Brain fitness has basic principles：variety and curiosity. When anything you do becomes second nature，you need to make a change.If you can do the crosswords（纵横字谜）in your sleep，it’s time for you to move on to a new challenge in order to get the best workout for your brain. Curiosity about the world around you，how it works and how you can understand it will keep your brain working fast and efficiently.【小题1】

Play Games

Brain fitness programs and games are a wonderful way to tease and challenge your brain. Sudoku，crosswords and electronic games can all improve your brain’s speed and memory. These games rely on logic，word skills，math and more.【小题2】 You’ll get more benefit by doing these games a little bit every day—spend 15 minutes or so，not hours.

Think Deeply

Thinking deeply every day is perhaps the single greatest thing you can do for your mind or body health.【小题3】

Eat for Your Brain

【小题4】 Focus on fish oils from wild salmon（鲑），nuts such as walnuts，seeds such as flaxseed and olive oil. Eat more of these foods and less fats. Remove trans fats（反式脂肪）completely from your diet.

Stories are a way that we strengthen memories，explain events and share moments. Practice telling your stories，both new and old，so that they are interesting，attractive and fun. Some basic storytelling techniques will go a long way in keeping people’s interest both in you and in what you have to say.

   Everyone can benefit from good communication（交流）.【小题1】. Of course，we know that isn’t true，but this shouldn’t stop you improving your communication skills. Here are a few tips to help you become a better communicator.

【小题2】

Verbal（口头的）language is only one part of the communication—body language is another. If you once wanted to know how to tell if someone is lying，body language is the answer. Your body language tells other people what you aren’t verbally saying，such as if you are anxious，confident，confused，angry or in any other type of emotion or state of mind. If you become great at reading body language，it will help you become a better communicator.

Listen to others

Before you begin to speak，take a minute to see if anyone else has something to say.【小题3】 .Listening to others has many benefits，such as allowing you to learn new things or get the information that you may later need.

Think before you speak

Your parents probably have told you this since you were a child，but many people still do not take a moment to think about the words they are about to say.【小题4】. There is a time and place for all words and tones of voice.

【小题5】. You will have to practice your communication skills before you can become an excellent communicator.

   Now a new study has showed a key trick in getting the best deal - asking for a range of pay, rather than a single figure.

The research contradicts（与……抵触）traditional wisdom that argues giving a range will automatically cause employers to focus on the lower end of the offer. For instance, if you want  $90,000 and you suggest a range between $90,000 and $110,000, the study finds employers are more likely to make a higher offer.

But simply asking for $110,000 in the first place increases the chances of the deal falling apart, as it is a sign that the employee is not open to negotiation（协商）.

The team made the discovery after running a series of experiments involving Amazon Mechanical Turk workers and business school students.

Respondents were asked not only what they thought their negotiation partner's lowest acceptable offer could be, but also questions designed to show how they viewed their partner.

One type of offer, called a “bracketing” range,places the figures on either side of the desired salary. For instance, if you want $90,000, you'd ask for a range of between  $80,000 and $100,000. This causes employers to offer the lower end of the scale,but, unlike single figure offers, the deals rarely fall apart as the negotiator is often viewed favourably. “If your goal is to get along with someone without losing money, the‘bracketing' range offers may be a good move,”Dr Ames told the Wall Street Journal.

The“backdown”range offer, meanwhile, uses the target salary as the high figure in the range. For $90 ,000, an employer would ask for a range between $70,000 to $90,000. These range offers , predicta-bly, give the worst results in terms of pay.

However, Dr Ames warns against setting the range too high and says the most successful range is usually within 20 per cent of the target offer.
