Instead, it's purposeful practice. Top performers spend more hours practising their craft. If you wanted to picture how a typical genius might develop, you'd take a girl who possessed a slightly above average language ability. It wouldn't have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.‎ This contact would give the girl a vision of her future self. It would give her some idea of a fascinating circle she might someday join. It would also help, if one of her parents died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She'd be able to see new writing in deeper ways and quickly understand its inner workings. ‎ Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, she delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious, automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback. viewing her performance from the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems——how do I get characters into a room——dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.‎ The primary quality our young writer possesses is not some mysterious genius. It's the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we're "hard-wired" to do. And it's true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.‎ ‎21. The passage mainly deals with __________.‎ A. the decisive factor in making a genius B. the relationship between genius and success C. the function of I.Q. in cultivating a writer D. the way of gaining some sense of distinction ‎22 .By reading novels and writers' stories, the girl could .‎ A. come to understand the inner structure of writing ‎ B. join a fascinating circle of writers someday C. share with a novelist her likes and dislikes D. learn from the living examples to establish a sense of security ‎23. In the girl's long painstaking training process, .‎ A. her adviser forms a primary challenging force to her success B. she comes to realize she is "hard-wired"' to write C. she acquires the magic of some great achievement D. her writing turns into an automatic pattern of performance ‎24. What can be concluded from the passage?‎ A. A fuelling ambition plays a leading role in one's success.‎ B. A responsible adviser is more important than the knowledge of writing.‎ C .What really-matters is what you do rather than who you are.‎ D. As to the growth of a genius, I.Q. doesn't matter, but just his/her effort.‎ B Many of us are quick to blame others for how we feel: “He makes me so mad!" or “She really hurt my feelings. "But did someone really" make me angry "or are we feeling the anger in us getting kicked up in response to the way someone behaved towards us？‎ The difference between the two is in who the responsible party is for the way we feel. If we blame others for our feelings we will eventually feel reasonable at whatever our retaliation（报复）may be，and we will explain that it was their fault，not ours. "They were driving me mad”.‎ When we blame others for the way we feel we have in fact given power to others for the state of our emotional wellbeing（健康）. The truth is，no one controls our feelings but us. If we are finding that people in our lives really know how to" push our buttons" then we are not doing a good enough job at protecting our " buttons. "We are the ones leaving our buttons out in the open so that other people can" push them. "Ultimately，the switch for our buttons is inside us-not on the outside.‎ While there are some things in life that are clearly out of our control，like the weather or a flight that's two hours late，how we act and respond to other people's behavior is not among them. Our responses to others are well within our control.‎ If someone is "making us" so mad，for example，that we get angry，we are not doing enough to learn about what drives our anger and how to properly cope with it. My suggestion is taking time before you get angry. and putting some work into taking an inventory（清单）of the past. An inventory can show you how much of your past experiences influence your feeling reactions in the current moment.‎ When we finally realize that so much of our present feelings and reactions are driven from within ourselves and our own past experiences，we will be ready to make the changes in our lives that will better secure our buttons so that they are no longer left out in public for everyone to push at will.‎ ‎25. What result will appear if we blame others for our emotions?‎ ‎ A. We consider others to be correct.‎ ‎ B. We consider ourselves to be correct.‎ ‎ C. We consider we were driving ourselves mad.‎ ‎ D. We consider they were driving themselves mad.‎ ‎26. What's the author's attitude towards feelings?‎ ‎ A. We should blame others for the way we feel.‎ ‎ B. We should enable others to control our feelings.‎ ‎ C. We should let others know our daily life clearly.‎ ‎ D. We should control personal feelings ourselves.‎ ‎27. According to the author, which can always be under our control?‎ ‎ A. The weather conditions. B. The delay of a flight ‎ C. Other people's feelings. D. Our own behavior.‎ ‎28. Which proverb best suits the author's advice in Paragraph 5?‎ ‎ A. A burden of one's choice is not felt. B. A friend is easier lost than found.‎ ‎ C. Think twice before acting. D. A good beginning is half done.‎ ‎29. What does the underlined phrase "push our buttons" probably mean in Paragraph3?‎ ‎ A. Force us to do a god job. B. Make us angry.‎ ‎ C. Take off our buttons. D. Let us down.‎ C ‎ When Jessa was five years old her parents were killed in a car accident. Her life had changed forever. Jessa was told that they were unable to find any relatives to take her. The next thing she remembered was packing her clothes and being hurried to the local orphanage.‎ ‎ Friends were hard to make and keep at the orphanage because once you would make a friend, they would be placed in a foster (领养) home. Jessa would watch her friends get into the car and drive away. Some of them would return but always seemed so different to her. Some had been beaten while others had been starved and some came back because the family had had a baby. Jessa never gave much thought to being adopted until one day the social worker came and took her to the main office to meet a family. Jessa was told they wanted to foster her.‎ ‎ Reluctantly Jessa left her comfort zone and headed out to her new home with Mr. and Mrs. Johnson. She loved her new home and they were the nicest people she had ever met. They would play for hours and at night they both would read her a bedtime story. Every morning she would wake to the smell of pancakes, eggs and bacon. Then Mr. Johnson would come in and say，“Wakey wakey eggs and bacy. ”It always made Jessa laugh to hear him say that. They always had meals together like a real family.‎ ‎ One night after dinner they told Jessa they wanted to adopt her and that they would get all the paperwork done the following week. Jessa was ecstatic (狂喜). She was finally going to have a real family. That weekend Mrs. Johnson went to see her sister and tell her the good news and Mr. Johnson and Jessa stayed behind to go to the zoo. Upon their return, Mr. Johnson received a phone call, saying his wife had been in an accident and didn't make it. He decided it would be better if he sent Jessa back to the orphanage.‎ ‎ Jessa's heart was broken when Mr. Johnson told her she would be going back. Eyes filled with tears, Jessa climbed the stairs to her room to pack. Her little heart had been shattered for the second time in her short life. Jessa dressed for bed wondering if Mr. Johnson was going to read her tonight. After waiting for almost an hour, she gave up on that thought and climbed into bed. Jessa lay awake and turned for hours before she finally fell asleep.‎ ‎ The next morning she woke up, got dressed and headed down stairs, hoping Mr. Johnson had changed his mind and wanted to keep her. When she stepped into the kitchen she knew he hadn't, for the bags she had packed the night before were sitting by ‎ the door. Mr. Johnson opened the door and there stood a social worker to take her back. Her little head hung low as she picked up her bags and walked out the door never to see sweet Mr. Johnson again. She climbed into the social workers' car. Jessa just hung her little head and let tears roll down her cheeks, but she quickly wiped away.‎ ‎ By the time they made it to the orphanage, Jessa had promised herself that she would never let her heart be broken like that again, and she would never become attached to anyone ever again. The days at the orphanage were long and dreary especially for Jessa. She had no friends and made no attempt to make any. She had been called in twice to speak to the counselor about why she chose to stay to herself and she always told them the same thing—— it was easier for her that way. If you didn't get attached to anyone it wouldn't hurt when they left.‎ ‎30. The primary factor contributing to Jessa's being reduced to orphanage life was that__________.‎ ‎ A. she herself was a Jonah B. no relatives would take her home ‎ C. the babysitter was absent D. she lost parents to a terrible accident ‎31. What can be inferred from the third paragraph?‎ ‎ A. Kids resisted making friends in orphanage.‎ ‎ B. All adopted kids were not treated well in foster families.‎ ‎ C. Only those rich families were qualified to adopt a child.‎ ‎ D. Orphanages were usually full of violence and bullies.‎ ‎32. What do we know about Mr. Johnson?‎ ‎ A. He cheated Jessa. B. He was a man with no honesty.‎ ‎ C. He was kind but felt helpless. D. He was rich but cold- blooded.‎ ‎33. The underlined word “shattered” in the fifth paragraph probably means__________.‎ ‎ A. insulted B. hurt C. touched D. embarrassed ‎34. Jessa couldn't help weeping when leaving Mr. Johnson's house because __________.‎ ‎ A. she lost a chance of having a real home ‎ B. she hated Mr. Johnson for his cruelty ‎ C. she was afraid of orphanage life ‎ D. Mrs. Johnson died for the same reason as her parents did ‎35. What does the passage mainly talk about?‎ ‎ A. Misfortune never comes alone，‎ ‎ B. It's no use crying over the split milk.‎ ‎ C. It's intolerable to repeat bitter experience.‎ ‎ D. Nothing can compensate for the loss of love.‎ 第二节 七选五（共5小题; 每小题2分，满分10分）‎ 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。‎ Urban Wildlife Cities are diverse ecosystems. In addition to visitors from the wild, a large number of species share our urban areas. As our cities spread, we need to think about what it is like for other species to have human neighbors.‎ Cities are built for humans. ___36____For example, most city parks are kept neat and tidy so that humans will find them beautiful.

