◆According to expertsthe advantage of modified food is that it helps in preventing the occurrence of allergies and also has along shelf lifeHowevera major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantagesIf you are also confused about the consumption of genetically modified foodread through the pros and cons given below and decide for yourself
Advantages of Genetically Modified Foods
●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseasesCertain foods cause allergy to peopleTheir genetic modification alters the DNA system of these foodsthereby making them nonallergic
●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterpartsAs a resultthere is greater productivity and more food
●A person need not bother about any additional costssuch as buying chemicals and pesticideswhen it comes to genetically engineered foodThe food is naturally pestresistant
●Farming these foods can be a great way to fight world hungerSince these crops grow faster or more effectivelyincreased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions
●The increased shelf life of these food products helps in reducing the quantity of rotten food
Disadvantages of Genetically Modified Foods
●The biggest disadvantage of genetically modified food is that they have harmful effects on the human bodyThe consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics
●Chances of developing cancer are high in people who regularly consume engineered food
●Since it is an unnatural way of producing foodsthere is an increased health hazard such as allergenstransfer of antibiotic resistance markers and unknown effects
●Since the production of engineered food involves infusing animal genes in the crops and tampering with natureit might not be good for consumption in the long run

◆Baidu China’s leading search engine company has unveiled its own eyewear called Baidu Eye It is said to be a different product from Google Glass in terms of functionality
The company demonstrated a working prototype on September 3 at its annual Technology Innovation
Conference in Beijing It bears a similarity to Google Glass but it has no screen Instead the device uses a
camera to scan objects and focuses on analyzing information around its user and beaming that to a
smartphone
Baidu says the device is designed to support image search The company’s CEO Robin Li believes in
five years’ time people will get used to searching by image and audio rather than text Li has given an
example of how one can take advantage of Baidu Eye If you are in a shopping mall and come across a
woman whose skirt looks really attractive you take a photo of her skirt using Baidu Eye and you’ll get to
know where to buy one for yourself
According to Kaiser Kuo Baidu’s director of international communications Baidu Eye can also
recognize voice and gesture You can use voice commands or gesture commands—like expanding to zoom
or circling an object in your field of view with your finger
Baidu is yet to announce a release date or marketing plans for Baidu Eye

◆Imagine you sitting on your front garden admiring the shining sun when your neighbor comes with that annoying car with the noisy sound and the exhaust pipe blowing out the horrible black smokeWhat are you going to do about it？
In our modem daystoo many people depend on their cars to get to work or to drop off their children to schoolHoweveris it safe to have an increasing number of cars on our roads？Research shows that cars create serious pollutionExhaust from all combustion engines produce harmful effects on the health of both car users and all innocent walkersCities have become islands of toxic chemicals from the unrestrained use of vehicles burning fossil fuelsThe harmful health effects of car exhaust are pervasive and difficult to measureFor examplepeople with asthma would suffer with attacks due to the pollutionThe world wild life also suffers from the cars’ toxic emissionsNo matter how much manufacturers try to make cars environmentally friendly it will damage our earth in one way or another
Additionally cars are too dangerous for our communityCareless drivers put themselves and others in dangerCars are critical to walkers especially to children if the driver is not looking on the road or somehow distracted Have you known someone whose toes or fe

