Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever-increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to changing traffic conditions.
The online economics magazineForbes.comsays traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.
But scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers, planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders. reach an accident area faster.
The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.
About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.
The center shares its findings with firefighters, police. Transportation departments and the military. They also share information with universities and transportation company.The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.
Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.

While Jennifer was at home taking an online exam for her business law class, a monitor(监控器) a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked---remotely---to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was; Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honestly in the booming field of on line education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid---that students haven’t searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating become sharper in the last year with the growth of “open online courses.” Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check student’s identities using personas information, such as the telephone numbers they once used.
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating. Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To keep her from dishonest behaviors. |
| D．To prevent her from slowing down. |
The underlined expression cutting edge in Paragraph 3 is closest in meaning to _____.
| A．sharpening tool | B．advanced technique |
| C．effective rule | D．dividing line |
Some programs can find out possible cheaters by_________.
| A．checking the question answering speed |
| B．producing a large number of questions |
| C．scanning the Internet test questions |
| D．giving difficult test questions |
Buckingham Palace is where the Queen lives. It is the Queen’s official and main royal London home.Buckingham Palace was originally a splendid house built by the Duke(公爵) of Buckingham for his wife. George IV began changing it into a palace in 1826. It has been the official London home of Britain’s royal family since 1837.

I clearly remember the day when my little brother was born: January 1, 1994. One of my favorite family photos shows me lying with my mother in the hospital bed, happy but un-aware of the small, sleeping baby in the background.
I stayed with my grandparents for the weekend of my brother’s birth, excited about my new brother but not yet aware of what having a little brother would mean. I didn’t truly realize what was going on until we were in the hospital room at Duke University----
coincidentally (碰巧地), the same room in which I had been born two years earlier.
When I looked at my brother for the first time, I felt a mixture of fear and interest. Little did know that small, pink creature would grow up to be one of my favorite people in the world.
In reality, though I am two years older than my brother, I am more often than not the real baby in the family. I am very lacking when it comes to common sense. Instructions constantly confuse me and I frequently find myself totally puzzled by things like knowing how to start the washing machine or manage the storage settings on my iPhone.
That’s where Gibson comes in. The poor kid has had to guide me through more tasks than I would care to admit, but he never complains. Though I should probably be told to figure it out myself, he always comes through.
I’m envious of his ability to readily answer the ever-present, “What do you want to do with your life?” question at family gatherings. “Be a doctor,” he says----a solid answer, completely opposite to my shaky one, “Well, I’m an English major, so...”
My brother truly is my best friend. No one understands me better, and there isn’t anyone else I would want to be stuck with in our family. I may not have a clear idea of where I’m headed, but he is stuck with me.How did the author feel when he saw his brother for the first time?
| A．Angry and sad. |
| B．Excited and moved. |
| C．Curious and scared. |
| D．Happy and interested. |
What does the underlined sentence in the fourth paragraph mean?
| A．My brother is the real baby in the family. |
| B．In fact, I seem to be less mature than my little brother. |
| C．My brother gets more love from the family than I do. |
| D．I am growing more slowly than my brother. |
What does the brother often help the author do?
| A．Help him deal with many daily tasks. |
| B．Help him with his studies. |
| C．Give him advice on how to choose a major. |
| D．Comfort him when he is in a bad mood. |
What is the best title for this text?

Researchers at the University of Kansas say that people can accurately judge 90 percent of a stranger’s personality simply by looking at the person’s shoes.
“Shoes convey a thin but useful piece of information about their wearers,” the authors wrote in the new study published in the Journal of Research in Personality. “Shoes serve a practical purpose, and also serve as nonverbal(非语言的) indications with symbolic messages. People tend to pay attention to the shoes they and others wear.”
Medical Daily notes that the details detected in the study include a person’s general age, sex, income, political affiliation(派别), and other personality characteristics, including someone’s emotional stability.
Lead researcher Omri Gillath said the judgments were based on the style, cost, color, and condition of someone’s shoes. In the study, 63 University of Kansas students looked at pictures showing 208 different pairs of shoes worn by the study’s participants. Volunteers in the study were photographed in their most commonly worn shoes, and then filled out a personality questionnaire.
So, some of the results were expected: People with higher incomes most commonly wore expensive shoes, and flashier footwear was typically worn by extroverts(外向者).
However, some of the more specific results are interesting. For example, “practical and functional” shoes were generally worn by more “agreeable” people, while ankle boots went more closely with “aggressive” personalities.
The strangers of all may be that those who wore “uncomfortable looking” shoes tend to have “calm” personalities.
And if you have several pairs of new shoes or take exceptional care of them, you may suffer from “attachment anxiety”, spending a large amount of time worrying about what other people think of your appearance.
There was even a political calculation in the mix with more liberal types wearing “shabbier and less expensive” shoes.
The researchers noted that some people will choose shoe styles to mask their actual personality characteristics, but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing deep awareness into their personalities.According to Omri Gillath, a stranger’s personality can be judged by ___.
| A．he age and sex of the person |
| B．the personality questionnaire by the person |
| C．the emotional stability of the person |
| D．the shoes the person wears |
We can infer from Paragraph 2 that ___.
| A．a practical purpose is to wear shoes |
| B．people want to buy new shoes they pay attention to |
| C．shoes are vital to their wearers |
| D．the Journal of Research in Personality is a magazine |
The underlined word “agreeable” is closest in meaning to __.
| A．gentle | B．weak | C．generous | D．considerate |
Which might be the best title for the passage?
| A．Good Shoes, Good Character |
| B．Bad Shoes, Bad Personality |
| C．Shoes and Their Wearers’ Personality |
| D．Shoes Shape A Person’s Character |
