After a little ____6____ he found that he was becoming very ___7___ and soon he was making some of the finest tacks. Old Mr. Smith died, and because of the war, the son ____8____ all his goods. He had to leave home and live in a village in another country. In this village, there were large numbers of shoemakers who were spending a lot of money on tacks for their shoes, and sometimes ___9____ when they paid high prices they were not always able to _____10_____ what they wanted, because in that part of the country there was a great _____11_____ of tacks for soldiers' shoes. Our young Mr. Smith, who was finding it difficult to earn (挣) his daily bread, remembered that once upon a time he had learned the _____12_____ of making tacks and had the sudden idea of making a bargain (交易) with the _____13_____. He told them that he would make the tacks if they would _____14_____ him to get settled (安顿) in the workshop. The shoemakers were only too glad of the bargain. And soon, young Mr. Smith found that he was making the finest tacks in the village. “How _____15_____ it seems,” he said with a smile, “even making tacks can bring me good luck. My trade is more useful to me than all my former (从前的) riches.” ( )1．A．creative B．hard-working C．wealthy D．generous ( )2．A．testing B．seeing C．watching D．explaining ( )3．A．wash B．win C．force D．try ( )4．A．hammer B．experience C．skill D．time ( )5．A．cares B．knows C．complains D．thinks ( )6．A．exam B．control C．practice D．check ( )7．A．skilled B．excited C．tired D．worried ( )8．A．carried B．lost C．sold D．harmed ( )9．A．ever B．instead C．although D．even ( )10．A．protect B．get C．make D．remember ( )11．A．number B．power C．need D．price ( )12．A．art B．problem C．importance D．achievement ( )13．A．blacksmiths B．soldiers C．shoemakers D．villagers ( )14．A．accept B．help C．refuse D．return ( )15．A．simple B．funny C．lively D．Possible 6、 六选五 Much of the work in today's world is accomplished in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. ___1___ Companies spend millions hiring top business people. Is their money well spent? ___2___ They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team’s performance. To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate (协调) their actions. ___3___ In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team performance. Young children learning to play team sports are often told, "There is no I in TEAM.” ___4___ Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war (拔河比赛), whenever a person is added, everyone else pulls the rope with less force. ___5___ An A-team may require a balance—not just A players, but a few generous B players as well. A．It's not a simple matter to determine the nature of talent. B．Sports team owners spend millions of dollars attracting top talent. C．Stars apparently do not follow this basic principle of sportsmanship. D．Several recent studies examined the role of talent in the sports world. E．Building up a dream team is more complex than simply hiring the best talent. F．This task interdependence distinguishes baseball from football and basketball. 1.____________ 2.___________ 3.____________ 4.___________ 5.____________ 7、 回答问题 Enough Sleep Could Reduce Risk of Injury A new study suggests that enough sleep is necessary and important for people. The researchers found that people who got no more than four to five hours of sleep a night were easier to be hurt than those who slept eight hours or longer. Compared to those who slept eight hours or more each night, people who slept less than seven hours were more likely to experience a musculoskeletal(骨骼) injury(伤害). The risk climbed as the hours of sleep dropped, with a 53-percent greater injury risk at six hours of sleep. The study notes that getting enough rest could be a better way to reduce injury risk. Dr. Hohui Wang is in the University of California, San Francisco. He said that getting too little sleep leads people to be more likely to get hurt. So getting extra sleep might help. Most people are healthiest and perform their best with seven to nine hours of sleep a night, said Captain Jeffrey Osgood. Osgood said, “The less we sleep, the worse we perform in everyday life.” So he offered suggestions for how people can get more – and better-quality(质量) – sleep. “Please avoid coffee and exercise before sleeping; it’s a better way to keep your bedroom dark and quiet. What’s more, please keep your phone out of bed. 1．What are the dangers of sleeping less than seven hours according to the passage? ______________________________________________________________________ 2．Please show a better way to reduce injury risk according to the passage. ____________________________________________________________________ 3．