  Many things can become distractions ( 分散注意力 ).  Your ability to focus your mind, emotions, and physical movements will directly influence your success. Staying focused on the task at hand can be easier said than done. Here are some powerful techniques that can help you improve your ability to focus.
For physical control, it helps to have a constant exercise schedule.  _Exercising helps you gain better command of your body, and even goes beyond the body, giving you more flexibility not just physically but also emotionally and mentally. When you feel more comfortable in your body, you increase your self-confidence, which helps you feel more relaxed.
For mental control, meditation (沉思;冥想) does the task.       It’s easy to get distracted by things in your background, but in order to perform well you have to maintain a high degree of focus. When you relax your thoughts, it trains your mind to deal effectively with outside distractions so you can stay centered on what matters most at the moment.
 It prevents you from overreaction and also from overacting. When your emotions settle down, you gain greater awareness of the environment you’re in, and feel calm and in control.
  The good thing is that self-control can be developed. Start exercising frequently, get yourself into meditation, and start to feel positive changes in your career and your life in general.

A．In short, focus requires self-control.

B．There are many benefits of exercising.

C．Generally speaking, you need to practise a lot.

D．There are still some disadvantages of exercises.

E. Your emotions are well served by meditation as well.
F. Focus is an important part of success and achievement in general.
G. It helps block out all the noise and activities that are going on around you.

根据短文内容，从下框A～F选项中选出能概括每段主题的最佳选项，并在答题卡上将该选项涂黑。选项中有一项为多余项。
A. How inner beliefs can help
B. Why are habits so important
C. How to develop positive habits
D. Improve your life
E. You can do it
F. Action plan
The single most important factor that contributes to success is what you do every single day. It is as simple as that. Your habits will determine whether you are successful or not. If you have strong and healthy positive habits, it does not matter whether or not you fail today because you are guaranteed to succeed in the long run.
________________________________
Because you repeat the same actions and the same behaviors every single day, a single positive action will not change your life, but the same action repeated 1,000 times will have a significant impact on your life. For example, if you go to the gym one time, you won’t see a big difference in your life. However, if you go to the gym 1,000 times over a five year period, you will see a big difference in your body. The same principle applies to finance, health, relationships, work, career, and school. Simple positive actions repeated every single day will have a great impact on your life in the long run.
_________________________________
There’s nothing easier than developing positive habits. You simply have to do every single day the action you want to make a habit. If you want to develop the habit of running, run almost every day. If you want to develop the habit of eating healthy, eat healthy every day. If you want to develop the habit of reading, read every day. Habits are created by repetition. The more you do an action, the easier it becomes in the long run.
__________________________________             
If you want to be successful in changing your habits, you should think about changing your inner beliefs about your habits. For example, your old belief was: “I love cigarette because it makes me feel good and relaxed. I need cigarette to be happy and relaxed.” If you keep this belief, you won’t be able to keep your resolution to stop smoking for very long. Instead, you should adopt this new belief: “I love yoga because it makes me feel good and relaxed. Cigarette is poisonous and destroys my body. Yoga makes me happy.” You should analyze your beliefs and make sure they won’t stop you from changing your habits. The same is true when you try to form positive habits. If you want to start eating healthy food, here are some positive beliefs you should start thinking about: “Healthy food is very good for my health. It gives me a lot of energy and I feel very good.”

It’s now time for you to develop positive habits in your life and avoid your negative habits. Write down 3 positive habits that you would like to develop and 3 negative habits that you would like to get rid of. For each positive habit, write down exactly what actions you’re going to take every single day in order to develop the new habit. For each negative habit, write down exactly what actions you’re not going to take in the next weeks. Here are some positive habits that will lead to success: exercise, healthy food, reading, saving, studying, healthy relationships, hard work, etc.. Here are some negative habits to get rid of: gambling, drug and alcohol abuse, overeating, shyness, etc..
____________________________________             
Everybody can change. All it takes is courage and commitment. Decide right now to improve your life by changing your habits. Take action right now! Don’t be afraid. Yes, you will probably make mistakes along the way. But never forget that success is guaranteed for you if you have positive habits in your life. If you refuse to quit, success will be yours.
