Read the following article and select the best answer. Article: Ceaseless technology. A punishing workweek. That to -do list that keeps multiplying. It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing ? One sleep expert, W. Christopher Winter raised the question. Sleeping binge Getting eight hours of shut-eye each night is generally recommended, but many people don't. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them " catch up" on lost sleep. They're likely right, " Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work," says Dr. Winter, a member of the American Academy of Sleep Medicine. Sleep banking Recent data suggests that banking sleep in advance of a long night can actually offset upcoming sleep deprivation . If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead. Routine naps A scheduled nap is healthier than catching up on or banking sleep. " Because sleep extension can make you feel groggy , I always recommend a short nap [if a person feels they need it ], at the same time, every day," says Dr. Winter. He adds that 25 minutes is ideal. " When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep," he says. That refreshing, scheduled break is better than an occasional weekend lie-in. " The body likes routine," he says, " When it's prepared, it works more efficiently." Question: Research shows that in the short term _ . - a nap have no effect on work - a nap have effect on work - recovery sleep does work - recovery sleep doesn't work
recovery sleep does work

Read the following article and select the best answer. Article: When I was in the third grade, I was picked to be the princess in the school play. For weeks my mother had helped me practice my lines. But once on stage, every word disappeared from my head. Then my teacher told me she had written a narrator's part for the play, and asked me to change roles. Though I didn't tell my mother what had happened that day, she sensed my unhappiness and asked if I wanted to take a walk in the yard. It was a lovely spring day. We could see dandelions popping through the grass in bunches, as if a painter had touched our landscape with bits of gold. I watched my mother carelessly bend down by one of the bunches. "I think I am going to dig up all these weeds," she said. "From now on, we'll have only roses in this garden." "But I like dandelions," I protested. "All flowers are beautiful-even dandelions!" My mother looked at me seriously. "Yes, every flower gives pleasure in its own way, doesn't it?" she asked thoughtfully. I nodded. "And that is true of people, too," she added. When I realized that she had guessed my pain, I started to cry and told her the fact. "But you will be a beautiful narrator," she said, reminding me of how much I loved to read stories aloud to her. Over the next few weeks, with her continuous encouragement, I learned to take pride in the role. The big day finally came. A few minutes before the play, my teacher came over to me. "Your mother asked me to give this to you," she said, handing me a dandelion. After the play, I took home the flower, laughing that I was perhaps the only person who would keep such a weed. Question: Why did the mother suggest a walk in the garden? - To remove the dandelions - To enjoy the garden scene - to help her daughter with the play. - to have a talk with her daughter.
to have a talk with her daughter.

Q: Read the following article and select the best answer. Article: While most of us are happy to take the credit when things go well, few of us are willing to take the blame when things go wrong. Rather than trying to hide our shame or embarrassment, experts found that we are simply less aware when our actions result in a negative outcome. The research may explain why we often feel it hard to take the blame for our actions. "Our result suggests that people may really experience less responsibility for negative than for positive outcomes," said Patrick Haggard, leading researcher and professor of the institute of Cognitive Neuroscience at University College London. In a series of tests, participants were asked to press a key. A sound then followed, either disapproving, neutral or approving, and they were then asked to estimate the time between the action and when they had heard the sound. Researchers found that individuals experienced different levels of responsibility depending on the outcomes. They also discovered they were significantly slower to recognize if their actions had resulted in a bad consequence, compared to when they had done well. "Effectively, we have found that we experience a negative outcome differently, not just retell it differently. We make a weaker connection when there is a bad result. And respond much more strongly when something good happens," said Professor Haggard. When something goes right, everyone wants to take the credit, and when things go wrong, nobody is interested in putting their hands up. The researchers said our brain is "very much concerned" with reward, as good results are key to survival. Although our own perception of whether we are guilty of something or not is changed by the outcomes, this does not provide a defense if we have done something wrong. "Our experience of our own responsibilities can be misleading and can be strongly colored by the outcomes of our actions," said Professor Haggard. "We have to take responsibility for what we actually do, not just for how we experience things." Question: Which of the following statements is TRUE? - Our level of responsibility can be strongly affected by the outcomes of our actions. - When something bad happens, nobody is interested in dealing with the problem. - People were quicker to recognize if their actions had resulted in a bad consequence. - Participants were asked to count the time between pressing a key and hearing the sound.
A: Our level of responsibility can be strongly affected by the outcomes of our actions.

As a result, students have to look for other less expensive options , such as renting books. Now, they find another way, that is, using textbooks on the Internet, uploaded by other students. It is hard to know how popular this practice will be, but many college students around the country are uploading their expensive college textbooks onto the Internet, so that other students can download them for free and avoid the big fees. A year ago, a student wrote a blog called Children of the Stars about a professor who insisted that students buy the newest edition of a specific sociology book for more than $200 and didn't allow them to purchase an older paperback edition of the same book for $5. The student wrote, "The newest edition of the book is so expensive. Fortunately, we found the electronic one online, which is very cheap. This is why we downloaded. " The blog is followed by a list of websites where people can download books. Curious about how varied the selection of books was and how easy it was to download them, Vocativ.com decided to do an experiment. The workers of it picked five typical and important courses of freshmen and tried downloading all these textbooks on the websites offered by the student who wrote Children of the Stars. They typed the titles of these textbooks into a computer, and found them immediately. Within minutes, they had four textbooks on their hard drive. It is illegal to upload or download copyrighted materials without permission, but students still do it due to its advantages. Besides, schools haven't taken action to stop it. Question: What did Vocativ.com find out from its experiment? - Downloading textbooks was easy. - Downloading textbooks was illegal. - Downloading textbooks was expensive. - Downloading textbooks was impossible.
(A).
