Everything in the life circle deserves its place on earth. If we continue using plastic lunch boxes, shopping bags and other unrecyclable plastic products, what would happen? One day they might bury us in an ocean of white rubbish. Then the earth, our common home, would be a dustbin. To prevent this nightmare from coming true, governments need to work closely with each other and back up their verbal commitment by actions.

Vertical Farms By the year 2050, nearly 80%of the earth's population will have resided in urban centers. An estimated 109 hectares of new land will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. So an entirely new approach to farming must be invented, employing cutting edge technologies. The concept of indoor farming is not new. What is new is the urgent need to scale up this technology to accommodate a fast growing number of people. Vertical farming was thus invented. Rice on the seventh floor, wheat on the twelfth, and enough food within an eighteen-story tower to feed a small city of 50,000.Vertical farms must be cheap to construct and safe to operate. If successfully implemented, they will offer the promise of urban renewal, sustainable production of a safe and varied food supply, and the eventual repair of ecosystems that have been sacrificed for horizontal farming.

In some cases, artificial flavorings and colorings are used in addition to, or in replacement of the natural ingredients. This mixture is stirred slowly while cooling to prevent large ice crystals from forming. The result is a smoothly textured ice cream. The meaning of the term ice cream varies from one country to another. In some countries, like the USA, the term ice cream applies only to a specific variety.

The Necktie The necktie or tie is a long piece of cloth worn for decorative purposes around the neck or shoulders, resting under the shirt collar and knotted at the throat. The necktie is one of the few fashion accessories to have survived nearly 400 years of social changes. Neck decorations have been worn since
ancient times to signify title or wealth. Modern decorative neckwear dates back from the 17th century in France. The Industrial Revolution helped spread the style to the masses, as millions of workers migrated from farmlands to factories and the business class was born. By the 1950s, it was said that a man wasn't fully dressed until he had put on his tie. The tie had later come to symbolize individuality as much as conformity. Neckties are available in varied size.

In the 20th century, war became more complex. War games moved into the actual field, with the military conducting live exercises. Since World War Ⅱ, the US has simulated hundreds of aerials and naval assaults. In today’s war games, computer imitations do much of the heavy lifting. As commanders deploy in the field, programs calculate casualty rates. Computers adjust for weather factors and render a score, allowing the games to come as close to war as possible without imposing real violence.
34. The Free Hugs Campaign The Free Hugs Campaign is a social movement involving individuals who offer hugs to strangers in public places. The campaign in its present form was started in 2004 by an Australian man. Initially, people were suspicious of the strange man on the street offering to hug anyone who wanted one. Soon, however, suspicion gave way to enthusiastic acceptance. When authorities tried to stop the campaign, over 10,000 people signed to ensure its continuance. The campaign became famous internationally in 2006 as the result of a music video uploaded into the Internet. The response to the video was astounding. Many people joined this newly created movement, and went out offering free hugs to whoever wanted one.

The hugs are meant to be random acts of kindness, reputedly selfless acts performed by a person for the sole reason of making other feel
35. Effects of Cell phone Cell phones are an unavoidable part of daily life. Even if you do not own one yourself, you are exposed to them all the time whenever you enter the public areas. Most people think of their cell phones as something that they “just could not live without.” Make sure you are informed about potential health hazards associated with cell phone use that the cell phone companies do not want you to know. While studies are not conclusive, scientists are beginning to suspect that cell phone use could contribute to everything from headache to brain cancer. This is because cell phone emits electromagnetic waves and small amounts of radiation. While research done in the 1990’s indicated that the radiation using a cell phone could expose you to is not really enough to do any damage, many experts are now abolishing that opinion. They recommend that, at the very least, children, teens and young adults avoid using cell phones except in emergencies.

They consist of everything from entire spent satellites to explosion fragments, deliberate insertion of small needles, and many other objects. As orbits often overlap, the space junk is a potential collision risk for spacecraft. The vast majority of pieces of spaces of space junk are small particles. Contact with these particles causes erosive damage. The majority of the damage can be eased by adding a thin layer of metal outside of the main spacecraft body. However, certain portions of many satellites cannot be protected in this way, the solar panels and windows for instance. If a collision with larger pieces occurs, many of the resulting fragments from the damaged spacecraft will also be in the 1 kilogram mass range. Consequently, these objects become an additional collision risk. 42. Summer Camp Summer camp is a supervised program for children which is conducted usually during the summer months. It is a regular childhood in the United Stated. Camps can be for all ages. The primary purpose of many camps is educational or for culture development. A summer camp may aloe children to take healthy risks in a safe and nurturing environment. The tradition view of a summer camp as a woody place where kids go hiking and boating and start camp fires is evolving. Now people have greater acceptance of newer summer camps that offer a wide variety of specialized activities. For example, there are camps for magic performing, language learning and even weight loss. Many camps add new programs to counter a trend in decreasing enrollment. Smaller family of sizes, the growth in supplemental educational programs and the popularity of electronic media are the main causes of the decline in attractiveness of summer camps. All of them have kept children inside and
occupied. 43. Illiteracy in Africa ①Illiteracy in Africa is at extremely high levels. / ②21 nations have adult literacy rates below 50% / and overall 4 of every 10 Africans are illiterate. / ③ Achieving higher rates of literacy is a vital part of the effort to eradicate African poverty. / ④But the relationship between the two is complex, / because the effects of poverty are a major obstacle to literacy. / ⑤Given the widespread poverty, / few parents can afford to send their children to school. / ⑥ Raising literacy rates depends on governments making schools and programs for adult education available. / ⑦Some governments are making a real effort to improve literacy. / ⑧However, many government officials are either indifferent or corrupt, / giving education a low priority, or the government efforts are poorly organized and implemented. / ⑨Non-governmental organizations can help, / but they must depend on local governments to step up and become a partner, / rather than an obstacle to progress.

