Gone, for the most part, are the ankle-hugging high-tops that supposedly ____41____ to protect players from injury.The change over the last few years to low- top sneakers(运动鞋) seems to go against conventional wisdom. Strangely, __42___, Steven Nash and Kobe Bryant, two of the most __43__players with the Los Angeles Lakers, aren’t worried.According to the US market-research firm NPD Group, high-tops once ___44__ for about 20 percent of the US basketball shoe market. Now, the number has sunk to about 8 percent. Low-tops, the kind that Nash and Bryant wear, have grown to 29 percent, from just 11 percent in 2002.High-top sneakers are one of the most celebrated __45___ in modern basketball. After the 1985 Air Jordans so transformed the market, shoe companies began battling one another. They put air pumps in the tongues of their shoes and made carefully prepared and organized __46__.“All of a sudden it became a __47__ business,” Marshal Cohen, an analyst with NPD group, told The Wall Street Journal. The Jordans were excellent. The market went from being nothing to a million-dollar business __48___.”One of the reasons high-tops are not so __49__ anymore is that they were never really very good at protecting the feet.In an article in the British Journal of Sports Medicine in 2008, University of Newcastle researcher Craig Richards found no evidence that sneakers__50__ injuries. His research actually found that high-top basketball sneakers could even cause players to run slower and jump lower. Now, the contest has become a war. Companies like Adidas, Nike, Converse and Reebok are all fighting to create the next “Air Jordan,” and with the next market battle.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Are you a graduate trying to plan out the best career path for yourself? Here, some tips are given on how to go about it.A university degree is no __51___ of a job, and job hunting in itself requires a whole set of skills. if you find you are not getting past the first interview, ask yourself what is happening. Is it a(n) __52__ to communicate or are there some skills you lack? And find out what you need t do to bring yourself up to the level of __53__ that would make you more attractive t them.Do not be too discouraged if you are __54__ for a job, but think about the reasons the employers give. Those who made the second interview might have been studying the same subject as you and be of __55__ ability level, but they had something which made them a __56___ match to the selector’s ideal. That could be experience gained through projects or vacation work, or it might be that they were better at communicating what they could offer. Do not take the comments at __57__ value: think back to the interviews that generated them and make a list of where you think the shortfall in your performance lies. With this sort of analytical approach you will eventually get your foot in the door.Deciding how long you should stay in your first job is a tough call. Stay too long and future employers may question your ___58__ and ambition. Of course, it depends on where you are aiming. If you are a graduate, spending five or six years in the same job is not too long provided that you take full advantage of the __59__. However, do not use this as a(n) __60__ for lacking interest or enthusiasm. Graduates sometimes fail to take ownership of their careers and take the initiative. It is up to you to make the most of what’s available within a company, and to monitor progress in case you need to__61__. This applies particularly if you are still not sure where your career path lies. It is helpful to think through what kind of experience you need to get your __62__ job and it is not a problem to move around to a certain extent.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A).Iceland, an island just south of the Arctic Circle, has fairly mild winters, thanks to warm ocean currents. Time your vacation here during the winter months to take advantage of off-season deals.Off-season means good deals on flights, hotels and tours. You may also find that the locals are a bit friendlier and more welcoming when tourists aren’t arriving in crowds. In the winter months, there are less than seven hours of daylight; thus, chances are good you’ll catch sight of the northern lights. Sun sets are also beautiful at this time, making for some great photo opportunities.In Iceland, winter is the perfect time to hike glaciers, go ice climbing, explore caves made out of hardened lava(岩浆) and much more. One of the most popular activities is off-roading(越野比赛) in a specially-equipped “super jeep”.Before booking your trip, be sure to check for volcano alerts. There are about 130 volcanoes on or around Iceland. Thirty-five of them are active. In 2010, a volcano named Eyjaallajokull exploded, sending clouds of ash up to four kilometers into the atmosphere. The ash drifted toward the UK and Europe. Because the ask could damage aircraft engines, airlines operating in the region were forced to cancel flights for six days. As a result, thousands of people were stuck in airports.Recently, another volcano named Bardarbunga has become active, erupting ash into the air. Such events, if large enough, could prevent your trip from going ahead. So check the latest volcano news prior to making your reservations.66. According to this article, why are you more likely to see the northern lights in the winter?A. They move from rural areas to cities.B. The weather is more stable at that time.C. They’re a special feature of many festivals.D. The sky is dark for lo nger periodsthen.67. According to the article, how do visitors to Iceland have fun in the winter?A. They learn how to ski down the mountains.B. They photograph famous historic sites..C. They explore the countryside in well made vehicles..D. They spend a week at one of the seaside resorts.68. What is true about the volcanoes of Iceland?A. The majority of them are quiet.B. Their age hasn’t been determined.C. All but one of them are extinct.D. Citizens aren’t affected by them.69.What does this article explain?.A. Some of Iceland’s urban cultural attractionsB. A way t reduce the cost of a trip to Iceland.C. Reasons for visiting Iceland in June and July.D. The average price for a short tour of Iceland.(B).SELF-REFLECTION OF TEACHING PRACTICES READING, WRITING,TALKINGSchool: Date:Grade(s) presently teaching:Please do not sign your name.

