develop rock-hard abdominal muscles(腹肌). It"s easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch those unwanted inches leave your waist. Americans spend tens of millions of
dollars on various products to firm up their fat around the waist. And did they work? Not necessarily.
Independent studies have concluded that most of these products ---- no matter who approved them or
how expensive they are ---- shape your midsection no better than old-fashioned stomach crunches(仰卧起坐). Some can even cause injury ---- like the $518.99 Body Shaper-Q8SP, which left electrical burns on some researchers at the University of Wisconsin, La Crosse. Others, like the popular Ab-Doer,
typically burn less energy than a gentle walk, according to a study to be published in September by the
American Council on Exercise.
The fact is that many Americans don"t have the biological makeup to develop an obvious abdominal
muscles. They are either unable to get the necessary muscle mass or they can"t lose enough fat to make a
difference. Even if the underlying muscles are well developed, all it takes to hide it is one-sixteenth of an
inch of fat. That"s enough to exclude most healthy women as well as plenty of guys who do crunches
every day.
So what works best? In its new study, the exercise experts researched on the results of the popular
Ab-Doer. A lengthy TV advertisement promises that just 10 minutes a day performing such movements
as "Body Boogies" and "Good Mornings" will "help form those muscles the fun and easy way without
diets." Steven Loy, professor at California State University, Northridge, tested the promise by measuring
the electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his
colleagues then compared the results with those produced during traditional exercises. They determined
that the muscles were no more active, and in some cases less so, when exercisers were using the Ab-Doer.
Taking a broader approach, researchers at San Diego State University compared 13 abdominal
exercises for their ability to develop the central abdominal muscles. They concluded, in a report published
in May, that the most effective exercises kept turning the body and worked the muscles the entire time.
Among the winners: the bicycle movements ---- so called because it looks as if you are riding a bike
while lying flat on the floor ---- and exercises performed on the "Captain"s Chair", a product typically
found in gyms that helps hold the body in the air while you raise your legs up toward your chest.
Researchers suggested that a varied routine of the different exercises could deliver the best results.
B．Ab-Doer.
C．Captain"s Chair.
D．Body Shaper-Q8SP.
because .
B．injuries interrupt their exercise frequently
C．they change their exercise routine regularly
D．how big their muscles will be is determined by birth
B．offering professional suggestions
C．presenting findings of researches
D．comparing advertisements of products
B．To promote proven exercise techniques and to advise against false advertisements.
C．To indicate that diet and exercises are necessary factors for a fit midsection.
D．To sponsor rich healthy lifestyle based on advanced product research.

| 阅读理解 The World Health Organization says obesity rates are rising in Pacific island countries.So, too, are health problems linked to being overweight. The WHO says a major reason for the rising obesity rates is an increase in imported foods.It says many Pacific islanders have replaced their traditional diets of vegetables and fruits with imported processed foods. Dr.Temu Waqanivalu is with the World Health Organization"s South Pacific office in Suva, Fiji.He says many of the imported products lack nutritional value. Temu Waqanivalu said:"In some of the places, you"d be amazed to see how a bottle of Coke is cheaper than a bottle of water.I think that represents the kind of offenvironment we"ve created that doesn"t really encourage or make lifestyle choices an easy choice for the population." And a lack of physical activity among many Pacific islanders only adds to the obesity problem. The WHO says more than 50 percent of the population is overweight in at least ten Pacific island countries.The rate is as high as 80 percent among women in the territory of American Samoa.Fiji had the lowest obesity rate at 30 percent. In all, almost ten million people live in Pacific island countries.The WHO estimates that about 40 percent of them have health disorders related to diet and nutrition. Diabetes rates are among the highest in the world.Fortyseven percent of the people in American Samoa have diabetes.So do 44 percent of the people in Tokelau, a territory of New Zealand. By comparison, the diabetes rate is 13 percent in the United States, a country that has its own problems with rising obesity. Officials also note an increase in nutritional problems like anemia and not enough vitamin A in the diets of Pacific islanders.Dr.Waqanivalu says treating conditions related to obesity and diet puts pressure on limited health resources and budgets. 1. The main reason why obesity rates are rising in many Pacific islanders is ________. A. the change of society B. the change of eating habits C. the change of life style D. lack of exercise 2. Imported products lack nutritional value but people love to buy them because ________. A. they are cheap B. they are popular C. they are tasty D. they are convenient to get 3. How many people living in Pacific island countries have health disorders? A. 1 million. B. 4 million. C. 6 million. D. 10 million. 4. The percentage of diabetes rates in American Samoa is ________. A. optimistic B. steady C. worrying D. low 5. If the passage appears in a newspaper, which column will it be? A. Science. B. Nature. C. Entertainment. D. Health. | |

