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 many students 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 ).

Dear Hamilton,
We are fortunate that in such a large, high-pressure office we all get along so well. You are one of the people who keep the social temperature at such a comfortable setting. I don’t know anyone in the office who is better liked than you.
You can perhaps help with this. The collection of contributions towards gifts for employees’ personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral（葬礼）remembrance, four birthday gifts, and three graduation gifts.
It’s not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don’t know them outside the office, who wouldn’t even recognize their graduating children, their marrying daughters and sons, or their dead relatives.
This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today’s office setting.
Thank you for understanding.The underlined word “contributions” probably means ________.
| A．money | B．suggestions | C．reports | D．understanding |
Hamilton is expected to _______.
| A．show more kindness. | B．discontinue the present practice |
| C．quit being the organizer for gift giving | D．know more about co-workers’ families |
This is basically a letter of ________.
| A．apology | B．sympathy | C．appreciation | D．dissatisfaction |

Domestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.
Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.
As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.
Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (矿井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.
The domestication of horses has had great effects on societies. For example, horse were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new from of rapid transportation helped cultures spread around the world.Before domestication horses were ______.
| A．caught for sports | B．hunted for food |
| C．made to pull ploughs | D．used to carry people |
The author uses the Shetland horse as an example to show ______.
| A．it is smaller than the Clydesdale horse | B．horse used to have gentle personalities |
| C．some horses have better shaped than others | |
| D．horses were of less variety before domestication |
Horses contributed to the spread of culture by ______.
| A．carrying heavy loads | B．changing farming methods |
| C．serving as a means of transport | D．advancing agriculture in different areas |
The passage is mainly about _______.
| A．why humans domesticated horses | B．how humans and horses needed each other |
| C．why horses came in different shapes and sizes | |
| D．how human societies and horses influenced each other |

Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger at 2:30 AM. When I arrived to collect, I found the building was dark except for a single light in a ground floor window.
I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.
After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.
I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.
She kept thanking me for my kindness. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”
“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”
“It’s not the shortest way,” I answered quickly.
“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”
I quietly reached over and shut off the meter(计价器).
For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl.
Sometimes she’d ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing.
At dawn, she suddenly said,” I’m tired. Let’s go now.”
We drove in silence to the address she had given me.
“How much do I owe you?” she asked.
“Nothing.” I said.
“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.
Almost without thinking, I bent and gave her a hug. She held onto e tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”The old woman chose to ride through the city in order to ______.
| A．show she was familiar with the city | B．see some places for the last time |
| C．let the driver earn more money | D．reach the destination on time |
The taxi driver did not charge the old woman because he ______.
| A．wanted to do her a favor | B．shut off the meter by mistake |
| C．had received her payment in advance | D．was in a hurry to take other passengers |
What can we learn from the story?
| A．Giving is always a pleasure. | B．People should respect each other. |
| C．An act of kindness can bring people great joy. | |
| D．People should learn to appreciate others’ concern. |
Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part －drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.Watchers doubted if any of the vehicles could finish the race because .
| A．they did not have any human guidance |
| B．the road was not familiar to the drivers |
| C．the distance was too long for the vehicles |
| D．the prize money was unattractive to the drivers |
DARPA organized the race in order to .
| A．raise money for producing more robotic vehicles |
| B．push the development of vehicle industry |
| C．train more people to drive in the desert |
| D．improve the vehicles for future wars |
From the passage we know “robotic vehicles” are a kind of machines that .
| A．can do effortlessly whatever tasks living thing can |
| B．can take part in a race across 142 miles with a time limit |
| C．can show off their ability to turn themselves upside down |
| D．can move from place to place without being driven by human beings |
In the race, the greatest distance one robotic vehicle covered was .
| A．about eight miles | B．six miles |
| C．almost two miles | D．about one mile |
In the last paragraph, the writer implies that there is a long way to go .
| A．for a robotic vehicle to finish a 142-mile race without any difficulties |
| B．for a little child who has just learned to walk to reach the cookie on the table |
| C．for a robotic vehicle to deal with a simple problem that a little child can solve |
| D．for a little child to understand the importance of wiping apple juice off its face |
MONTREAL (Reuters) – Crossing the US-Canada border（边界）to go to church on a Sunday cost a US citizen ＄10,000 for breaking Washington’s strict new security（安全）rules.
The expensive trip to church was a surprise for Richard Albert, who lives right on the Canadian border. Like the other half-dozen people of Township 15, crossing the border is a daily occurrence for Albert. The nearby Quebec village of St. Pamphile is where they shop, eat and go to church.
There are many such situations in these areas along the largely unguarded 5,530-mile border between Canada and the US-which in some cases actually runs down the middle of streets or through buildings.
As a result, Albert says he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada, as usual. The US customs（海关）station in this area is closed on Sundays, so be just drove around the locked gate, as he had done every weekend since the gate appeared last May, following a tightening of border security. Two days later. Albert was told to go to the customs office, where an officer told him be had been caught on carnera crossing the border illegally（非法）.
Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country when Canadian customs stations are closed, but the US stopped a similar program last May. That forces the people to a 200-mile detour along hilly roads to get home through another border checkpoint.
Albert has requested that the customs office change their decisions on the fine, but he has not attended a Sunday church since. “I feel like I’m living in a prison,” he said.We learn from the text that Richard Albert is .
| A．an American living in Township 15 | B．a Canadian living in a Quebec village |
| C．a Canadian working in a customs station | D．an American working in a Canadian church |
Albert was fined because he .
| A．failed to obey traffic rules | B．broke the American security rules |
| C．worked in St. Pamphile without a pass | D．damaged the gate of the customs office |
The underlined word “detour” in paragraph 5 means .
| A．a drive through the town | B．a race across the fields |
| C．a roundabout way of travelling | D．a journey in the mountain area |
What would be the best title for the text?
| A．A Cross-country Trip | B．A Special Border Pass |
| C．An Unguarded Border | D．An Expensive Church Visit |
