How to Make Attractive and Effective PowerPoint PresentationsA． Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive Power-Point presentations.The TextB． Keep the wording clear and simple. Use active, visual language. Cut unnecessary words--a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into keywords. Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide,use the Auto Fit feature to split it between two slides. Click within the placeholder to display the Auto Fit Options button (its symbol is two horizontallines with arrows above and below., then click on the button and choose Split Text between Two Slides from the submenu.C． Font size for titles should be at least 36 to 40, while the text body should not be smaller than 24.Use only two font styles per slide--one for the title and the other for the text. Choose twofonts that visually contrast with each other. Garamond Medium Condensed and impact are good for titles, while Garamond or Tempus Sans can be used for thetext body.D． Embed the fonts in your presentation, ifyou are not sure whether the fonts used in the presentation are present in thecomputer that will be used for the presentation. To embed the fonts: ( 1 )Onthe File menu, click Save As.(2) On the toolbar, click Tools, click Save Options, select the Embed True Type Fonts check box, and then select Embed characters in use only.E． Use colors sparingly; two to three atmost. You may use one color for all the titles and another for the text body.Be consistent from slide to slide. Choose a font color that contrasts well withthe background.F． Capitalizing the first letter of eachword is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters meansyou are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. ClickingShift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G) Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation. Don't center bulleted lists or text. It is confusing to read. Left align unless you have agood reason not to. Run "spell check" on your show when finished.The BackgroundH) Keep the background consistent. Simple,light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored background and use any light color for text.Minimize the use of "bells and whistles" such as sound effects,"flying words" and multiple transitions. Don't use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.The ClipsI) Animations are best used subtly; too much flash and motion can distract and annoy viewers( Do not rely too heavily on those images that were originally loaded on your computer with the rest of Office. You can easily find appropriate clips on any topic through Google images. While searching for images, do not use long search phrases as isusually done while searching the web-use specific words.J) When importing pictures, make sure that they are smaller than two megabytes and are in a jpg format. Larger files can slow down your show. Keep graphs, charts and diagrams simple, if possible. Use bar graphs and pie charts instead of tables of data. The audience can then immediately pick up the relationships.The PresentationK) If you want your presentation todirectly open in the slide show view, save it as a slide show file using the following steps. Open the presentation you want to save as a slide show. On the File menu, click Save As. In the Save as type list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-clickon this file, it will automatically start your presentation in slide show view.When you're done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides,whenever possible. If using a laser pointer, don't move it too fast. For example, if circling a number on the slide, do it slowly. Never point the laser at the audience. Black out the screen (use "B" on the keyboard) after the point has been made, to put the focus on you. Press the key again to continue your presentation.M) You can use the shortcut command [Ctrl]P to access the Pen tool during a slide show. Click with your mouse and drag to use the Pen tool to draw during your slide show. To erase every-thing you've drawn, press the E key. To turn off the Pen tool, press [Esc] once.MiscellaneousN) Master Slide Set-Up: The "master slide" will allow you to make changes that are reflected on every slide in your presentation. You can change fonts, colors, backgrounds, headers, and footers at the "master slide" level. First, go to the"View" menu. Pull down the "Master" menu. Select the" slide master" menu. You may now make changes at this level that meet your present ation needs. 答案解析
The Technology Makes ScentsA) "Memories, imagination, old sentiments, and associations are more readily reached through the sense of smell than through any other channel," said the 19th-century physician, poet and Harvard professor, Oliver Wendell Holmes. No wonder, then, that technologists have long sought a way to transmit smell electronically. Imagine being able to send from your phone not just a photo but the aroma( 芳香) of freshly mown grass, the scents of an exotic spice market or of a brand new perfume, and know that the recipient would instantly experience it. "Smell-and taste too-are going to be the next important dimensions for communicating by computer," says Adrian Cheok, professor of pervasive computing at City University in London. "They are the only senses connected with the limbic system(边缘系统）in the brain, which is