(10 points)Weighing yourself regularly is a wonderful way to stay aware of any significant weight fluctuations. 1 , when done too often, this habit can sometimes hurt more than it 2 .As for me, weighing myself every day caused me to shift my focus from being generally healthy and physically active to focusing 3 on the scale. That was bad to my overall fitness goals. I had gained weight in the form of muscle mass, but thinking only of 4 the number on the scale, I altered my training program. That conflicted with how I needed to train to 5 my goals.I also found that weighing myself daily did not provide an accurate 6 of the hard work and progress I was making in the gym. It takes about three weeks to a month to notice any significant changes in your weight 7 altering your training program. The most 8 changes will be observed in skill level, strength and inches lost.For these 9 , I stopped weighing myself every day and switched to a bimonthly weighing schedule 10 . Since weight loss is not my goal, it is less important for me to 11 my weight each week. Weighing every other week allows me to observe and 12 any significant weight changes. That tells me whether I need to 13 my training program.I use my bimonthly weigh-in 14 to get information about my nutrition as well. If my training intensity remains the same, but Im constantly 15 and dropping weight, this is a 16 that I need to increase my daily caloric intake.The 17 to stop weighing myself every day has done wonders for my overall health, fitness and well-being. Im experiencing increased zeal for working out since I no longer carry the burden of a 18 morning weigh-in. Ive also experienced greater success in achieving my specific fitness goals, 19 Im training according to those goals, not the numbers on a scale.Rather than 20 over the scale, turn your focus to how you look, feel, how your clothes fit and your overall energy level.1.A.

(40 points)Text 1Unlike so-called basic emotions such as sadness, fear, and anger, guilt emerges a little later, in conjunction with a childs growing grasp of social and moral norms. Children arent born knowing how to say “Im sorry”; rather, they learn over time that such statements appease parents and friends and their own consciences. This is why researchers generally regard so-called moral guilt, in the right amount, to be a good thing.In the popular imagination, of course, guilt still gets a bad rap. It is deeply uncomfortable its the emotional equivalent of wearing a jacket weighted with stones. Yet this understanding is outdated. “There has been a kind of revival or a rethinking about what guilt is and what role guilt can serve,” says Amrisha Vaish, a psychology researcher at the University of Virginia, adding that this revival is part of a larger recognition that emotions arent binary feelings that may be advantageous in one context may be harmful in another. Jealousy and anger, for example, may have evolved to alert us to important inequalities. Too much happiness can be destructive.And guilt, by prompting us to think more deeply about our goodness, can encourage humans to make up for errors and fix relationships. Guilt, in other words, can help hold a cooperative species together. It is a kind of social glue.Viewed in this light, guilt is an opportunity. Work by Tina Malti, a psychology professor at the University of Toronto, suggests that guilt may compensate for an emotional deficiency. In a number of studies, Malti and others have shown that guilt and sympathy may represent different pathways to cooperation and sharing. Some kids who are low in sympathy may make up for that shortfall by experiencing more guilt, which can rein in their nastier impulses. And vice versa: High sympathy can substitute for low guilt.In a 2014 study, for example, Malti looked at 244 children. Using caregiver assessments and the childrens self-observations, she rated each childs overall sympathy level and his or her tendency to feel negative emotions after moral transgressions. Then the kids were handed chocolate coins, and given a chance to share them with an anonymous child. For the low-sympathy kids, how much they shared appeared to turn on how inclined they were to feel guilty. The guilt-prone ones shared more, even though they hadnt magically become more sympathetic to the other childs deprivation.“Thats good news,” Malti says. “We can be prosocial because we caused harm and we feel regret.”21.Researchers think that guilt can be a good thing because it may help _.A.foster a childs moral developmentB.regulate a childs basic emotionsC.improve a childs intellectual abilityD.intensify a childs positive feelings22.According to Paragraph 2, many people still consider guilt to be _.A.inexcusableB.deceptiveC.addictiveD.burdensome23.Vaish holds that the rethinking about guilt comes from an awareness that _.A.emotions are context-independentB.an emotion can play opposing rolesC.emotions are socially constructiveD.emotional stability can benefit health24.Malti and others have shown that cooperation and sharing _.A.may be the outcome of impulsive actsB.may help correct emotional deficienciesC.can bring about emotional satisfactionD.can result from either sympathy or guilt25.The word “transgressions” (Line 4, Para. 5) is closest in meaning to _.A.teachingsB.wrongdoingsC.discussionsD.restrictionsText 2Forests give us shade, quiet and one of the harder challenges in the fight against climate change. Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we are threatening their ability to do so. The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.Thankfully, there is a way out of this trap but it involves striking a subtle balance. Helping forests flourish as valuable “carbon sinks” long into the future may require reducing their capacity to absorb carbon now. California is leading the way, as it does on so many climate efforts, in figuring out the details.The states proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest. This temporarily lowers carbon-carrying capacity. But the remaining trees draw a greater share of the available moisture, so they grow and thrive, restoring the forests capacity to pull carbon from the air. Healthy trees are also better able to fend off insects. The landscape is rendered less easily burnable. Even in the event of a fire, fewer trees are consumed.The need for such planning is increasingly urgent. Already, since 2010, drought and insects have killed over 100 million trees in California, most of them in 2016 alone, and wildfires have burned hundreds of thousands of acres.California plans to treat 35,000 acres of forest a year by 2020, and 60,000 by 2030 financed from the proceeds of the states emissions-permit auctions. Thats only a small share of the total acreage that could benefit, about half a million acres in all, so it will be vital to prioritize areas at greatest risk of fire or drought.The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels. New research on transportation biofuels is already under way.State governments are well accustomed to managing forests, but traditionally theyve focused on wildlife, watersheds and opportunities for recreation. Only recently have they come to see the vital part forests will have to play in storing carbon. Californias plan, which is expected to be finalized by the governor next year, should serve as a model.26.By saying “one of the harder challenges,” the author implies that _.A.global climate change may get out of controlB.forests may become a potential threatC.people may misunderstand global warmingD.extreme weather conditions may arise27.To maintain forests as valuable “carbon sinks,” we may need to _.A.preserve the diversity of species in themB.lower their present carbon-absorbing capacityC.accelerate the growth of young treesD.strike a balance among different plants28.Californias Forest Carbon Plan endeavors to _.A.restore its forests quickly after wildfiresB.cultivate more drought-resistant treesC.find more effective ways to kill insectsD.reduce the density of some of its forests29.What is essential to Californias plan according to Paragraph 5?A.To obtain enough financial support.B.To carry it out before the year of 2020.C.To handle the areas in serious danger first.D.To perfect the emissions-permit auctions.30.The authors attitude to Californias plan can best be described as _.A.supportiveB.ambiguousC.tolerantD.cautiousText 3American farmers have been complaining of labor shortages for several years. The complaints are unlikely to stop without an overhaul of immigration rules for farm workers.Congress has obstructed efforts to create a more straightforward visa for agricultural workers that would let foreign workers stay longer in the U.S. and change jobs within the industry. If this doesnt change, American businesses, communities, and consumers will be the losers.Perhaps half of U.S. farm laborers are undocumented immigrants. As fewer such workers enter the country, the characteristics of the agricultural workforce are changing. Todays farm laborers, while still predominantly born in Mexico, are more likely to be settled rather than migrating and more likely to be married than single. Theyre also aging. At the start of this century, about one-third of crop workers were over the age of 35. Now more than half are. And picking crops is hard on older bodies. One oft-debated cure for this labor shortage remains as implausible as its been all along: Native U.S. workers wont be returning to the farm.Mechanization isnt the answer, either not yet, at least. Production of corn, cotton, rice, soybeans, and wheat has been largely mechanized, but many high-value, labor-intensive crops, such as strawberries, need labor. Even dairy farms, where robots do a small share of milking, have a long way to go before theyre automated.As a result, farms have grown increasingly reliant on temporary guest workers using the H-2A visa to fill the gaps in the workforce. Starting around 2012, requests for the visas rose sharply; from 2011 to 2016 the number of visas issued more than doubled.The H-2A visa has no numerical cap, unlike the H-2B visa for nonagricultural work, which is limited to 66,000 a year. Even so, employers complain they arent given all the workers they need. The process is cumbersome, expensive, and unreliable. One survey found that bureaucratic delays led the average H-2A worker to arrive on the job 22 days late. The shortage is compounded by federal immigration raids, which remove some workers and drive others underground.In a 2012 survey, 71 percent of tree-fruit growers and almost 80 percent of raisin and berry growers said they were short of labor. Some western farmers have responded by moving operations to Mexico. From 1998 to 2000, 14.5 percent of the fruit Americans consumed was imported. Little more than a decade later, the share of imports was 25.8 percent.In effect, the U.S. can import food or it can import the workers who pick it.31.What problem should be addressed according to the first two paragraphs?A.Decline of job opportunities in U.S. agriculture.B.Discrimination against foreign workers in the U.S.C.Biased laws in favor of some American businesses.D.Flaws in U.S. immigration rules for farm workers.32.One trouble with U.S. agricultural workforce is _.A.the aging of immigrant farm workersB.the rising number of illegal immigrantsC.the high mobility of crop workersD.the lack of experienced laborers33.What is the much-argued solution to the labor shortage in U.S. farming?A.To strengthen financial support for farmers.B.To attract younger laborers to farm work.C.To get native U.S. workers back to farming.D.To use more robots to grow high-value crops.34.Agricultural employers complain about the H-2A visa for its _.A.control of annual admissionsB.slow granting proceduresC.limit on duration of stayD.tightened requirements35.Which of the following could be the best title for this text?A.Manpower vs. Automation?B.U.S. Agriculture in Decline?C.Import Food or Labor?D.America Saved by Mexico?Text 4Arnold Schwarzenegger, Dia Mirza and Adrian Grenier have a message for you: Its easy to beat plastic. Theyre part of a bunch of celebrities starring in a new video for World Environment Day encouraging you, the consumer, to swap out your single-use plastic staples to combat the plastics crisis.The key messages that have been put together for World Environment Day do include a call for governments to enact legislation to curb single-use plastics. But the overarching message is directed at individuals.My concern with leaving it up to the individual, however, is our limited sense of what needs to be achieved. On their own, taking our own bags to the grocery store or quitting plastic straws, for example, will accomplish little and require very little of u
