Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中風(fēng)）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
小題1:The text mainly discusses the relationship between       .   
A．heart problems and air quality
B．heart problems and exercising
C．heart problems and smoking
D．heart problems and fatty food
小題2:The underlined word “modest” in Paragraph 3 most probably means   .

C．relatively lowD．extremely high
小題3:What can we learn from the text?  
A．Eating fatty food has immediate effects on your heart.
B．The EPA conducted many studies on air quality.
C．Moderate air quality is more harmful than smoking,
D．Stricter regulations on pollutants should be made.
小題4:The author’s purpose of writing the text is most likely to        .
A．informB．persuade C．describe D．entertain

小題1:A
小題2:C
小題3:D
小題4:A

Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experi­ment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite to(與.....相反) what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
小題1:During the test, those who were tested were given ________.
A．no breakfast at all
B．very rich breakfast
C．little food for breakfast
D．different breakfast or none
小題2:The results of the test show that ________.
A．breakfast has great effect on work and studies
B．breakfast has little to do with a person’s work

Good health is the most valuable thing a person can have, but one cannot take good health for granted（認(rèn)為……理所當(dāng)然）. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (營養(yǎng)) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat.

If you follow a regular exercise program, you will probably increase your life-span (壽命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples.

Long ago, operation usually had to be done while the sick man could feel everything. The sick man had to be held down on a table by force while the doctors did their best to save him. He could feel all the pain if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.
Soon after 1770, Josept Priestley discovered a gas which is now called “l(fā)aughing gas”. Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn’t seem to feel pain when they were using this gas. He decided to make an experiment on himself．He asked a friend to help him．
Wells took some of the gas, and his friend pulled out one of Wells’ teeth. Wells felt no pain at all.
As he didn’t know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out. 
Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.

In 2030, 42 percent of American adults will be obese, and about one-quarter of that group will be severely obese, a condition that shortens life and wastes large medical expenses, a new study predicts.
Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.
小題1:The word “ailments” in the second paragraph is equal to _______.
A．DiabetesB．Heart diseaseC．Kidney failureD．Diseases

In 1955, a man named Raymond Kroc together with two brothers named McDonald opened a popular restaurant in California which sold food that was easy to prepare and serve quickly. Hamburgers, French fries, and cold drinks were the main food there. Kroc opened similar eating places under the same name, “McDonald’s”, and they were an instant success. He later took over the company, and today it is one of the most famous and successful “fast-food” in America and around the world.
Why was his idea successful? Probably the most important reason was that his timing was right. In the 1950s, most married women stayed home to keep house and take care of their children. In the 1960s, many women returned to the workplace. This meant that they had less time or energy to prepare meals, so they spent more on “ TV dinners ” and fast-food restaurants. Single parents also have little time to spend in the kitchen. People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth.
Fast-food is not part of the diet of all Americans. Another trend of the 1960s, sometimes called the back-to-nature movement influenced many people to avoid food that was packaged (包裝) or processed(處理). This preference for natural food continued to this day.
From the success of Raymond Kroc’s fast-food business, we can say that social economic trends influence where and what we eat.
小題1:The underlined sentence “Cooking for one is often more trouble than it is worth” means that ______.
A．cooking for some people is worth more money
B．it is not worthwhile to take too much time to cook for one person
C．there are more problems when one person cooks
D．cooking for one person cost more money
小題2:Para 3&4 seem to imply (暗示) that ________.
A．many married women began to work in the 1960s
B．natural foods are still popular today
C．fast food is not part of the diet of all Americans
D．divorce (離婚) causes people to change their eating habits
小題3:Which of the following is NOT the reason for McDonald’s success?
A．people living alone tend to depend on fast food
B．single parents have little time to spend in the kitchen
C．many women returned to the workplace in the 1960s
D．Kroc chose the “Mc Donald” brothers as his partners
小題4:The main purpose of the passage is to tell us________.
A．Raymond Kroc is the most successful fast-food business owner in the world
B．social and economic changes affect eating habits
C．fast-food is easy to prepare and serve quickly
D．Americans eat either fast food or natural food