The bats are a tourist attraction, and they eat lots of bugs every night.‎ There are also structures built with the aim of bringing wildlife into the city. The Beijing Olympic Forest Park is a good example. The park used native plants and created open, natural spaces for wildlife. The result is a zone in Beijing with over 160 species of birds.

Then grab your hiking boots and a tent. A new study suggests that a couple days of camping in the great outdoors can reset your circadian clock and help you get more sleep.‎ ‎ The circadian clock, more commonly known as the body clock, is an internal system that tells our bodies when it’s time to go to sleep and when it’s time to wake up. Scientists track this clock by measuring the amount of melatonin circulating in a person’s blood at any given time. In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high through the night, and then settle back down when it’s time to wake up.‎ ‎ In our modern society, however, most of us stay up many hours past sunset and would probably sleep in many hours after sunrise if we could. And the trouble is, your melatonin levels may still be high when your alarm clock goes off in the morning, which leads to grogginess. It may also have other health consequences as well, such as diabetes, overweight and heart disease.‎ ‎ Professor Kenneth Wright of the University of Colorado in the US wanted to see if our body clocks can be reset by a short stay in nature. His team recruited 14 physically active volunteers in their 20s and 30s. Nine went on a weekend camping trip, while the other five stayed home. At the end of the weekend, the researchers reported that in just two days, the campers’ body clock had shifted so that their melatonin levels began to rise more than an hour earlier than they did before they left on the trip. By contrast, the body clocks of the group that stayed home shifted even later over the course of the weekend. “This tells us we can reset our clocks fast,” Wright said.‎ ‎ Therefore, if you want to change your sleep patterns you could try to increase your exposure to natural light during the day and decrease the amount of artificial light you see at night.‎ ‎___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________‎ 周测二答案 听力： 1-10 BCBCA CACBA 11-20 CBCBC A BBAA 阅读： 21-24： AADC 25-29： BDDCB 30-35: DBCBAC 七选五：36-40 DBFEC 完型：41-50 ADABC BADDB 51-60 BBCDC CABAC 语法填空： ‎ ‎61. watching 62. the 73. who/that 64. influential 65.

The circadian clock, an internal system, schedules your sleeping time guided by the amount of melatonin. But people’s irregular sleeping habit disturbs the rise and fall of melatonin, which causes tiredness and diseases. Wright's experiment proved that our clocks can be reset. So we'd better expose ourselves to natural light more than artificial light.‎
