John O'Keefe, in full John Michael O'Keefe (bom Navember 18, 1939, New York City New York, U.S), Brtish-American neuroscientist who contibuted to the discovery of place cells in the hippocampus of the brain and elucidated their role in cognitive (spatial) mapping. O'Keefe's investigations of impairments in the cognitive mapping abiltes of rats had important implications for the understanding of Alzheimer disease and other human neurological conditions in which affected persons fail to recognize their surroundings. For his contributions to the understanding of neural processes involved in the mental representation of spatial environments, O'Keefe shared the 2014 Nobel Prize for Physiology or Medicine with Norwegian neuroscientists May-Britt Moser and Edvard I. Moser. O'Keefe grew up in New York City, the son of Irish immigrants. He studied aeronautical engineering at New York University before enroling in 1960 at the City College of New York (CCNY) to study philosophy of the mind. After earning a bachelor's degree from CCNY in 1983, he wento McGil University in Montreal, where he cartied out graduate studies in the school's psychology department. At MeGil O'Keofe worked in the laboratory of Canadian psychologist Ronald Meizack, researching the sensory properties of the amygdala (a part of the brain involved in the fight-or-fight response) and developing tools and methods for his investigations. He completed a doctorate degree in physiological psychology in 1967, that same year joining University College London (UCL) as a postdoctoral research fellow. He remained at UCL for the duration of his career, eventually serving as a professor of cognitive neuroscience. Within a few years at UCL, O'Keefe shifted his research from the amygdala to the hippocampus, attempting to understand its role in animal behavior. Using techniques to record the activity of individual neurons in the rat hippocampus, he was able to observe the responses of single cells and correlate their activity to specific behaviors. Of particular interest to O'Keefe were rats that had sustained damage to the hippocampus, which produced significant changes in behavior, such as reduced performance on spatial tasks and hyperactivily in new environments. After many experiments, O'Keefe discovered that cell activity in certain areas of the hippocampus was a function of place, with activity related specifcally to where an animal was in its environment. In 1978, O'Keefe and colleague Lynn Nadel published The Hippocampus as a Cognitive Map, describing in detail a theory that placed the cognitive map—the existence of which was first proposed in 1948 by American psychologist Edward C. Tolman — specifcaly in the hippocampus. The neural system elucidated by O'Keefe and colleagues was described populariy as an “inner GPS." O'Keefe's research was crucial in that it provided the first experimental evidence for such a system and offered insight into the ability of animals, including humans, to orient themselves within an environment, to navigate from one place to another, and to remember spatial information. The loss ofthose abilties in human is a hallmark of neurological disease, particulaly Alzheimer disease, for which O'Keefes findings opened up new avenues of research. His work also fueled progress in scientists' understanding of human cognition, especially aspects of memory. (http://www.britannica. com/biography/John-OKeefe) Paragraph 4 implies that .... A. Scientist won't understand memory's aspects of the human cognition. B. The evidence of neural system experiment is un-trustable. C. Lynn Nadel is a co-writer of The Hippocampus as a Cognitive Map. D. The signs of an Alzheimer disease are loss the ability to orient themselves, to navigate from one place to another, and to remember spatial information. E. O'Keefe's theory is about the cognitive map.

Maintaining a healthy lifestyle requires persistence and dedication, but not without reward. Regular exercise, not smoking, limited alcohol consumption, adequate sleep, and a balanced diet are all aspects of a healthy lifestyle. In general, a healthy life style benefits people in various ways. According to study by the Centers of Disease Control and Prevention, practicing a healthy lifestyle makes individuals' risk of premature death 66 percent less likely from cancer, 65 percent less likely from cardiovascular disease, and 57 percent less likely from other causes. The four healthy lifestyle factors studied include limited alcohol consumption, avoiding tobacco, improved nutrition, and regular physics activity. Apart from consuming more whole and fresh foods, every individual should avoid foods with large amounts of sodium, trans fair, saturated fats, added sugars, and processed grains. In addition, it is no secret that a healthy lifestyle can help us shed pounds and look more youthful, but it goes beyond weight loss. For example, staying hydrated and getting adequate sleep can reduce the appearance of under-eye bags. Limiting alcohol intake reduces its aging effects on our skin and eyes, as does avoiding tobacco. Proper nutrition from a balanced diet also supplies our body with the nutrient it needs for healthy and lustrous hair, bright eyes, tight skin, and an overall glow. According to MayoClinic.com, physical activity triggers the release of brain chemicals that can make us feel relaxed and happier. This emotional boost can help our outlook about our appearance and improve self-confidence. Besides, the mood enhancing chemicals released by physical activity can help us face the troubles of a stressful day with a calmer mindset. Furthermore, exercising regularly makes body stronger and improves its endurance. Physical activity also conditions our cardiovascular system, which helps keep our muscles energized by del ivering oxygen more efficiently. As a result, we will have more energy to do everyday tasks. A balanced diet, limited alcohol consumption, and proper hydration also aid in increasing energy levels, according to Harvard Health Publications, limiting alcohol consumption also promotes a better mood. Adapted from http://healthyeating.sfgate.com Based on the passage, what should we do if we want to have a better mood? We should (A) do regular physical activities. (B) minimize the risk of illnesses. (C) help other to solve daily-l ife problems. (D) reduce the aging effects on our skin and eyes. (E) keep our muscles energized by doing sports.

Falcon, any of nearly 60 species of hawks of the family Falconidae (order Falconiformes) , diurnal birds of prey characterized by long, pointed wings and swift, powerful flight. The name is applied in a restricted sense, as true falcons, to the genus Falco, which numbers more than 35 species. Falcons occur virtually worldwide. They range in size from about 15 cm (6 inches) long in the falconets (Microhierax) to about 60 cm (24 inches) in the gyrfalcon, an Arctic species. Falcons have tapered wings that al low the falcon to change incredible flying abilities. Falcons have tapered wings that allow the falcon to change direction extremely quickly especially when compared to other birds. Falcon have been recorded diving at speeds of up to 200mph, meaning they are the fastest creatures on the planet! Falcons are birds of prey and are therefore known for their incredible hunting skills and being a ruthless, dominant predator within their environment. Falcons hunt their prey from the skies above and swoop down through the air to catch it once they have spotted a meal with their incredible eyesight. Falcons hunt all kinds of small animals ike mice, frogs, fishand falcons will even catch small birds in the air. Falcons have adapted in many ways to maximize their chances of survival in the skies. The falcon has tapered wings that al low the falcon to be more agile; incredibly acute eyesight which anables the falcon to spot prey on the ground far below; an aerodynamic body shape means that the falcon glides through the air more easily and a sharp pointed beak helps the falcon to grab and eat it's prey more effectively. Peregrine falcons in the United States, however, were listed as an endangered species after their number dropped dangerously low between the 1950s and the 1970s. Certain pesticides used by farmers---including DDT -harmed the peregrines by causing their eggshells to be dangerously thin-so fragile that they broke when the parents tried to incubate them. Laws were anacted to ban DDT and, fortunately the ban, along with other conservation efforts, led to the recovery of the species and for the sake of the ecosystem too. In fact, scientists think there now may be more peregrines in some parts of their range than there ever used to be. Adapted from https://www.britannica.com/animal/falcon-bird What most likely motivates the author in writing the passage? (A) The government have given abundant attention to other species but not to falcons. (B) There is a worry that falcons will not ·be conserved despite their unlimited number. (C) There are still unresolved problems about the laws of the use of pesticides in the society. (D) The information about this species is limited and people's awaress to their extinction is still low. (E) There are a few misconceptions of society about the use of pesticide that might endangers species.
