We often seek food after focused mental activity，like preparing for an exam.Researchers guess that too much thinking consumes a lot of energy from the brain.So the brain，sensing that it may soon require more calories to keep going，apparently leads to bodily hunger，and even though there has been little physical movement，we eat.
The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.
Because the brain uses sugar and lactate as fuel，researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.
Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was.Afterward，they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted.At a later date，the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.
Next，half the students sat quietly for 15 minutes，before being given pizza.The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking，repeated five times.These students were then allowed to gorge on pizza，too.But by and large，they did not overeat.
When the researchers factored in(将……作为因素考虑)the calories burnt on running，they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.
The researchers do not know if the runners consumed extra calories at dinner.They also cannot tell whether other types of exercise would have the same effect as running，although the researchers say they suspect that if an activity causes someone to break into a sweat，it should also increase blood sugar and lactate，feeding the brain and weakening hungers call.

We often focus on building relationships with others so that we forget the essential first step: being friends of ourselves. That is the crucial first step if we are to have good relationships with others. How can we have good relationships with others if we don't even have good relationship with ourselves? The problem might be worse than we expect. Maybe we don't like ourselves without realizing it.
For example, maybe you have made mistakes in the past which you feel bad about. You might be disappointed with yourself on why you could make such mistakes. Even if that happened in distant past, your subconscious (潜意识) mind still has a reason not to like yourself.
You might wish that you were born in different family, or that you have different background. Maybe you could not accept the fact that you are not as lucky as others, who seem to get whatever they want effortlessly because of their background.
You might have some personal traits that you don't like. For example, you may be an introvert ( 内向的人) and you don't like it; you wish you are an extrovert (外向的人).
Your achievements relate to others. They might have better achievements than you, and no matter how hard you tried, it might seem impossible for you to match them. You might then think that it's because you are not smart enough or don't have enough talents.
Is there anything that resonates (产生共鸣) with you? All these give reasons to you not to like yourself. That in turn makes it difficult for you to be a good friend to yourself.
Fortunately, there are always things you can do to fix the situation. Here are some tips:
1. Forgive yourself.
2. Accept things you can't change.
3. Focus on your strengths.
4. Write your success stories.
5. Stop comparing yourself with others.
6. Always be true to yourself.
59. The underlined word "traits" in the fourth paragraph probably means
A. particular qualities B. some disadvantages
C. special abilities D. training courses
60. One can't be friends with himself because
A. he won't forgive others' mistakes
B. he dislikes his background
C. he accepts some of his personal traits
D. he is proud of himself
61. Which of the following is TRUE according to the passage?
A. Resonating is very important for making friends.
B. How to make friends with ourselves is very difficult.
C. Writing your success contributes to stopping comparing with others.
D. Realizing your own advantages and good is good to you.
62. Which of the following is NOT mentioned according to the passage?
A. It's normal to make mistakes, so do yourself a favor by giving yourself forgiveness.
B. You will feel much relaxed if you treat things you can't change the way they are.
C. It's useless to compare yourself with others.
D. If you have a good family, you'll make friends with yourself.
