What results in good health and longevity? It’s good genes, good lifestyle and good luck. But since we can’t choose our parents, or know what fate holds in store for us, we must treat lifestyle with tender, loving care. Now, a report “Circulation” proves that a sound lifestyle adds 12 to 14 more years to life. For instance, a woman, aged 50, who follows these lifestyle rules can expect to live to 93 years. This compares to a woman who indulges in an unhealthy lifestyle and dies at 79. In men, the increase in longevity from a healthy lifestyle is from 76 to 88 years. In the general population, the U.S. spends more money on health care than any other country. So why are so many people in North America suffering from ill health? It is quite apparent that the epidemic of obesity, type 2 diabetes and heart attack will continue to be the big killers. At the moment there is little evidence this battle is being won. But a study that followed both staff and students at the University of Liverpool shows it’s not an impossible dream. In its first experiment, female diners were randomly divided to receive either a small or large quiche for lunch. The next day, the same group were all allowed to serve themselves any portion they desired. Researchers discovered the ones who had been served the smaller portion, tended to choose the smaller portion. A second experiment tested male diners and it produced the same result. In the third experiment both sexes were included, but it was done one week later. This time diners were asked to look at various photos of portion size and asked which looked normal. Those who were previously given the smaller portions considered the smaller ones normal.  These studies showed that it is possible to shift people from what they think is a normal portion to what is actually the proper amount to eat. And that the perception of what is normal lasts at least to one week later. Remember, a voyage of a thousand miles begins with the first step. The same philosophy applies to longevity. So, gradually incorporate one thing at a time into your lifestyle. Don’t forget the importance of smaller portions, add more fruits and vegetables, buy a pedometer to check the number of steps taken each day, and to measure your progress, step on the scale every day  
7. According to paragraph 4, what can be deducted from the experiment of the University of Liverpool?

The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Who talks more - men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has the studied the communication style of men and women, says that this is a stereotype. According to Tannen, women are more verbal - talk more - in private situations, where they use conversation as the “glue’ to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these difference even in children. Little girls often play with one ‘best friend’ and their play includes a lot of conversation. Little boys often play games in groups, their play usually involves more doing than talking. In school, girls are often better at verbal skills, while boys are often better at mathematics.
A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversation between children aged 3-6 and their parents. They found evidence that parents talk very differently to their sons than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters, they use more descriptive language and more details. There is also far more talk about emotions, especially with daughters than with sons.

All the different plants and animals in a natural community are in a state of balance. This balance is achieved by the plants and animals interacting (1) _______ each other and with their non-living surroundings. An example of a natural community is a woodland, and a woodland is usually dominated by a particular species of plant, such as the oak tree in an oak wood. The oak tree in this example is therefore called the dominant species but there are also many other types of plants, from brambles, bushes, and small trees to mosses, lichens and algae (2) __________ on tree trunks and rocks. The plants of a community are the producers: they use carbon dioxide, oxygen, nitrogen to build up their tissues using energy in the form of sunlight. The plant tissues form food for the plant-eating animals (herbivores) (3) _______ are in turn eaten by flesh-eating animals (carnivores). Thus, plants produce the basic food supply for all the animals of a community. The animals themselves are the consumers, and are either herbivores or carnivores. Examples of herbivores in a woodland community are rabbits, deer, mice and snails, and insects such as aphids and caterpillars. The herbivores are sometimes eaten by the carnivores. Woodland carnivores are of all sizes, from insects such as beetles and lacewings to animals such as owls, shrews and foxes. Some carnivores feed on herbivores, some feed on the smaller carnivores, (4) _______ some feed on both: a tawny owl will eat beetles and shrews as well as voles and mice. These food relationships between the different members of the community are known as food chains or food (5) ______. All food chains start with plants. The links of the chain are formed by the herbivores that eat the plants and the carnivores that feed on the herbivores. There are more organisms at the base of the food chain than at the top; for example, there are many more green plants than carnivores in a community

Read the following passage and choose the best answer (A, B, C, D):
Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership. “Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources,” he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism." Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world’s 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newpaper, Boley and coauthor Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state. Ecotourists not only provide a boost to the economy in such places, they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection. “The public has become increasing less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public’s interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas

Read the following passage and choose the best answer (A, B, C, D):
Stage and film acting both involve performances in front of an audience. There are fundamental differences between the two. When you act for the stage, you are performing in front of a live audience. That means that your voice and your body movements must be clear even to those seated at the back row. Film acting, on the other hand, requires no voice projection. This is because you are performing in front of the camera. Although a film actor still needs to put the right expression to pull off a role realistically, overdoing movement or being overly expressive actually works against him in film acting because this can be construed as overacting. Controlled and small gestures are the requirements when acting for film. Another difference between stage acting and film acting is the material that is used. Theater involves doing well-known plays time and time again. As such, directors, producers and even avid theater-goers know the plays by heart. Some would even know every line and have developed expectations on how it should be delivered. When a line is not correctly said or the action delivered is not what is expected, an actor can be criticized severely. This is not an issue with film acting because the script is freshly-written. There are basically no expectations on how a role is supposed to be played. Putting the character to life becomes your responsibility and casting directors often choose talents based on their ability to give an authentic and believable performance. The fact that stage acting is done in real time also differentiates it from film acting. The scenes are done in sequence, often building up to a climax. This means that stage actors can’t afford to make mistakes. They have to memorize their lines well or risk forgetting in the middle of the performance. Stage actors must also exhibit quick thinking in case something unexpected happens on stage. Film acting is not done in front of a live audience. Although actors are encouraged to perform the scene perfectly on the first take because of budgetary considerations, a scene can always be redone in case the director is not satisfied with it. When an actor forgets his lines, there is always a script that can be referred back to without causing any damage to the outcome of the movie.

Sophia is a humanoid robot developed by Hong Kong-based company Hanson Robotics. She has been designed to learn and adapt to human behavior and work with humans, and has been interviewed around the world. In October 2017, she became a Saudi Arabian citizen, the first robot to receive citizenship of a country. According to herself, Sophia was activated on April 19, 2015. She is modeled after actress Audrey Hepbum,and is known for her human-like appearance and behavior compared to previous robotic variants. According to manufacturer, David Hanson, Sophia has artificial intelligence, visual data processing and facial recognition. Sophia also imitates human gestures and facial expressions and is able to answer certain questions and to make simple conversations on predefined topics (e.g. on the weather). The robot uses voice recognition technology from Alphabet Inc. (parent company of Google) and is designed to get smarter over time. Sophia’s intelligence software is designed by SingularityNET. The AI program analyses conversations and extracts data that allows her to improve responses in the future. It is conceptually similar to the computer program ELIZA, which was one of the first attempts at simulating a human conversation. Hanson designed Sophia to be a suitable companion for the elderly at nursing homes, or to help crowds at large events or parks. He hopes that she can ultimately interact with other humans sufficiently to gain social skills. Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have been impressive, such as lengthy discussions with Charlie Rose on 60 Minutes. In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk, and watching too many Hollywood movies”. Musk tweeted that Sophia could watch The Godfather and suggested “What’s the worst that could happen?”. On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed. On October 25, at the Future Investment Summit in Riyadh, she was granted Saudi Arabian citizenship, becoming the first robot ever to have a nationality. This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record.
