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.

【小题5】

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.

How to Speak in Public

Many people have a fear of public speaking. They worry that they will lose their words，bore the audience or somehow make a fool of themselves. It is easy to try to avoid public speaking，but that usually doesn't work out. Everyone has to speak publicly at some point in their life. You may give a speech in a class or a meeting. Maybe you'll have to give a speech for some honor you've received. 【小题1】

Relax. 【小题2】 Your audience don't expect you to be perfect. They want you to succeed just as much as you do. If you're thinking you'll forget everything，remind yourself that you are prepared and knowledgeable. Imagine yourself doing well.

Be yourself. You are not Jack Canfield or Tony Robbins. Share your true personality with your audience，and they'll find you reliable. 【小题3】

Know your topic. Try to speak about the subject you know well. Research the topic to make sure that you are correct. Public speaking is easier when you don't feel like a fraud（骗子）.

【小题4】 Choose your message for the group you are speaking to carefully. If you' re giving a public speech, then rude jokes certainly won't be suitable.

Give value. Base your speech on 2 or 3 main points. 【小题5】 They' ll be satisfied if they leave with something they can use, and that is what public speaking is all about.

   Every day you have so much to read-official documents, friends' emails, textbooks, newspapers, and your favorite articles and an endless list. 【小题1】 Certainly yes.

【小题2】If you are attempting an exam where you have to comprehend the given paragraphs and answer questions in a limited time then you should know techniques of reading faster. 【小题3】 Yet, another technique for faster reading is skimming-you can use this for reading long emails or articles to get the main idea but obviously, you cannot use this while comprehending the given paragraphs in an exam. However, if you are reading for personal growth then it is not the number of books you have read but how much you have extracted（摘录）out of your readings【小题4】.

【小题5】If you are reading a textbook then keep a notepad and a pen ready to keep jotting（匆匆记下）all the main points. If you think that you will make notes on second reading then remember: there is no time for a second reading.

How was everything going？I，together with my parents plans to take a trip to Canada for a week during the summer vacation. We hope to make the full use of this opportunity to experience the naturally beauty of Canada and learn more about its culture. We don’t want to go to places where are full of tourists and shoppers. Because I am writing to ask help. We hope you can tell them where to visit. Besides, can you give us some advices on how to finding hotels which are not expensive but comfortable? I would be grateful if you could give me an early reply.

Yours,

Reducing Test Anxiety

Test anxiety arises when a student excessively worries about doing badly in a test. This can become a major hindrance (造成妨碍的事物) to test performance and cause extreme nervousness and memory problems among other symptoms. 【小题1】

Think positively. Scientific research has shown that our expectations can affect our performance. 【小题2】However, if you expect that you’ll do poorly, studying may not be enough to help you perform well. Therefore, it is a wise choice to think positively.

【小题3】 Fear releases adrenaline (肾上腺素) , preparing the body to deal with danger. Your heart rate and breathing speed up and you may feel shaky, sweaty, or dizzy. Anything you can do to reduce these physical reactions will help you think more clearly and feel more confident.

Eat before the test. Don’t skip breakfast to study. 【小题4】 Choose protein-filled snacks and avoid sugar, which can give you quick energy that may run out in the middle of the test. Eat something even if you feel sick—try crackers or toast to settle your stomach. Avoid caffeine and energy drinks, which can increase anxiety.

Get a good night’s sleep before the test. Studies have shown that you will do well in the test if you get enough sleep. 【小题5】 If the test is later in the day or the evening, or if you just couldn’t get a full night’s sleep, take a nap. Research has shown that a short nap—less than an hour—can improve alertness, memory, creativity,  productivity, and moods, and can decrease stress.
