           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 pages and 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 400 African elephants from 1980 to 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 bow manystudents 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 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 20 kilometers. The 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 dawn, 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 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 l00 percent, 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 on month's expense, (See Graph 3 ).

    One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the art works.

    A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided the wife was doing all the talking. I admired his patience for putting up with her continuous talk. Distracted by their noise, I moved on.

    I met with them several times as I moved through the different rooms of art. Each time I heard her constant burst of words, I moved away quickly.

    I was standing at the counter of the museum gift shop making a purchase when the couple came near to the exit. Before they left, the man reached into his pocket and pulled out a white object. He extended it into a long stick and then tapped his way into the coatroom to get his wife's jacket.

    “He's a brave man.,” the clerk at the counter said, “Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise that his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show."

    “But what does he get out of the art?” I asked. “He can't see.”

    “Can't see? You're wrong. He sees a lot. More than you or I do,” the clerk said. “His wife describes each painting so he can see it in his head.”

    I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life. And I saw the love shared by two people as I watched this couple walk away.

    Japanese technology giant Toshiba has built a huge "clean" factory farm where it is growing various types of lettuce (莴苣) leaves without sunlight or soil for sale in its new healthcare business.

    Located in a disused 21,000­square­foot electronics factory in Yokosuka, Toshiba announces to have created a perfect "bacteria­free" environment where it will grow three million bags of lettuce a year.

    Completely cut off from conditions outside the temperature controlled tank, lettuce inspectors wear full body suits while making notes on the quality and growth of the leaves on their iPads in order to prevent the air around the plants becoming contaminated.

    Each plant is given man­made lighting to trick it into believing it is exposed to sunlight, while vitamin and nutrients are put directly into its roots, meaning the lettuce does not need soil.

    Toshiba's new high­tech farm may produce the world's highest quality lettuce. The final product will be free of any form of bacteria or insect life before being placed into sealed (密封的) bags, which should ensure the product has a longer shelf life than other lettuces.

    The gardening technique aims to have a bacteria amount of no more than 1/1000th­much lower than that found in normal gardening soil.

    Toshiba aims to harvest three million bags of leaf lettuce, baby leaf greens, cabbages and other kinds of vegetables every year­with each bag likely to cost people £1.

    The most important thing in organic vegetables, the lettuce requires no pesticides (杀虫剂) but is expected to have a similar shelf to plants that have been heavily treated with chemicals.

    The lettuce factory is no marketing trick by Toshiba, however. Instead it represents the company's latest attempt to expand its technology­led business.

    There are already plans for the technology giant to build similar factories around the world over the coming years and it will also be selling the high tech equipment that allows factories to produce similar products of exceptionally high quality.