Eating a diet high in processed food(加工食品)increases the risk of depression，research suggests．What's more，peopie who ate plenty of vegetables，fruit and fish actually had a lower risk of depression，the University College London team found．
Data on diet among 3，500 middle-aged civil servants(公務(wù)員)were compared with their emotional state five years later，a British journal reported．They split the participants into two types of diet--those who ate a diet largely based on whole food，which inc!udes lots of fruit， vegetables and fish，and those who ate a mainly processed food diet，such as sweetened desserts，fried food，processed meat，refined grains and high fat dairy products After accounting for factors such as gender，age，education，physical activity，smoking habits and chronic(慢性的) diseases，they found a significant difference in the future depression risk with the different diets．
Those who ate the most wholefood had a 26％ lower risk of future depression than those who ate the least wholefood．By contrast，people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods．
Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for．
There was a paper showing a Mediterranean diet was associated with a lower risk of depression，but the problem with that is if you live in Britain，the likelihood(可能性)of you eating a Mediterranean diet is not very high．
Dr．Andrew McCulloeh，chief executive of the Mental Health Foundation，said，this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health．

Coffee experts are willing to pay large sums of money for high-quality coffee beans. The high-end beans, such as Kona or Blue Mountain, are known to cost extraordinary sums of money. Then there is Kopi Lowak (translated as “Civet Coffee”), the world’s most expensive coffee, which sells for as much as US $50 per quarter-pound.
This isn’t particularly surprising, because approximately 500 pounds a year of Kopi Lowak make up the entire world supply. What is surprising is why this particular coffee is so rare. In fact, it’s not the plants that are rare. It’s the civet droppings. That’s right, the civet droppings—the body waste of the palm civet. Coffee beans aren’t Kopi Lowak until they’ve been digested(消化) and come out in the body waste of the palm civet.
Palm civets are tree-dwelling, raccoon-like little animals, native to Southeast Asia and the Indonesian islands. They also have a love for coffee cherries. According to Kopi Lowak suppliers, palm civets eat the fruit whole, but only digest the outer fruit, leaving the beans intact(完好無損). While the beans are not destroyed, they undergo a transformation in the animal’s body. A chemical substance in the digestive system of the palm civet causes some changes to the beans to give them a unique flavor(味道). However, this is not the only explanation why coffee beans retrieved from civet droppings have a special flavor all their own. Another possible reason is that palm civets have an unfailing instinct for picking the coffee cherries at the peak of their ripeness.
Kopi Lowak is reported to have a character in taste unlike any other coffee, complex with caramel undertones and an earthy flavor. Currently, most of the world’s supply of Kopi Lowak is sold in Japan, though a few US markets are also starting to stock up on Kopi Lowak.
小題1:What does “This” in the second paragraph refer to?
A．Civet Coffee.B．Blue Mountain coffee.
C．The high price of Kopi Lowak.D．The unique taste of Kona.
小題2:Why is Kopi Lowak expensive?
A．There is a very limited supply of the beans.
B．The coffee trees that grow the beans are scarce.
C．It takes a long time for the coffee beans to ripen.
D．Only a few experts know how to produce the beans.
小題3:What is the main point discussed in the third paragraph?
A．Why palm civets like the coffee beans.
B．Where Kopi Lowak is mainly harvested.
C．What chemicals are found in the civet’s digestive system.
D．How palm civets change coffee fruit to Kopi Lowak beans.
小題4:Which of the following statements is true, according to the passage?
A．Little palm civets eat only the outer layer of the coffee cherries.
B．Palm civets somehow know the right time when the coffee fruit ripens.
C．Kopi Lowak is most popular in Southeast Asia and the Indonesian islands.
D．Kona and Blue Mountain are the most expensive coffees but only of average quality.

I’m fat. I’m too skinny. I’d be happy if I were taller, shorter, had curly hair, straight hair, a smaller nose, bigger muscles, longer legs. Do any of these statements sound familiar? Do you often put yourself down? If so, you’re not alone. As a teen, you’re going through a ton of changes in your body. And as your body changes, so does your image (形象) of yourself. Lots of people have trouble getting used to it and this can affect their confidence.
Some people think they need to change how they look or act to feel good about themselves. But actually all you need to do is change the way you see your body and how you think about yourself.
The first thing to do is recognize that your body is your own, no matter what shape, size, or color it comes in. If you’re very worried about your weight or size, go to your doctor to check that things are OK. But it’s no one’s business but your own what your body is like—finally, you have to be happy with yourself.
Next, find which aspects (方面) of your appearance you can change and which you can’t change and need to accept—like their height, for example, or their shoe size.
If there are things about yourself that you want to change and can do this by making goals for yourself. For example, if you want to get fit, make a pan to exercise every day and eat nutritious foods.
When you hear negative comments coming from within yourself, tell yourself to stop. Try building your confidence by listing three things in your day that really gave you pleasure. It can be anything like the way the sun felt on your face, the sound of your favorite band, or the way someone laughed at your jokes.
小題1:From the first paragraph, we can infer that           .
A．many teens can’t accept their body change easily
B．most teens like to have a special body image
