Why are people interested in eating raw foods or whole foods (天然健康食品) ? One reason is that eating these types of food reduces the risk of acid (酸) accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is overweight. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive system, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods (加工食品) contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陳代謝) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive system makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach. One effective way is to choose raw and whole foods appropriately according to your health conditions and personal preferences.
小題1:It can be inferred from Para. 2 that __________.
A．we’d better be cautious about raw and whole foods
B．foods with natural enzymes help people keep fit
C．it is important for people to protect their vital organs
D．giving up cooked and refined foods is a new lifestyle

小題3:What is the main purpose of this passage?
A．To warn people of the problem of overweight.
B．To inform people of the harm of processed foods.
C．To advocate eating more raw and whole foods.
D．To tell the differences between raw and processed foods.

As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you.
小題1:We know from the second paragraph that ______.
A．the common cold is caused by only one virus
B．there are people who never catch a cold
C．colds can be caused by different viruses
D．a(chǎn)ll people are easily attacked by colds
小題2: The underlined word “transmitted” in the fourth paragraph means “______”.
A．passedB．changedC．curedD．caused
小題3:If you have a cold, you can do the following except ______.
A．drinking a lot of waterB．drinking chicken soups
C．eating honeyD．forcing yourself to eat
小題4: It can be inferred from the passage that ______.
A．now scientists have found out practical treatment for colds
B．different people may have different ways to fight against colds
C．working in freezing weather is the main reason for colds
D．colds can be passed from animals to human beings

A friend of mine was in low spirits one day. He usually dealt with this state of mind by avoiding people until the mood passed. But on that day Fred had an important meeting with his boss, so he decided to put on a false front. During the meeting Fred smiled, joked and played the part of a happy, good-natured person. To his surprise, he soon discovered he was no longer depressed. 
Without realizing it, Fred chanced to find an important new principle of psychological research: acting a part can help us feel the way we want to feel — more self-assured in a trying situation, more cheerful when things go wrong.
How can you put this principle to work in your own life? There’s more involved than simply mimicking a few expressions. You have to be systematic about it. Here’s how:
Smile to cheer yourself up.
Relax to reduce anxiety or fear.
Look your best to increase your self-confidence.
Keep cool in a crisis.
Using our bodies and actions to change the way we feel can be a useful tool in helping us through life’s difficult times. As novelist George Eliot wrote more than a century ago, “Our deeds determine us, as much as we determine our deeds.” People who remember that — and act upon it — can only be richer and happier for the experience.
小題1:In paragraph 1 the underlined phrase “to put on a false front” means ______.
A．to wear a wrong coat
B．to act a part unsuccessfully
C．to show a pretended happy appearance
D．to put on airs
小題2:According to Paragraph 1, Fred ______before the meeting.
A．had very few spirits
B．had many spirits
C．was in bad mood
D．was in good mood
小題3:The underlined phrase “mimicking” in Paragraph 3 most probably means ______.
A．learning quickly
B．making faces
C．behaving well
D．imitating others
小題4:In the last paragraph, the quotation “Our deeds determine us, as much as we determine our deeds” may show that ______.
A．a(chǎn)ctions speak louder than words
B．the more we do, the happier we are
C．our feeling cannot change our behavior
D．a(chǎn)ctions are very important for us to beat bad moods for good

I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the morning if you want to.
I know lots of women who don’t have breakfast, and they have many different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories（卡路里）, still others just don’t like breakfast food.
But eating in the morning is very important when you’re trying to lose weight. Eating just about anything from 300 to 400 calories would be better than nothing at all.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers found that those who don’t have breakfast have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,”I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
小題1:The word “l(fā)eftovers” in Paragraph 1 probably means __________.
A．pizza topped with fruitB．things left undone
C．food remaining after a mealD．meals made of vegetables
小題2:According to the last paragraph, it is important to__________.
A．be careful about what you eatB．eat something for breakfast
C．heat up food before eating itD．eat calorie-controlled food
小題3:What can we infer from the text?
A．Many people have wrong ideas about breakfast.
B．Working women usually have breakfast in a hurry.
C．There are some easy ways of cooking a meal.
D．Eating vegetables helps save energy.
小題4:The text is written mainly for those__________.
A．who go to work earlyB．who go to bed late
C．who eat before sleepD．who want to lose weight
小題5:What does the author advise the readers to do?
A．Better eat up all the food at dinner in the night.
B．Better eat less in the night.
C．Better eat leftovers in the morning.
D．Better get up late and eat nothing in the morning in order to burn more calories.

