soil, soak(渗透) up extra water and take carbon dioxide out of the atmosphere.However, it now turns out that planting trees could add to global warming.We all know that tree roots do a great job of keeping soil firmly on the ground and out of the winds power.The problem is that some of the dust clouds play an important part in soaking up carbon dioxide.Huge dust storms blow out over the oceans from dry parts of North Africa and Central Asia.Tons of dust are lifted and left as a thin film over the ocean surface.Dust from China is carried east and left in the Pacific Ocean.If a treeplanting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.Andy, an environmental scientist has spent the past few years studying dust and says his work shows clearly the complexity of the system.For this reason the need is to focus on cutting carbon dioxide giving off rather than doing anything else.Robert, an American scientist, has shown that when native grassland areas are invaded by trees, carbon is lost from the soil.“We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grass, so less carbon goes directly into the soil from trees.” said Robert.In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.Countries that plan to fight against global warming by planting trees may have to think again.Solutions to environmental problems are often more complex than they first appear, and understanding the Earths climate is a very great challenge.36People usually hold the opinion that_.Ahuge dust storms can destroy carbon dioxideBplanting trees could reduce global warmingChuge dust storms can destroy the oceans on the EarthDplanting trees is the only way to control huge dust storms37Andy, an environmental scientist, believes that_.Aenvironmental problems are more complex than expectedBtrees shouldnt have been planted in dry placesCdust plays a more important part than treesDcarbon dioxide is harmful to everything38Roberts experiment proves that_.Atrees absorb more carbon than grassBcarbon can turn grass into dustCless carbon can make trees grow fasterDgrassland areas should be covered by forests39The best title for this passage is “_”AThe importance of planting treesBThe dust clouds soak up carbon dioxideCIs it really useful to plant trees to reduce global warming?DWhy the soil carbon disappears答案课时作业(二十九).1.A考查短语辨析。句意：我丈夫今晚因故不能前来，我代表他向你们致谢。on behalf of意为“代表”；stand for是动词短语，不符合句子结构要求。C、D意思不符。2C考查动词短语辨析。句意：孩子们在家的时候我们不得不忍受一些噪音。这里考查put up with “忍受；容忍”。go in for “从事”，hold on to “坚持”和keep up with “跟上”不合题意。3A考查衔接词。句意：我的朋友玛丽生病了，是一种很奇怪的发烧，结果，她不能吃也睡不着。这里的as a resultas a consequence表示一种结果。4A考查名词辨析。句意：如果批量购物会比较便宜，但是在购买前要注意商品的质量。quantity意为“数量”，而quality意为“质量”，短语in quantity意为“大量的”。5B考查状语从句。句意：_下雨我也去明天的展览会。根据句意可知，上下文是让步关系，所以用even if，意为“即使”。as if as though 意为“好像”；as soon as意为“一就”。6A考查名词辨析。coal, oil, gas都是fuels(燃料)。article意为“商品”；goods意为“货物”；product意为“产品”。 7D考查非谓语动词。句意：别淋雨。带把伞以防下雨。这里考查的是get done表示某种遭遇。8B考查动词辨析。句意：现代家具设计越来越简单，我们生活中的很多东西都是如此。tend to意为“倾向于”； attend to意为“照顾” ，add to意为“增加”， appeal意为“吸引”，都不合题意。9C考查动词辨析。句意：温度是在15度到35度之间变化。range fromto意为“在范围内变化”；spread意为“传播”，move意为“移动”和shift意为“转换”，均不合题意。10D考查动词短语辨析。句意：这场音乐会下周四举行，届时我们将欣赏到最好的钢琴家的最好的表演。这里的take place 意为“举行”。11C考查固定短语。make a commitment意为“作出承诺”。句意：我儿子承诺期末考试得个A。wonder意为“奇迹”；duty意为“职责”；task意为“任务”。12A考查动词短语辨析。句意：他们关注世界的健康，并且他们强烈地_战争。根据语意可知，此处应为“反对”，所以用be opposed to。13C考查名词辨析。circumstance 意为“情形，情况”，表明与某事件或某人有关的情况、环境、境况等。under no circumstances意为“在任何情况下都不”。condition 意为“条件”；environment 意为“环境”；surrounding常用复数形式，指“环境，周围的事物”。14A考查动词辨析。句意：政府出版的那本书陈述了妇女的权利与责任。这里state意为“陈述”。15B考查动词辨析。句意：“新法案通过了吗”。“当然，只有少数人反对。”agree意为“同意，赞成”；oppose意为“反对”；support意为“支撑，扶持，支持”；approve意为“批准，通过”。根据句意法案通过，是反对的人少，所以选B项。.俗话说“贪小便宜吃大亏”，在生活中诚信显得很重要。本文通过描述Mr Glen的一段亲身经历说明了这一道理。16Aset up设立，成立；come up走近，出现；go up上升，增长；call up召唤，使想起。由语境可知选A。句意：他成立了他的小公司。17C根据全文可知，Mr Glen把这次教训当做交了一次“额外的”学费。extra额外的，不包括在价目表内的。文章最后一段中because the additional high “school” fee也有暗示。18B根据前文decided to return to the homeland可知，此处表示“离开”。19C空格后的made through years of work after school and the scholarships 可知，他用他的积蓄(课外工作所得和奖学金)买的。saving存款，积蓄。20Ctake down拿下，摘下；put down放下，镇压；lie down躺下；look down俯视。此处的意思是“手表也要摘下来进行检查”。故选C。21C根据后文中nearly￥100,000可排除A和B，从had to pay the tax可知，携带“特定的”物品出境需要缴税。22Bit代指前面的the tax。23D根据后文中carrying fake and shoddy(劣质的)goods可知。24Bbe proud of以自豪。他以为自己的小聪明会得逞，正洋洋自得。25Ain the presence of Glen“当着Glen的面”。26D非限制性定语从句的引导词which指代the watch，cost的主语为物，spend的主语为人。27A根据Glen was amazed可知答案。他还没有明白过来是怎么回事，就被带到了办公室。28D根据后文“他知道只有黑名单上的人才享受这种特殊待遇，工作人员仔细检查了他的箱子”可以判断，应选D。29B此处指根据多次出入境的经历，他知道30A“在时间”应用“what time”。工作人员警告他无论什么时候出入境，他都必须接受检查。31B这是一个省略的虚拟语气句。If(he were)found out reusing and carrying fake and shoddy(劣质的)goods, he would be charged according to law! find out查明(真相)。32Dboard the plane登机。33D固定短语make a deep impression on表示“对留下深刻的印象”。34A根据前文故事可知，他的经历让他懂得了诚信的重要性。35A他将永远牢记诚信他成功的秘密。.人们通常都认为植树可以减少空气中的二氧化碳，然而，新的发现证明植树反倒会助长全球变暖。36B推理判断题。从第一段的第二句“然而，现在证明植树可能会助长全球变暖”和最后一段第一句可推断出，人们通常所持的观点是“植树可能会减缓全球变暖”。37A细节理解题。由第四段第一句中的says his work shows clearly the complexity of the system可知，这位环保专家认为环境问题比人们估计的更要复杂。38A细节理解题。根据第五段内容可知，这位美国科学家通过研究发现，当树侵占了草坪的地方时，碳元素就从土壤中消失，分析其原因得知，与草相比，树在成长的过程中需要大量的碳，所以从树木那里直接进入到土壤里的碳就比从草里进入到土壤里的要少，即树比草吸收的碳要多。39C主旨大意题。全文通过实例证明植树可能会助长全球变暖，所以C项最能突出主题，其他三项只是文章内容的一个部分或某部分中的一个事实。111
