The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives – almost entirely for the better. But there’s a byproduct to that growth, one that’s evident – or sometimes less than evident – in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it’s taking a major toll (傷亡人數(shù),代價(jià)) on global health.
How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (內(nèi)燃發(fā)動(dòng)機(jī)煙霧) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and from the enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排氣凈化器) that reduce automobile emissions. Governments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (無鉛燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in care ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, witch is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
【小題1】What tends to give rise to the highest death toll according to the passage?

A.The lack of tight environmental protection standards.
B.The increasing numbers of the diesel cars and trucks.
C.The frighteningly high death rate from deadly cancer.
D.The world’s serious air pollution such as soot and dust.
【小題2】The “byproduct” (Paragraph 1) most probably refers to     .
A.consequence B.solution C.reform D.design
【小題3】The basic reason why so many people die from air pollution is that       .
A.the diesel soot is too small to be seen
B.the diesel soot is much too poisonous to breathe
C.the diesel soot roots in lungs and gets into blood
D.the diesel soot can also contribute to deadly cancer
【小題4】According to the passage, the writer actually wants to convince the readers that        .
A.the global economic growth is mainly to blame for air pollution and climate change
B.the developing countries are repeating the same mistakes as the developed ones made
C.the ecological situation and air pollution in India are becoming worse and worse
D.the unbeatable air is increasingly becoming a major killer throughout the world
【小題5】By describing urban design as “the best solution” in the last paragraph, the writer means that        .
A.the making of tougher environmental regulations alone is of little use
B.more sever regulations should be made to handle air pollution
C.the urban construction in western developed countries is the best choice
D.the pace of development has to be slowed down to reduce air pollution

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough.
After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?
The photograph of me taken the day I started this trial demonstrates(展示)perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster(光澤). It looks dead. Even my lips look shriveled(枯萎的). This is all classic evidence of poor hydration, apparently.
Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste.
Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing.
【小題1】Which statement is Not True according to Paragraph 1?

A.The author drinks about a liter of liquid every day.
B.The author has something in common with a camel.
C.The author thinks she drinks enough water every day.
D.The author actually has plenty of water in her daily life.
【小題2】Why did the author decide to drink the recommended amount of water?
A.Because she was very fond of doing experiments.
B.Because she was informed of the importance of drinking enough water.
C.Because her doctors forced her to do it.
D.Because she wanted to be cured of her stomachache.
【小題3】The author’s lack of hydration caused the following physical responses Except_______.
A.shriveled lips
B.enough luster of her skin
C.dark shadows around her eyes
D.wrinkles and blotches on her face
【小題4】According to the passage, the author most probably tends to tell us_________.
A.the more water one drinks, the healthier he is

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined 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 obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, 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 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 tract 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(惡性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) 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.
【小題1】What is the main purpose of this passage?

A.To advocate eating more raw and whole foods. 
B.To tell the differences between raw and processed foods. 
C.To inform people of the harm of processed foods. 
D.To warn people of the problem of obesity. 
【小題2】It can be inferred from Para. 2 that ________.
A.it is essential for people to protect their vital organs 
B.foods with natural enzymes help people keep fit 
C.we’d better be cautious about raw and whole foods  
D.giving up cooked and refined foods is a new lifestyle 
【小題3】Processed foods are unhealthy because they __________.
A.destroy body’s cells B.a(chǎn)re difficult to digest 
C.may lead to obesity D.stop body’s metabolism 
【小題4】What is likely to be talked about following the last paragraph?
A.Active approaches to avoid acid. 
B.Different causes of acid accumulation. 
C.Correct ways to cook raw foods. 
D.Suitable types of raw and whole foods. 
【小題5】What can we learn from the text?
A.Processed foods are good for our appetite mechanism. 
B.Eating the right types of raw and whole foods does good to our body. 
C.The accumulation of acid in the digestive tract makes digestion more effective. 
D.Processed foods also comfort the digestive tract.

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift(輪班)work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (藥物治療) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
【小題1】The purpose of the text is to_____ .

A.persuade workers to have a good sleep
B.a(chǎn)dvise night workers to keep healthy
C.encourage workers to do day work
D.help night workers to sleep well

A.A suitable amount of alcohol to help sleep.
B.A regular life on weekday’s and weekends.
C.A bright room without phones to sleep in.
D.A break for sleeping anytime during the day.
【小題3】On which condition should a person turn to a sleep specialist for help?
A.If he suffers from a sleep disorder for the first time.
B.If a good sleep environment is greatly needed for him.
C.If he fails to get quality sleep through his own efforts.
D.If he has the problem of falling asleep in the daytime.
【小題4】We can learn from the text that_____________.
A.night workers need a long time to fall asleep

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Bikingk3s5u
* Elliptical Training (橢圓運(yùn)動(dòng))
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics(肌肉增強(qiáng)訓(xùn)練)
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates(普拉提課程)
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
【小題1】If your purpose is to _______, you can choose swimming as your exercise form.

A.build a strong and healthy heart
B.keep muscles and bones strong
C.keep body flexible
D.reduce risk of injuries and pain in joints and muscles
【小題2】After reading this passage, we know that ________.
A.Yoga is really better for people than running
B.The more exercise you do, the better
C.Flexibility training helps you build up your muscles
D.The three kinds of training have links with one another
【小題3】Which of the following is closest in meaning to “session” in Paragraph 3?
A.meetingB.gatheringC.periodD.term
【小題4】The paragraph following this article may discuss_______.
A.how to find a good workout dealing with two or three of these goals
B.how to choose an exercise type
C.how to build up our strength
D.how to be more flexible

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device of such products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability.
Often such products are nothing more than money-making things for their promoter. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food Drug Administration)can require proof (證明)under the Food, Drug, and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action ,including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律訴訟), and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
【小題1】It can be inferred that ads mentioned in the text are ______.

A.objective B.costly C.unreliable D.illegal
【小題2】Which of the following is true according to the text?
A. The court is in charge of removing dangerous product.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.
【小題3】FDA can ask for the proof of safety and effectiveness of a product ________.
A.if it is a drug
B.if it is a device
C.if its consumers make complaints
D.if its distributors challenge FDA’s authority
【小題4】The Relaxacisor is mentioned as_______.
A.a(chǎn) product which was designed to produce electricity
B.a(chǎn) product whose distributor was involved in a legal case
C.a(chǎn) successful advertisement of a beauty product
D.a(chǎn)n example of a quality beauty product
【小題5】 The author intends to __________
A.make consumers aware of the promoters’ false promises
B.show the weakness of the law on product safety
C.give advice on how to keep young and beautiful
D.introduce the organization of FDA
