When you are stuck on a problem, sometimes it is best to stop thinking about it consciously. Research has shown that taking a break or a nap can help the brain create pathways to a solution. Now a new study expands on the effect of this so-called incubation by using sound cues to focus the sleeping mind on a targeted problem.
When humans sleep, parts of the brain replay certain memories, strengthening and transforming them. About a decade ago researchers developed a technique, called targeted memory reactivation(TMR), aimed at further reinforcing selected memories: when a sound becomes associated with a memory and is later played during sleep, that memory gets reactivated In a recently published study, scientists tested whether revisiting the memory of a puzzle during sleep might also improve problem-solving.
About 60 participants visited the laboratory before and after a night of sleep. In an evening session, they attempted spatial, verbal and conceptual puzzles, with a distinct music clip repeating in the background for each, until they had worked on six puzzles they could not solve. Overnight they wore special electronic uniforms to detect slow-wave sleep, which may be important for memory consolidation, and a device played the sounds assigned to three of the six unsolved puzzles. The next day, back at the lab, the participants attempted the six puzzles again. The subjects solved 32 percent of the sound-prompted puzzles versus 21 percent of the untargeted puzzles, a boost of more than 50 percent
''The researchers very bravely went for quite complex tasks that involved a lot of complex processing, and remarkably they found these really strong effects in all of their tasks, '' says Penny Lewis, a psychologist Cardiff University, who was not involved in the research. ''These are supercool results. Now we need to go out and try to understand them by firstly copying them and secondly trying to work out the component processes that are actually being influenced.''
Beyond providing new evidence that humans restructure memories while sleeping, the research may have practical implications. ''In a futuristic world, maybe TMR could help us use sleep to work on our problems'', says lead author Kristin Sanders, who was a graduate student at Northwestern University during the study Sleep-monitoring technology is increasingly accessible, and even without gadgets, future solvers can focus on important problems before bed.
Still, sleep is not magic. People need to do their homework and load their heads with the puzzle pieces involved. ''I'm not going to solve cancer with this technique, '' Sanders says, ''because I don't know anything about cancer research. ''
1.Which of the following has the closest meaning to the underlined word ''incubation'' in Para 1?
A.The pathway to a solution.
B.The period of taking a break.
C.Being stuck on a problem.
D.Targeted memory reactivation.

A.scientists wanted to prove that sound cues helped solve problems

Sometimes willpower is a lot like the television remote control--hard to find just when you want it most. Whether you’re trying to lose weight, stop smoking, get to the gym regularly, developing your sense of willpower is an important part of changing any behavior.1.But there are ways to increase your willpower.
Don’t try to change your economic situation, win a promotion and lose weight all on the same morning. Establish one clear, specific goal and make a realistic plan for achieving it. Extra willpower sometimes requires extra energy, so don’t stretch yourself too thin.2.Whatever your goal is, don’t expect to achieve it overnight.3.If you are trying to kick a caffeine habit, start by replacing your morning cup of coffee with a glass of water, instead of vowing never to drink coffee again. Congratulate yourself on the small achievements that will pave the way toward a larger one. These successes help your willpower grow.
4.Ask friends, family or colleagues for assistance and tell them exactly how they can help. If your credit card bills have increased sharply, for instance, let friends know that you are cutting back on expenses. Suggest having a common dinner instead of meeting at an expensive restaurant. Find a support group or organization related to your goal and attend their meetings. You can get valuable advice, understanding and information.
If possible, change your environment to encourage positive behavior. Want to get in shape? Keep an extra set of workout clothes in your office as a reminder to stop by the gym on the way home. Quitting smoking?5.
A. Change your environment to change your life
B. Real success takes time
C. Avoid bars or restaurants where you might be attracted to light up
D. Changing your behavior requires more than willpower

Are you sometimes stressed? Singing is a simple and effective way to reduce stress. It is beneficial mainly in the following three aspects.
Physical Benefits
1. This is especially recommended for the elders and those who have some form of disability in their voice. However, it is important to find a capable instructor to employ good singing techniques so as not to further damage vocal cords (声带) or lungs.
Singing also helps to improve your posture (姿势). Most people think that singing begins and ends with their mouth. 2. Singing practice will get you used to the proper body position of standing and help you form the good habit of standing straight.
Emotional Benefits
Singing helps in reducing your depression and lowering your stress level. When you sing, your body releases chemicals that make you feel happy, easing the tension and helping you to relax. 3.
Social Benefits
The social benefits of singing are huge. 4. So people who suffer from stage fright are advised to sing in front of family and friends before a live performance.
Singing is also very good for improving your communication skills. It is said that singing to babies helps to prepare their brains for language and may lessen the risk of language problems later in life. 5. The time spent in group singing, whether in a choir or at karaoke, creates a deep and lasting bond of friendship.
A. Try to regain your memory by singing.
B. First, it can help build up your confidence greatly.
C. When you sing, you can give your lungs a workout.
D Singing helps you to strengthen your immune system.
E. For adults, singing also enlarges your circle of friends.
F. In fact, the position of each body part affects your voice.
G. So, start to sing your favorite song next time you are feeling upset.