| Elderly adults who regularly drink green tea may stay more active and independent than their peers over time,according to a Japanese study that covered thousands of people． Green tea contains antioxidant chemicals that may help ward off the cell damage that can lead to disease．Researchers have been studying green tea"s effect on everything from cholesterol(胆固醇)to the risk of certain cancers,with mixed results so far． For the new Japanese study,researchers decided to examine the question of whether green tea drinkers have a lower risk of frailty and disability as they grow older． Tomata and his colleagues followed nearly 14,000 adults aged 65 or older for three years． They found those who drank the most green tea were the least likely to develop "functional disability", or problems with daily activities or basic needs,such as dressing or bathing． Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups a day． The study did not prove that green tea alone kept people active as they grew older． Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education．lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness． They also tended to be more socially active and have more friends and family to rely on． Although it"s not clear how green tea might offer a buffer(缓冲剂)against disability,Tomata"s team did note that one recent study found green tea extracts(提炼物)seem to increase leg muscle strength in older women． While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could block drugs that prevent blood thickened． | |

| 阅读理解 China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota"s hybrid car Prius will be ready to drive in China this week. Let"s have a look at the new car. Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed. Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car"s gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off. The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go. The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car"s batteries will last for around 200,000 miles. 1. The author writes this passage mainly to________. A. teach people how to drive a hybrid car B. introduce a new kind of "green" car C. show how to save their gasoline when driving a car D. announce plans to develop hybrid vehicles for China 2. The first sentence probably refers to ________. A. there will be more and more green land in China B. China is still young and lacking experience C. China"s new cars are combinations of different green models D. China has started producing environmentally friendly cars 3. Which of the followings is NOT true? A. The hybrid cars reduce air pollution and oilshortages. B. The car"s gasoline engine doesn"t work until it reaches about 24 km/h. C. This kind of car is completely controlled by an onboard computer. D. A specially designed battery motor provides extra power when needed. 4. What is the most important feature of hybrid cars? A. They are powered by both a rechargeable battery and gasoline. B. They are much quieter than traditional cars. C. They only use 99 percent of their power to run up hills. D. They have smaller engines than traditional gasoline ones. 5. What can we conclude from the story? A. The batteries can be recharged at any time you want. B. Using the brake suggests that the gasoline engine should work. C. The batteries will last for 200, 000 miles without being recharged. D. The gasoline engine charges the batteries as well as powers the car. | |
| 阅读理解 Malaria, the world"s most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year-almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don"t (or can"t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long. Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn"t kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease"s spread is due to global warming. For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next. 1. According to paragraph 1, many people don"t seek care because ________. A. they are too poor B. it is unusual to seek care C. they can remain unaffected for long D. there are too many people suffering from the disease 2. People suffering from malaria ________. A. have to kill female mosquitoes B. have ability to defend parasites C. have their red blood cells infected D. have sudden fever, followed by chills 3. Which of the following may be the reason for the wide spread of the disease? A. Its resistance to global warming. B. Its ability to pass on the virus frequently. C. Its outbreaks in cities with large populations. D. Its ability to defend itself and resist new drugs. 4. It can be inferred from the passage that ________. A. no drugs have been found to treat the disease B. the alternative treatment is not easily available to most people C. malaria has developed its ability to resist parasites D. nobody knows what will be the drug to treat the disease |
