13．A baby mermaid （美人魚） was just born in Finland； Justin Bieber is getting married； iPhone 6is going to be released this year…We read rumors every day on the Internet．With the help of social media，rumors-no matter whether they are true or false-spread like wildfire，and sometimes we can't be sure what to believe．
Now，an international group of researchers might be able to make it easier for us．They are working on a lie detector that could separate online truth from lies，Discovery News reported．
Named after the Greek goddess Pheme，famed for spreading bad rumors，the system is far from a traditional lie detector，which works by attaching a machine to a potential liar．Instead，Pheme analyzes the rumor directly．
When a rumor comes out，on a micro blog，for example，Pheme can trace the source of information to see if it was released by reliable sources like experts or news agencies．If it wasn't，Pheme then examines the history and background of the account to identify whether it was created just to spread rumors．
After finding the source of the rumor，the system can keep a close eye on how other users react to the rumor-either confirming or denying it-to help analyze and further determine the reliability of the information．
Some people might find the Pheme system unnecessary based on the idea that false rumors never survive for long and people always get to the truth over time．While that's a fair point，there is a certain class of rumors，such as"a tiger is at large"or"an asteroid （小行星） is about to hit the Earth"，that can cause panic among people and thus lead to serious consequences．
These are cases when we need to be able to check for accuracy quickly．"Our system aims to help with that，by tracking and verifying （查證） information in real time，"a leading researcher Kalina Bontcheva，at the University of Sheffield，UK，told the BBC．
According to Bontcheva，Pheme is still under development and won't be ready for another 18months．
Until then，there's an old-fashioned technique that you can use to protect yourself from false information-ask questions，check sources and don't believe any claim until you've seen the evidence．

63．What is the article mainly about？C
A．Tips on how to deal with rumors online．
B．Factors that make rumors so easy to spread．
C．A new device that can check whether online rumors are true or not．
D．An introduction to some types of lie detectors．
64．How does the Pheme system determine the reliability of a piece of information？B
A．Based on how the majority of people react to it．
B．Based on the reliability of its sources and the history of its authors．
C．By collecting and examining relevant information to further confirm it．
D．By making use of an"Internet bot"to track and verify the information．
65．Which of the following statements might the author agree with？D
A．The Pheme system is not very helpful because all rumors eventually die down．
B．The Pheme system will be ready to help social networks become more accurate by the end of．
C．The Pheme system can identify almost all kinds of rumors on social networking sites．
D．The Pheme system aims to respond to rumors quickly so as to reduce the impact of false ones．

1．In Los Angeles，drivers spend sixty-one hours every year stuck in traffic．These drivers know all too well how bad the traffic can be．"There're too many cars，and you can't move around a lot．"
Professor Cyrus Shahabi also knows about traffic jams．He lives more than 65 kilometers from his office at the University of Southern California，in Los Angeles．He is always late even with the help of a navigation （導(dǎo)航） system．
He decided to develop a program called ClearPath for that．He says his program uses historical data to predict traffic conditions even before the driver leaves the house．"What's unique is that we use a lot of data that's currently become available including traffic data，weather data，and we analyze that so that we can predict what's going to happen in front of you when you leave home．"
Professor Shahabi says his system does more than just respond to current traffic conditions．With ClearPath，he says，a driver can decide what time he wants to leave，and ClearPath will give the fastest route．It looks at the entire road network，including surface streets as well as highways，before the driver hits the road．Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities．
"I always thought that Los Angeles had the worst traffic，but now I know that Shanghai，Beijing，Seoul，Tokyo，believe it or not，Singapore，Hong Kong certainly are examples that can immediately use this．"
Professor Shahabi hopes to share this new technology with companies that already have navigation systems，such as Google and Apple．

18．Drunken driving-sometimes called America's socially accepted form of murder-has become a national epidemic （流行�。瓻very hour of every day about three Americans on average are killed by drunken drivers，adding up to an incredible 250，000 over the past ten years．
A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours．Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts，but the drunken killing has recently caused so many well-publicized tragedies，especially concerning young children，that public opinion is no longer so tolerant．
Twenty states have raised the legal drinking age to 21，reversing a trend （逆轉(zhuǎn)潮流） in the 1960s to reduce it to 18．After New Jersey lowered it to 18，the number of people killed by 18-20-year-old drivers more than doubled，so the state recently upped it back to 21．Reformers，however，fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes"about drinking and teach them to resist peer pressure to drink．
Though new laws have led to increased arrests and tests in many areas already，to a marked drop in accidents，some states are also punishing bars for serving customers too many drinks．A bar in Massachusetts was fined for serving six or more double brandies to a customer who was"obviously drunk"and later drove off the road，killing a nine-year-old boy．
As the accidents continue to occur daily in every state，some Americans are even beginning to speak well of the 13 years national ban of alcohol that began in 1919，which President Hoover called the"noble experiment"．They forgot that legal prohibition didn't stop drinking，but encouraged political corruption （腐�。� and organized crime．As with the booming drug trade generally，there is no easy solution．

31．What can be inferred from the fact of the traffic accidents in New Jersey？D
A．Young drivers were usually bad．
B．Drivers should not be allowed to drink．
C．Some drivers didn't surprise the legal drinking age．
D．The legal drinking age should be raised．
32．The underlined word"lenient"in the first paragraph meansC．
A．serious      
B．cruel           
C．merciful    
D．determined
33．Which of the following statements best shows the writer's opinion of drunken driving？A
A．It is difficult to solve this problem．
B．It may lead to organized crime．
C．The new laws can stop heavy drinking 
D．There should be no bars to serve drinks．
34．In America，the number of people killed by drunken drivers on average isC．
A.3 per day                    
B.250，000 over the last 10 years
C.72 each day                      
D．less than 500 each week
35．Drunken driving has become a major national problem becauseB．
A．drinking is America's socially accepted habit
B．most Americans drink quite a lot
C．not many people realized the severe subsequences caused by heavy drinking
D．publicity did not pay much attention to road accidents．