responsible for emotion and memory. But it's difficult to transmit smell because it's analogue(模拟的). It's like sound before MP3. " B) The 42-year-old Australian electrical engineer is dedicated to bringing all five senses into communication and has a nose for(对敏感) commercial potential. His team's first smart phone smell product, Scentee, made by a Japanese company, is already selling 10,000 $ 30 units a month in Japan,traditionally the most receptive first market for eccentric technology products. It may soon make in-roads in the US. Bacon company Oscar Meyer earlier this year offered as competition prizes 1,000Scentees. The idea? For winners to programme their iPhone alarm to wake them with the aroma offrying bacon. Other innovators are working in this area too. Israeli inventor Amos Porat claims tohave shown a prototype of his digital smell dispenser, Scentasia, to enthusiastic toy manufacturers inthe US. Scentee is analogue in that it is chemical-based. It resembles a pipe bowl that connects to theheadphone socket of an iPhone 5 and, when triggered by text or alarm, emits a puff of, typically,bacon, coffee or lavender. Scentee can produce only one smell at a time, so the recipient has to havethe right cartridge (套筒) fitted to get the olfactory (嗅觉的) message as intended. But on ProfCheok's lab bench is the next prototype, which can produce 10 smell combinations. C) "Once these technologies come together, we'll have high-fidelity capture and transmission of smell,"Prof Cheok says, speaking in a workshop full of electronic components and soldering irons. "Therewill be something like an ink-jet printer, with maybe 100 valves in a unit and real time combinationsto create many smells. " While this is theoretically possible, he admits he has not actually done it yet.D) Corporate researchers are also looking into this area, however. Prof Cheok produces from his book-shelf a 2013 academic paper showing that this field may already be beyond the merely strange. It isentitled "Development of Highly Sensitive Compact Chemical Sensor System Employing a Microcantilever Array and a Thermal Preconcentrator". Its authors include someone from Olympus in Japan.E) But how convincing is the existing City University kit? Prof Cheok demonstrates some smells createdand bottled by the renowned Mugaritz restaurant in northern Spain, which is working with his depart-ment on smell transmission. For a restaurant, transmitting smell by Internet could be a great publicitytool. The first Mugadtz aroma, of sesame, is easy to recognise. The second, which I fail to guess,is saffron. The third, which I get with prompting, is black pepper.F) Prof Cheok's department is already working on the next level for smell transmission, which is wherethe technology goes from being partly analogue to wholly digital. "So the issue becomes, can we getaway from the chemicals by stimulating smell and taste with electrical or magnetic signals?"G) Prof Cheok produces a crude device that electronically creates artificial taste in the brain. It is a rawcircuit board with a metal part sticking out. He asks me to put my tongue on this, promising it hasbeen cleaned with alcohol. An assistant clicks on her laptop and I get a distinctly sour sensation.Sweet, salty and bitter, he says, are in development. For electronic smell, the department is collabo-rating with a neuroscience lab in France specialising in "emotional perception". "The olfactory bulb(嗅球) is harder to access than the tongue, buried behind the nose, so probes would be painful," heexplains. "So the idea might, be a small magnetic coil in the mouth and a pulsed magnetic field thatwill generate currents in the olfactory bulb. It could take the form of a mouth guard kind of thing. "He suggests making food taste salty by embedding a taste probe on to your fork and knife. H) Prof Cheok envisages electronic taste transmission might lead to the development of "digital food",he says, "People will transmit a flavour over the internet. " As with digital music, people will be a-ble to use the technology to invent new flavours. "It won't just lead to reproduction of coffee orwhatever, but we will digitally invent completely new kinds of food based on digital smell andtaste. "I) A full professor at 36, Prof Cheok's accessible TED-talk manner, along with the proven demand in its test market for Scentee, gives even his arguably more left field predictions a whiff of plausibility. Af- ter all, if there is one constant that perhaps explains why some sceptically received inventions succeed where others fail, it is that they appeal to basic human emotion and the desire to communicate.J) Lest any bodily sense should feel left out, Prof Cheok then turns to communicating touch by comput- er, an idea that was being discussed 30 years ago when virtual reality was in vogue. Except, as with Scentee, Prof Cheok and his disciples have already been there and sold the T-shirt, so to speak. James Teh, a former PhD student, has spun off a Singapore company, www. mytjacket, tom, making re- motely controlled "hugging jackets" for autistic children( 自闭症儿童), who are especially receptive to a hug, even if it is delivered by a parent thousands of miles away from his phone. It is impossible, of course, to predict if any of Prof Cheok and his team's inventions will take off. However, with their focused attention to those all important human emotions, and the raw evocative(唤起的）power of smell in particular, it is hard not to feel they are in fertile territory. 答案解析

