     Who hasn't found themselves reaching for the closest food available when they're tired and stressed?
More and more research is proving that this isn't all in our mind. Some foods really do lead to a change
in our moods (心情).
     Carbohydrate (碳水化合物) that calm
     This is how some people medicate themselves with food-by reaching for cookies or pasta (面食)
whenever they're upset. Unfortunately, it doesn't always work. You must eat a meal consisting of 100%
carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good
mood.
     To get the wished-for effect, you must not eat anything for four hours and then eat at least 30 grams
of straight carbohydrate. Dry cereal (麥片), a piece of bread with jam, or a potato should do the trick.
     Protein (蛋白質) for Power
     Of course, sometimes we don't need to be calm and sleepy. Sometimes we need a great deal of mental
concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the
tryptophan (色氨酸) from flooding your brain, and the rise in serotonin won't occur.
     Why dessert makes up Happy
     Fat and sugar cause the brain to let go endorphins (內啡肽), which send pleasure signals throughout
the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.
     You can also satisfy your sweet tooth by choosing fruit for dessert.
     Timing your meals for energy
     Blood sugar drops after four hours of going without food, causing a decrease in energy. Eating usually
fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy.
     When you eat has as much of an effect on your mood as what you eat. If you regularly go for a long
period of time between meals, rethink your schedule and plan ahead.
1. The underlined phrase in the third paragraph means _____.
A. be extremely smart
B. intend to cheat someone
C. bring about the desired result
D. do something to amuse people
2. The function of protein is _____.
A. to help you keep calm and sleepy
B. to make you feel energetic
C. to lead you to slowness
D. to increase serotonin in your brain
3. We can infer from the last two parts that _____.
A. fat and sugar can greatly help people feel happy
B. we humans tend to eat lots of cookies and cakes
C. the more we eat, the faster we will gain energy
D. what we eat is more important than when we eat
4. The main idea of the passage is _____.
A. eating for a better mood
B. eating to make you calm
C. eating for more protein
D. eating to make us strong

     One year ago today, seven patients shared their stories of illness and recovery on the New York Time Well
(a blog), according to a report published in April,2009.
     They were the first Patient Voices, a regular series that offers a first person (第一人稱的) description of
the challenges patients face as they deal with different kinds of health problems. Since the first Patient Voices
appeared, New York Times producer Karen Barrow has continued to give a voice to a lot of patient stories.
     We heard from Jacqueline Castine of Bloomfield Hills, Mich,who had bipolar disorder (躁郁癥), and whose
son also suffered from mental (精神的) illness."I could not save him," she said."I could not fix (懲罰 ) him.
He leaves a beautiful daughter and a very sad mother."
     And there is runner Alyssa Johnson,43,who was training for the Boston Marathon in 2003 when she began
showing the first signs of Parkinson's disease." Sometimes when I'm running I'll come to a long downhill, and
my legs work the way they used to work and my arm swings (擺動) the way it used to. It's like running before Parkinson's, and that's the best feeling.
     And then there's the voice of Robin Grinsted, 50, of Swansea, S. C.,who has H. I. V. She is refused by her
church and feels lonely."They're not accepting," she said." But I know there will be people putting their arms
around me some day."