◆When computer servers operate a complex programthey can get very hotCooling the servers can be costlySo researchers asked what would happen if the heat created by the servers could be captured and used
Data centers of large Internet companies such as Google and Microsoft have thousands of computer serversAs these servers process informationthey create large amounts of heatso they need huge cooling systemsThese systems send the heat into the air
The Dutch company Nerdalize thinks paying for electrieity to operate the servers and then paying again to cool them is a waste of energySo it developed a device called the eRadiatorIt is a computer server that also works as a heating sourceBoaz Leupe is the chief executive officer of NerdalizeHe says the eRadiator saves money because companies don’t have to pay to cool their servers
The kilowatt(千瓦) hour you are using is used twiceonce to heat the home and once to compute the client’s task without the cooling overheadHe says five homeowners in the Netherlands are testing the heating device in their homesWe reimburse the electricity the server usesand that we can do because of the computer clients on the other sideandin that wayhomeowners actually get heating for freeand computer users don’t have to pay for the overhead of the data center
Jan Visser is one of the participants in the yearlong experimentHe says the amount of heat produced by the eRadiator into room depends on the work being done by the computer serverHe says it can not be used as the primary source of heatBut he is ready to try it
He says if it provides enough warmthhe will be able to use his home’s heating system lesswhich will save him moneyNerdalize says eRadiators create heat temperatures of up to 55℃It says the devices could save users up to 440 in heating costs a year

◆WHY BUILD A SPACE ELEVATOR
The space elevator will reduce the cost of getting from Earth to space It will also allow us to take very large payloads into space very easily very safely Because of that we can build cities on the moon We can build space stations We can build large solar arrays in space to collect energy from the sun and beam it down to Earth
WHY NOT JUST USE ROCKETS INSTEAD
Rockets are very expensive The shuttle costs S10000 a pound to put a payload into lowEarth orbit and if you want to go to the moon or Mars it’s hundreds of thousands of dollars per pound or more Rockets are also very limited in the amount of payload they can carry and they’re risky With a space elevator the cost is a fraction of thatit may go down to 100th or 1000th of current costsand there are no rocket engines that might explode
WHAT WOULD IT BE LIKE TO RIDE THE ELEVATOR
You’d go to an ocean platform you’d climb into a module and you’d feel it start moving You’d see the Earth fall away In just a half hour or so you’d pass up through the clouds and you’d start to see the curve of the horizon Another half an hour to an hour later you’d basically be in space You’d see stars even in the middle of the day Eventually you’d be weightless It’d be a very smooth ride there wouldn’t be any shaking
ARE THERE POTENTIAL DRAWBACKS TO OPENING SPACE THIS WAY
Everything we do has the potential for creating some bad If we mine an asteroid the asteroid’s going to look ugly just like a mine here But I think the benefits of opening up space far outweigh the damage that we can seebenefits in terms of gaining energy from space to replace oil additional capabilities in telecommunications manufacturing in space additional real estate and exploration

◆Would a robot serving you coffee in bed make waking up easier on weekday mornings Could a household robot help an elderly relative who is living alone How would you like to climb into a robotic car and eat breakfast with the kids while you’re all driven to school and work
These scenarios may sound like science fictionbut experts say they’re a lot closer to becoming reality than you probably think
Brown University roboticist Chad Jenkins expects a nearterm robot revolution that will echo the computing revolution of recent decadesAnd he says it will be driven by enabling robots to learn more like humans doby watching others demonstrate behaviors and by asking questions
The robots you’re seeing now mostly are analogous to the mainframe computers of the 1970sJenkins saidBut you’re starting to see things developThe vacuum cleanersthe dronesthose are the initial stepshe saidreferring to iRobot’s Roomba vacuum cleanerwhich has autonomously cleaned millions of homes since its 2002 debut
And these platforms are going to get cheaper while becoming more capable and more compacthe added
And entrepreneurs like Dmitry Grishinfounder of a major Russian Investment firm dedicated to personal roboticshave taken noticeHe says the industry could be worth 18 billion by 2015
But to really transformroboticists sayrobots will have to evolve from machines that can perform only the tasks they’re programmed to do into automatons that can truly learnThat’s because it’s impossible to preprogram a robot for everything it will encounter in the everchanging real world
If you look at where robots are successful right nowit’s primarily in applications where the environment is very controlledlike an assembly line where everything is the sameor in the hands of experts with PhDswhere we see them on Mars said Chernova
To really get them to handle the complexities of our real worldshe said they are going to have to be customized onsiteIt’s not going to happen tomorrowbut it’s very close
Such a leap could help bring robots into the mainstream