Mrs. Grace likes to share her version of tasks outcome in class, which could be labeled _____.A. ASSESSMENT OF LEARNINGB. KNOWLEDGE CONSTRUCTIONC. DEVELOPMENT OF STRATEGIESD. SELF-SELECTION(C)A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science. Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest. The huge amounts of data that are gathered come from many different locations and require special techniques for handling data. Important new tools that facilitate Earth system science include satellite remote sensing, small deep-sea submarines, and geographic information systems.More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts. Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water.Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographic information systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of information gathered at different times. For example,satellite remote sensing images of a forest can be converted to represent stages in the forest's growth. Two such images, made at different times can be overlaid and compared, and the changes that have taken place can be represented in a new image.74. The word "facilitate" in Paragraph I is closest in meaning to ________.A. enableB. requireC. organizeD. examine75. The author of the passage mentions that satellite observations are especiallyeffective in ________.A. conducting scientific studies of life on the ocean floorB. predicting future climate changesC. providing data to determine Earth's ageD. demonstrating interactions among all of Earth's parts76. According to the passage, satellite observations of the Arabian Desert allowarchaeologists to know ________.A). indications of ancient routes B. evidence of former lakesC. traces of early farmsD. remains of ancient forests77.What is the main idea of the passage?A. special techniques are needed to classify the huge amounts of data about Earth.B. New tools provide information about Earth that was once impossible to obtain.C. Advances in Earth system science have resolved many environmental problems.D. Satellite remote sensing can show changes between two images taken years apart. Section CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.For a sight of an evolving technology that promises to shake video gaming to its foundation, check out “Throw Trucks With Your Mind”.Unlike most video games, it doesn't rely solely on a mouse. Instead, its players also put on a headset that enables them to throw trucks or other virtual objects simply by thinking.And that's just for starters. Advocates of so- called neurogaming(交感神经游戏)say the concept in a few years will combine a wide variety of physiological factors, from a player's heart rate and hand gestures to pupil dilation(瞳孔扩张) and emotions. Moreover, they imagine many such games being developed to improve the health, brainpower and skills of those playing them.The electroencephalography(脑电波仪), or EEG, headset used to throw trucks and other objects onto enemies was made by San Jose, California.-based NeuroSky. It measures separate brainwave frequencies that reflect how focused the player is and how calm they are, according to Lat Ware of Emeryville, California., who developed the game. The game, which can be purchased at , costs $25, or $99 with the headset.Ware, 29, said it's possible to move a pear or other small virtual object if the player is calm, but not focused, or vice versa. But he said both mental states are essential toflatten an enemy with a huge truck, which takes considerable concentration. Although only a few neurogames have been introduced so far and their action tends to be fairly limited, the games are expected to become far more challenging - and multipurpose - as the software and related technology improves.One concept being explored is to develop games that adjust their action according to the player's changing emotions. These are measured by such factors as their facial expressions, eye movement and skin- conductance(皮肤导电) levels. Another approach is to make games that influence how the player thinks and feels.Consider Los Angeles- based Melon, which, like "Throw Trucks With Your Mind," was recently launched via the online fundraising site Kickstarter. Melon officials say their first game-- which challenges players to fold origami(折纸) with their mind, using NeuroSky's EEG headset -- helps people "learn how to focus, relax and meditate better."78. According to this article, what is the purpose of developing the new kind of games?79. The function of brainwave frequencies measured by EEG made by San Jose is to _________.80. According to Ware, if you want to throw something such as a truck, you must be __________.81.What is the new idea being studied to develop more challenging and multipurpose games?(Note: Answer the questions or complete the statements in NO MORE THAN ELEVEN WORDS)第II卷(共47分)I.

