阅读下列材料，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题纸上将该选项标号涂黑。

           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 ).

    What might the future be like? Here are some predictions: things to come, things to go.

    Spring Festival, the most important Chinese holiday when everyone returns home has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020.

    And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.

Newspapers will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.

    Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy.

    Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students ‘library, schoolbag and connection to the outside world. There will be robot teachers, who will check homework on computers and communicate with the students' parents through e-mail. And school buses will be like spaceships, comfortable and safe.

    America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while - then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet n friend. We may take days off to net as guides to our foreign friends. The Americans, however, express their welcome usually at homos, but truly can not manage the lime to do n great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, worm and real. We will find ourselves treated hospitably.

    For the Americans, it is often considered more friendly lo invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

    The Internet has opened up a whole new on-line world for us to meet, chat and go where we've never been before.

    But just as in face-to-face communication, there are some basic rules of behavior that should be followed when online. The basic rule is simple: treat others in the same way you would want to be treated. Imagine how you'd feel if you were in the other person's shoes.

    For anything you're about to send: ask yourself, "Would I say this to the person's face?" If the answer is no, rewrite and reread. Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face.

    If someone in the chat room is rude to you, your instinct is to fire back in the same manner. But try not to do so. You should either ignore the person, or use your chat software to block their messages. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate．When someone makes a mistake whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else.

    If you do decide to tell someone about a mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.

    It is not polite to ask others personal questions such as their age, sex, and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

Dogs are man's best friends—they are very good for children's health. Researchers found that family pets helped to protect babies against breathing problems and infections (感染).

    A team from Kuopio University Hospital in Finland studied 397 babies born at their hospital between September 2012 and May 2015 for their first year. They found that babies who lived with a dog or a cat spent fewer weeks with ear infections, coughs or runny noses. They were also less likely to need antibiotics (抗生素) than babies in homes without a pet.

    Study author, Dr. Eija Bergroth, said dogs brought dirt and bacteria (细菌) into the home, which helped children's immune system (免疫系统) to be strong. This improved their defenses against bacteria.

    As part of the study, parents filled out weekly diaries starting when the children were nine weeks old, recording information on babies' health as well as their contact with cats and dogs. They recorded if they had fever, ear infections, coughs or running noses. They also put down whether they needed antibiotics.

    Based on those diaries, the researchers found that about a third of the children spent most of their first year with a pet dog and 24 percent in a home with a cat. And children with no dog contact at home were healthy for 65 percent of the time, compared to between 72 and 76 percent for those who did have a pet.

    The researchers also found that contact with dogs, more than cats, was tied to fewer weeks of sickness for babies.

    However, the researchers said they couldn't rule out the possibility that people who own dogs are less likely to get sick for another reason, not due to any protection offered by pets.

Why do Chinese people love hot pot so much? As the winter months are coming in, more and more people are sitting around a table enjoying this kind of traditional meal. I find myself wondering what it is about this traditional meal, which has existed for more than 1, 000 years. What makes it a Chinese food favorite? It seems that the answer lies beyond the dish itself.

Hot pot isn't just designed to keep you warm during the cold months; it's also a social experience. It's a "theater" cooked food that turns a meal into an event. There is a lot of fun for everyone to have in adding some foods to the hot pot.

Hot pot is eaten over two to three hours. For this reason, it is often considered an evening's entertainment, and a time to spend with friends and families. However, many Westerners would be put off by the idea of other people sticking chopsticks in their food. When we come to eat at the table in the UK, we often have our own shares, although the experience is still a social one.

A similar experience to the hot pot can be found in Korean barbecue restaurants，which let you cook your own meat. This allows people to have their meat done however they want.

For most Westerners, the idea of going to a restaurant to cook their own food is very strange. But having a go, I find it's now one of my favorite meals in Beijing. The steam from the pot left my clothes smelling of food when I got home, but perhaps this was also part of the experience. When the cold wind is blowing outside, I am sitting around with my good friends, eating and drinking. For me it's like a dinner party where my taste buds (味蕾) and my appetite are equally satisfied in the warm company of friends.
