Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. It is made of sodium (鈉) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work.
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (腎) problems.
If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips:
*Cut back on high salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often.
*Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt.
*Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals.
小題1:Many people in China don’t realize they are eating too much salt because ______.
A．salty food tasted better than reduced salt food
B．they do not calculate the amount of salt they eat
C．a(chǎn)bout 3/4 of the salt we eat is already in the food we buy
D．few people experience problems from eating too much salt
小題2: For a healthier life, the author’s suggestion is to ________.
A．cut back on food with less salt
B．eat less heavily salted food
C．eat as much reduced salt bread as is wanted
D．stop eating bread and breakfast cereals

A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air.
China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both particulate pollution of the air and life expectancy in the two regions.
While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the researchers, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of 一Technology. "This study provides a unique setting to answer the life expectancy question because the(heating) policy dramatically changes pollution concentrations（含量），，，Greenstone said in an email. "Further, due to the low rates of migration in China in this period, we can know people's exposure over long time periods," he said.
The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Riv饑which divides China into north and south. It was in effect for much of the 1950-198,0 period of central planning, and, though discontinued after 1980, it has left a legacy（遺留） in the north of heavy coal burning, which releases particulate pollutants into the air that can harm human health. Researchers found no other government policies that treated China's north differently from the south.
The researchers collected data for 90 cities, from 1981 to 2000, on the annual daily average concentration of total suspended（懸浮的）particulates. In China, those are considered to be particulates that are 100 micrometers or less in diameter, sent out from sources including power stations, construction sites and vehicles. Among them, PM2.5 is of especially great health concern because it can go deep into the lungs.
The researchers estimated the impact on life expectancies using death data from 1991-2000． They found that in the north, the concentration of particulates was 184 micrograms per cubic meter一or 55 percent higher than in the south, and life expectancies were 5.5 years lower on average across all age ranges.
小題1:The main idea of this passage is that＿·
A．research in China finds air pollution shortened life expectancy
B．the government provided free coal for heating in North China
C．coal burning causes bad air quality across China
D．a(chǎn) new study finds different particulates in South China
小題2:According to Greenstone,＿greatly contributed to the high pollution concentrations in North China.
A．power stationsB．construction sites
C．the free heating policyD．gases from vehicles
小題3:It is implied in the passage that＿·
A．coal is no longer used for heating in North China
B．a(chǎn)ir quality was comparatively better in South China
C．southerners burned coals for heating in the 1980s
D．people preferred to live in South China after 1980
小題4:The underlined word "particulates" most probably means＿．
A．dirty cloudsB．particular smoke
C．harmful dustD．dangerous bacteria

Walking is the exercise of choice for most dieters. You don't need a gym membership to do this effective exercise. Here's how to prepare:
The only equipment you really need is a decent pair of walking shoes. What matters most is comfort. When you're shopping for shoes:
●Wear the socks you plan to exercise in. That way you'll get the best fit.
●Try on both shoes. Most people's feet aren't exactly the same size. Choose a pair that fits your larger foot.
●Allow a little extra room. Feet swell when you walk, so buy a pair with about a thumb's width between your longest toe and the toe of the shoe.
Sure, walking comes naturally. But the following tips will help you stay comfortable and get the most out of your walk:
●Look ahead. Keep your neck straight and your head held high. If you have to look down to see where you're going, lower your eyes, not your head.
●Move both arms. Let your arms swing naturally at your sides, and you'll burn up to 15 percent more calories by keeping your arms moving.
●Don't carry unnecessary weight. Some people try to get in extra exercise by carrying a couple of light dumbbells(啞鈴), but fitness-walking experts say that's risky: The weights can pull you off balance and tighten muscles in your back or legs.
Walking is one of the safest activities. Still, the following tips may be helpful:
●If you're walking at night, wear a piece of reflective clothing.
●If the path is dimly lit, bring a good flashlight.
●When the weather's hot, be sure to drink some water before you set out and better take a bottle of water with you if you plan to walk quite a long time.
●If your path is rough, protect your ankles. Consider wearing a comfortable bandage for support.
小題1:According to the text, which of the following is correct?
A．Wearing a piece of reflective clothing can make you look smart.
B．Moving both arms while walking can help you lose more weight.
C．You should buy shoes with a little extra space for your smaller foot.
D．Losing weight by walking is always easy and effective without any danger.
小題2:What are possibly necessary if you walk through our town and then up a hill along a winding path on a hot evening?
a. good walking shoes      b. reflective clothing         c. light dumb-bells
d. a flashlight            e. a bandage                  f. a bottle of water
A．a(chǎn), b, c, d, e, fB．a(chǎn), c, d, e, fC．a(chǎn), b, d, e, fD．a(chǎn), d, e, f
小題3:What can be inferred about the author of the text?
A．He/She once got his/her legs injured while walking carrying light dumb-bells.
B．He/She might live in a small town with dimly lit streets.
C．He/She needs just a decent pair of walking shoes while walking.
D．He/She is quite experienced in the exercise of walking.

Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was long­lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ.Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first­time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary，Mary Ruebush，an American immunologist(免疫學家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
小題1:The kings of France and England in the 16th century closed bath houses because ________.
A．they believed disease could be spread in public baths
B．they thought bath houses were too dirty to stay in
C．they lived healthily in a dirty environment
D．they considered bathing as the cause of skin disease
小題2:Which of the following best describes Henry IV's attitude to bathing?
A．Approving. B．Afraid.C．Curious.D．Uninterested.
小題3:How does the passage mainly develop?
A．By providing examples.
B．By making comparisons.
C．By following the order of importance.
D．By following the order of time.
小題4: What is the author's purpose in writing the passage?
A．To stress the role of dirt.
B．To introduce the history of dirt.
C．To present the change of views on dirt.
D．To call attention to the danger of dirt.

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
小題1:The underlined word is best replaced by __.
A．InjureB．BenefitC．PushD．Shape
小題2:What does author mainly want to tell us in the 3rd paragraph?
A．All physical activities are equally harmful.
B．Yoga causes much less injuries than other physical activities.
C．Similar researches have been done before.
D．Yoga, like any other form of exercise, can hurt people.
小題3:Which is not mentioned among the reasons for yoga being likely to cause injury?
A．Teachers lack the knowledge of students’ limits.
B．Modern lifestyle decreases our flexibility.
C．The body doesn’t tell when you are in real pain.
D．Students themselves might not be in good physical condition.
小題4:What is the author’s attitude towards practicing yoga?
A．It’s a shame not to practice yoga.
B．One should push the limits in order to be perfect.
C．The majority should give up yoga for it may cause harm.
D．One should enjoy the physical and mental benefit that yoga brings.

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
* Biking
* Elliptical Training (橢圓運動)
* 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（肌肉增強訓練）
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

What time of day can you think most quickly? Are you a morning person? Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.
Many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help your body’s temperature rise quickly.
But everyone’s body clock is different and some are special. Morning people will get up early and
work better early in the day. Evening people will work later but work better towards the end of the day. Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day. 
Between noon and 4 pm, people begin to pay less attention. This is because we think less quickly
after a big meal. Research also shows we become sleepy around 2 pm. This is why people in Spain take a short sleep in early afternoon.  Finally, it is best to eat when we’re active. This allows our body
to burn calories better and stops our blood sugar levels from getting too high.
小題1:__________ can tell us what time of day we can perform best at.
A．Morning peopleB．A warm shower
C．Our body temperature.D．Our body clock
小題2:A morning people will ________.

小題3:What is the best time for physical performance? 
A．Between 3 pm and 6 pmB．Between 7 pm and 10 pm.
C．Between noon and 4 pmD．Between 5 pm and 8 pm.
小題4:Why is it best to eat when we’re active? 
A．Because eating makes the brain unable to think quickly.
B．Because it makes our blood sugar levels higher.
C．Because our body can burn more calories.
D．Because we are allowed to eat then.
小題5:What is the best title for this article? 
A．How can we work better
B．The best time to exercise
C．How can we keep healthy
D．The perfect time to do something

[1] Scientist proves better busy than doing nothing, research has found. Keeping the mind occupied with tasks—no matter how meaningless—keeps off negativeemotions, the study found.
[2] However, the bad news is that humans seem born to be lazy in order to save energy, according to Professor Christopher Hsee, a behavioural scientist at Chicago University.
[3] In a study 98 students were asked to complete two surveys. After they had completed the first they were made to wait 15 minutes to receive the next one. They were given a choice of either handing in the first survey nearby or at a more distant location they had to walk to. Whichever choice they chose, they received a chocolate bar. Two-thirds (68 per cent) chose to take a shortcut. Those who had taken the walk reported feeling happier than those who had stayed put. Prof Hsee concluded __________________ helped keep people happy.
[4] He said the findings, reported in the journal Psychological Science, had policy guidance. "Governments may increase the happiness of idle（閑散的）citizens by having them build bridges that are actually useless", he suggested.
[5] At the individual level, he advised: "Get up and do something. Anything. Even if there really is no point to what you are doing, you will feel better for it." He added, "By the way, thinking deeply or busy with self-reflection counts as keeping busy, too. You do not need to be running around—you just need to be busy, either physically or mentally."
