Unit 4 Global warmingⅠ.阅读理解(2017·会宁一中月考)Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.1．It can be concluded from paragraph 1 that ________.A．the problem of global warming will have been quite solved by 2020B．gas emissions have been effectively reduced in developed countriesC．the Paris Agreements is more influential than the Kyoto ProtocolD．humans have made continuous efforts to slow down global warming2．If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?A．The human population would increase by one third.B．Little over 50% of all species would still exist.C．Nations would not need to tighten their emissions targets.D．The Agreement's minimum goal would not be reached.3．If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be ________.A．0.8 ℃B．1.5 ℃C．2 ℃ D．3.5 ℃答案与解析本文介绍了人们一直努力减少温室气体的排放，并设立了到2100年我们应该达成的目标以及达成目标要符合的条件。

课时规范训练(二十九)Ⅰ.阅读理解AFor a long time the packaging industry has been attacked for using what is thought as large amounts of packaging, choosing materials which are felt to have high impacts on the environment, and for being responsible for littering and overflowing landfills. In a study performed by WRAP, one of the first to study food waste in the UK in 2012，the most frequent responses when consumers were asked about packaging were “uses too much material” and “bad for the environment”. The conclusio ns of these reports highlighted that the degree of the problem has been largely underestimated: at least 30% of food produced in the world is wasted. These figures are similar no matter if you are in the developed or developing world.However, two publ ications from cross­industry work groups were published recently, and have managed to reset the discussion to take into account the benefits of packaging for sustainability(可持续性). The first publication，“The Global Protocol on Packaging Sustainability”， describes an agreed common approach towards measuring packaging sustainability metrics(指标), so that the industry is not competing based on the definition of a metric, but rather competing based on performance. The second was, “Packaging in the Sustainability Agenda, A Guide for Corporate Decision Makers”，which highlighted the contributions of packaging to the three aspects of sustainability：packaging protects products and prevents waste (environmental aspect); packaging enables efficient business conduct (economic aspect); and packaging provides consumers with the benefits of the products it contains(social aspect)．Packaging performs indeed a wide variety of functions throughout the value chain and contributes to reducing food waste by protecting ingredients(佐料)and products during transportation and by delivering family­sized packages. Food waste could be avoided for single households if they are provided with the choice of pack sizes meeting their consumption patterns and are not forced to buy larger packs that they may not be able to finish before the use­by date. Despite the fact that smaller sized packs use more packaging，the fact that food waste is reduced would nevertheless decrease overall environmental impacts of the packed product.1．It has long been thought that ________.A．larger quantities of food are wasted in developed countriesB．WRAP is the first authority to study food waste in the UKC．packaging does great harm to the environmentD．packaging offers a powerful means to reduce food waste2．According to the two publications in Paragraph 2，________.A．an agreement should be reached on measuring packaging sustainabilityB．the industry should compete based on the definition of sustainability metricsC．smaller sized packs promote less packaging and purchase among consumers D．sustainable packaging is eco­friendly, economically practical and socially beneficial3．The author's attitude towards packaging is ________.A．approving B．negativeC．casual D．doubtful【语篇导读】本文介绍了包装对环境是有害的。

2018届人教版选修六一轮复习：Unit4Globalwarming单元学案设计（20页）2018届人教版选修六一轮复习：Unit4单元学案设计单元话题阅读What is Global Warming?The Earth as an ecosystem is changing, attributable in great part to the effects of globalization and man. More carbon dioxide is now in the atmosphere than has been in the past 650,000 years. This carbon stays in the atmosphere, acts like a warm blanket, and holds in the heat —hence the name …global warming.?The reason we exist on this planet is because the earth naturally traps just enough heat in the atmosphere to keep the temperature within a very narrow range - this creates the conditions that give us breathable air, clean water, and the weather we depend on to survive. Human beings have begun to tip that balance. We've overloaded the atmosphere with heat-trapping gasses from our cars and factories and power plants. If we don't start fixing the problem now, we?re in for devastating changes to our environment. We will experience extreme temperatures, rises in sea levels, and storms of unimaginable destructive fury. Recently, alarming events that are consistent with scientific predictions about the effects of climate change have become more and more commonplace.As the world heats up, the public simply goes coldIf you wanted to question whether global warming is indeed upon us, last week was not the time to do it. Two weeks before the official beginning of summer, a heat wave baked the eastern third of the U.S. and Canada, driving temperatures high into the 90s and even 100s. At the same time, a flurry of scientific paperswas released that seemed to explain all the late-spring suffering. In one study, French researchers reported that heat-trapping greenhouse gases are at their highest levels in 420,000 years. In another, U.S. scientists found that 57 species of butterfly may be altering their migratory patterns in response to changing heat patterns.In light of all this, a sweltering public must have been convinced at last that it's time to do something to cool off the overheated planet, right? Wrong. Even as the temperature was climbing, a new survey by the American Geophysical Union found that Americans are less concerned than ever about combatting global warming. "The more we talk about warming," says the study's director, John Immerwahr, "the [more the] public's concern goes down."Such an environmental disconnect may not be much of a mystery. Environmentalists complain that over the past two years industry groups have launched a coordinated advertising campaign to torpedo the 1997 Kyoto treaty, which requires industrial nations to reduce greenhouse emissions. More than $13 million has been spent on ads to block ratification of the treaty by the U.S. Senate. "The purpose of the ads was to convince most Americans that there isn't a problem or that it's too expensive to fix," says National Environmental Trust spokesman Peter Kelly.Environmentalists also criticize President Clinton for what they believe is his failure to press the issue. Only last week, Clinton moved for Kyoto treaty changes that environmental groups see as industry-pleasing loopholes. Says Daniel Weiss, the Sierra Club's political director: "Timid leaders communicate hopelessness." And hopelessness breeds indifference. If suchpopular so-whating persists, Immerwahr warns, the public may begin grasping at phony solutions to global warming. At the end of last week, some people took comfort from the report of a vast haze of pollutants that collects over the Indian Ocean in the winter, but that researchers only recently studied. Filthy as the cloud is, it does deflect solar radiation, and that could lead to cooling. But scientists warn that we cannot simply pollute our way out of global warming. The soot drops from the hazy atmosphere in weeks, whereas greenhouse gases remain for centuries.The way out of this gridlock, environmentalists say, is to show it's possible to reduce greenhouse gases without sinking the economy. Solutions include cleaner cars and better wind- and solar-power technologies. Says Greg Wetstone, program director for the Natural Resources Defense Council: "When these kinds of options become available, people will feel less hopeless." Of course, it's also possible that only when people feel less hopeless will they press their leaders to make the solutions available.注（1）：本文选自Time；06/21/99, p62, 3/4p, 2c。
