Several months ago, CCTV broadcast a documentary(记录片)film about criminals(罪犯). I remembered one criminal clearly: he had killed his girlfriend just because she wanted to leave him. The journalist asked him, “Do you regret killing your girlfriend？”
“No.”
“Why？”
“It's useless to regret，”the man answered calmly.
The journalist was silent. At that moment, I felt very angry. This man had made such an unforgivable mistake but he still wouldn't say he was sorry.
Is regret really useless?
Of course, regret is an emotion linked to the past and this feeling cannot turn back the clock. But I think people who say regret is useless ignore(忽视)two points. One is that regret is useful for the future and to one's soul. Look up the word“regret”in a dictionary: there are many expressions, such as“repent(悔悟)”，“chagrin(悔恨)”and so on. All these are used to tell people not to make similar mistakes after they have realized their fault. If you don't regret, how can you repent? On the other hand, for those such as murderers, who have already lost their future, regret is still a baptism(洗礼)for the soul. A murderer won't leave the world at peace with himself unless he understands what regret is.
I have no doubt that regret is a virtue. Just like a light in the darkness, it can offer people the ray of hope they need. No matter what you have done wrong, people will always respect you for showing regret and a willingness to correct your mistakes. In this way, regret is a special feeling. Correcting mistakes is better than complaining; it makes you feel good about yourself. So why not show some regret after doing something wrong?The writer felt very angry because of________.

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65% increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012.
The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”Which body part is most likely to get injured for a climber ?
| A．The arm | B．The knee |
| C．The ankle | D．The hand |
How many women climbers in American got injured while climbing a rock between 1991 and 2012 ？

I was born into a family of five children. As the youngest child, I didn’t have many new clothes. Though my parents worked very hard, we could hardly make ends meet. The only time we would receive new clothes was at Christmas.
The family across the street lived a much better life. They just had two daughters and they were often seen wearing new dresses. The younger girl named Anna was of my age. One afternoon, she walked on the street wearing a beautiful white dress. She looked like an angel in that dress. I, together with many little girls, followed her. We just couldn’t keep our eyes off her dress. We all wished we would have such a dress one day!
That day, after coming back, I told my mom that I wanted a dress like that. My mom frowned(皱眉) she thought such a beautiful dress like that must cost an arm and a leg, but my mom kept that in mind. She worked five days a week at that time, but when Christmas was getting close, she worked even on every Saturday.
However, several days before Christmas, I changed my mind. It was Anna’s birthday that day and I was invited to her home with some other girls. After that party, I asked if I could try on her white dress. “Of course,” she said, “and you can take it if you like it.” I couldn’t believe my ears. How could she give such a beautiful dress to someone else? After trying it on, I knew why.
The dress looked beautiful, but it was uncomfortable to wear. As a matter of fact, my back was quite itchy(痒的) after I put it on. From that day on, I stopped admiring what others had. They may not be as good aswe think.When the writer was a little girl, she .

For generations here in the deepest South, there had been a great taboo（禁忌）: publicly crossing the color line for love．Less than 45 years ago, marriage between blacks and whites was illegal, and it has been forbidden for much of the time since．
So when a great job about an hour’s drive north of the Gulf Coast attracted him, Jeffrey Norwood, a black college basketball coach, had reservations．He was in a serious relationship with a woman who was white and Asian．
“You’re thinking about a life in South Mississippi?” his father said in a skeptical voice, recalling days when a black man could face mortal（致命的） danger just being seen with a woman of another race, regardless of intentions．"Are you sure?"
But on visits to Hattiesburg, the younger Mr. Norwood said he liked what he saw: growing diversity．So he moved, married, and, with his wife, had a baby girl, who was counted on the last census（人口普查） as black, white and Asian．Taylor Rae Norwood, three, is one of thousands of mixed-race children who have made this state home to one of the nation's most rapidly expanding multiracial populations, up 70 percent between 2000 and 2010, according to new data from the Census Bureau．
In the first comprehensive accounting of multiracial Americans since statistics were first collected about them in 2000, reporting from the 2010 census, made public in recent days, shows that the nation’s mixed-race population is growing far more quickly than many researchers had estimated, particularly in the South and parts of the Midwest．That conclusion is based on the bureau’s analysis of 42 states; the data from the remaining eight states will be released soon．
In North Carolina, the mixed-race population doubled．In Georgia, it grew by more than 80 percent, and by nearly as much in Kentucky and Tennessee．In Indiana, Iowa and South Dakota, the multiracial population increased by about 70percent．
Census officials estimated the national multiracial growth rate was about 35 percent since2000 according to the known result, when seven million people ----- 2．4 percent of the population chose more than one race．If a black man married a white woman 50years ago, the worst result was that _____．
| A．he was sentenced to death |
| B．he was considered to be immoral |
| C．he was criticized by the public |
| D．he was treated as a lawbreaker |

| D．Mississippi has the largest multiracial population in the US． |
Which of the following states had the fastest growth rate of mixed-race population?

People in several American states may be surprised to see cars on city streets without a driver．Experimental driverless vehicles now are legal in Florida, Nevada and California．They are pointing the way to a future that is not far down the road．The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August．Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020．
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state．" Today we're looking at science fiction becoming tomorrow's reality-the driverless car．" The technology for these cars includes cameras, radar and motion sensors．The systems have been improved through competitions sponsored by the U．S．government agency DARPA．Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races．
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America．" A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes．" Other safety features include warning systems on the front and the sides of the cars．These systems help drivers , but don't replace them．Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers, you also remove most risks of an accident," Kendall said．He said consumers, however, may be unwilling to lose control．"It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first．"
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable．He said this will happen as the technology is improved．What can we learn from Paragraph l?
A．Driverless vehicles are now legal in the whole USA．
B．Volvo will be the first to sell driverless cars．
