2. 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. What does the term “digital detox” 【Para. 2】 mean?

5. . Passage Twenty All friendships require a certain amount of chemistry. But when two people of the opposite sex become friends， sometimes those friendly feelings can start to resemble something more like sexual tension. Male-female friendships can be an emotional minefield of hidden desires. Does this mean you secretly want to jump into bed with all of your friends? Of course not. But do you ever wonder how many of them might be interested if the opportunity presented itself? Maybe you and your platonic (柏拉图式的) friendship are just a bad breakup and a bottle of wine away from crossing that boundary and hooking up (结合). So can two people of the opposite sex ever really be “just friends?” The Hollywood answer to this age-old question is a decisive HELL NO. On screen， male-female friendships always turn into something more. Harry and Sally， Chandler and Monica， Jim and Pam … … Do I need to go on? Even the characters in Just Friends wind up becoming much more than the film’s definitive title suggests. Cinematic stories dictate that when reasonably attractive men and women befriend one another， they are always on the road to romance， whether they realize it or not. But how much truth is there to this friendship as foreplay theory? It is not a whole lot. Real life isn’t a romantic comedy. Men and women go to school together， work together and hang out in plenty of platonic settings without falling hopelessly in love with one another. Last year， a close female friend of mine moved in with a new male roommate. My immediate reaction was， “You two are definitely going to sleep together.” It seemed to me that a single man and woman living under the same roof would inevitably end up doing it. Much to my surprise， the roommate romance never happened. Almost one year later， the two of them have never even come close to seeing each other naked. Instead， their way of life has come to resemble a sexless marriage. They cook for each other， argue over domestic chores and insist that they never， ever think about each other “that way.” In the last paragraph， the man and the woman ( ) .

A. never become close friends

B. end up sleeping together

C. end up with a sexless marriage

D. never have romance

1. 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 . In Paragraph 2， “repressing” means ( ) .

A. releasing

B. suppressing

C. expressing

D. reasoning

3. 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” .According to the passage， which of the following is NOT true?

A. Social change tends to meet with more difficulty in basic and emotional aspects of society.

B. Disagreement with an argument about conditions tend to slow down social change.

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 Seven A few centuries ago， people looked at the birds and wondered what it would be like to fly like them. There were stories of heroes who glued bird feathers on their arms and flew up into the sky. About 500 years ago， some people dreamed a different dream. Instead of flying up to the sky， they dreamed of falling from the sky! In the 15th century， Italian inventors designed a cone-shaped (雏形) device that was supposed to bring a man down safely from a great height. The operator held on to a handle with straps strapped to his waist. This was the first known design for a parachute (降落伞) . Even the great inventor Leonardo da Vinci sketched a type of parachute. His parachute design was in the shape of a pyramid (金字塔). Other inventors also sketched their own designs for a parachute. Unfortunately， these were only designs on paper and no one tested them . A Croatian inventor named Fausto Veranzio looked at Leonardo da Vinci’s parachute design and replaced the pyramid shape with one that looked like a sail from a ship. When Veranzio was 65 years old， he fell ill. Thinking he would not live longer， he decided to try out his parachute invention. He built his parachute using wood and cloth. Strapping his invention to his waist， he jumped off the tall bell tower in his city. He landed safely! He was supposedly the first man to successfully use a parachute. However， some people thought this story was not true. If that was the case， then the first person to successfully use a parachute would go to a Frenchman named Louis-Sebastien Lenormand in 1783 .Leonardo da Vinci’s parachute was shaped like a ( ) .

1. Passage Seventeen No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground. Somehow， he learned to make words. As the centuries went by， he made more and more new words. This is what we mean by language. People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. Each contains many thousands of words. A very large English dictionary， for example， contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life. The words you know are called your vocabulary. You should try to make your vocabulary bigger. You’re supposed to read as many books as you can. There are plenty of books written in easy English for you to read. You will enjoy them. When you meet a new word， you should find it in your dictionary. Your dictionary is your most useful book. From this passage， we know that ( ) .

A. man never made sounds
