1、Week 4TuesdayTask 1：阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。(2015浙江，B)Graphs 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 c
2、an 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 tit
3、le，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 400 African elephants from 1980 to 2005)Captions usually summarize the authors main poin
4、t 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
5、 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 GraphsA bar graph has two axes and uses bars to show amounts.In Graph 1，we see that the xaxis shows grades that students earned，and the yaxis shows how many st
6、udents 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.There is a lot of information we can get from a simple graph like this (See Graph 1)Line GraphsA line graph looks similar to a bar graph，but instead of bars，it plots p
7、oints and connects them with a line.It has the same parts as a bar graphtwo labeled axesand can be read the same way.To read a line graph，its 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 somethi
8、ng 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 xaxis is days.The unit of measurement for the yaxis is kilometers.Thus we can see that，on the first day，the pipit flew 20 kilometers.T
9、he line segment goes up between Day 1 and Day 2，which means that the bird flew farther on Day 2.If the line segment angled down，as between Day 4 and 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 birds mi
10、gration.Pie GraphsA 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 100 percent，so each piece is a fraction of the whole.A pie graph might includ
11、e a legend，or it might use icons or labels within each slice.This pie graph shows one months expenses (See Graph 3)Food 25Movies 12Clothing 36Savings 20Books 7【语篇解读】本文介绍了图表的结构和用途，并举例加以说明。1When used in a graph，a legend is _Aa guide to the symbols and colorsBan introduction paragraphCthe main ideaDthe
