unit 5 traveling abroad reading课时作业阅读理解awith around 100 students scheduled to be in that 9 am monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pyjamas(睡衣). obviously, students are terrible at adjusting their sleep cycles to their daily schedule. all human beings possess a body clock. along with other alerting(警报)systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. this typical sleep pattern is usually referred to as the “night owl” schedule of sleep. this is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. such a person has great difficulty in waking up in the mornings. research suggests that night owls feel most alert and function best in the evenings and at night. research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds”the other 70 percent are in the middle. although this is clearly not true for all students, for the ones who are true night owls this gives them an excellent excuse for missing their lectures which unfortunately fall before midday. 1. what does the author stress in paragraph 1?a. many students are absent from class. b. students are very tired on monday mornings. c. students do not adjust their sleep patterns well. d. students are not well prepared for class on mondays. 2. which of the following is true according to paragraph 2?a. most students prefer to get up late in the morning. b. students dont sleep well because of alerting systems. c. ones body clock governs the sleep/wake cycle independently. d. adolescents delayed sleep/wake cycle isnt the preferred pattern. 3. which of the following is closest in meaning to the underlined word “classified”?a. criticised. b. grouped. c. organised. d. named. 4. what does the text mainly talk about?a. functions of the body clock. b. the “night owl” phenomenon. c. human beings sleep behaviour. d. the school schedule of “early birds”. 答案1. c2. d3. b4. bbthis year arrives amid a few interesting trends. more americans are interested in local and sustainable food: urban farming, chicken-raising. and more americans are hunting, spending increasing time and money on that pursuit. viewed from the right angle, though, both these trends could have a place at the holiday table. what would happen if more americans made thursdays (thanksgiving day) meal out of wild turkeys? what if more people enjoyed a wild christmas goose, or wild pig ham? if more did, the result might be better for the environment, for our healthand perhaps for our souls as well. americans growing interest in local food is evident everywhere. according to the us department of agriculture, the number of farmers markets rises from 1, 755 in 1994 to 8, 144 this year. cities from ann arbor, michigan, to gainesville florida, have eased restrictions on backyard chickens. some “locavores” are content to get community-supported agricultural produce delivered, and buy grass-fed beef. but for a growing number, hunting is the next step. the meat is local and avoids the ethical complications of factory farms. hunting has definitely enjoyed a resurgence. census statistics show that the percentage of americans who huntwhich had been falling for decadesis back up at a 20-year high. hank shaw, author of the new wild bird cookbook duck, duck, goose, and owner of the james beard award-winning website hunter angler gardener cook, calls it the omnivores dilemma effect. after reading michael pollans best-selling book on where food comes from, many people join a community-supported agriculture group, but some get a hunting license, too. “i cant tell you how many people i talk to who view hunting as a part of a larger, personal goal of sustainable eating, ” shaw says. of course, characterizing hunting this way blurs many lines. to some, shooting animals cannot possibly be an environmentally friendly activity. the existence of “hipster hunters” is also limited by cultural attitudes toward guns. its almost impossible to legally own a hunting weapon in brooklyn. but hunting wild animals requires the preservation of wild landcertainly an environmental plusand if youre going to eat meat, hunting has a lot going for it that industrial farms do not. add to this the fact that some game populations have grown unnaturally large due to the lack of predators(掠食动物). the east coast is filled with white-tailed deer. geese take up residence on golf courses, and wild pigs wander through the woods. in his 2012 book nature wars journalist jim sterba argued that more humans live in closer contact with wild animals than at my point in history. hunting can keep a check on that. hunting can keep a check on our appetites too. susan cameron devitt, a biologist who recently moved from florida to texas, notes that one of the things you learn quickly from hunting is how much labor goes into producing a meal. “if you buy meat at the grocery store, you can eat three servings a day, but if you imagine trying to keep that up with hunting, it just wouldnt be possible, ” she says. which brings us back to holiday tables? in the original version of thanksgiving and christmas, these were special meals, based around dishes you wouldnt eat frequently. these days, you can buy turkey whenever. a wild turkey, caught and then cooked, is a different matter. a speckle-belly goose elevates the christmas dinner in a way a regular supermarket ham does not. when you know where your food comes from, and when youve labored to bring it to your table, you more naturally feel grateful for the amazing abundance of this planet. “theres no better way to engage with nature than to seek dinner within it, ”says shaw. 5. what can we learn about the trends?a. few people regard hunting as a part of a personal goal of sustainable eating. b. hunting in the usa is consistent with the cultural attitude to guns. c. the media play a part in promoting the popularity of hunting. d. hunting is likely to replace industrial farms. 