How many hours of sleep are the best for people? ____________________________________________________________________ 4．Please translate the underlined sentence into Chinese. ____________________________________________________________________ 5．What shouldn’t we do to get better quality sleep?(More than 2 examples) ______________________________________________________________________ 8、 首字母填空 The problem some people have with homework is not that they find it too hard, or that it takes too long, but that they f___1___ what they have to do and for when. This may be because they don’t write down exactly what n____2____ to be done, or don’t make a note of when it has to be handed in. If you have a planner for school, make good u____3____ of it to record what you need to do. If not, use a diary or notebook to make notes of what has to be handed in and w___4___. You could set up an “ in-tray”  system, so you can see what is w____5____ to be done. This is a tray or shallow box where you put your homework each night until you are r___6___ to do it. Although no one exactly looks forward to doing homework, you will get it done more efficiently(高效地)if you are well o____7____ and have time and space to concentrate(专注)on it. For example, if your homework involves(需要)going online and you don’t have your o___8___computer, make sure you ‘book’ some time on the family computer, or can use one in your school library. If you have space, set up a homework ‘office’ a___9___ at home with a table or desk and a comfortable chair. It should have good light, a place for your books, and your homework ‘tool kit’. It helps to get into a habit of doing homework early in the evening, and not l___10___ it until the last minute at weekends. After you’ve done it, reward yourself with some fun, ‘down-time’ activities, such as some television or social networking time. 1.____________ 2.___________ 3.____________ 4.___________ 5.____________ 6.____________ 7.___________ 8.____________ 9.___________ 10.___________ 9、 任务型阅读 Pollution is the process of making land, water, air or other parts of the environment dirty and may do harm to people. Things as simple as light, sound and temperature (温度) can be thought as pollutants when introduced artificially (人为地) into the environment. Land pollution Land can become polluted by household garbage and by industrial (工业的) waste. In 2014, Americans produced about 258 million tons of solid waste, according to the USA Environmental Protection Agency. A little over 50% of the waste — 136 million tons — was gathered in landfills. Only about 34 % was recycled. Noise pollution Even though humans can’t see or smell noise pollution, it still affects the environment. Noise pollution happens when the sound reaches harmful levels. Research has shown that noise is a direct cause to health problems, including stress related illnesses, high blood pressure and hearing loss. For example, a study found that noise pollution may contribute to (导致) hundreds of thousands of deaths per year by increasing the rates of coronary heart disease. Light pollution Most people can’t imagine living if there were no electric lights. For the natural world, though, lights have changed the way that days and nights work. Some consequences (后果) of light pollution are: Some birds sing at unnatural hours in the presence of artificial light. Light pollution also makes it difficult for astronomers (天文学家) to properly see the stars. Plants’ flowering and developmental patterns can be entirely disrupted (打乱) by artificial light. Pollution facts: the process of making environment dirty and may be ___1___ to people ___2___of pollution Details Land pollution Land can be polluted by waste from household and ___3___ . Over ___4___ of the waste was gathered in landfills. Only about 34% was ___5___ . ___6___ pollution Sound reaching harmful levels can lead to health problems ___7___ . Hundreds of thousands of people ___8___ of heart disease per year because of noise pollution. Light pollution It’s impossible to live ___9___ electric lights for most people. There are some consequences of light pollution: Some birds sing at unnatural hours. It’s not ___10___ for astronomers to see the stars clearly. Plants’ flowering and developmental patterns can be disrupted. 1.____________ 2.___________ 3.____________ 4.___________ 5.____________ 6.____________ 7.___________ 8.____________ 9.___________ 10.___________ 10、 写作 假设你叫Tom, 你们学校要推荐一名“最美学生”，你想推荐Sam。请根据表格内容，写一封90词左右的推荐信。信的开头和结尾已给出，不计入总词数。 姓 名 Sam 性格、品质 自信 不害怕在许多人前面演讲； 勤奋 对学习标准高； 有条理 …… 乐于助人 …… 在校： 在家： 尊敬师长，团结同学 ； ………… 喜爱的服装和颜色 蓝色T恤和黄色长裤，因为蓝色……，黄色……（请适当发挥） 其它 有爱心，经常参加慈善活动，把绝大部分业余时间用于帮助需要帮助的人。 Dear Mr. Wang, I’m writing to recommend Sam as the most beautiful student.
