     Baking soda
     Paper

完形填空。     Our thoughts, words, and actions often cause harm to others and to us. Without reconciliation (和解), we
cannot deepen our understanding and only cause more suffering."Beginning Anew" is a(n)   1 of reconciliation.
It involves three steps-sharing appreciation, expressing   2 , and expressing hurt and difficulties.
     In the first step, we share appreciation. We acknowledge the   3 qualities of the other person. The second
step-expressing regret, is to   4   with the other person our regrets for the things we have done or said that
might have caused him or her   5 . This requires humility (谦逊), and the   6   to let go of our own pride. In
the third step, we   7 our own hurt with mindful and loving   8 without blaming or criticizing. We speak in
such a way that the other person can listen and   9 our words. If we  10  the other person, his heart will   11

acted as he has, causing us so much pain. Perhaps, later, he can share his feelings   13 we can understand
him more deeply. If a strong  14  arises in us while we are expressing our suffering, we should simply   15
and come back to our breathing until the emotion becomes  16 . The other person can  17  us by following his
breathing until we are ready to continue. We can enjoy practicing"Beginning Anew" with our partner, our family,

     Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch.
They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat.
However, the real reason lies inside their bodies. At that time-about eight hours after you wake up-your body
temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits
in experiments where there was no night or day. The people in these experiments almost always followed a
similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
     In many parts of the world, people take naps (小睡) in the middle of the day. This is especially true in
warmer climates (气候), where the heat makes work difficult in the early afternoon. Researchers are now
saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind
and therefore is good for health in general. In countries where naps are traditional (传统的), people often
suffer less from problem such as heart disease.
     Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps,
employers do not allow it! If you do have the chance, however, here are a few tips about making the most
of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep
too late in the day may only make you feel more tired and sleepy afterward. This can slao happen if you sleep
for too long. If you do not have enough time, try a short nap-even ten minutes of sleep can be helpful.

1. If you get up at 6:30 am, what is the best time for you to take a nap?

A. About 12:30 pm
B. About 2:30 pm
C. About 1:30 pm
D. About 3:30 pm

2. What advice does the writer give on taking a nap?

A. You"d better take a nap about an hour after you have lunch.
B. You can sleep as long as you like so that you will not feel tied or sleepy.
C. Only people in warmer climate need to take a nap.
D. If your time is limited, a short nap can also help.

3. Naps are good for everyone in any climate because _________ .

A. a nap makes both your body and mind have a good rest.
B. a daily nap benefits your health.
C. people who often take naps suffer less from problems such as heart disease than those who don"t.
D. All the above.

4. What would be the best title for the text?

A. Just for a Rest
B. All for a Nap
C. A Special Sleep Pattern.
D. Taking Naps in Warmer Climate.

Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date? Many people are afraid of assert themselves, that is to say dare not state their opinions confidently. Dr. Albert, author of Stand up, Speak Out, and Talk Back, thinks it is because their self-respect is low."Our whole set up (体制) is designed to make people distrust themselves," says Albert. "There is always "superior" around - a parent, a teacher, a boss-who"knows better". These superiors often gain when they chip (削弱) away at your self-image." But Alert and other scientists are doing something to help people assert themselves. They offer "assertiveness training" courses-AT for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more active without hurting other people. In one way, learning to speak out is to overcome fear. A group taking an AT course will help the timid person to lose his fear. But AT uses an even stronger motive the need to share. The timid person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-image. If someone you face is more "important" than yon, you may feel less of a person. You start to doubt your own good sense. You go by the other person"s demand. But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.
1. What is the best title for this passage?
A. Assertiveness Training B. The importance of self-image C. Development of Self-respect D. How to Feel Good of Yourself
2. The underlined word "timid" in this passage probably means"_______"?
A. brave B. active C. angry D. shy
3. Which of the following problems is mainly discussed in this passage?
A. People are easily cheated when they buy something B. Some people usually think too low of themselves C. People are usually afraid of their superiors D. Some people are not used to making their ideas public
4. We may infer from the passage that the writer"s attitude towards the whole set up is _______.
A. positive B. negative C. appreciative D. aggressive

Exercise is one of the few factors with a positive role in long-term maintenance (保持) of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical exertion (体能). The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to remove pounds said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure (卡路里的消耗) charts; for example, one would have to actively walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals admit half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President" s Council on Physical Fitness and Sports. Still, exercisers supporting role in weight reduction is important. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed (证实) that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine (常规)maintained their new weight. If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year"s time, supposing no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
1. What is said about the average American in the passage?
A. They usually ignore the effect of exercise on losing weight. B. They prefer"light" beer and low calorie bread to other drinks and food. C. They know the factors that play a positive role in keeping down body weight. D. They tend to overemphasize the healthful effect of"light" beer.
2. Some people dislike exercise because ________.
A. they find it hard to exercise while on a diet B. they don"t think it possible to walk 3 miles every day C. they think it is physically exhausting D. they find consulting caloric-expenditure charts troublesome
3. What was confirmed by the Boston University Medical Center"s study?
A. Weight reduction is impossible without exercise. B. Even occasional exercise can help reduce weight. C. Controlling one"s calorie intake is more important than doing exercise. D. One could lose ten pounds in a year"s time if there"s no increase in food intake.
4. What is the author"s purpose in writing this article?
A. To stress the importance of maintaining proper weight. B. To support the statement made by York Onex. C. To show the most effective way to lose weight. D. To introduce the study of the Boston University Medical Center.
