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 ).

    The African elephant, the largest land animal remaining on earth , is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原)surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat(栖息地).

    It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

    Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

    What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

    Who are we and what do we do?

    Since National Theatre Live was launched in June 2009, we've broadcast more than forty productions live, from both the National Theatre and other theatres in the UK.

    Our broadcasts have now been experienced by over 5.5 million people in over 2,000 venues around the world, including over 650 venues in the UK alone. Past broadcasts from the National Theatre have included Danny Boyles' Frankenstein with Benedict Cumberbatch and Jonny Lee Miller, War Horse; Man and Superman with Ralph Fiennes.

    Broadcasts from other UK theatres include Coriolanus from the Donmar Warehouse; Macbeth from the Manchester International Festival; Our biggest single broadcast to date is Hamlet with Benedict Cumberbatch at the Barbican, which has been seen by over 550,000 people.

    How do we do it?

    Though each broadcast is filmed in front of a live audience in the theatre, cameras are carefully positioned throughout the theatre to ensure that cinema audiences get the “best seat in the house” view of each production.

    Where can you find us?

    The nearest venue to you is Emei 1958 Cinema, located at No. 360 Qingjiang Road East, Chendu, China.

    What's on?

    Clicking “Book Now” will take you through to a third party site where you can complete your booking.

    A heated debate is currently going on in our town.Should we allow the cinema to be constructed in the Havenswood Shopping Center? There is just one large lot left to build on,and the theater would use up all of that space.Some people are excited at the idea of finally having our own movie theater.Others would rather travel ten miles to the nearest theater to keep our quiet town the way it is.They say it is enough to have Marvin's Movie Video Rentals.After all,Marvin's store keeps thousands of the latest videos.

    There are certainly benefits to renting videos.For one thing,you can plan your own schedule when it is convenient for you.You can relax on your sofa,and take a break whenever you need one.You can also talk to others without bothering any strangers seated nearby.In additional,it is a less expensive way to view a movie compared to going to a theater.

    On the other hand,seeing a movie in a theater is an experience all its own.First,you can see the movie on wide screen as the filmmaker intended.To be viewed on a television screen,a film must be changed in some way to make it smaller.One is the “pan-and-scan” method,which involves removing some of the details in the picture.The other way,called “letterboxing”,keeps the image the way it is on the big screen,with one annoying exception; because the big-screen version is wide,the same picture on a television screen must be long and narrow.

    Another problem is sound.The sound from a television cannot compare to the sound system in a theater.Your experience of a movie improves when you can clearly hear all of the sounds.Furthermore,at home,viewing companions often talk during a movie,which makes you miss out on what's happening in the film.

    Besides,having a movie theater will not mean that you can't still go to Marvin's! You will just have a choice that you didn't have before.Isn't it time for Havenswood residents to enjoy a little progress?

    When one of your car tires goes flat, there are two things you can do, you can complain and change it or, if you don't have a spare, stand helplessly beside the road and hope someone comes to your rescue. Now comes a third choice, called Quickwheel. It is designed to get disabled motorists rolling again as quickly as possible.

Quickwheel is basically a tiny emergency trailer—complete with three tough little wheels of its own-- that supports the flat tire and enables the motorists to drive to a service station without losing much time or expending much energy. The product is made in the US. Company, Quickwheel Inc. of Greenwich, Connecticut. According to the firm's president, Robert Bockweg, the product meets each of the major worries that customers relate with flat tires: safe, lost time and physical labor.

    To use it, motorists simply unfold the product to its fully extended position, set it in front of the disabled tire, drive the car onto the Quickwheel's ramp (斜板) and fix a special safety strap over the tire. The tire is then locked in Quickwheel's metal frame. Its three wheels do the rest of the work. According to Quickwheel Inc, its product can be driven “for miles” at the speed of up to 45 miles per hour “without any noticeable change in the vehicle's braking or steering operation”. The company also says that it can be used on just about any type of car, jeep, mini-van or trailer. (拖车)

    Bockweg says that Quickwheel will be sold first in the United States, at a price of 150 dollars. Sales agreements now being talked over should make the product ready for use in Japan, Canada and Western Europe in the near future.