(17分)当代设计的危机①全球最近似乎迎来了“泛设计”时代,特征之一是领导人和坊问在说发展经济和改善生活的时候,都不约而同言必称“设计”和“创意”,但很奇诡,几乎所有人(包括消费者和设计师)都不满意当下的设计。
市场经济下的设计和消费的“偷安”,使现代设计面临着真正危机。
②该背景下设计的“道德”研究,会是一个十分有意思的角度,“道德”在这里只是一个托词,只是用来涵盖人与人工制造物的所有社会属性和关系。
设计伦理与其他学科的伦理学研究一样,都是关于人的行为的研究。
但是,较之其他学科,设计的道德发生在人与人之间的关系行为似乎均隐现在人与物的关系行为之下,也就是说,口。
那么,在设计伦理学的视野下将如何理解这个“好”呢?③在现代主义设计中,“优良设计”概念的提出和对它的认识,立要集中在对产品功能性的强调和对大众品味的提高上。
其中功能性问题,不仅是围绕实用展开,同时还通过摒弃过分的装饰来实现设计的“挚謇”。
时至今日,由于与经济、与技术、与社会面貌以及文化的反复渗透,设计从边缘进入社会的中心,其重心也从生产转向消费、从需求转向欲求,进商品的周期性推翻沁在不以物品作为实用品的年代>设计的目的必然变得多元范也就变得抽象无约束,像“以人为本”的倡导,曾有设计师以人与规范了产品为人之合理使用的设计底线,然而,这些数据只能解决人的生理需求的愿望,而更高层次的人的欲望需求将如何以“以人为本”的概念得以补充?兰圭盎塑递童兰勺是物品的短失,现在我们痛苦的是物品极大丰富之后的选择以及物的属性的转移。
④鲍德里亚在《消费社会》中对于“物的时代”有过精彩概括,他说:“我们生活在物的时代:我们根据它们的节奏和不断替代的现实而生活着,在以往所有的文明中,能够在一代一代人之后存在下来的是物,是经久不衰的工具或建筑物,而今天,看到物的生产、完善和消亡的却是我们自己。

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)You took a midterm exam(25) (hope) to get a 95 percent. When you got your best paper back, you see you received only a 70 percent. How do you handle the situation? Do you1.make a study plan for(26) (improve) your grade;2.keep doing what you’re doing and hope for the best next time;e a persuasive argument to try and convince your teacher to give you(27) better grade?Your answer to the above question shows your EQ, you emotional intelligence. What exactly is EQ? Psychologists Peter Salovey and John Mayer define it as the ability to understand your own feeling and emotions and(28) of others.Research supports the significance of EQ. A 40-year study of 450 boys found that IQ wasn’t the only thing that affected life success. The qualities that did were ability(29) (handle) frustration, control emotions and get along with other people.Can you improve a low EQ? Yes! Start by noticing how you feel. That’s the first step in becoming more skillful at managing your feelings. Second, pay attention to how you behave when you feel certain emotions.

The salesperson tell you the price,(32) it’s more than you want to pay. What do you do?The answer depends largely on what part of the world you’re in.

The price(34) (list) on a price tag cannot be changed.Large stores and malls usually don’t allow bargaining. On the other hand, outdoor stalls and flea markets, even in Western countries, usually don’t allow bargaining. When in doubt, consult a guidebook or (35) (good)yet, a local friend.(36) bargaining customs vary, a few rules of etiquette apply in most cultures. First, avoid wasting people’s time. If you don’t intend to make a purchase, don’t start bargaining. While bargaining, it is OK to walk away. But once you agree to a price, you(37) buy the item. Even in countries(38) don’t allow bargaining, you may find plentiful opportunities to save money. Many stores sell old items on clearance. Other offer discount cards to regularcustomers.

