Read the article and select the best answer. Article: I am a senior in high school. For four years I have been a member of the marching band at my school---four years of commitment to an organization of 150 kids, four teachers and 100 parents working from August to June of every school year. For four years, my mom has been there for me---never complaining and never receiving a "Thanks, mom." My mom is pretty much a supermom and, unfortunately, it took me some seventeen years to realize it. "Driver" is probably a more appropriate name for her. Every concert, every competition, every football game, my mom was there with a smile, and always stayed to watch. When she couldn't be there, she would be waiting for me when the bus pulled in to the school's parking lot. She actually enjoyed arriving at the school at 10:30 at night just for me to tell her that I was going out with my friends and that I needed twenty dollars instead of a ride home. Now that I'm a senior, I have my own car and drive myself to my football games and concerts. My mother still comes to watch me. Recently, my band was invited to play for a celebration. When the bus pulled up to the flagpole in front of my high school, I had the strangest feeling. Something was missing. I found myself nervously searching for my mom in the parking lot. I needed to tell her I didn't need a ride home; I was going out. I then realized my mother was at home and probably in bed. I never realized how much I took her for granted until she wasn't there. When I got home that night, I woke her up and told her I loved her and I missed her. I told my mom that I really appreciated all the times she had driven me back and forth. I told her I was glad she embarrassed me all those times, because I knew that it just meant she loved me, too. My mom looked back at me with tears and a big smile.

Read the article and select the best answer. Article: Naps--short sleeps during the day--may improve memory, experts said recently. New research conducted by brain researcher Avi Karni of the University of Haifa in Israel explores the possibility that naps help lock in sometimes long-term memories. "We still don't know exactly how memory system works during sleep, but the results of this research suggest it is possible to speed up memory consolidation ," Karni said. Long-term memory refers to memories that stay with us for years, such as "what" memories -- a car accident that happened yesterday-- or "how to" memories, such as one's learned ability to play the pianos. Karni, also one of the authors of the study published in a recent issue of the journal Nature Neuroscience, instructed participants to learn a difficult set of finger games, then divided the study _ into two groups: one that napped for an hour, and one that didn't. The people who took an afternoon snooze showed obvious improvement in their performance by that evening. "After a night's sleep the two groups were at the same level, but the group that slept in the afternoon improved much faster than the group that stayed awake," Karni said. And the study also showed just how much faster a 90-minute nap could help lock in long-term memories. "Daytime sleep can shorten the time 'how to' memory weakens and forgetting starts,"Karni said, "Instead of 6 to 8 hours, the brain consolidated the memory during the 90-minute nap."

Ques: Read the article and select the best answer. Article: Do lobsters, crabs and other crustaceans feel pain? We certainly act as if they don't.Most chefs cook lobsters and crabs alive, usually by dumping them in boiling water.Along with melted butter.That's the appeal of crustaceans-there's no fresher food.We may feel a bit of guilt, or maybe just discomfort, when we hear the creatures rattling around the inside of the pot as the water boils.But that feeling usually _ for lobster lovers by the time we crack open a claw and dig out the delicious meat.We wouldn't dream of doing the same thing to a live chicken or pig which are dead well before die cooking process begins, but those crustaceans are different.They don't even feel pain.Right? Actually, they just might.That's the conclusion of a new study published in the Journal of Experimental Biology.Robert Elwood and Barry Magee of Queen's University in Belfast examined the reaction of common shore crabs to small electrical shocks. Ninety crabs were placed in a brightly lit area and were given the choice of moving to one of two dark shelters.(Shore crabs like to hide in dark, tight spaces.) Once they'd made their choice, the crabs in one of the shelters were exposed to an electric shock.After a rest period, the crabs were returned to the lit tank.Most of the crabs went back into the dark shelters, and then the same crabs were given another electric shock.When they were placed back into the lit tank for the third time, the majority of the shocked crabs instead went to the other dark shelter, avoiding the one where they had repeatedly been shocked. As Elwood put it, the crabs' choice indicated they wanted to escape the shocks: Having experienced two rounds of shocks, the crabs learned to avoid the shelter where they received the shock. They were willing to give up their hideaway in order to avoid the source of their probable pain. Question: What does Robert Elwood and Barry Magee's new study prove? Options: A: It is hard to tell whether a voiceless shore crab is feeling pain or not. B: Shore crabs react to electric shocks and seemingly feel pain. C: Shore crabs prefer a dark, tight shelter as their-habitat. D: Bright light causes discomfort to crustaceans.

Question: Read the article and select the best answer. Article: Sooner or later, many families will face the situation of moving. The experience can be very bad for kids, who may not be a part of the decision to move and may not understand it. You can take steps to make the entire process easier for everyone. Many kids like to stay in familiar places. So as you consider a move, weigh the benefits of that change against the comfort that neighborhood, school, and social life give your kids. If your family has recently dealt with a big life change, such as death, you may want to put off a move to give your children time to accept the fact. The decision to move may be out of your hands, perhaps because of a new job or money problems. Even if you're not happy about the move, try to keep a positive attitude to it. During the move, a parent's attitude can greatly influence kids. No matter what the results are, the most important way to prepare kids to move is to talk about it. Try to give your children as much information about the move as possible. You can ask kids to join in the planning such as house-hunting or the search for a new school. This can make the change feel less like it's being forced on them. If you're moving across town, try to take your children to visit the new house and the new neighborhood. A move can have many problems, but good things also come from this kind of change. Your family might grow closer and you may learn more about each other by going through it together. Question: The author wrote this text mainly to tell us _ .