◆According to expertsthe advantage of modified food is that it helps in preventing the occurrence of allergies and also has along shelf lifeHowevera major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantagesIf you are also confused about the consumption of genetically modified foodread through the pros and cons given below and decide for yourself
Advantages of Genetically Modified Foods
●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseasesCertain foods cause allergy to peopleTheir genetic modification alters the DNA system of these foodsthereby making them nonallergic
●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterpartsAs a resultthere is greater productivity and more food
●A person need not bother about any additional costssuch as buying chemicals and pesticideswhen it comes to genetically engineered foodThe food is naturally pestresistant
●Farming these foods can be a great way to fight world hungerSince these crops grow faster or more effectivelyincreased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions
●The increased shelf life of these food products helps in reducing the quantity of rotten food
Disadvantages of Genetically Modified Foods
●The biggest disadvantage of genetically modified food is that they have harmful effects on the human bodyThe consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics
●Chances of developing cancer are high in people who regularly consume engineered food
●Since it is an unnatural way of producing foodsthere is an increased health hazard such as allergenstransfer of antibiotic resistance markers and unknown effects
●Since the production of engineered food involves infusing animal genes in the crops and tampering with natureit might not be good for consumption in the long run

◆Baidu China’s leading search engine company has unveiled its own eyewear called Baidu Eye It is said to be a different product from Google Glass in terms of functionality
The company demonstrated a working prototype on September 3 at its annual Technology Innovation
Conference in Beijing It bears a similarity to Google Glass but it has no screen Instead the device uses a
camera to scan objects and focuses on analyzing information around its user and beaming that to a
smartphone
Baidu says the device is designed to support image search The company’s CEO Robin Li believes in
five years’ time people will get used to searching by image and audio rather than text Li has given an
example of how one can take advantage of Baidu Eye If you are in a shopping mall and come across a
woman whose skirt looks really attractive you take a photo of her skirt using Baidu Eye and you’ll get to
know where to buy one for yourself
According to Kaiser Kuo Baidu’s director of international communications Baidu Eye can also
recognize voice and gesture You can use voice commands or gesture commands—like expanding to zoom
or circling an object in your field of view with your finger
Baidu is yet to announce a release date or marketing plans for Baidu Eye

◆Imagine you sitting on your front garden admiring the shining sun when your neighbor comes with that annoying car with the noisy sound and the exhaust pipe blowing out the horrible black smokeWhat are you going to do about it？
In our modem daystoo many people depend on their cars to get to work or to drop off their children to schoolHoweveris it safe to have an increasing number of cars on our roads？Research shows that cars create serious pollutionExhaust from all combustion engines produce harmful effects on the health of both car users and all innocent walkersCities have become islands of toxic chemicals from the unrestrained use of vehicles burning fossil fuelsThe harmful health effects of car exhaust are pervasive and difficult to measureFor examplepeople with asthma would suffer with attacks due to the pollutionThe world wild life also suffers from the cars’ toxic emissionsNo matter how much manufacturers try to make cars environmentally friendly it will damage our earth in one way or another

◆When computer servers operate a complex programthey can get very hotCooling the servers can be costlySo researchers asked what would happen if the heat created by the servers could be captured and used
Data centers of large Internet companies such as Google and Microsoft have thousands of computer serversAs these servers process informationthey create large amounts of heatso they need huge cooling systemsThese systems send the heat into the air
The Dutch company Nerdalize thinks paying for electrieity to operate the servers and then paying again to cool them is a waste of energySo it developed a device called the eRadiatorIt is a computer server that also works as a heating sourceBoaz Leupe is the chief executive officer of NerdalizeHe says the eRadiator saves money because companies don’t have to pay to cool their servers
The kilowatt(千瓦) hour you are using is used twiceonce to heat the home and once to compute the client’s task without the cooling overheadHe says five homeowners in the Netherlands are testing the heating device in their homesWe reimburse the electricity the server usesand that we can do because of the computer clients on the other sideandin that wayhomeowners actually get heating for freeand computer users don’t have to pay for the overhead of the data center
Jan Visser is one of the participants in the yearlong experimentHe says the amount of heat produced by the eRadiator into room depends on the work being done by the computer serverHe says it can not be used as the primary source of heatBut he is ready to try it
He says if it provides enough warmthhe will be able to use his home’s heating system lesswhich will save him moneyNerdalize says eRadiators create heat temperatures of up to 55℃It says the devices could save users up to 440 in heating costs a year