Gone, for the most part, are the ankle-hugging high-tops that supposedly ___41___ to protect players from injury.The change over the last few years to low-top sneakers(运动鞋) seems to go against conventional wisdom. Strangely, ___42___ , Steven Nash and Kobe Bryant, two of the most ___43___ players with the Los Angeles Lakers, aren’t worried.According to the US market-research firm NPD Groups, high-tops once ___44___ for about 20 percent of the US basketball shoe market. Now, the number has sunk to about 8 percent. Low-tops, the kind that Nash and Bryant wear, have grown to 29 percent, from just 11 percent in 2002.High-top sneakers are one of the most celebrated ___45___ in modern basketball. After the 1985 Air Jordans so transformed the market, show companies began battling one another. They put air pumps in the tongues of their shoes and made carefully prepared and organized ___46___.“All of a sudden it became a ___47___ business,”Marshal Cohen, an analyst with NPD group, told The Wall Street Journal. “The Jordans were excellent. The market went from being nothing to a million-dollar business ___48___.”One of the reasons high-tops are not so ___49___ anymore I sthat they were never really very good at protecting the feet.In an article in the British Journal of Sports Medicine in 2008, University of Newcastle researcher Craig Richards found no evidence that sneakers ___50___ injuries. His research actually found that high-top basketball sneakers could ever cause players to run slower and jump lower. Now the contest has become a war. Companies like Adidas, Nike, Converse and Reebok are all fighting to create the next “air Jordan,” and with the next market battle.Ⅲ. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Are you a graduate trying to plan out the b est career path for yourself? We’ve asked five careers consultants to give some tips on how to go about it.A university degree is no ___51___ of a job, and job hunting in itself requires a whole set ofskills. If you find you are not getting past the first interview, ask yourself what is happening. Is it a(n) ___52___ to communicate or are there some skills you lack? And find out what you need to do to bring yourself up to the level of___53___ that would make you more attractive to them.Do not be too dispirited if you are ___54___ for a job, but think about the reasons the employers give. Those who made the second interview might have been studying the same subject as you and be of ___55___ ability level, but they had something which made them a ___56___ m atch to the selector’s ideal. That could be experience gained through projects or vacation work, or it might be that they were better at communicating what they could offer. Do not take the comments at ___57___ value: think back to the interviews that generated them and make a list of where you think the shortfall in your performance lies. With this sort of analytical approach you will eventually get your foot in the door.Deciding how long you should stay in your first job is a tough call. Stay too long and future employers may question your ___58___ and ambition. Of course, it depends where you are aiming. There can be advantages in moving sideways rather than up, if you want to gain real depth of knowledge. If you are a graduate, spending five or six years in the same job is not too long provided that you take full advantage of the ___59___. However, do not use this as a(n) ___60___ for lacking interest or enthusiasm. Graduates sometimes fail to take ownership of their careers and take the initiative. It is up to you to make the most of what’s available within a company, and to monitor your progress in case you need to ___61___. This applies particularly if you are still not sure where your career path lies.It is helpful to think through what kind of experience you need to get your ___62___ job and it is not a problem to move around to a certain extent. But in the ___63___ stages of your career you need a definite strategy for reaching your goal, so think about that carefully before deciding to move on from your first job. You must cultivate ___64___ to be content for any role. There is no guarantee that you will get adequate training, and research has shown that if you do not receive proper help in a new role, it can take 18 months to ___65___ it.51.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Iceland, an island just south of the Arctic Circle, has fairly mild winters, thanks to warm ocean currents. Time your vacation here during the winter months to take advantage of off-season deals.Off-season means good deals on flights, hotels and tours. You may also find that the locals are a bit f riendlier and more welcoming when tourists aren’t arriving in crowds.In the winter months there are less than seven hours of daylight;thus, chances are good you’ll catch sight of the northern lights. Sunsets are also beautiful ant this time, making for some great photo opportunities.In Iceland, winter is the perfect time to hike glaciers, go ice climbing, explore caves made out of hardened lava(岩浆) and much more. One of the most popular activities is off-roading (越野比赛) in a specially-equipped “super jeep.”Before booking your trip, be sure to check for volcano alerts. There are about 130 volcanoes on or around Iceland. Thirty-five of them are active. In 2010, a volcano named