百分之八十；分析如下,不妨设每份工作量为100,再根据题目给出条件求得原来abc队的工作效率为9：5：4,不妨再设他们相应的工作效率为9,5,4,则a队派出2/3人加入c队后,其工作效率变为9*（1-2/3）=3,5,4+（9-3）=10,所以a队和c队完成任务时分别还需要时间10/3和60/10,由于要使他们都完成,应取较大的时间即60/10=6,此时c队完成了6*5=30,再加上原来完成的任务的一半,所以他总共完成了（30+50）/100=80%

考点分析：
考点1：阅读表达
&阅读表达是阅读理解题的一部分,它是近年来出现的新题型,它要求学生在阅读文章后对文章中的某些内容或整篇文章做出概括,是一种读写结合题,所以大家在做这类题时首先要弄清完成的是什么任务,然后有的放矢地去阅读,最后进行归纳与总结. 一般任务型阅读的题型多为细节题,好的方法是先看问题,然后带着问题读文,把细节画出来,还有一种题型是归纳题,它又分两类.一类是段落性的,一类是概括中心内容(全文性)这种较难,不过是有方法的.都是要通读全文,至少3遍. &
任务型阅读理解题型的特征和一般解题方法 ： &
& &第一步：认真阅读试题背景，了解阅读材料的背景、话题或主题，确保解题时不脱离阅读的主题和正确思维的主线索。
& &第二步：仔细阅读题目，找出不同人物的不同要求，并在关键词下划线，以便有利于为第三步的的顺利解题创造良好的和必要的条件。 & & &第三：对照题目的要求，从A、B、C、D、E和F六个备选项中选出符合以上要求的对应条件。有时，我们只要顺着关键词的线索就能轻松找到正确的答案。例如，有一篇有关体育题材的任务型阅读理解的题目要求中涉及到姚明的NBA生涯，考生只要在备选项中找到”姚明”这个关键词,不用阅读整个题目和备选项就能轻松找到正确的答案。但是，在大多数情况下，还要从提出的若干备选项选择符合条件中的内容。同学们需要根据具体的情况灵活地选择解踢方式，跳读、扫读还是细读。在此，特别提醒各位同学：选项中肯定有一项是多余选项。 &第四步：快速对照“要求”和“条件”这一主要线索通读一遍，做到万无一失，提高答题的准确率，增强应试的信心。
& 阅读表达题步骤和技巧 &
& &1.认真审题，读懂题意。由于题目要求形式多样，在同一篇阅读材料中会要求完成不同的任务，因此解题前要先明确任务，做到心中有数。 & &2.快速阅读，掌握大意。在做题时要快速扫视一下文章的大意，然后结合前面的题目的要求，大致明白所要完成的任务。
& &3.细读题目，完成任务。在明白题意和文章意思的基础上，仔细阅读后面的题目要求，在原文中找出问题题干所包括的信息部分，这样就可以快速准确地抓住有效信息，确保答题的准确性。如果是根据英文释义写单词的题，则一定要确保所填的单词来源于原文，切不可脱离原文，随意发挥。
& &4.复读文章，核实任务。在初步完成所要求的任务以后，学生必须再仔细阅读所提供的短文，结合题意、文章和文后提供的任务信息、认真核实任务以保证答题正确。 &&
& &5．注意读写结合。任务型阅读不仅考查学生阅读理解层面的能力，更加注重考查学生“写”的能力。若是写单词，则要注意拼写正确，词形、词性有无变化，是否需要大写；若所要完成的是短语或句子成分，则需谨慎对待，依据所给题干分析要完成的是什么句子成分，需用什么样的表达方式，不可简单草率地将文中信息直接挪用。
& &总之，阅读理解不同于传统的阅读理解，它介于阅读理解与写作之间，教师应该适应新课改的要求，掌握阅读理解的特点，加强学生阅读能力的培养。

Do you want to know how and why a fall leaf changes color? We first have to understand what leaves are and what they do.Leaves are the world’s food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖), a kind of sugar. Plants use it as food for energy and growing.A chemical called “chlorophyll” in the leaves gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves.The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples, sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn. 1.Which should be in the box? A.air