◆WHY BUILD A SPACE ELEVATOR
The space elevator will reduce the cost of getting from Earth to space It will also allow us to take very large payloads into space very easily very safely Because of that we can build cities on the moon We can build space stations We can build large solar arrays in space to collect energy from the sun and beam it down to Earth
WHY NOT JUST USE ROCKETS INSTEAD
Rockets are very expensive The shuttle costs S10000 a pound to put a payload into lowEarth orbit and if you want to go to the moon or Mars it’s hundreds of thousands of dollars per pound or more Rockets are also very limited in the amount of payload they can carry and they’re risky With a space elevator the cost is a fraction of thatit may go down to 100th or 1000th of current costsand there are no rocket engines that might explode
WHAT WOULD IT BE LIKE TO RIDE THE ELEVATOR
You’d go to an ocean platform you’d climb into a module and you’d feel it start moving You’d see the Earth fall away In just a half hour or so you’d pass up through the clouds and you’d start to see the curve of the horizon Another half an hour to an hour later you’d basically be in space You’d see stars even in the middle of the day Eventually you’d be weightless It’d be a very smooth ride there wouldn’t be any shaking
ARE THERE POTENTIAL DRAWBACKS TO OPENING SPACE THIS WAY
Everything we do has the potential for creating some bad If we mine an asteroid the asteroid’s going to look ugly just like a mine here But I think the benefits of opening up space far outweigh the damage that we can seebenefits in terms of gaining energy from space to replace oil additional capabilities in telecommunications manufacturing in space additional real estate and exploration

[单选题]◆Which of the following statements is NOT correct when you are riding the space elevator
You can’t see the stars in the middle of the day
◆Would a robot serving you coffee in bed make waking up easier on weekday mornings Could a household robot help an elderly relative who is living alone How would you like to climb into a robotic car and eat breakfast with the kids while you’re all driven to school and work
These scenarios may sound like science fictionbut experts say they’re a lot closer to becoming reality than you probably think
Brown University roboticist Chad Jenkins expects a nearterm robot revolution that will echo the computing revolution of recent decadesAnd he says it will be driven by enabling robots to learn more like humans doby watching others demonstrate behaviors and by asking questions
The robots you’re seeing now mostly are analogous to the mainframe computers of the 1970sJenkins saidBut you’re starting to see things developThe vacuum cleanersthe dronesthose are the initial stepshe saidreferring to iRobot’s Roomba vacuum cleanerwhich has autonomously cleaned millions of homes since its 2002 debut
And these platforms are going to get cheaper while becoming more capable and more compacthe added
And entrepreneurs like Dmitry Grishinfounder of a major Russian Investment firm dedicated to personal roboticshave taken noticeHe says the industry could be worth 18 billion by 2015
But to really transformroboticists sayrobots will have to evolve from machines that can perform only the tasks they’re programmed to do into automatons that can truly learnThat’s because it’s impossible to preprogram a robot for everything it will encounter in the everchanging real world
If you look at where robots are successful right nowit’s primarily in applications where the environment is very controlledlike an assembly line where everything is the sameor in the hands of experts with PhDswhere we see them on Mars said Chernova
To really get them to handle the complexities of our real worldshe said they are going to have to be customized onsiteIt’s not going to happen tomorrowbut it’s very close
Such a leap could help bring robots into the mainstream
