Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”
In medical school, most doctors learn that people with chronic conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．
If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．

Fear can be a wonderful feeling in our lives, protecting us from dangerous situations and keeping us safe. But fear can also limit our lives significantly. While it may not be conscious, fear may make us think we are unacceptable or that what we have to offer isn’t valuable. Fear may make us feel that we are not safe being ourselves.
To avoid feeling fear, we may limit our lives greatly, living in tiny boxes. Living this way gives us the illusion(假象) of safety but leaves us with an unfulfilling life of no passion. If we shine a light on many of our fears, we see they have a very limited view of what is “safe” and how to “protect” us. Many of our fears are concerned only with protecting us from humiliation(羞辱) and failure. While these fears are doing their jobs incredibly well, they are doing so with faulty and outdated programming. Many fears we have as adults are trying to protect us as they protected us when we were children. Indeed, many of our current, automatic reactions to fear were actually formed when we were children.
Even so, it’s important not to judge ourselves for feeling these types of fears. If we judge ourselves, we will bury our fears or disguise them. By denying our fears, however, we also deny our energy, creativity and passion.
So what do we do with fear? We recognize the fear for what it is--- a feeling we’ve experienced many times in the past and a feeling we will experience many times in the future. We become very familiar with our own particular brand of fears and how we allow them to control our lives. It is especially beneficial for each of us to become aware of the particular behavior patterns we’ve adopted when we feel fear, so we can look at our reactions with a sense of humor and compassion. Then, if we wish, we can choose a different response, which can be a scary yet very exciting experience.
66. According to the first paragraph, fear sometimes .
A. protect us when we’ve made mistakes B. makes sure our feelings are not hurt
C. brings great change to our everyday life D. makes us lose confidence in ourselves
67. It can be inferred from the passage that the author .
A. thinks it difficult to control our fear B. believes fears protect us negatively
C. thinks it’s good to criticize ourselves D. values the advantages of feeling fear
68. According to the author, the ways we react to fear .
A. vary from person to person B. have been formed since childhood
C. develop during our growth D. will not change until we get old
69.The last paragraph mainly tells us .
A. what is the essence of fears B. usual reactions we have when feeling fear
C. how to deal with fears reasonably D. the importance of humor and compassion
70.What would be the best title for the passage?
A. Is fear managing your life? B. Be calm when feeling fear
C. What do you fear most? D. Passion, chance and fear
