Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now... perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers? While many flights by plane are controlled automatically by machines, most people today wouldn't let their car drive itself. That's because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won't turn the car right or left. It won't stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS(global positioning systems) that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at. In addition to computers being 'smarter' than people regarding the best way to go or knowing how close another vehicle is, computers don't get sick, tired, or angry. This means they won't make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend's personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle. So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn't... Which of the following is the disadvantage of an autopilot system? A) It won't make the same mistakes as people do. B) It can point out the best route for the driver. C) It might not respond properly to unexpected situations. D) It does not have human emotions to influence its function.

Go, known as Weiqi in China and Baduk in South Korea, was viewed as the last game where humans can defeat machines. Lee Se-dol, one of the greatest Go players, has won 18 world championships for 21 years of his professional career. AlphaGo, a computer program developed by Google's DeepMind, beat the European Go champion, an achievement that was not expected for years in October, 2015. The match between Lee and AlphaGo was seen as a representative game between humans and Artificial Intelligence (AI). The match of the century drew great attention from news organizations, Go fans and the general public across the world as well as in South Korea. Go originated from China more than 2,500 years ago. It involves two players who take turns putting markers on a net-shaped board to gain more areas on it. One can occupy the markers of the rival by surrounding the pieces of the other. Go is considered to be a lot more complex than chess where artificial intelligence scored its most famous victory to date when IBM's Deep Blue beat grandmaster Gary Kasparov in 1997. But experts say Go presents an entirely different challenge because of the game's incomputable number of move options. In other words, the computer must be capable of human-like "intuition" to win. "I was very surprised because I did not think that I would lose the game," said Mr. Lee.He said AlphaGo's early strategy was "excellent" and that he was shocked by one unconventional move it had made that a human never would have played, which he believed directly resulted in his loss. AlphaGo is proud of a deep learning capability to learn for itself and discover new strategies by playing games against itself and adjusting neural networks based on a trial-and-error process known as reinforcement learning. In spite of his loss, he did not regret accepting the challenge. "I had a lot of fun playing Go and I'm looking forward to the future games," he said after AlphaGo won 3-0 in a five-game match. "Playing against a machine is very different from an actual... What did Lee think was the cause of his loss? A) AlphaGo had an excellent strategy and unconventional moves. B) He couldn't sense AlphaGo's breathing and energy in the games. C) He made decisions depending on the rival's physical reactions. D) The designer of AlphaGo was a talent who couldn't be defeated.

Christmas Eve was tomorrow. I hoped one of the packages that held a camera had already been placed under the Christmas tree. It was the only thing I wanted. I had been _ to my parents. I love taking photos. My bedroom walls are covered with photos I had taken with my mom's old camera. I'm always trying to capture those perfect moments in which you can hear the laughter or touch the beautiful scene, but my camera has always seemed to fall short. I knew Mom had put a few presents under the tree this morning, so I went on a hunt in my mom's room. I opened the door and found my Christmas present was lying unwrapped on the floor -- a big pink cat. I felt so disappointed. Mom seemed to notice that, and she tried to cheer me up. "Stacy, I got your present today. I am so excited to surprise you!" "I can't wait," I said. The next day I couldn't wait any longer. I needed to tell her. "Mom, may I talk to you for a second?" "Sure, dear. What do you need to talk about?" she asked. And so it came -- how upset I was that I was getting a cat. "Stacy, that cat is for your sister Julia!" she said with a smile. "Then what am I getting?" I asked. She just smiled. "You'll have to wait and see." Next morning, I happily got into the living room and sat next to the tree. I pulled out the box with my name on it and opened the wrapping paper to find ... My camera! "Thank you!" I said to both Dad and Mom. Dad picked up the camera and took a picture of Julia, Mom and me. It has become one of my favorite pictures. Just on that Christmas morning, I took lots of photos with my camera -- my little sister making a face, my parents giving me a soft smile -- and all of these photos have come to mean one thing to me: love. We can learn from the passage that _ . A) her mother bought Stacy a camera after discovering her disappointment B) her mother knew what gift Stacy wanted for Christmas C) Stacy thought it's OK to have an old camera D) Stacy finally got her gift on Christmas Eve
