Facts About Food

Everywhere on earth there are"food specialists"with opposite (or different) opinions on the best kinds of nutrition for various purposes. A lot of people believe that the healthiest diets are high in fiber ,vitamins ,and minerals but low in fat ,cholesterol ,sugar,and salt. Some nutritionists say the perfect eating plan contains mostly carbohydrates without much protein. In contrast , other scientists say people need high-protein meals with meat, chicken , fish , or milk products and only small amounts of grains , potatoes , breads , rice , and noodles. One famous diet plan allows only certain foods at certain times-protein with protein, carbohydrates with carbohydrates , fruits alone , and so on. Some eaters stay away from all meat and maybe even fish and milk products. They get their protein from plants , mostly beans. Others want only high-fiber food. These people may not eat white bread or white rice or even cooked vegetables. So what is the best way to eat and be healthy? The discussion of food facts will go on far into the future.

The necessary substances and elements for human life and health are water, protein, carbohydrates ,fats , vitamins, and minerals. Most kinds of food contain some or all of the required nutrients , but these substances have different effects on people. Various ingredients and dishes affect the mind in different ways. and some kinds of nourishment have better effects on the brain than others. For instance. can broccoli increase brain power? Maybe so. Low levels of some of the B vitamins can cause a decrease in memory and thinking ability , nutritionists say, but dark green vegetables , like broccoli , contain a lot of these nutrients. Another example of a"memory helper"is lecithin-a substance from soybeans , also found in high-fiber foods like nuts and whole grains. High-protein foods influence the mind in more helpful ways than dishes high in sugar and carbohydrates. And the caffeine in coffee or tea may help thinking. Of course , its effects don't last long.

In many places outside big cities , food with more than four legs is part of good, healthy home cooking. Fried or grilled ants are a tasty but expensive snack in Colombia , South America. In various parts of Mexico , over 300 types of insects serveas food. In southern Africa. many people like to eat at least one kind of caterpillar or worm. They enjoy it fried , dried , or cooked in tomato sauce. In Thailand , cooks create a spicy hot pepper sauce with water bugs. In Vietnam , grasshoppers filled with peanuts are a special dish. And in some regions of China,bugs are not only a part of meals but an important ingredient in medicine too. Most kinds of insects have high nutritional value. They contain a l0t of protein , vitamins , and minerals. Many people like their taste. They are everywhere on the planet. They add to the variety of people' s diets. For several reasons , insects are an important kind of food in the global diet , and they may become a more common ingredient in the future.

The growing similarities in diet and eating habits around the world are influencing people of various cultures in different ways. For example, Western foods are damaging health in the industrialized island country of Japan. Instead of small meals of seafood , rice , and vegetables ,the typical Japanese diet ow includes large amounts of meat ,dairy products. And desserts like tiramisu , a rich Italian dish full of chocolate , cheese , and sugar. According to Japanese health researchers , such changes in eating habits are related to a great increase in health problems such as heart disease , strokes , cancer , and diabetes. On the other hand , the changing global diet is having the opposite effect on the people in the Czech Republic. The government of this European nation no longer supports meat and dairy products financially , so the cost of these foods is going up. In contrast , fresh fruits and vegetables are becoming more widely available from private markets and stands. Cooks are even serving salads to schoolchildren ,and families are eating healthier home-cooked meals. For these reasons ,fewer Czech men are having heart attacks , the women are l0sing a l0t of weight , and most people are living healthier lives.

The future of personal satellite technology is here—are we ready for it?

A)Satellites used to be the exclusive playthings of rich governments and wealthy corporations. But increasingly, as space becomes more democratized, they are coming within reach of ordinary people. Just like drones (无人机)before them, miniature satellites are beginning to fundamentally transform. our conceptions of who gets to do what up above our heads.

