9．Graph can be a very useful tool for conveying information，especially numbers，percentages，and other data．A graph gives the reader a picture to interpret．That can be a lot more efficient than pages and pages explaining the data．Graphs can seem frightening，but reading a graph is a lot like reading a story．The graph has a title，a main idea，and supporting details．You can use your active reading skills to analyze and understand graphs just like any other text．
Most graphs have a few basic parts：a caption or introduction paragraph，a title，a legend or key，and labeled axes．An active reader looks at each part of the graph before trying to interpret the data．Captions will usually tell you where the data came from （for example，a scientific study of 400African elephants from 1980to 2005）．Captions usually summarize the author's main point as well．The title is very important．It tells you the main idea of the graph by stating what kind of information is being shown．A legend，also called a key，is a guide to the symbols and colors used in the graph．Many graphs，including bar graphs and line graphs，have two axes that form a corner．Usually these axes are the left side and the bottom of the graph．Each axis will always have a label．The label tells you what each axis measures．
Bar Graphs
A bar graph has two axes and uses bars to show amounts．In Graph 1，we see that the x-axis shows grades that students earned，and the y-axis shows how many students earned each grade．You can see that 6students earned an A because the bar for A stretches up to 6on the vertical measurement．There is a lot of information we can get from a simple graph like this（See Graph 1）．
Line Graphs
A line graph looks similar to a bar graph，but instead of bars，it plots points and connects them with a line．It has the same parts as a bar graph-two labeled axes-and can be read the same way．To read a line graph，it's important to focus on the points of intersection rather than the line segments between the points．This type of graph is most commonly used to show how something changes over time．Here is a graph that charts how far a bird flies during the first five days of its spring migration （See Graph 2）．
The unit of measurement for the x-axis is days．The unit of measurement for the y-axis is kilometers．Thus we can see that，on the first day，the pipit flew 20kilometers．The line segment goes up between Day 1and Day 2，which means that the bird flew farther on Day 2．If the line segment angled down，as between Day 4and Day 5，it would mean that the bird flew fewer kilometers than the day before．This line graph is a quick，visual way to tell the reader about the bird's migration．
Pie Graphs
A typical pie graph looks like a circular pie．The circle is divided into sections，and each section represents a fraction of the data．The graph is commonly used to show percentages； the whole pie represents l00percent，so each piece is a fraction of the whole．
A pie graph might include a legend，or it might use icons or labels within each slice．This pie graph shows one month's expenses （See Graph 3 ）．

解答 24-27 ADCD
24．答案A．细节理解题．根据第三段可以得出答案，第三段出现了两次legend，第一次是在第一行a legend or key，第二次是在第六行A legend，also called a key，is a guide to the symbols and colors used in the graph．"一个图例，也被称为一个关键，是一个指导图中使用的符号和颜色．"而且答案直接可以在第六行找到，与答案选项表述一样a guide to the symbols and colors．
25．答案D．细节理解题．根据表述"In Graph 1，we see that the x-axis shows grades that students earned，and the y-axis shows bow many students earned each grade．You can see that 6 students earned an A because the bar for A stretches up to 6 on the vertical measurement．在图1中，我们看到X轴显示学生获得的等级，Y轴显示每个等级的学生数．可以看到，6的学生获得了A，因为在它延伸到6垂直测量．可以得出答案．另外其实不需要看文字说明，直接看图读图就可以得出答案．C以上就是包含A，B，C，其中A为6，B 为10，C为4，所以答案为20．
26．答案C．细节理解题．直接看图读图就可以得出答案．从曲线图可以得出答案是Day3．
27．答案D．细节理解题．直接看图读图就可以得出答案．从扇形图可以得出Clothing占比例最多．
点评 在解答事实细节题时，我们首先就要在试题中寻找关键的线索词，如名词、动词、形容词或副词等实义词，带着问题和它们去阅读短文，要标明其出处，为迅速、准确地选择正确的答案作好充分准备．其次要忠实于原文．该类题源于短文，所以在解题时要紧扣原文，在短文中找到相应出处，要以此为依据，而不是想当然地仅凭自己已有的知识进行答题．此外，还应注意句子间的逻辑关系（如因果、方位、次序、时间先后、转折/相对和递进关系）和认真识别指代词语（如代词和替代词：one，the one，those，that，it，they等）．
在解答询问出处和写作意图的题目时，就要能够理解文章的主旨大意（中心思想）：因为一篇文章通常是围绕一个中心展开的，所以只有通过阅读掌握该短文的主旨大意，才能正确理解短文，进而根据短文的事实、细节推断作者的观点和写作意图．要掌握短文主旨，可以通过寻找短文的主题句，而主题句通常在段首（最常见）、段中、段尾、段首和段尾或隐含在段落中．解答主旨大意的试题时常采用快速浏览法，只要先浏览文章的标题，首、尾段或每段的首、尾句，再重点寻找主题线索和主题信息即可．当然还要善于抓住文章的中心思想，把握住作者的观点和写作意图．