Salt plays an important role in our daily diet. Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict -how just three grams less a day would affect heart disease in the United States.
The result: Thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings. Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams,or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University. Each gram of salt contains four hundred milligrams of sodiu(鈉), which is how foods may list their salt content．
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative.The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows that the calorie information on the menu can influence what parents order for their children. Ninety-nine parents of three to six year olds took part. Half had calories between the two groups for foods that the parents would have chosen for themselves. McDonald's menus clearly showing how many calories were in each food. Parents given the counts chose an average of one hundred two fewer calories when asked what they would order for their children. Yet there was no difference in calories between the two groups for foods that the parents would have chosen for themselves.
Study leader Pooja Tandon says even small calorie reductions on a regular basis can prevent weight gain over time.The study was published in the journal Pediatrics．
小題1:Which of the following benefits does less salt diet in the passage NOT cover?
A．The decrease of strokes B．The prevention of weight gain
C．Fewer heart attacksD．The drop in medical care cost
小題2:It can be inferred from the passage that _______.
A．Americans ate no more than 5 grams of salt per day in the 1970s
B．the American Heart Association suggests less than 3 grams of salt a day for everyone
C．the less salt one eats, the healthier he will be
D．a(chǎn)ll the heart diseases result from eating too much salt
小題3:The National Salt Reduction Initiative aims to_______.
A．inform people of the harm that salt does to health
B．a(chǎn)ttract the public attention to the problem
C．require fast food places to list salt information
D．put pressure on food companies and restaurants
小題4:The underlined sentence "Yet there was no difference in calories between the two groups for foods that the parents would have chosen for themselves." implies that _______.
A．Parents pay less attention to the amount of calories in their diet.
B．Parents set a good example to their children in daily diet.
C．Parents take less salt than before while taking meals.
D．Most parents are on a diet for their health.

The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香氣). From air fresheners to scented (有香味的) candles, we live in a world of scent.
Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (過(guò)敏), headaches and asthma (哮喘) .
One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (濕疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.
“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”
People with pre-existing eczema are particularly vulnerable (易受影響). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.
And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.
“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”
小題1:What is the text mainly about?
A．The world trend of using fragrance.
B．The benefits of using non-fragranced products.
C．The health problems caused by fragrance
D．The ways of removing allergy.
小題2:According to Dr. Baron,            .
A．our bodies have an immediate reaction to fragrance.
B．seven in ten have suffered fragrance allergy.
C．fragrance can affect people who don’t have allergy
D．people can avoid contacting with fragrance easily
小題3:Which of the following questions does the text NOT answer?
A．Which products contain fragrance?
B．What’s the influence of fragrance in the air?
C．What are the air fresheners made up of?
D．How are headaches caused by fragrance?
小題4:The following paragraph might discuss            .
A．the asthma caused by strong scents.
B．people’s efforts to protect fresh air.
C．the methods of curing eczema
D．the bad effects of air fresheners.

Over the years, Americans have become used to salt．Most people have no idea how much salt they consume-on average, about 9 to 12 gram per person per day, according to the American Heart Association．That's twice the amount recommended by the government．
A new study last week showed eating even a little less salt could greatly help the heart．The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes（中風(fēng)）, four percent fewer deaths and eleven percent fewer new cases of heart disease．
Researchers also found that the benefits would be greatest for African Americans and women．As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr.Kirsten Bibbins-Domingo, an epidemiologist（流行病學(xué)家）at the University of California, San Francisco．Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%．A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%．
They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt．
However, other scientists say such a campaign is an experiment with the health of millions of people．
Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure．But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes．
“Salt has other biological effects． Calling for reductions in the national diet could have good effects, as well as harmful results． There is not enough evidence either way,”said Michael Alderman．
小題1:Eating too much salt may lead to the following EXCEPT           ．
A．strokeB．heart diseaseC．high blood pressure D．lung cancer
小題2:What can we learn from the passage?
A．Most Americans take more salt than advised．
B．African women eat more salt than Americans．
C．One's origin determines how much salt he can eat．
D．Good health is just on the basis of having less salt．
小題3:The author's attitude toward the study is         ．
A．coldB．objectiveC．subjectiveD．doubtful
小題4:What's the best title of the passage?
A．The Benefits of Eating Less Salt．
B．A New Study on Salt and Diseases．
C．An Argument Over Salt and Health．
