Amazingly, US crime figures have been falling for 20 years now. Of course, the big question is, why? And can any lessons be learnt?
One reason could be the fall in the demand for the drug crack. During the 1980s, drug-related crimes soared, mostly caused by desperate crack users. However, according to professor Blumstein, co-author of The Crime Drop in America, news of the dangers of crack use caused its decrease and led to a fall in the number of drug-related crimes.
Some say that the adoption of a zero-tolerance policy in many cities has helped lead to a fall in crime. In New York City, for example, mayor Rudy Giuliani imposed strict and automatic punishments for all crimes, including minor offences such as graffiti and littering. Many believe this has had a very strong deterrent effect.
Another reason could be smarter policing strategies. Anti-theft measures and educating the community about car theft has helped see a drop in crimes in many areas. Also, the use of crime mapping schemes that can discover identify crime peaks in different parts of the city has helped police target hotspots.
Another reason could be that more criminals are now behind bars. Sociologist John Conklin (from Tufts University) says a significant factor behind the fall in crime in the 1990s is the simple fact that many criminals are in jail. In his book Why Crime Rages Fell, he says sentencing was merciful in the 1960s and 1970s, when crime rose. But then more prisons were built and more offenders were imprisoned.
Some have linked the fall in violent crime to a decline in children’s exposure to lead in petrol. Jessica Wolpaw Reyes says, “Even low to moderate levels of exposure can lead to behavioral problems, reduced IQ, hyperactivity and youth crimes. You can link the decline in lead between 1975 and 1985 to a decline in violent crime 20 years later.”
Others say that the drop in crime has something to do with birth rates. According to statistics, birth rates peaked between 1957 and 1961, and the proportion of men in the US in their late teens and early 20s (the so-called “criminal age”) was highest in the late 70s and early 80s. However, as time went on, the proportion of people in this age group decreased.
Others claim that videogames have helped. A recent study has suggested that these games are keeping young people off the streets and therefore away from crime. Advocates of this argue that any effects the games may have in encouraging violent behavior is offset by the fact that the games keep potential criminals indoors and in front of the television.
Some argue that the widespread use of camera phones makes some criminals think twice before committing a crime and getting filmed doing it. Also, many believe that the mass use of CCTV has also had an effect.
Finally, some say that petty theft just isn’t worth it any more. The resale value of second-hand goods such as televisions, cameras or clothes is now so low (or even non-existent) that most people see no point in stealing.

Technology is making life easier for some dairy farmers. They use robotic systems to milk their cows. Cows are trained to follow a series of paths that lead to milking stations. Only one cow at a time can enter a station.
Once inside, the cow is rewarded with food. As the cow eats, a robotic arm cleans and connects the animal to the milking machine. A few minutes later, milking is complete. The gate is opened, the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day. The cows get to decide when they want to be milked. Cows are milked an average of about three times a day. Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system. A computer keeps records on their eating and milking. A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk. Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers. She means young people who are more interested in technology and less interested in working all the time on the farm. Still, she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm. Last year it became the fourth farm in southeast Minnesota to get a robotic milking system. A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars. The second cost 150 000.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot. He says the increase in milk production reaches a high of more than six kilograms per cow per day.From the first paragraph, we can infer________.
| A．the robotic system is designed to reduce labor |
| B．cows can be raised by robots in the future |
| C．robots direct cows into milking stations |
| D．cows are kept clean by robots on some farms |
Besides milking cows, the robotic system also can ________.
| A．adjust the temperature of milking stations |
| B．judge the quality of fresh milk |
| C．improve the appetite of cows |
| D．keep fresh milk for two weeks |
Why is the robotic system not popular now?
| A．Because young people have no interest in it. |
| B．Because it is difficult to learn how to use it. |
| C．Because people can’t afford to buy it. |
| D．Because it usually causes the waste of milk. |
According to Doug, what is the wage of an employee?
| A．150, 000-170, 000. | B．750, 000. | C．150, 000 -30, 000. | D．30, 000- 32, 000 |
The best title for the passage may be_______.
| A．Letting robot milk your cow | B．Milking cows by hand |
| C．Improving the quality of milk | D．Drinking fresh milk every day |
We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it’s an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.
Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.
The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.
When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.
In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.
Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce. It was _______ that discovered sugar could remove the bitter taste of cacao.
| A．The workers in the chocolate factory | B．The Spaniards |

April 27 is Take Our Daughters to Work Day in Britain. Started at first in the United States and brought to Britain in 1994, Take Our Daughters to Work Day has become a special day for girls between 11 and 15. On that day thousands of girls take a day off school and go together with one of their parents to their work places. The purpose of this day is to broaden girls' horizons（视野）and raise their self-confidence.
For many years people have thought that boys can do better than girls in society. But actually, “girls can be whatever they want to be just like boys, whether it is a pilot, a nurse or a chief executive(主管).”says the chairman of the Our Sons and Daughters Charitable Trust, an organization which supported the activity of the Day. “Now the girls have a close look at what their parents are doing and this may help them to be more self-confident when they are faced with a choice of work."
Schools and many companies support the activity too. Palmers Green High School for girls in north of London, has made the day a necessary part of careers education.
Zarina Bart, 15, from Palmers Green, went with her mother Gwen to her Lawyer's office this year's Take Our Daughters to Work Day. "I learned how to fill in a legal aid form and I read details of a case. Then I went to see the actual trial." she said.
Zarina found it interesting to see her mother at work. “It's really strange seeing Mum at work--running around, getting serious and telling people what to do.” She has always liked this idea of going into law and thinks it likely that she will follow in her mother’s footsteps. Having a chance to see how her mother works has given her more self-confidence.
Experts believe that girls with higher self-confidence aim higher and are more likely to be successful in life. Parents have important effect on the confidence of teenage girls. If parents believe in their daughters and show examples both at work as well as at home for them, this will give a lot of help to girls. Take Our Daughters to Work Day is surely a step in the right direction.The writer’s purpose in writing this text is to ______.

Technology has totally transformed our ability to communicate with each other. Linking to each other both literally and figuratively, many of us connect through cell phones, email, instant messaging, blogs, and networking web sites, yet we may be less connected to each other than we think.
According to a study, Americans are becoming increasingly socially isolated(孤立的). The study suggests, for example, that one quarter of Americans say that they have no one to discuss important personal issues with, and that the number of close friends that Americans have has dropped from three to two. Meanwhile, the Boston Globe reports that this spreading isolation is experienced more sharply among those with less education, people of color, and older Americans. Unsurprisingly, those who are young, white, and well educated tend to have stronger social networks.
From my own experience I have to say that I’ve never felt more connected, thanks to a web of friends, family, and colleagues. One of my closest friends is someone I met through an online discussion group who lives hundreds of miles away from me. We have met face-to-face only twice, yet our regular electronic correspondence and cell phone calls maintain our close friendship. And, speaking of blogging, my blog has introduced me to people I would never have met otherwise and has led to enduring and important friendships.
On the other hand, I recently saw a scene unfold that proved to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy (治疗) center.
As I was leaving, I noticed a mother and her teenage son who had just completed their session with their family therapist. After making their next appointment, they both took out their cell phones, placed calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their cars, and, as I saw them drive off, they were still talking on their cell phones but not to each other.What does the passage lead you to believe?
| A．Americans are more socially isolated today. |
