【正文】 peratures are known to greatly reduce photosynthesis”可知，極度的高溫會減少光合作用。由第四段后面的內(nèi)容可知，令研究者們驚訝的是，面對著人工制造出來的熱浪，這些樹繼續(xù)以接近正常的水平蒸發(fā)，有效地使自己和周圍的環(huán)境涼爽下來。結(jié)合這兩點可以推知，面對人工制造出來的熱浪，光合作用應該是大大減少，但這并沒有影響樹木的蒸發(fā)。劃線部分意思應當接近于“大大減少，降低”這一類的意思cease意為“停止”，故選D。(4)考查推理判斷。根據(jù)倒數(shù)第二段中的“The researchers think the Parramatta red gums were able to effectively sweat — even without photosynthesis — because they are particularly good at tapping into water deep in the soil. But if a heat wave and a severe drought （干旱）were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.”可知，這些樹擅長吸取地下水，如果熱浪干旱同時發(fā)生，地下水枯竭的話，那么這些樹生存的可能性就比較小了。由此可以推知，地下水幫助這些樹存活下來。故選D。【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進行分析，推理，從而選出正確答案。7．閱讀理解 Mexico sites on an island plateau (高原) surrounded by volcanic peaks, which makes air quality a constant concern for people who live there. In April, the country took a decisive step toward improving air quality by enacting a temporary ban on private and Federal vehicles in the city. The rule forbids people from driving in the city one day each week and one Saturday each month. Electric vehicles, government service vehicles, public transport options and school buses are not included in the ban. Mexico City isn39。t the first urban center to be involved in carfree living. But the ban is more than an awarenessraiser. It was enacted with the direct aim of solving air pollution. In March, the city sank into a deep brown haze of smog when the pollution levels passed the 200 mark. The city ordered some of the area39。s cars off the streets and also offered free bus and subway rides. Mexico City39。s temporary vehicle ban raises questions about the best ways to improve urban air quality. India, whose citizens breathe some of the world39。s dirtiest air, has tried a variety of solutions. Earlier this year, the Indian government started a 4% sales tax on newcar purchases. Beijing also has experience with cleaning the air. The city introduced alternateday rules in advance of the 2008 Olympic Games, which produced good results. And then there is the London congestion (擁擠) charge, introduced in 2003. The charge has had a measurable effect on air quality.For now, Mexico City — named by the United Nations as the most polluted city on the planet in 1992 — can look forward to the start of the region39。s rainy season, when daily showers will help lo clean the air.（1）How did Mexico ban vehicles in the city?

George R. R. Martin writes each chapter from the perspective of a specific character, providing a limited point of view for each section. The reader is able to understand the inner workings of the individual, but the reader is barred from a whole understanding of the text. The world he has created has magic, but there is much more than that. While magic exists, it exists on the edge, and the inner unrest of the characters is much more important. His work also has a level of realness that is astonishing in a work of fantasy. Characters are imperfect, and many make questionable moral choices. In the end, however, Martin shows that both good and bad happen to both the people of high moral standard and the corrupt. He has made it clear that any character can die at any point, which has led to a lot of heartbreak from readers. In 2011, A Song of Ice and Fire became a television series titled Game of Thrones. Martin has been closely involved with the production. It has currently run for seven seasons, and viewers anxiously await the eighth season to answer their questions from the season seven finale. His fans are also waiting for The Winds of Winter and A Dream of Spring, the next books in the series, to answer the questions Martin and the television show have not yet addressed. Martin, however, has no plans to rush. He has made it clear that he will continue to write the books while working on the television show and writing other novels. But how will the story continue? What is going to happen in Westeros, and more importantly: when are we going to find out? Martinis skill as a writer has kept readers and viewers spellbound. Many hope he will finish the next book before the next season of the show begins, but