Rock and roll is a genre of popular music that evolved in theUnited Statesin the late 1940s and early 1950s. Its 1 lie mainly in blues, rhythm and blues, country, folk, gospel, and jazz. The style subsequently spread to the rest of the world and developed further, leading ultimately to 2 rock music.　　The term “rock and roll” now covers at least two different meanings, both in common usage. The American Heritage Dictionary and the Merriam-Webster Dictionary both 3 rock and roll as synonymous with rock music.　　4 , Allwords.com defines the term as referring specifically to the music of the 1950s.　　Classic rock and roll is 5 played with one or two electric guitars, a string bass or an electric bass guitar, and a drum kit. In the 6rock and roll styles of the late 1940s, either the piano or saxophone was often the lead instrument, but these were generally 7 or supplemented by the guitar in the middle to late 1950s.　　The massive popularity and eventual worldwide view of rock and roll gave it a 8 social impact. Far beyond simply a musical style, rock and roll, as seen in movies and in the new medium of television, 9 lifestyles, fashion, attitudes, and language. It went on to spawn various sub-genres, often without the initially 10 backbeat, that are now more commonly called simply “rock music” or “rock”.A. define B. characteristicC. uniqueD. rootsE. usuallyF.

Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can __1__ performance at work and school. Cognitive( 认识派的 ) researchers, who study various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on __2__ and gifts from others. 　　The latter view has gained many supporters, __3__ among educators. But the careful use of small __4__ rewards speaks creativity in grade school children, suggesting that properly presented inducements(刺激) indeed __5__inventiveness, according to a study in the June Journal of Personality and Social Psychology. 　　“If kids know they’re working for a reward and can focus on a relatively __6__ task, they show the most creativity,” says Robert Eisenberger of the University of Delaware in Newark. “But it’s easy to __7__ creativity by giving rewards for poor performance or creating too much anticipation for rewards. 　　A teacher who continually draws attention to rewards or who hands our high grades for __8__ achievement ends uPwith uninspired students, Eisenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and __9__ failing grades. 　　In early grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points to ward valued rewards, shows __10__ in raising efforts and creativity, the Delaware psychologist claims.

As is known to all, the organization and management of wages and salaries are very complex. Generally speaking, the Accounts Department is __1__ for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay. 　　If a firm wants to __2__ a new wage and salary structure, it is essential that the firm should decide on a __3__ of job evaluation and ways of measuring the performance of its employees. In order to be __4__, that new pay structure will need agreement between Trade Unions and employers. In job evaluation, all of the requirements of each job are defined in a detailed job description. Each of thsoe requirements is given a value, usually in "points", which are __5__ together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their __6__ to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without __7__ to an evaluation system based on points. 　　In attempting to design a pay system, the Personnel Department should __8__ the value of each job with these in the job market. __9__, payment for a job should vary with any differences in the way that the job is performed. Where it is simple to measure the work done, as in the works done with hands, monetary encouragement schemes are often chosen, for __10__ workers, where measurement is difficult, methods of additional payments are employed.

In families with two working parents, fathers may have more impact on a child's language development than mothers, a new study suggests. Researchers __1__ 92 families from 11 child care centers before their children were a year old, interviewing each to establish income, level of education and child care arrangements. Overall, it was a group of well-educated middle-class families, with married parents both living in the home. When the children were 2, researchers videotaped them at home in free-play sessions with both parents, __2__ all of their speech. The study will appear in the November issue of The Journal of Applied Development of Psychology. The scientists measured the __3__ number of utterances (话语) of the parents, the number of diffe-rent words they used, the complexity of their sentences and other __4__ of their speech. On average, fathers spoke less than mothers did, but they did not differ in the length of utterances or proportion of questions asked. Finally, the researchers __5__ the children's speech at age 3, using a standardized language test. The only predictors of high scores on the test were the mother's level of education, the __6__ of child care and the number of different words the father used. The researchers are __7__ why the father's speech, and not the mother's, had an effect.