B)As a recent report from the National Academy of Sciences highlights, these satellites hold tremendous potential for making satellite-based science more accessible than ever before. However, as the cost of getting your own satellite in orbit drops sharply, the risks of irresponsible use grow. The question here is no longer "Can we?" but "Should we?" What are the potential downsides of having a slice of space densely populated by equipment built by people not traditionally labeled as "professionals" ? And what would the responsible and beneficial development and use of this technology actually look like? Some of the answers may come from a nonprofit organization that has been building and launching amateur satellites for nearly 50 years.

C)Having your personal satellite launched into orbit might sound like an idea straight out of science fiction. But over the past few decades a unique class of satellites has been created that fits the bill: CubeSats. The "Cube" here simply refers to the satellite's shape. The most common CubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. These mini-satellites can fit in a launch vehicle's formerly "wasted space. " Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone.

D)Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable operators to study Earth from space, as well as space around Earth. They're primarily designed for Low Earth Orbit (LEO)—an easily accessible region of space from around 200 to 800 miles above Earth, where human-tended missions like the Hubble Space Telescope and the International Space Station (ISS) hang out. But they can attain more distant orbits; NASA plans for most of its future Earth-escaping payloads (to the moon and Mars especially) to carry CubeSats.

E)Because they're so small and light, it costs much less to get a CubSat into Earth's orbit than a traditional communications or GPS satellite. For instance,a research group here at Arizona State University recently claimed their developmental small CubeSats could cost as little as $3,000 to put in orbit. This decrease in cost allows researchers, hobbyists and even elementary school groups to put simple instruments into LEO or even having them deployed from the ISS.

F)The first CubeSat was created in the early 2000s,as a way of enabling Stanford graduate students to design, build, test and operate a spacecraft with similar capabilities to the USSR's Sputnik (前苏联的人造卫星).Since then, NASA, the National Reconnaissance Office and even Boeing have all launched and operated CubeSats. There are more than 130 currently in operation. The NASA Educational Launch of Nano Satellite program, which offers free launches for educational groups and science missions, is now open to U. S. nonprofit corporations as well. Clearly, satellites are not just for rocket scientists anymore.

G)The National Academy of Sciences report emphasizes CubeSats' importance in scientific discovery and the training of future space scientists and engineers. Yet it also acknowledges that widespread deployment of LEO CubeSats isn't risk-free. The greatest concern the authors raise is space debris—pieces of "junk" that orbit the earth, with the potential to cause serious damage if they collide with operational units, including the ISS.

H)Currently, there aren't many CubeSats and they're tracked closely. Yet as LEO opens up to more amateur satellites, they may pose an increasing threat. As the report authors point out, even near-misses might lead to the "creation of a burdensome regulatory framework and affect the future disposition of science CubeSats."

I)CubeSat researchers suggest that now's the time to ponder unexpected and unintended possible consequences of more people than ever having access to their own small slice of space. In an era when you can simply buy a CubeSat kit off the shelf, how can we trust the satellites over our heads were developed with good intentions by people who knew what they were doing? Some "expert amateurs" in the satellite game could provide some inspiration for how to proceed responsibly.

J)In 1969.the Radio Amateur Satellite Corporation (AMSAT) was created in order to foster ham radio enthusiasts' (业余无线电爱好者)participation in space research and communication. It continued the efforts, begun in 1961, by Project OSCAR—a U. S. -based group that built and launched the very first nongovernmental satellite just four years after Sputnik. As an organization of volunteers, AMSAT was putting "amateur" satellites in orbit decades before the current CubeSat craze. And over time, its members have learned a thing or two about responsibility. Here, open-source development has been a central principle. Within the organization, AMSAT has a philosophy of open sourcing everything—making technical data on all aspects of their satellites fully available to everyone in the organization, and when possible, the public. According to a member of the team responsible for FOX 1-A, AMSAT's first CubeSat, this means that there's no way to sneak something like explosives or an energy emitter into an amateur satellite when everyone has access to the designs and implementation.

