A．has heldB．has been heldC．will be heldD．had been held

分析 到目前為止，這是第三次這樣在節(jié)日在我家鄉(xiāng)舉行．

解答 答案是B．本題考查固定句型：It+is/was+the 序數(shù)詞 time+that從句，從句需要用完成時(shí)．如果be動(dòng)詞是一般現(xiàn)在時(shí)is時(shí)，從句用現(xiàn)在完成時(shí)；如果如果be動(dòng)詞是一般過(guò)去時(shí)was時(shí)，從句用過(guò)去完成時(shí)；festival是被舉行，故答案是B．

點(diǎn)評(píng) 在掌握虛擬語(yǔ)氣的規(guī)則的基礎(chǔ)上，判斷題干屬于什么類(lèi)型的虛擬，然后根據(jù)語(yǔ)境，選用恰當(dāng)?shù)膭?dòng)詞形式表達(dá)虛擬．

7．Ladies and gentlemen，say hello to PIBOT．Developed in South Korea，this little machine is about the size of a child's toy，and has a head that kind of looks like a toaster （烤箱）．It's also able to fly a plane．
      The researchers responsible for the robot's development have actually managed to program it with all the knowledge and skills necessary to operate a standard airplane．Through a built-in webcam （網(wǎng)絡(luò)攝像機(jī)），PIBOT is able to gather information about its surroundings-such as location，airspeed，and weather conditions．
       With all of this information，it's able to make decisions in much the same way as a human pilot would．It's already completed one successful test flight-sort of．In the video presented at IROS 2014 in Chicago，PIBOT was seen guiding the airplane through a short test flight in a flight simulator （模擬器）-a process which included both takeoff and landing．
       It's super cool．
      Now，it's worth mentioning that-even as impressive as PIBOT is-we aren't going to be seeing it in any real airplanes at any point in the near future．Although the little robot is certainly able to operate a plane，it doesn't quite have the skills necessary to address some of the real world situations met by pilots-such as bad weather or mix-ups on the runway．It doesn't meet the government's rules，either．
      The inventors aren't terribly discouraged，however．They expect that it's only a matter of time before they manage to get PIBOT up to the necessary standards．When the day comes，we might see airlines put to work a whole new type of pilot； one who never tires，never gets hungry，and never makes mistakes．
      So…if you've a career in aviation （航空），it might soon be time to start planning for retirement （退休）．
28．We know from the text that PIBOTA．
A．is designed to operate a plane      
B．can serve as a toaster
C．was developed in Chicago            
D．is very large  
29．In the presented video，PIBOTD．
A．competed with a human pilot
B．completed several test flights
C．made decisions totally like humans
D．successfully guided a plane to take off and land
30．Why won't PIBOT be put into use？C
A．It can't predict weather conditions．
B．It doesn't have the skills to operate a plane．
C．It can't deal with real world situations．
D．It can't gather information abo ut its surroundings．
31．It can be learned from the text thatB．
A．PIBOT won't make any mistake in a flight
B．the inventors are confident about the future of PIBO．
C．the researchers will have to abandon the plan
D．PIBOT will surely replace human pilots one day．
