　　(2017·皖南八校第二次联考)

　　We sometimes think global warming or climate change is a problem very far away from our lives, and that only the government needs to worry about it. But it's hardly possible to completely stay out of it—scientists are now 95 percent sure that humans have been the “dominant cause” of global warming trends since the 1950s.

　　One of the conclusions of a report released on Sept 27 by the United Nations says that human activities have caused global temperatures to rise by 0.89℃ between 1901 and 2017. That might not seem like a lot, but the truth is that a major part of that heat has been absorbed into the oceans, which is not surprising given that they cover two thirds of Earth's surface. Also, water has a much greater capacity (容量) to absorb heat than the air does, according to The Economist.

　　While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life, humans' use of fossil fuels is the main source of excess (多余的) greenhouse gases. According to CNN, by driving cars, using electricity produced by burning coal and oil or heating our homes with coal or natural gas, we release a large amount of greenhouse gases into the atmosphere.

　　Your body can barely feel a difference of 0.89℃， but the Earth's ecosystems are so sensitive that even small changes can disturb them. It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct.

　　Global warming is also linked to an increase in extreme weather. A larger amount of carbon dioxide traps more energy inside the atmosphere. This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods. Worse still, melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year, according to The Guardian, which also increases the risk of flooding.

　　“The report should serve as another wake­up call that our activities today have a profound impact on society, not only for us, but for many generations to come，” French Michel Jarraud, secretary­general of the World Meteorological Organization, said at a news conference.

　　文章大意：全球变暖不是只有政府才关心的事，它与我们每个人都息息相关。

　　1．The underlined word “dominant” in the first paragraph means “ ________”．

　　A．common B．indirect

　　C．secondary

　　D．leading

　　答案：D　猜测词义题。画线词所在句意：现在科学家可以95%确定人类是20世纪50年代以来全球变暖的主要原因。所以画线词意为“主要的”。

　　2．Which of the following statements is TRUE according to the passage?

　　A．Greenhouse gases have been proven to harm merely the Earth.

　　B．There is little we can do to prevent global warming.

　　C．Global warming can increase the chances of droughts and floods.

　　D．The hugeness of oceans makes them better absorbers of heat than the air.

　　答案：C　细节理解题。由第五段第三句话“This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods.”可知，C项正确。

　　3．The rise in global temperatures between 1901 and 2017 ______.

　　A．is more harmful to smaller creatures than bigger ones

　　B．is not serious because most of the extra heat has been absorbed by the oceans

　　C．has made the Earth's ecosystems more sensitive to changes

　　D．is likely to cause many species to become extinct

　　答案：D　细节理解题。由第四段最后一句话“It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct.”可知，D项正确。

　　4．What is Michel Jarraud's attitude toward the report released by the UN?

　　A．Negative.

　　B．Supportive.

　　C．Doubtful.

　　D．Uninterested.

　　答案：B　推理判断题。由最后一段他所说的话“The report should serve as another wake­up call that our activities today have a profound impact on society, not only for us, but for many generations to come”可推知，他认为联合国的报告对我们有提醒作用，所以是支持该报告的。

　　(2017·南京市、盐城市二模)

　　Mark Twain said that “habit is habit, and not to be flung(扔) out the window by anyone, but coaxed(劝诱) downstairs a step at a time.” The chances of successfully changing negative behavior __1__

　　when you make gradual changes that give you time to

　　__2__

　　negative patterns for positive ones.

　　On any given day, countless numbers of us get out of bed and

　　__3__

　　to begin to change a given behavior “today”. Whether it be exercising more, drinking less, managing time

　　__4__

　　or some other change in a negative behavior, we start out with high

　　__5__. In a short time, however, a vast majority of people fail and are soon doing __6__ it was they thought they shouldn't be doing.

　　After considerable research, some researchers believe that behavior changes usually do not __7__ if they start with the change itself. __8__， they believe that we must

　　__9__

　　a series of “stages” to adequately prepare ourselves for that

　　__10__ change. Once you have analyzed all the factors that

　　__11__

　　what you do, you must decide which behavior­change technique will work best for you.

　　According to the psychologist Albert Ellis, most

　　__12__

　　problems and related behaviors arise from irrational(不理性的) statements that people make to

　　__13__

　　when events in their lives are different from what they would like them to be. For example, suppose after doing

　　__14__ on an exam, you say to yourself，“I can't believe I failed that easy exam. I'm so stupid.” By changing this irrational “catastrophic” self­talk into rational,

　　__15__

　　statements about what is really going on, you can increase the __16__ that positive behaviors will occur.

　　Positive self­talk might be

　　__17__

　　as follows: “I really didn't study enough for the exam. I just need to prepare for the next __18__.”

　　Such self­talk will help you to recover quickly from

　　__19__

　　and take positive steps to correct the situation. Some other technique like purposefully

　　__20__ or stopping negative thoughts and refusing to dwell on(沉湎于) negative images can also spare you wasted energy, time and emotional resources and move on to positive changes.

　　.语法填空

　　文章大意：本文是一篇情景对话，讨论了工厂污染环境的问题。

　　答案：

　　1．It/That　考查代词。此处指上句话提到的这家工厂严重污染空气，故可以填It/That，指代上文出现的名词。注意首字母要大写。

　　2．owners　考查名词。根据句子结构和句意可知，此处是“主人”的意思；同时根据题干中谓语动词“have promised”可知，应该用复数，故填owners。

　　3．a　考查冠词。根据句意可知，此处是表示“一种”的意思。故填a。

　　4．before　考查连词。根据题干结构可知，此处需要用连词来连接两句话，同时根据空格前后句意可知，所缺词意为“在……之前”。故填before。

　　5．harmful　考查形容词。根据题干结构可知，所填词应是形容词，故填harmful。be harmful to意为“对……有害”。

　　6．pouring　考查非谓语动词。根据题干中“with”可知，所填词在句中作宾补，而且与宾语之间是主动关系，强调动作正在发生。故填pouring。

　　7．has been polluted　考查动词的时态和语态。根据题干大意可知，此处指被动，而且强调对现在的影响。故填has been polluted。

　　8．but　考查连词。前后两句话之间是明显的转折关系。故填but，指他们总是承诺，但从不行动。

　　9．what/all　考查表语从句或定语从句。根据题干结构可知，本句话是一个表语从句，从句中缺少“need”的宾语，意为“……的东西”，故填what。同时what引导的名词性从句常可以转换为“all that”结构的定语从句。因为在本句中先行词在从句中作宾语，所以关系代词that可以省去。

　　10．right/correct　考查形容词。此处是表示同意对方所说的，意为“对的，正确的”，故填right/correct。