Focusing on the learning process for the individual, experiential learning engages the learner at a more personal level by addressing his or her needs and wants. An example of experiential learning is going to the zoo. The learning happens through observation and interaction with the zoo environment, as opposed to reading about animals from a book. And thus, one makes discoveries and experiments with knowledge firsthand, instead of hearing or reading about others’ experiences. Experiential learning requires no teacher. It relates solely to the meaning-making process of the individual’s direct experience. Knowledge is continuously gained through both personal and environmental experiences. For the adult learner especially, experience becomes a living textbook to which they can refer. However, experiences do not automatically equate learning. So qualities such as self-initiative and self-evaluation are required. 45. Decision Making Human performance in terms of decision making has been the subject of active research from several perspectives. From a psychological perspective, it is necessary to examine individual decisions in the context of a set of needs and preferences an individual has. From an intellectual perspective, the decision making process must be regarded as a continuous process integrated in the interaction with the environment. From a regulating perspective, the analysis of individual decisions is concerned with the logic of decision making and rationality and the stable choice it leads to. Yet, at another level, it might be regarded as a problem-solving activity which is terminated when a
satisfactory solution is found. And therefore decision making is a reasoning or emotional process. It can be based on explicit assumptions or tacit assumptions. Logical decision making is an important part of all science based professions. Specialists apply their knowledge in a given area to making informed decision. 46. Online Consultations Online consultations refer to an exchange between government and citizens using the Internet. It consists in using electronic technologies to ask a group people their opinions on one or more specific topics, allowing for exchanges between participants. Generally speaking, an agency consults a group of people to get their thoughts on an issue when a project or a policy is being developed or implemented. For instance, to identify or access options or to evaluate ongoing activities. This enables the government to draft more citizen-centered policies. As the Internet gains in popularity with the public for voicing opinion, citizen participation in policy making through cyberspace is changing the face of democracy. Through online engagement, the government is enabled to hold interactive dialogues with the public, as it has more direct route to citizen opinion through the Internet. Many countries are integrating online consultations using various methods and for a range of purposes. 47. Lead Time ①Lead time is the period between a customer's order and delivery of the final product. / ②A small order of a pre-existing item may only have a few hours' lead time, / but a larger order of custom-made parts may have a lead time of weeks, months or even longer. / ③It all depends on a number of factors, / from the time it takes to create the machinery to the speed of the delivery system. / ④Lead time may change according to seasons or holidays / or overall demand for the product. / ⑤Manufacturers are always looking for ways / to improve the lead time on their products. / ⑥Lead time can mean the difference / between making the sale and watching a competitor sign the contract. / ⑦If a company can deliver the product weeks ahead of the competition, / it stands a better chance of receiving future orders. / ⑧Because of this, management and labor teams routinely hold meetings / to discuss lead time improvements.

The main types of social networking services are ones containing category places, means to connect with friends and a recommendation system linked to trust. Many networks focus on providing both services and community to individuals with shared interests. 49. Sight ①Sight is very effective at giving exact information over considerable distances. /②If the viewed object is moving, / it can tell us much about the speed and direction of this movement / as well as allowing us to identify it. / ③For all this to happen we need to see it. / ④This means our eyes have to be looking in the correct direction. / ⑤Light waves do not go around objects very well, / so we cannot see an object if it is hidden behind another object. /⑥This does put limits on what sight can achieve. / ⑦Sight is an easy sense to use, / because during the day we are surrounded by light supplied by the sun. /⑧This light bounces off things and brings us information about them./⑨However, when the sun sets on a cloudy night, / the light is mostly gone, / and then vision shall become less useful as a sense.

Aging Problems ①UN has claimed that the number of people on the globe / should as expected reach 9.2 billion in 2050, / which will include elderly persons numbering 1 billion. / One of the surprises is tat/ population growth is most concentrated in the 60 plus age group,/which is expected almost to triple./Whilst many regard the aging of the population as a triumph of a civilized and caring society, /others see it as a major problem facing the community./ The increasing aging population will cause the increase in the dependency ratio./ This means that there will be more people claiming benefits such as state pensions, / and less people working and paying income taxes. /Thus, those in work will have to pay higher taxes. /This could create disincentives to work and for firms to invest,/ therefore there could be a fall in productivity growth. / The shortage of workers could push up wages, causing wage inflation.