6. the underlined phrase “game populations” in paragraph 8 refers to. a. the number of huntersb. the number of wild animals and birdsc. animals and birds caught through huntingd. campaigns to ban the hunting of wild animals and birds7. the underlined part in paragraph 9 implies. a. some hunters do not have the desire to eat meat from industrial farmsb. hunting provides hunters with three servings a dayc. some hunters do not have a healthy appetited. hunting helps hunters control their appetites8. what can we infer from the last but one paragraph?a. in the past, people ate turkeys only on thanksgiving day. b. supermarket turkeys will not be accepted by people any more. c. wild turkeys are more delicious than those bought from grocery stores. d. wild turkeys help bring back the festive atmosphere of thanksgiving day. 9. according to the last paragraph, hunting is beneficial for. a. our mental healthb. our physical fitnessc. the environmentd. farmers markets答案5. c6. b7. d8. d9. acto learn to think is to question. those who dont question never truly think for themselves. these are simple rules that have governed the advancement of science and human thought since the beginning of time. advancements are made when thinkers question theories and introduce new ones. unfortunately, it is often the great and respected thinkers who end up slowing the progress of human thought. aristotle was a brilliant philosopher whose theories explained much of the natural world, often incorrectly. he was so esteemed by the scientific community that even 1, 200 years after his death, scientists were still trying to build upon his mistakes rather than correct them!brilliant minds can intimidate up-and-coming thinkers who are not confident of their abilities. they often believe they are inferior to the minds of giants such as aristotle, leading many to accept current paradigms instead of questioning them. i, like many thinkers of the past, once believed in my mental inferiority. i was certain that my parents, my teachersadults in generalwere always right. they were like a textbook to me; i didnt question what was written on those pages. i respected them, and accepted whatever they told me. but that attitude soon changed. my minds independence was first stimulated in the classroom. a stem, 65-year-old elementary-school science teacher once told me that light is a type of wave. i confidently went through years of school believing that light is a wave. one day, however, i heard a german exchange student mentioned that light could be made up of particles. as the others laughed at his statement, i started to question my beliefs. maybe the teachers and textbooks hadnt given me the whole story. i went to the library, did some research and learned of the light-as-a-wave versus light-as-a-particle debate. i read about einsteins discovery of the dual nature of light and learned the facts of a paradox (悖论)that puzzles the worlds greatest thinkers to this day. light behaves as both a particle and a wave;it is both at once. i realized i had gone through life accepting only half of the story as the whole truth. each new year brought more new facts, and i formulated even more questions. i found myself in the library after school, trying to find my own answers to gain a more complete understanding of what i thought i already knew. i discovered that my parents and teachers were incredible tools in my quest for knowledge, but they were never the final word. even textbooks can be challenged, so i learned to question my sources;i learned to be a thinker. i once believed that everything i learned at home and at school was certain, but i have now discovered to re-examine when necessary. questions are said to be the path to knowledge and truth, and i plan to continue questioning. how many things do we know for sure today that we will question in the future? at this moment, i know that our sun will burn for another five billion years, and i know nothing can escape the gravity of a black hole. this knowledge, however, may change in the next 20 yearsmaybe even in the next two. the one thing we can control now is our openness to discovery. questions are the tools of open minds, and open minds are the key to intellectual advancement. 10. in the first paragraph, aristotle is taken as an example to show that . a. he is the greatest and respected philosopher of all timeb. huge influence of great thinkers may block human thought
