines rather than finishing school and entering as an officer. He was a voracious reader, a philosophy major whose interests ranged from hard sciences to Roman architecture. (His mother says he asked for a copy of Moby Dick as a Christmas present in second grade.) In college he was as serious about conditioning his body as he was his mind. He played pickup basketball in some of L.A.'s toughest neighborhoods. Once, late at night, after drinking beer with Bell, Blue told Bell he was going for a run. He donned a flak jacket for added weight and ran the darkened L.A. streets alone for hours, finally returning to the house shortly before dawn.Blue set off for his first deployment to Iraq on July 4, 2005. He joined the Marine campaign in Anbar province, leading a platoon in the Fallujah area. Even in the desert reaches of Iraq, Blue found ways to call Bell and his younger sister Amy Blue, who was living inIreland at the time. "Those phone calls from him were the highlights of my days," says Amy. "Hearing him across all those miles, it was like he was right there with me." He was killed halfway through a second tour in Anbar, while riding in the passenger seat of a humvee悍马（一种军用吉普车）that was hit by a roadside bomb. "Twenty-five years is so short," his sister says, "but I am very lucky that I could call him a brother and a true best friend for that long.""He wanted to fight," says Bell of his fallen friend. "He really, really did. He couldn't wait."41. Before joining the Iraq war, Blue was__________A) a junior school studentB) a classmate of BellC) the youngest son of the familyD) a third-year student at a university.42. The word “voracious” (Line 2,Para.2) in this passage most probably means ______.A) Tiring of new information and knowledgeB) Eating a large amounts of foodC) Wanting a lot of new information and knowledgeD) Being in deep thought43. Which of the following sentences was NOT true?A) Blue had a wide range of interestsB) Blue was fond of reading booksC) Blue had a sound mind and bodyD) Blue liked having beer and running in the dark street44. From the passage we can learn that the author’s attitude towards Blue’s death is_____.A) Sad but helplessB) Bitter but approvingC) Critical and disapprovingD) Depressed and regretful.45. All the students of the University at Southern California wanted to go to Iraq because_ ______.A) they were tired of the university life and wanted to go abroadB) they were all patriotic and wanted to do something for their own countryC) they thought Iraq was a disgusted country and needed to be punishedD) they wanted to devote their lives to the U.S.APassage ThreeQuestions 46 to 50 are based on the following passage.Space is a dangerous place, not only because of meteors(流星)but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food, which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft,if they are inside, do prevent a lot of radiation damage.Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed（畸形的）children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys; the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.46. According to the first paragraph, the atmosphere is essential to man in that ______.A) it protects him against the harmful rays from spaceB) it provides sufficient light for plant growthC) it supplies the heat necessary for human survivalD) it screens off the falling meteors47. We know from the passage that ________.A) exposure to even tiny amounts of radiation is fatalB) the effect of exposure to radiation is slow in comingC) radiation is avoidable in space explorationD) astronauts in spa cesuits needn’t worry about radiation damage48. The harm radiation has done to the Apollo crew members _______.A) is insignificant B)seems overestimatedC) is enormous D) remains unknown49. It can be inferred from the passage that ________.A) the Apollo mission was very successfulB) protection from space radiation is no easy jobC) astronauts will have deformed children or grandchildrenD) radiation is not a threat to well-protected space explorers50. The best title for this passage would be _______.A) The Atmosphere and Our EnvironmentB) Research on RadiationC) Effects of Space RadiationD) Importance Protection Against RadiationPart III Cloze (10%)Directions:There are 20 blanks in the following passage.
