[Q]: Article: An annoying problem for humans, who like to boast   about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there? The deepest oil well enters a mere six miles into the crust   (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle  . Sadly the project involved government supporting. It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust ---  about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible. What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes. So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack  . Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten   iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface. Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises." This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.

[Q]: Article: Rebecca, who is a 25-year-old woman, has a rare condition. She can remember all the events she has experienced in her life. The events are so vivid, as if they happened just moments ago. But her vivid memories often become a reality. Rebecca said, "When I relive memories, the emotions come back. So if it's something that happened when I was younger, my emotions are about what I felt then. I also re-experience pain. For example, I remember falling over and hurting my left knee when I was three. When talking about it now, I'm getting pain in my left knee." However, there are times when Rebecca's memories prove to be too overwhelming, and she has learnt relaxation and mindfulness  techniques to solve. "At school, it is a _ . I'm not very quick at processing things, so there is always so much going through my mind. At night, I have to sleep with the radio on and a soft light. If it's too dark or quiet, my mind just recalls all these memories and I can't sleep," Rebecca said. In addition, Rebecca has no control over whether the memories she recalls will be positive or negative - recalling painful experiences with such vividness that she has suffered from post-traumatic   stress disorder. Rebecca said, "Recently, I went back to my old school for my sister's high school graduation. Being in that building again brought all those memories flooding back. I burst into tears and had to leave." Rebecca and her mother Mrs. Barnes got in touch with the University of California in 2011. It was there that Rebecca knew she had Highly Superior Autobiographical Memory (HSAM). It's reported that Rebecca is one of just 80 people worldwide, who have HASM. "Finding out about HASM has been such a positive experience. Now, Rebecca has been more positive and able to do things independently, which has been excellent," Mrs. Barnes said. 
 Question: What's wrong with Rebecca? 
 Options: (A) She hardly sleeps well at night. (B) She usually gets hurt easily by others. (C) She can't distinguish between reality and dreams. (D) Her vivid memories lead her to experience sufferings. 
 Asnwer: C
[A]: No


[Q]: Article: Most people who experience bad service while traveling, shopping, or dining out do no complain. They accept bad services or products without making a sound. Why? Many feel complaining won't do any good. In fact, they're wrong, because companies don't want their customers unhappy. Not sure you can do it? Here are some ways to use when things go wrong. 1.If you have a complaint, do something about it right away. The longer you wait, the harder it will be to get your complaint solved. 2.First, complain to the servers. If they are not going to solve your problem, then ask politely to speak to a manager. And if that doesn't work, you can always request to speak to the manager's manager! 3.Demand a discount . Let's say you were promised a hotel room with an ocean view, but got a view of a brick wall instead; if you were promised a seat in the front of a plane, but got a seat in the back. You should do something about both of these situations. Ask a special discount. 4.Don't be passive. Offer ways you think the company can satisfy you. 5.Insist on the price you were told. If you are refused, get a manager's name and telephone number, and promise to follow up with a letter and a telephone call. 6.If all else fails, wait until you get home and take action. Call the company's head office, and speak to the most powerful person possible. Then follow up your call with a letter of complaint. If necessary, call the customer protection office in your city and complain.
