New crime prediction software should reduce not only the murder rate, but the rate of other crimes. Developed by Richard Berk, a professor at the University of Pennsylvania, the software has already used in Baltimore and Philadelphia to predict which individuals on probation(缓刑) or parole(假释) are most likely to murder and to be murdered.
“When a person goes on probation or parole he is supervised(监督) by an officer. The question is ‘what level of supervision is appropriate?’” said Berk. It used to be that parole officers used the person’s criminal record, and their judgment to make decisions.
“This research replaces those seat-of-the –pants calculations,” he said.
Technology helps determine level of supervision. On average there is one murder for every 100,000 people. Even among high-risk groups the murder rate is one in 100. Predicting such a rare event is very difficult, but advances in computer technology works.
Years ago, the researchers made a dataset of more than 60,000 various crimes. Using the software they developed, they found some much more likely to commit murder when paroled or probated. They could identify eight future murderers out of 100.
Berk’s software examines roughly two dozen variables(可变因素), from criminal record to geographic location. The type of crimes, and more importantly, the age at which that crime was committed, were two of the most predictive variables.
“People assume that if someone murdered then they will murder in the future,” said Berk. “ What really matters is what that person did as a young individual. Predicting future crimes sounds well. But we aren’t anywhere near being able to do that.”
“Berk’s scientific answer leaves policymakers with difficult questions. By labeling one group of people as high risk, and supervise them closely, there should be fewer murders, which the potential victims should be happy about. It also means that those high-risk individuals will be supervised more aggressively. For human rights advocates, that means punishing people who, most likely, will not commit a crime in the future,” said Bushway. “It comes down to a question of whether you would rather make these errors or those errors.”The underlined words(in Para.3) probably mean___.

The term “Industry 4.0” refers to the fourth industrial revolution. The first industrial revolution was the production of goods with machines like steam engines, which was followed by the second industrial revolution that introduced mass production with the help of electric power, followed by the digital revolution —the use of electronics and IT in production.
Industry 4.0 is a high-tech project, which promotes the computerization of manufacturing (制造业). The basic principle of Industry 4.0 is that by connecting machines, work pieces and systems, we are creating intelligent networks along the entire value chain that can control each other automatically. The goal is the Smart Factory, which adapts well and uses resources efficiently as well as linking customers and business partners with great intelligence. Technological basis are the Internet systems and advanced factories. Experts believe that Industry 4.0 could be a reality in about 10 to 20 years.
So, what effects does this change have on the classic manufacturing? According to an expert, “it is highly likely that the world of production will become more and more networked until everything is connected with everything else.” Networks and processes have so far been limited to one factory. But in the time of Industry 4.0, the boundaries (界限) of individual factories will most likely no longer exist. Instead, they will be lifted in order to inter-connect multiple factories or even geographical regions.
How is an Industry 4.0 factory different from a today’s factory? In current industry environment, providing high-end quality service or product with the least cost is the key to success. Factories are trying to increase their profit as much as possible. In the time of Industry 4.0, various data sources are available to provide worthwhile information about different aspects of the factory. Using data for understanding the current condition and checking faults and failures is a natural thing. The sharing of information around the clock and around the globe will enable these connected systems to manage themselves independently, work more efficiently and identify any errors quickly.
The good news is that Europe is much better prepared for the Industry 4.0 revolution than one might think. Europe will position itself as a pioneer in the fourth revolution. Industry 4.0 is a project in the high-tech strategy of the German government. Meanwhile, in the U.S., some companies are also working hard on it. But the success of industry depends on whether business and politics can work together. It’s not only politics that needs to help open the door for Industry 4.0. Every company is advised to seize the new digital opportunities.What marks the coming of Industry 4.0?
| A．Steam engines. | B．Mass production. |
| C．Use of electronics. | D．Intelligent networks. |
Industry 4.0 will probably result in ________ in the world of manufacturing.
| A．production limited to an individual factory |
| B．everything connected with everything else |
| C．networks and processes no longer existing |
| D．classic factories stopping their competition |
What’s the meaning of the underlined part in Para. 4?
| A．Sharing information of the world time. |
| B．Global news broadcast at any time. |
| C．Instant worldwide information exchange. |
| D．Spreading news widely on the hour. |
According to the last paragraph, who is the most active in pushing Industry 4.0?
| A．The European companies. |
| B．The American government. |
| C．The American companies. |
| D．The German government. |
The current Ebola (埃博拉病毒) outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus —about 60 percent of people infected with it have died.
