Bean and other seed shoots are also known as sprouts (新芽). The dry bean seeds contain a store of nutrients just waiting to be released when they sprout. Under the right conditions they will germinate (发芽)。 As they grow, the food value of the seeds is multiplied into vitamins, minerals (矿物质) and other nutrients. This happens almost overnight!
It is easy to grow your own sprouts, but you need to buy your seeds from supermarkets or health food stores. Seeds for planting in the garden are often powdered with chemicals, so when becoming sprouts they are not safe to eat.
Try growing sprouts from a variety of beans and seeds. You will find different sprouts at different stages. Bean sprouts are best when they are about three centimeters long. Wheat and sunflower sprouts taste best when the sprouts and the seeds are of the same length. If the sunflower sprout is too long it leaves a funny stinging feeling in the throat after eating. Alfalfa sprouts are best when their small leaves are well developed. Pea and soybean sprouts are good long or short.
If you leave your sprouts in filtered sunlight for a few hours, the leaves will turn green as chlorophyll (叶绿素) is added. Eating sprouts with green leaves benefits your blood, cells, and the digestive system.
【小题1】Which of the following sprouts taste good whether they are long or short?
| A.Soybean sprouts | B.Sunflower sprouts |
| C.Alfalfa sprouts | D.Wheat sprouts |
| A.increase | B.decrease | C.remain the same | D.lose |
| A.Long sunflower sprouts taste better than short ones |
| B.Eating too long sunflower sprouts will make you feel uncomfortable in the throat |
| C.Eating sprouts with green leaves will be harmful to your health |
| D.It takes a long time for the food value of the seeds to multiply |
| A.Sprouts of seeds for planting in the garden may not be safe to eat. |
| B.Alfalfa sprouts taste best when their small leaves are more fully grown. |
| C.All sprouts taste best during the early stage of their growth. |
| D.Sunlight will make the leaves of sprouts green. |
Air travel is such an everyday experience these days that we are not surprised when we read about a politician having talks with the Japanese Prime Minister one day, attending a meeting in Australia the following morning and having to be off at midday to sign a trade agreement in Hong Kong. But frequent long-distance flying can be so tiring that the traveler begins to feel his brain is in one country, his digestion(消化吸收)in another and his powers of concentration nowhere---in short, he hardly knows where he is.
Air travel is so quick nowadays that we can leave London after breakfast and be in New York in eight hours, yet what really upsets us most is that when we arrive it is lunch time while we have already had lunch on the plane and are expecting dinner.
Doctors say that air travelers are in no condition to work after crossing a number of time zones. Airline pilots, however, often live by their own watches.
【小题1】After a long air travel, a traveler _______.
| A.finds himself in a different world |
| B.finds his brain apart from his body |
| C.finds himself in Hong Kong the following morning |
| D.has little sense about where he is |
| A.they don’t trust others’ watches |
| B.they don’t change their watches |
| C.they make a living by their own watches |
| D.they do as they used to do |
| A.should rest when they arrive in New York from London. |
| B.should work in good condition since they just finish a long journey. |
| C.rest in a place with good condition. |
| D.give up long journey since it makes them tired. |
A super drug that could remove Alzheimer’s (老年痴呆症),heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.
【小题1】Some people are able to live to 100 years because of ______.
| A.a magical medicine | B.three special genes | C.good living habits | D.longevity proteins |
| A.Because it can bring great benefits to scientific labs. |
| B.Because it can help people change their unhealthy genes |
| C.Because it helps produce a drug that can make people live longer. |
| D.Because it will help scientists build up a new branch of biology. |
| A.longevity genes can create good cholesterol. |
| B.the volunteers share some common ancestors |
| C.bad habits are likely to have no effect on the volunteers |
| D.longevity genes protect the volunteers against bad habits |
| A.Positive | B.Negative | C.Critical | D.Cautious |
The world hash’t seen a pandemic(流行疾病)in 4 1 years,when the”Hong Kong”flu crossed the globe and killed about one million people worldwide.If H1N1 flu(甲型流感)reaches pandemic levels,what would happen next?
The outbreak of SA
RS in 2003 rang alarm bells as potential pandemics.Although it jumped the”animal-to·human”barrier,neither disease changed enough to enable human-to.Human infection.Strictly speaking,SARS did not become pandemics because it was too good at killing their hosts.For a pandemic,it needs to be able to maintain human-to.human contact without killing its host off.
”H1N1 flu is already a man-to-man disease,which makes it much more difficult to manage.
And H1N1 flu appears much more infectious than SARS.
But the WHO warns,it cannot say whether or not it will indeed cause a pandemic.According to experts,here’s what the world might see if there is another pandemic,based on past exp
erience.
The disease would skip from city to city over an 18-to-24 month period,infecting more than a third of the population.World health Organization officials believe as many as 1.5 billion people around the globe would seek medical care and nearly 30 million would seek hospitalization.Based on the last pandemic and current world population,as many as 7 million people could die.Hos
pitals will become overcrowded;scho
ols will close;businesses will close;airports will be empty.Business will become very bad,as people avoid as much social contact as possible.
Health facilities will become overrun with patients and there would be less-than-adequate staffing,as medical health professionals fall ill themselves and that would result in higher deaths.
The very young and very old will likely be the most susceptible(易受感染的)to the illness.Experts warn,much is still unknown about the current H1N1 flu virus and its severity and it is too early to say whether it will lead to a pandemic.Right now,the focus is on finding answers and controlling the spread.
【小题1】How many kinds of disease is mentioned in the passage?
| A.Two | B.Three | C.Four | D.Five |
| A.SARS didn’t change enough to enable sustained(持续的)human-to—human infection. |
| B.SARS was very good at killing its carriers. |
| C.A man with H1N1 flu can not infect another man easily. |
| D.Comparing SARS and H 1N 1 flu,SARS is not as infectious. |
| A.It spread all around the globe and killed lots of people. |
| B.It killed about millions of people. |
| C.It killed about one million people in Hong Kong. |
| D.Not the old but the young were susceptible to it and got killed. |
| A.The H1N1 flu will skip from city to city over an 18一to一24 month period. |
| B.Doctors and nurs |
| C.Every country is taking measures to stop the H1N1 flu from leading to a pandemic. |
| D.The WHO and experts have known much about the current H1N1 flu virus. |

America’s No.1 health problem?A report published by the American Institute of Stress claims the biggest threat to health today is neither cancer nor AIDS.The report says:“it
has been estimated that 75-90 percent of all visits to primary care physicians are for stress-related problems.’’
It is no exaggeration(夸张)to
say that people today are being attacked by stress.According to the National Consumers League,“Work is the top source of stress for adults who have problems and stress in their lives(39%).Other sources include health(10%),concern about the economy(9%)and concern about international conflict and terrorism(4%)”
However, stress is hardly unique to the United States A British survey in 2005 estimated that ‘‘over half a million individuals in Britain believed in 2004 that they were experiencing work-related stress at a level that was making them ill”.As a result of“work-related stress,depression or anxiety”, there are“an estimated thirteen and a half million reported lost working days per year in Britain”
The picture is no less bleak in mainland Europe. According to the European Agency for Safety and Health at Work.“work-related stress has been shown to affect millions of European workers across all types of employment sectors’’ One survey revealed that there are “about 41 million workers affected by work-related stress each year.”
What about Asia?A report issued by a conference held in Tokyo concluded,“Job stress is a common concern among many countries in the world,both developing and industrialized countries”.The report observed that“several countries i
n East Asia,including China and Korea, have rapidly industrialized and economically grown”.These countries now have a lot of concerns on job stress and its harmful effects on workers’ health.
