1. Passage Ten Nowadays， children heavily cling to digital devices such as computers and smart phones. Some spend up to six hours a day on their digital devices. They can be playing games online with people elsewhere， updating their status on social media， texting friends， or looking for the latest apps to download to their computers or smart phones. This worried Martin Strott. He is the headmaster of the Old Hall School in Wellington， England. He was so concerned that he challenged his students to take part in a week of 【 “digital】 【detox”】， a program to reduce their reliance on digital devices. Mr. Strott told the local newspaper， the Shropshire Star， that too much screen time would affect the development of their social skills. At another interview with a magazine， he mentioned that this over-reliance on digital devices “takes away family time and reduces their chances of face-to-face communication” . The parents are happy with the program. But what about the children? Nine-year-old Fred usually spends around two hours on his digital devices at home after school and around 12 hours on weekends. For him， the digital detox experience was “really hard” . He said that he had been engaged in many interesting outdoor activities organized by the headmaster， but still missed his phone and online games. The idea of keeping children away from their digital devices for a while to prevent too much dependence on them is not particularly new. There have been similar practices in the United States. But are they effective in the long run? According to Mr. Strott， even if kids go back to their digital devices， the hope is that at least they will think about how they will use their time. According to Paragraph 1， what would children do when they cling to their digital devices?

4. Passage Twelve What are the differences between public and private in American higher education? A big difference involves money. Public colleges and universities charger for an education just like private schools. But state schools cost less because they get money from the states that started them to educate local citizens. As a result， out-of-state and international students usually pay more than state residents， at least the first year. The state with the most residents， almost forty million， is California. Its systems of two-year and four-year colleges and universities are among the largest in the world. But the example we are going to focus on today is to the north of California， in a much smaller state on the West Coast: Oregon. The University of Oregon， located in Eugene， is one of the campuses in the Oregon University System. The cost for undergraduates this year is $6，000 for state residents. Housing is an additional $8，000. Non-residents pay the same for housing——but almost $20，000 for tuition and fees. Let’s see how these numbers compare to a private college in Oregon. Lewis and Clark College in Portland has 4，000 students， compared to 20，000 at the University of Oregon. Housing costs $800 more than at the state school. But the big difference is tuition. The published price at Lewis and Clark is almost $34，000. Yet Lewis and Clark is one of the few American colleges to offer financial aid for international students. Each year it awards financial aid to twenty students from other countries. And it says the average award last year was 19，000 dollars. That would make Lewis and Clark cheaper for international students than the University of Oregon. But， of course， prices alone do not say anything about the quality of a school or the value of an education. The costs of tuition and housing in Lewis and Clark College are ( ) .

A. both more expensive than in the University of Oregon

B. cheaper for foreign students than in the University of Oregon

C. the same as that in the University of Oregon

D. cheaper than those of the University of Oregon for the state residents

33. Early in the day came the news (_____)_ Germany had declared war on Russia.

A. 　 which

B. 　 what

C. 　 that

D. 　 whose

3. 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.” The company’s staff is characterized by all the following EXCEPT ( ) .

A. fresh ideas

B. young age

C. mixed education backgrounds

D. rich experience in the field

3. Passage One There are three separate sources of danger in supplying energy by nuclear power. First， the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built， the containers used for the transport of the materials are not. Normally， only two methods of transport are in use， namely road or rail. Unfortunately， both of these may have an effect on the general public， since they are sure to pass near， or even through， heavily populated areas. Second， there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive， so they must be stored in one of the inconvenient ways that scientists have invented. For example， they may be buried under the ground， or dropped into deserted mines， or sunk in the sea. However， these methods do not solve the problem， since an earthquake could easily break the containers.
Third， there may occur the danger of a leak or an explosion at the power station. Compared with the other two dangers， this is not very likely， so it does not provide a serious objection to the nuclear program. However， it can happen. Separately， these three types of dangers are not a great cause for worry. Taken together， though， the probability of disaster is extremely high. What do we learn from the last paragraph?

A. By itself， none of the three dangers is very likely to cause much worry.

B. The dangers of nuclear energy can be prevented.

C. The general public are strongly against the nuclear program.

D. The power station is a safe place.

2. 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” .( ) is one of the factors that tend to promote social change.

A. Joint interest

B. Advanced technology

C. Less emotional people

D. Different points of view

C. Social change is more likely to occur in the material aspect of society.

D. Social change is less likely to occur in what people learned when they were young.

2. Passage Fourteen For a long time， people have disagreed about whether golf is a sport or a game. On one side of the argument， people say that golf meets the dictionary definition of a sport， because it is a physical， athletic activity. They add that golf is recognized as a sport by sporting goods companies， athletic groups， fans， and the media. Also， golf’s inclusion in the Olympics in 2016 is more proof that it is sport. On the other side， people say that golf is a game， not a sport. They say golf is not a very physical activity and can be played well by people who are overweight or injured. Also， golf was only recently added to the Olympics. For more than 100 years it was not included in the Olympic Games. For many， the Olympic Games serve as a measurement for whether an activity should be called a sport. Golf was first included in the Olympics in 1900. However， it was removed shortly thereafter because of a lack of participation and conflict with other golf events. Through the years， there were several attempts to bring golf back to the Olympics. It wasn’t until the 2016 Summer Olympics in Rio de Janeiro， Brazil that golf returned. Some say the return of golf does not prove that it is a sport. Rather， it only proves that the Olympics wanted to benefit from the star power of famous golfers like Tiger Woods. The disagreement continues today. Those who think golf is a sport point to pro-golfers like Woods， who are strong and fit. Those who disagree point to golfers like John Daly. He is a successful pro-golfer who once had health problems. So is golf a sport? The answer depends on who you ask——and whether that person owns a set of golf clubs.The overweight or injured people are mentioned in Paragraph 3 to ( ) .

A. demonstrate the popularity of golf

B. indicate the special function of golf

C. prove that golf is more of a game than of a sport

D. show the physical， athletic nature of golf