How is Ebola doing its harm?
When a person becomes infected with Ebola, the virus damages the body’s immune (免疫的) cells, which defend against infection, said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack, then he is more likely to survive the disease.
The patients that survive it best are those who dont get such a bad disadvantage in immune system. But if the body isnt able to get rid of this attack, then the immune system becomes less able to regulate (调节) itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death.
What are the common symptoms of the disease?
Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.
How to prevent the spread of Ebola?
Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.
We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.
Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you’re around infected patients.
How Do People Survive Ebola?
Doctors don’t know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection.
Our suggestions include:
Maintain your electrolytes (电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.Ebola causes the death of a human being by ________.
| A．attacking him with high fever |
| B．regulating his immune system |
| C．damaging his immune cells |
| D．harming all his organs directly |
What is NOT mentioned as the symptom of Ebola?
| A．Fever and chills. | B．Swallowing difficulty. |
| C．Loss of blood. | D．High blood pressure. |
In order not to be infected by Ebola, we should _________.
| A．have the clothing of the infected cleaned |
| B．avoid eating wild animals like monkeys |
| C．not travel to Africa, America or Europe |
| D．stay at home without going anywhere |
It is true that ________.
| A．a certain number of people survive Ebola |
| B．human has found a special cure for Ebola |
| C．oxygen can save infected people’s lives |
| D．low blood pressure is surely caused by Ebola |
An American shopper, Emma Mumford, who was named “the Coupon(优惠券) Queen” has spent just £350 on a luxury(奢侈) Christmas for her and her family—but got £2,500 worth of food, drink and presents thanks to coupons and offers.
Ms Mumford is a so-called “extreme coupon ” and spends hours hunting out the best deals and bargains. She has been preparing for this Christmas since the end of the last one. Ms Mumford made the huge savings by checking price comparison websites and as a result collected more presents than she needed for Christmas. After sorting out gifts for all of her family, she has even been able to donate £1,000 worth of presents to her local hospital.
“It has been so nice to have Christmas sorted and not having to worry about breaking the bank. I wanted to get high quality presents for my family and show that you can do it without spending a fortune. There is a misunderstanding that everyone who does couponing only gets value products but through my careful shopping I have managed to purchase designer perfumes(香水), a high-end coffee machine .”she explained.
She said “What started as a hobby to help me save money has turned into my life and I am able to run a business helping people save money. I know what it feels like to struggle as my ex-partner had a lot of debt which I took on for him. We were in a poor situation where every penny counted. That’s what really inspired me.”
She has now turned her bargain-hunting addiction into a business where she searches for the best deals and offer tips to the general public through video blogging and her Facebook Page.
“I try and show people that it is just a little bit of work in the beginning but it will eventually pay off. One of the best things to do is just to be a bit forward thinking and save throughout the year.”

Over the last 25 years, British society has changed a great deal or at least many parts of it have. In some ways, however, very little has changed, particularly where attitudes are concerned. Ideas about social class --- whether a person is “working class” or “middle class” are one area in which changes have been extremely slow.
In the past, the working class tended to be paid less than middle-class people, such as teachers and doctors. As a result of this and also of the fact that workers’ jobs were generally much less secure, evident differences in lifestyles and attitudes came into existence. The typical working man would collect his wages on Friday evening and then, it was widely believed, having given his wife her “housekeeping”, would go out and squander (挥霍) the rest on beer and betting.
The stereotype (模式化的思想) of what a middle-class man did with his money was perhaps nearer the truth. He was --- and still is --- tended to take a longer-term view. Not only did he regard buying a house as a most important thing , but he also considered the education of his children as extremely important. Both of these provided him and his family with security. Only in very few cases did workers have the opportunity ( or the education and training ) to make such long-term plans.
