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.
Bui 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.The second paragraph is written to

As late as 1800, women’s only place was in the home. The idea of woman in the business world was unthinkable. Men were certain that no woman could do a good job outside her home. This was such a widely accepted idea that when the well-known Bronte sisters began writing books in 1864, they had to sign their books with men’s names instead.
Teaching was the first profession open to women soon after 1800. But even that was not an easy profession for women to enter because most schools and colleges were open only to men. Oberlin College i
n Ohio was the first college in America to accept women.
Hospital nursing became respectable work for women only after Nightingale became famous. Seeing that she was not only a nurse but also a rich and well-educated woman, people began to believe it was possible for women to nurse the sick and still be “ladies”. Miss Nightingale opened England’s first training school for nurse in 1860.
The invention of the typewriter in 1867 helped to bring women out of the home and into the business world. By 1900, thousands of women were working at 
real jobs in schools, hospitals and offices in both England and America. Some women even managed to become doctors or lawyers. The idea that women could work in the business world had been accepted. Why couldn’t women become teachers easily? Because___________

Hundreds of people lined up at Grand Central Terminal yesterday, but they weren’t there to catch a train. They came to New York City’s famous railroad station to trade in old dollar bills for the new George Washington Presidential $ 1 coin.
The gold-colored coin is the first in a new series by the U.S. Mint（造币厂）that honors former U.S. Presidents. The Mint will issue four Presidential $ 1 coins a year through 2016. Like the popular 50 State Quarters(纪念币) program, which issues coins in the order in which each state joined the Union, Presidential $ 1 coins will come out in the order in which each President served. The George Washington coin is the first to be release
d. John Adams, Thomas Jefferson and James Madison coins will come out later this year.
The Presidential $ 1 coins will be the same size and color as the Sacagawea Golden Dollar. However, there is an important difference. For the first time since the 1930s, there is an inscription（题字）on the edge of each coin. Each coin will show a different President on its face, or head side. It will also show the President’s name, the order in which he served and his years in office. The other side of the coin will show the Statue of Liberty and the inscriptions “United States of America” and “$ 1”.
There will be one Presidential $ 1 coin for each President, except Grover Cleveland. He will have two! Cleveland is the only U.S. Preside
nt to have served two nonconsecutive（不连续的）terms.
The last President scheduled to get a coin is Gerald Ford because a President must have been dead for two years before he can be on a coin. Hundreds of people lined up at the railway station in order to ____________.

can hold on to.”
Earlier in the day, at a news conference in Stockholm, Peter Englund, secretary of the Swedish Academy, said Ms. Müller was honored for her “very, very distinct special language” and because “she has really a story to tell about…and growing up as a stranger in your own family.we can learn from the passage that Ms. Muller is_______.

I first visited hutong as part of a tourist group several years ago. We rode on a trishaw（脚踏三轮车） with a guide explaining the history, architecture and lifestyle of the local inhabitants.
Having visited the "must-sees" of Beijing, like the Forbidden City, the Temple of Heaven, the Drum Tower and the Summer Palace, going into the hutong home of some famous ancient families gave the “Beijing experience” a human element.
My curiosity has sharpened over the years from reading about them at every opportunity. During the preparation for the Olympics I was eager to learn that some siheyuan courtyards in hutong were turned into accommodations（食宿） for visitors. I wished to stay in one someday.
Preparing for a recent trip to the capital, I eagerly sought one out. On my limited teacher’s salary, I settled on an affordable option, though I looked longingly at the more upscale courtyard accommodations.
As usual, I ended up having something closer to a true experience. A real family still lives in the courtyard, which is closer to the original. The rooms all opened into the central courtyard. Flowers were blooming, beans and peas were climbing up the bamboo fence, and the cat was napping in the sun. Every day after exploring the city, I'd hur
ry back to the hutong, take a quick shower and join the cat – snoozing（小睡） in a bamboo-made chair with a book ready nearby.
As the other guests came back we’d greet one another. There was a mother and young daughter from France, a guy from Canada, a mother and teenage daughter from the Netherlands, a teacher from England and several guests from various parts of China.
Coming and going through the narrow alleys（小巷） of the hutong, the residents would smile and give cheery “ni hao” （hello）. Laughing children were playing under the watchful eyes of the neighbors. I felt right at home in this friendly neighborhood. The main idea of the passage is about ______________.
| A．hutong days realize my desires to live local life |
| B．Trishaw is the only way to visit the hutong |
| C．living in the hutong with other visitors |
| D．exploring the deeper of Beijing |
When did the author have the idea to visit Beijing hutong?
| A．As early as he was a little child |
| B．when he was reading the text books at school |
| C．during the preparation for the Olympics |
| D．the author doesn’t mention it specifically |
The underlined word “upscale” in the fourth paragraph means _________.
| A．inexpensive | B．high-class | C．appropriate | D．secondary |
What is the impression of the author about the people in hutong?
| A．They came from all over the world. |
| B．They all wanted to enjoy the old life of Beijing. |
| C．They are living together in harmony. |
| D．They are living in a heavenly peace life. |
Once an Englishman named Larry Belmont went to Russia for a holiday. After he got back some of his friends came. “I had a very dangerous trip while I was in Russia.” Larry said, “I went to see a friend in the country and when the sun went down, I was still traveling through a forest in a sleigh(雪橇). It was a long way from my friend’s house when about twenty wolves began to follow my sleigh.”
“It was very dark in the forest. There was thick snow on the ground. First I heard the wolves. The noise was terrible! Then I saw long, grey forms among the trees, and soon the wolves were near me. They were running very fast, and they didn’t seem to get tired like the horses.”
“What did you do?” one of Larry’s friends asked.
“When the wolves got very near,” Larry answered, “I put up my gun and shot the first wolf dead. Then all the other wolves stopped and ate it, so my sleigh got away from them for a few minutes. Then they finished their meal, and I heard them coming again. The moon 
was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another one of them, and the others stopped once more to eat it. The same thing happened again, and my horses become more and more tired and ran slower and slower until, after two hours, only one wolf was still alive and following me.”
