2. Passage Fifteen Big data can be defined as information that is too big or complex to be contained or processed by any one machine or person. As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy. When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology. Now， he is part of the big data industry that includes Google and Facebook. Dailly’s research company， Morar Consulting， started three years ago with five employees. The company’s earnings have increased by 25% each year. It now employs 90 people. “What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said. He noted the importance of working with people with different skills. “We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and salespeople，” Dailly said. Companies like Dailly’s employ recent college graduates. The industry profits from the ideas of these young men and women. New forms of data also make it possible for some observers to predict the future. They are more valuable to companies than the traditional forms of data recording or reporting. “We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done. That helps people take proper action in advance. This makes it much more useful for strategy.” Julian Dailly dismisses concerns that computers have finally taken control of our daily lives. “Some may worry that humans will be allowed to be replaced by machines. I think it’s a fantasy.” Dailly’s company focuses on businesses in ( ) .

4. Passage Eleven Doctors say anger can be an extremely damaging emotion， unless you learn how to deal with it. They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer. Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm and reasonable way. Others burst with anger， screaming and yelling. But still others keep their anger inside. They cannot or will not express it. This is called 【repressing】 anger. For years some doctors claim that both repressing and expressing anger can be dangerous. They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙). They spend the heart rate， raise blood pressure or sugar level in the blood. As a result， the angry person feels excited and is ready to react. The violent reaction may lead to high blood pressure. However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it. They believe that those who keep their anger inside may face a greater danger of heart disease. Most doctors agree that it is important to learn how to deal with anger. They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about. If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably. They also believe that a good way to deal with anger is to find humor in the situation that has made you angry. After all， it is much healthier to laugh than to get angry .What is the best title for this passage?

5. Passage Twenty-Four Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas， more disagreements in interest， and more groups and organizations with different beliefs. In addition， there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways， there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory， they are at least customary and undisputed. Within a society， social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material， for example， in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore， social change is easier if it is gradual. For example， it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies ( 一分为二). This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts” .Social change is less likely to occur in a society where people are quite similar in many ways because ( ) .

2. Passage Nineteen A 3-year-old boy who was lost in the woods for two days is now safe at home. But Casey Hathaway told his rescuers that he was not alone in the rainy， freezing cold woods. He said he was with a friend——abear. The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not， the family searched the area for almost an hour before calling the police. Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still——no Casey. The woods of North Carolina are home to many black bears， like this one. It seems one of them helped a little boy while he was lost in the woods. Then on January 24， someone called the police saying they heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some briar (荆棘). He was in good health. Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud， rainy weather， but that “he did say he had a friend in the woods that was a bear that was with him. ” Hundreds of people helped in the search and rescue efforts， including some 600 volunteers， federal police and members of the military.
