11．Jimmy is an automotive mechanic，but he lost his job a few months ago．He has good heart，but always feared applying for a new job．
One day，he gathered up all his strength and decided to attend a job interview．His appointment was at 10am and it was already 8：30．While waiting for a bus to the office where he was supposed to be interviewed，he saw an elderly man wildly kicking the tire of his car．Obviously there was something wrong with the car．Jimmy immediately went up to lend him a hand．When Jimmy finished working on the car，the old man asked him how much he should pay for the service．Jimmy said there was no need to pay him； he just helped someone in need，and he had to rush for an interview．Then the old man said，"Well，I could take you to the office for your interview．It's the least I could do．Please．I insist．"Jimmy agreed．
Upon arrival，Jimmy found a long line of applicants waiting to be interviewed．Jimmy still had some grease on him after the car repair，but he did not have much time to wash it off or have a change of shirt．One by one，the applicants left the interviewer's office with disappointed look on their faces．Finally his name was called．The interviewer was sitting on a large chair facing the office window．Rocking the chair back and forth，he asked，"Do you really need to be interviewed？"Jimmy's heart sank．"With the way I look now，how could I possibly pass this interview？"he thought to himself．

"Sorry I had to keep you waiting，but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office．I just know you'd be a trustworthy worker．Congratulations!"Jimmy sat down and they shared a cup of well-deserved coffee as he landed himself a new job．

9．Working outside the International Space Station （ISS），an astronaut is suddenly hit by a piece of space debris（碎片）that damages his spacesuit．Alarmed，he realizes he's just seconds from disaster．Moving fast，his prepared robot partner slaps（拍打）an auto-patch over the tear in his spacesuit．Huge sighs of relief fill the ISS．Inside，the astronaut responsible for saving the spacewalker's life controls everything the robot avatar has done-including rescuing its human partner-while it works outside the space station．
R2：The Real Deal
A robot companion can come in handy to space travelers，whether they're as far away as Mars or as close as a space station or moon base．Space-travelling avatars，controlled remotely by humans are still a concept．But earlier in the year 2011，NASA sent a humanoid robot into space for the first time．It's called R2，short for Robonaut 2．The robot was delivered by the space shuttle Discovery and will remain on the ISS to be tested．
NASA expects robots like R2 to be a huge help to astronauts．"Our goal is for robots to work side by side with humans，"says NASA's Matt Ondler．R2 is controlled by humans using laptops． It's programmed to perform a number of small tasks，such as"find an object．"In most situations，humans are still far better with their hands than robots．But that's not necessarily true in space，where astronauts must wear bulky spacesuits and heavy gloves．And since they don't need to eat，breathe，or go to the bathroom，robonauts have the advantage for lengthy jobs．
R2 isn't ready for spacewalks yet，but NASA hopes that future improvements will make this possible．"Robonauts will help our astronauts with the three D's：jobs that are dirty，dull，and dangerous，"says Ondler．
To The Moon
Someday the space agency hopes to send R2 to the moon．Sending a robot to the moon will befar less expensive than sending a human．A robot is stronger，can survive in tighter spaces，and doesn't need air．Even better，robots don't care how long it takes for NASA to return them to Earth．
Once on the moon，the robonaut could perform experiments，send live video back to Earth，talk to classrooms full of kids，and explore the lunar surface．R2 will be able to move using legs，or by attaching its torso（躯干）to a four-wheeled rover（探测器） and becoming part of vehicle．And when R2's battery is low，it can plug into a solar-powered recharging station and get some much-needed juice．All in all，a pretty sweet life for a humble robot!
The future R2 would be designed to operate by itself．But for difficult tasks，a human operator would control it like an avatar in a video game．NASA will need people skilled at operating robonauts to ensure the success of future missions．So the next time your mom complains that you're spending too much time on video games，just tell her you're training for a job with NASA．
