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 ).

    Your school asked parents about the social development in children in the last Parents' Meeting. Here are some opinions. Read the following information and answer the questions.

    The vast majority of people can buy pretty much anything they need. Not anything they want, necessarily, but anything they need to achieve a satisfactory degree of creature comfort: clothing, water, shoes and food.

    During my childhood, a Michael Pollan book would have been the prize of my year, were I to find it waiting under my Christmas tree or open it upon my birthday. I also used to be thrilled at receiving necessary things, like simple socks or gloves, as present. Nowadays I have too many gloves. I purchase leather gloves online that appear to be a good deal or just because I like their look.

    Prosperity (富足) is a good thing, right? Yes, of course. But for me, I find that the greater ease with which such a generous gift is purchased, the less significance it has when given. This is why I try harder at gifts.

    My first line of dealing with this problem is simply understanding the effect of a little time spent. Even writing out a thoughtful or funny card goes a lot further than a “cute top” purchased from a popular shopping website.

    Need help? Go to your printer. There's paper in there. Fold one sheet in half and draw a heart on the front. Open it up and fill the card with a poem or a few words of your own. Not only is it obvious that you took the time to select your words and write them down, but now you force the reader to stop for a short time and consider what you were trying to accomplish with them. The effort made by the two of you is the gift.

    No matter how you decide to spend a little more time on your giving, the point is just quite simply that you do. You don't have to give a person a handmade paper boat to get a reaction. But you won't be sorry if you do.

    Over the past few years, smart home tech has become more and more accessible and it's increasingly easy to find that you've bought a product that includes smart home features. So what does a modern smart home look like, and how can you start building one? You could get to start making your home smarter by the following gadgets.

    Large gatherings such as weddings and conferences can be socially stressful. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend going on with caution.

    The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. "It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual displays the person's name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.

    Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app they should know that there may be unintended consequences down the road with that information being used in another context that might come back to bite you."

    The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or "face blindness", a condition that prevents people from recognizing individuals they have met. To use this app a person first acquires an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

    When the weather's hot, do you enjoy a glass of Brad's Drink while watching your TV made by Tokyo Telecommunications Engineering, and surfing the web using a search engine called BackRub? No? Neither do I. That's because all these companies have changed their names.

    Brad's Drink is now Pepsi. The mouthful that was Tokyo Telecommunications Engineering has become, simply, Sony. And BackRub is now known as Google. Though I must admit, the idea of a back massage does sound good right now!

    Joking aside, choosing the right name for your start-up is a serious matter. Think of the case of a small Canadian company called Research in Motion, who in 1998 had just developed a high-tech mobile phone that could send emails.

    They were torn between names like MegaMail and ProMail. Then they sought the help of consulting firm Lexicon, who specialize in brand names. They had other ideas. They brainstormed words connected to enjoyment and freshness. Someone said.

    Lexicon's boss added two capital letters, and there you have it: BlackBerry was born. Since then it has sold over 33 million handsets to customers around the world. Would it have sold as well if it was called MegaMail? Who knows?

    Recently, BlackBerry sales have been overtaken by Android phones and Apple's iPhone. Lexicon's founder David Placek is a big fan of simple brand names like those Apple chooses: the iPhone. They l0ok a household word and by putting one letter in front of it, it ends up being game changing.

    So, for all you entrepreneurs(企业家)out there, make sure you allow time to develop a catchy and memorable name. Think about what makes your company different. What's your USP (独特的销售主张)? Maybe you can reflect that in your name.

    What about you? What would you call a company if you had one?