Eyjafjallajokull exploded, sending clouds of ash up to four kilometers in the atmosphere. The ash drifted toward the UK and Europe. Because the ash could damage aircraft engines, airlines operating in the region were forced to cancel flights for six days. As a result, thousands of people were stuck in airports.Recently, another volcano named Bardarbunga has become active, erupting ash into the air. Such events, if large enough could prevent your trip from going ahead. So check the latest volcano news prior to making your reservations.66. According to this article, why are you more likely to see the northern lights in the winter?A. They move from rural areas to cities.B. The weather is more stable at that time.C. They’re a special feature of many festivals.D. The sky is dark for longer periods then.67. According to this article, how do visitors to Iceland have fun in the winter?A. They learn how to ski down the mountains.B. They photograph famous historic sites.C. They explore the countryside in well made vehicles.D. They spend a week at one of the seaside resorts.68. What is true about the volcanoes of Iceland?A. The majority of them are quiet.B. Their age hasn’t bee n determined.C. All but one of them are extinct.D. Citizens aren’t affected by them.69. What does this article explain?A. Some of Iceland’s urban cultural attractions.B. A way to reduce the cost of a trip to Iceland.C. Reasons for visiting Iceland in June and July.D. The average price for a short tour of Iceland.(B)SELF-REFLECTION OF TEACHING PRACTICES READING, WRITING, TALKINGSchool: Date:Grade(s) presently teaching:PLEASE DO NOT SIGN YOUR NAME.

SELF-SELECTION(C)A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science. Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest. The huge amounts of data that are gathered come from many different locations and require special techniques for handling data. Important new tools that facilitate Earth system science include satellite remote sensing, small deep-sea submarines, and geographic information systems.More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts.Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water.Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographicinformation systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of information gathered at different times. For example, satellite remote sensing images of a forest can be converted to represent stages in the forest's growth. Two such images, made at different times can be overlaid and compared, and the changes that have taken place can be represented in a new image.74.

What is the main idea of the passage?A. Special techniques are needed to classify the huge amounts of data about Earth.B. New tools provide information about Earth that was once impossible to obtain.C. Advances in Earth system science have resolved many environmental problems.D. Satellite remote sensing can show changes between two images taken years apart.Section CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.For a glimpse of an evolving technology that promises to shake video gaming to its foundation, check out "Throw Trucks With Your Mind."Unlike most video games, it doesn't rely solely on a mouse or joystick. Instead, its players also don a headset that enables them to hurl trucks or other virtual objects simply by thinking.And that's just for starters. Advocates of so-called neurogaming(交感神经游戏) say the concept in a few years will incorporate a wide array of physiological factors, from a player's heart rate and hand gestures to pupil dilation and emotions. Moreover, they envision many such games being developed to improve the health, brainpower and skills of those playing them.The electroencephalography(脑电波仪), or EEG, headset used to toss trucks and other objects onto adversaries was made by San Jose, Calif.-based NeuroSky. It measures separatebrainwave frequencies that reflect how focused the player is and how calm they are, according to Lat Ware of Emeryville, Calif., who developed the game and is the founder of Crooked Tree Studios. The game, which can be purchased at , costs $25, or $99 with the headset.Ware, 29, said it's possible to move a pear or other small virtual object if the player is calm, but not focused, or vice versa. But he said both mental states are essential to flatten a foe with a hurled monster truck, which takes considerable concentration.Although only a few neurogames have been introduced so far and their action tends to be fairly limited, the games are expected to become far more challenging - and multipurpose - as the software and related technology improves.One concept being explored is to develop games that adjust their action according to the player's changing emotions, as measured by such factors as their facial expressions, eye movement and skin-conductance(皮肤导电)levels. Another approach is to make games that influence how the player thinks and feels.Consider Los Angeles-based Melon, which, like "Throw Trucks With Your Mind," was recently launched via the online fundraising site Kickstarter. Melon officials say their first game - which challenges players to fold origami(折纸)with their mind, using NeuroSky's EEG headset - helps people "learn how to focus, relax and meditate better."(Note: Answer the questions or complete the statements in NO MORE THAN ELEVEN WORDS.)78.
