           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 ).

    When I was growing up，I was embarrassed to be seen with my father. He was badly crippled (跛脚)，and when we would walk together，his hand on my arm for balance，people would stare，I would be ashamed of the unwanted attention.

    It was difficult to walk together—and because of that，we didn't say much as we went along. But as we started out，he always said，“You set the pace. I will try to follow you.”

    Our usual walk was to or from the subway，which was how he got to work. He went to work sick，and even in bad weather. He almost never missed a day，and would make it to the office even if others could not. It was a matter of pride for him.

    When snow or ice was on the ground，it was impossible for him to walk，even with help. At such times my sister or I would pull him through the streets of Brooklyn，N.Y.，on a child's sleigh to the subway entrance. Once there，he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building，and he would not have to go outside again until we met him in Brooklyn on his way home.

    When I think of it now，I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.

    He never talked about himself as an object of pity，nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”，and if he found one，the owner was good enough for him.

    Now that I am older，I believe that is a proper standard by which to judge people，even though I still don't know exactly what a “good heart” is. But I know the times I don't have one myself.

    He has been away for many years now，but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did，I am sorry I never told him how sorry I was，how unworthy I was，how I regretted it. I think of him when I complain about my troubles，when I am envious of another's good fortune，when I don't have a “good heart”．

    A man, who sometimes takes my bus, is in rags. His life seems different from that of the others. He looks exhausted and carries nothing. He appears along a downtown street, seemingly out of nowhere. We sometimes want to know where he sleeps at night.

    A few weeks ago he boarded the bus. A few stops later, a young woman boarded. She swiped (刷) her bus-card, only to find the machine would not accept it. The driver told her to pay the $2.25 fare. “I just bought this card,” she said. “I paid the money...”

    The driver said she could take the card back to the sales office and explain the problem. In the meantime she would have to pay the fare for that day. The woman became confused and distressed. The rest of us just watched, wondering how the problem would be solved. Suddenly the man rose from his seat, dropped a few coins into the fare box.

    “You're lucky,” the bus driver said quietly. “He paid for you.” Silence fell over the bus. The rest of us had watched the woman's discomfort, but he felt it. We lawyers, journalists and business people headed downtown to help fix the world. He fixed her world.

    I haven't seen him since that day. Some people believe angels occasionally drop down and move among us. All I know is that I have a new respect for the simple act of kindness. It speeds us along on our way.

China Train Guide

    Quick Guide on China Train Travel

    If you're looking for an affordable and comfortable way to get around China, train travel is the way to go. Getting train information and cheap train tickets has never been easier. Online train ticket booking makes it easy for travelers to look through China's train timetable, compare train fares, and look for ticket availability. Once you've found a suitable train, you can book online and pick your tickets up at the train station or get them delivered to your home or hotel. Train tickets can be booked online a minimum of 35 minutes and a maximum of 60 days before departure.

    How to choose train types

    When you're buying China train tickets online, you'll notice that the journey duration differs depending on which type of train you choose. China train types can be recognized by their letter codes G, D and C trains are high-speed trains, while Z, T and K are slower or overnight trains. China's high-speed trains run between Chinese provincial capitals and first-tier Chinese cities. G trains (high-speed trains, standing for gāotiě) are China's bullet trains—the fastest trains with a maximum speed of 400 km／h. Tickets for these trains are the most expensive.

    How to buy train tickets

    Unless you can read Chinese, there are only two ways to make train reservations in China:

    —Online train ticket booking with a travel agency (up to 60 days before departure).

    —At the train station／local ticket agency with your passport (up to 58 days before departure).

    How to read train tickets

    When reading your train ticket, please take note of the Chinese characters and Pinyin printed next to your departure / arrival city. Directions (North, South, East, and West) appear in Pinyin (Bei, Nan, Dong, and Xi), not English. Please make sure you are going to the correct train station.

    Over the past few years I've had an uncomfortable sense that someone, or something, has been making changes to my brain. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Involving myself in a book or a lengthy article used to be easy. That's rarely the case any more.

    I think I know what's going on. For over a decade, I've been spending lots of time online. The Web has been a godsend to me as a writer. Research that once required days in the rooms of libraries can now be done in minutes by a few Google searches. Even when I'm not working, I'm scanning headlines or just tripping from link to link.

The Net is becoming a universal medium where information flows through my eyes and ears and into mind. The perfect recall of silicon memory (硅制存储器) can be a blessing to thinking. But that comes at a price. As the media theorist Marshall Mcluhan pointed out, media are not just passive channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is weakening my ability for concentration. Once I was a driver in the sea of words. Now I zip along the surface like a flying swallow.

I'm not the only one. When I mention my troubles with reading to acquaintances, Bruce Friedman, a blogger, also has described how the Internet has changed his mental habits. His thinking has taken on a "staccato (破碎)" quality. "I can't read War and Peace any more" he admitted, "I've lost the ability to do that."

A recently published study suggests that when reading online, we tend to become "more decoders (解码器) of information". We are not only what we read; we are how we read.