K)However, they're more cautious about sharing information with nonmembers, as the organization guards against others developing the ability to hijack and take control of their satellites. This form. of "self-governance" is possible within long-standing amateur organizations that, over time, are able to build a sense of responsibility to community members,as well as society in general. But what happens when new players emerge, who don't have deep roots within the existing culture?

L)Hobbyists and students are gaining access to technologies without being part of a long-standing amateur establishment. They're still constrained by fimders, launch providers and a series of regulations—all of which rein in what CubeSat developers can and cannot do. But there's a danger they're ill-equipped to think through potential unintended consequences. What these unintended consequences might be is admittedly far from clear. Yet we know innovators can be remarkably creative with taking technologies in unexpected directions. Think of something as seemingly benign as the cellphone—we have microfinance and text-based social networking at one end of the spectrum, and improvised (临时制作的)explosive devices at the other.

M)This is where a culture of social responsibility around CubeSats becomes important-not simply to ensure that physical risks are minimized, but to engage with a much larger community in anticipating and managing less obvious consequences of the technology. This is not an easy task. Yet the evidence from AMSAT and other areas of technology development suggests that responsible amateur communities can and do emerge around novel technologies. The challenge here, of course, is ensuring that what an amateur community considers to be responsible, actually is. Here's where there needs to be a much wider public conversation that extends beyond government agencies and scientific communities to include students, hobbyists，and anyone who may potentially stand to be affected by the use of CubeSat technology.

36. Given the easier accessibility to space, it is time to think about how to prevent misuse of satellites.

37. A group of mini-satellites can work together to accomplish more complex tasks.

38. The greater accessibility of mini-satellites increases the risks of their irresponsible use.

39. Even school pupils can have their CubeSats put in orbit owing to the lowered launching cost.

40. is careful about sharing information with outsiders to prevent hijacking of their satellites.

41. NASA offers to launch CubeSats free of charge for educational and research purposes.

42. Even with constraints, it is possible for some creative developers to take the CubeSat technology in directions that result in harmful outcomes.

43. While making significant contributions to space science, CubeSats may pose hazards to other space vehicles.

44. Mini-satellites enable operators to study Earth from LEO and space around it.

45. AMSAT operates on the principle of having all its technical data accessible to its members, preventing the abuse of amateur satellites.

Humans live in a world where many other living things compete for food and places to breed. The pathogenic organisms, ,or pathogens, are often broadly called germs, which cause many diseases to be able to invade the human body and use its cells and flu- ids for their own needs. (46)

Pathogenic organisms can enter the body in various ways. Some —such as those that cause the common cold, pneumonia, and tuberculosis—are breathed in. (47) Still others—such as those that cause bacillary dysentery, cholera, and typhoid fever— get in the body through contaminated food, water, or utensils.

Insects can spread disease by acting as vectors, or carriers. . (48) Germs may also enter the body through the bite of a mosquito, louse, or other insect vector. Kinds of disease

Infectious, or communicable, diseases are those that can be passed between persons such as by means of airborne droplets from a cough or sneeze. Tiny organisms such as bacteria and fungi can produce infectious diseases. So can viruses. So can tiny worms. Whatever the causative agent might be, it survives in the person it infects and is passed on to another. Or, its eggs are passed on. . (49)

The asymptomatic carrier can then pass the disease on to someone else without even knowing he has it.

Noninfectious, or noncommunicable, diseases are caused by malfunctions of the body. These include organ or tissue degeneration, erratic cell growth, and faulty blood formation and flow. Also included are disturbances of the stomach and intestine, the endocrine system, and the urinary and reproductive systems. Some diseases can be caused by diet deficiencies, lapses in the body&39;s defense system, or a poorly operating nervous system.

. (50) These ailments include drug addiction, obesity, malnutrition, and pollution-caused health problems.

??A. A disease is a condition that impairs the proper function of the body.B. Ordinarily, the body&39;s defense system can ward off these invaders.C. Disability and illnesses can also be provoked by psychological and social factors.D. Sometimes, a disease-producing organism gets into a person who shows no symptoms of the disease.E.
