Look After Your VoiceOften speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth.First gently bite the edges of your tongue with your teeth.Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can imagine that you are slicing a big juicy lemon and sucking the juice.Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that you are losing your voice,stop talking completely.Save your voice for your speech.Youmay feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to see a doctor.perhaps you can get some advice from a orofessional singer. In the meantime,do not even talk ina low voice.What about drinking alcohol to wet your throat?I advise you not to touch alcohol before speaking.The problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain and your mouth do not work together properly.Save the alcohol until after you finish speaking.Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop your new habits.If you are willing to change,you will soon be able. to say that you will never forget these techniques because they became a part of your body.The writer cites Goethe to prove that one can change one's habits.A:RightB:WrongC:Not mentioned

Natural Gas1 Natural gas is produced from reservoirs deep beneath the earth's surface. It is a fossil fuel（矿物燃 料）,meaning that it is derived from orgaiiic material buried in the earth millions of years ago.The main corn- ponent of natural gas is methane（甲烷）.2 The popularity and use of clean natural gas have increased dramatically over the past 50 years as pipeline infrastructure（基础设施）has been installed to deliver it conveniently and economically to millions of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50 states in the U.S.,and is the leading energy choice for fueling American homes and industries.More than 65 million American homes use natural gas.In fact,natural gas is the most economical source for home energyneeds,costing one-third as much as electricity.In addition to heating homes,much of the gas used in the United States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to plastics for healthcare,computing and furnishings.Natural gas is also used in a significant number of new electricity-generating power plants.3 Natural gas is one of the safest and cleanest fuels available. It emits（发出）less pollution than other fossil fuel sources. When natural gas is burned , it produces mostly carbon dioxide（二氧化碳）and water va- por一the same substances emitted when humans breathe.Compared with some other fossil fuels,natural gas emits the least amount of carbon dioxide into the air when combusted（燃烧）一making natural gas the clea-nest burning fossil fuel of all.4 The United States consumes about one一third of the world's natural gas output,making it the largest gas-consuming region in the world.The U.S.Department of Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025.5 There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natural gas can be found in Russia , West and North Africa and the Middle East. LNG（液化天然气）has been pro- duced domestically and imported in the United States for more than four decades.Today,the leading import- ers of LNG are Japan,Korea,France and Spain.Paragraph 3__________A:Popularity and Use of Natural GasB:Natural Gas Reserves and SupplyC:Natural Gas PricesD:Clean Fuel of ChoiceE:Disadvantages of Natural GasF:Natural Gas Consumption

第二篇A Four-day WeekFancy a three-day weekend一not just once in a while but week in week out? You may think your bosses would never agree to it,but the evidence suggests that employers,employees and the environment all benefit.The four-day week comes in two flavors.One option is to switch from five 8-hour days to four 10-hour days,meaning overall hours and salaries stay the same.Two years age,the state of Utah moved all of its employees,apart from the emergency services,to working 4/10,as it has become known.The hope was that by shutting down buildings for an extra day each week,energy bills would be cut by up to a fifth.The full results of this experiment won't be published until October,but an ongoing survey of 100 buildings suggests energy consumption has fallen by around 13 percent. The survey also found that 70 percent of employees prefer the 4/10 arrangement,and that people look fewer days off sick.The second form of the four-day week is to work the same number of hours per day for four days only,with a 20 percent pay cut. With the recession hutting revenues , accountancy（会计工作） company KPMG announced in February that it was offering its 11,000 U.K. employees the option of a four-day week to avoid job losses.So far 85 percent of employees have applied to join the scheme, and 800 now do a four-day week.Not everyone will like the idea of working longer days or taking a pay cut in exchange for a 3-day weekend,but it appears most do.According to Rex Facer at Brigham Young University in Provo,Utah,it was the crash of 1929 that led to the five-day week.During the next big financial crisis in the 1970s,there was much talk of moving to a four-day week,but for a variety of reasons that didn't pan out."Things are different now,"says Facer."I wouldn't be surprised if we could get 50 percent or more of the workforce working four-day weeks in the next few years."An ongoing survey shows that_______.A:employers benefit a lot from the four-day schedule B:energy use has decreased by 13%in UtahC:most employees approve of the 4/10 scheduleD:employees work much more efficiently

Ever wondered how your cat or dog sees the world?Now you can look through their eyes with the first 3 D game that recreates the vision of different species based on scientific evidence.
The online simulation,created by the French 3 D design company Dassault Systemes,with the guidance of veterinary ophthalmologist（眼科专家）Didier Schmidt-Morand , mimics（模仿）the vision of five animals-cats,dogs,rats,hawks and bees-as a player steers them through Place in Paris.
Due to differences in field of view,colour perception and night vision,for example,sight can be drastically different from species to species.In terms of performance,eyes are as variable as different models of cars,says Schmidt-Morand.
The game was created by using existing virtual models of the square then applying effects based on descriptions of each animals vision.Dassaults 3 D software allows a scene to be modified by adding blur or changing the colours,angle of vision and depth of field.
Although it was easy to recreate vision inferior to that of humans-cats and dogs,for example,have trouble distinguishing shades of red-replicating features that we are unable to see was a challenge.Hawks have more detailed vision than ours,whereas dogs are better at seeing movement and have a wider field of
view.We used virtual cameras to precisely simulate larger viewing angles but the result made people nauseous（令人作呕的）,says Schmidt-Morand.So we tweaked（微调）the model to give a sense of the wider view without sticking to reality.
The rats view also departs from reality:because they are near-sighted,everything more than 15 centimetres away is a blur,so they typically move close to walls to help them navigate.A rat would never throw itself into the middle of an open area,says Schmidt-Morand.The simulation for this animal is supplemented with a map in the top right corner to help determine the rats position:because of their limited eyesight,most landmarks are obscured.
The game is intended as an educational resource and players can discuss their experience with others through community features on the website.If there is interest from schools and zoos,the team hopes to recreate the vision of more animals.The team is working on recreating the vision of more animals.A:Right B:Wrong C:Not mentioned