Nowadays, a great deal has changed. In a large number of cases factory workers earn as much, if not more, than their middle-class administrators. Social security and laws have made it less necessary than before to worry about “tomorrow”. Working class people seem slowly to be losing the feeling of inferiority（自卑） they had in the past. In fact there has been a growing tendency in the past few years for the middle classes to feel slightly ashamed of their position.
The changes in both lifestyles and attitudes are probably most easily seen among younger people. They generally tend to share very similar tastes in music and clothes; they spend their money in having a good time, and save for holidays or longer-term plans when necessary. There seems to be much less difference than in precious generations. Nevertheless, we still have a wide gap between the well-paid (whatever the type of job they may have) and the low-paid. As long as this gap exists, there will always be a possibility that new conflicts and jealousies will arise, or rather that the old conflicts will re-appear, but between different groups.
According to the passage, which of the following is not a typical feature of the middle class?
| A．Desiring for security. |
| B．Making long-term plans. |
| C．Having vision for the future. |
| D．Saving money. |

| A．Changes are slowly taking place in all sectors of the British society. |
| B．The gap between working class and middle class young people is narrowing. |
| C．Difference in income will remain but those in occupation will disappear. |
| D．Middle-class people may sometimes feel inferior to working class people. |
The old man fished alone in a small rowboat and he had gone eighty-four days now without taking a fish. In the first forty days a boy had been with him. But after forty days without a fish the boy’s patents had told him that the old man was now bad luck, and ordered the boy to join another boat, which caught three good fish the first week. It made the boy sad to see the old man come in each day with his boat empty and he always went down to help him carry in the fishing lines or take down the old, patched sail.
“Santiago,” the boy said to him as they dragged up the boat to the sand. “I could go with you again. I’ve made some money.” the old man had taught the boy to fish and the boy loved him. “No,” the old man said. “You’re with a lucky boat. Stay with them. You must obey your father.” “We can be lucky again too. Remember when we didn’t catch a fish for 10 days, then caught a big one each day for a month?” said the boy. “Can I offer you a beer on the balcony and then we’ll take the stuff home,” said the boy. “Why not?” the old man said.
“Santiago,” the boy said as they sat on the balcony, “If I cannot fish with you, I would like to serve in some way.” “You bought me a beer,” the old man said, lifting the bottle to his mouth. “Do you remember the first time I took you out to fish?” the old man asked. “I was five. I remember the tail of a huge fish slapping against the boat, the noise of you clubbing him and the sweet blood smell. I remember everything from when we first went together,” the boy said. The old man looked at him with his sun-burned, loving eyes.
“May I get some sardines for tomorrow? Let me get four fresh ones,” said the boy. “One,” the old man said. His hope and his confidence had never gone. But now they were freshening like a sea breeze. “Two,” the boy said. “Thank you,” the old man said. He was too simple to wonder when he had attained modesty. But he knew he had attained it and he knew it was not disgraceful and it carried no loss of true pride. “Tomorrow is going to be a good day with this wind,” he said. “I will row far out before it is light. There will going to be a good day with this wind,” he said. “I will row far out before it is light. There will be a big fish?” asked the boy. “I think so. And I know many tricks.”Why was the boy forced to stop working for the old man?
| A．It was too dangerous to continue fishing. |
| B．It was time for the boy to return to school. |
| C．The old man was thought to be a poor teacher. |
| D．The boy couldn’t earn enough money with the old man. |
In paragraph 2, the boy probably mentioned their past fishing experiences in order to
__________.
| A．convince the old man that he should not retire |
| B．explain why he had to stop working for the old man |
| C．persuade the old man to let him return as his assistant |
| D．warn the old man about the danger of fishing in the deep sea |
Which of the following did the boy NOT do for the old man?
| A．Buy him a beer. | B．Repair the sail. |
| C．Drag up the boat. | D．Take in the fishing equipment. |
What can we lean about the old man from the last paragraph?
| A．He remained optimistic about catching fish. |
| B．He was the most skillful fisherman in the village. |
| C．He would stay out longer than any other fisherman. |
| D．He would usually go out further than any other boat. |
