unit 1 living well reading课时作业第一节 阅读理解 阅读下列短文，从每题所给的四个选项中（a、b、c、d）中选出最佳选项，并在答题卡上将该项涂黑。 during the family travel ride, a chorus of “im bored” often echoes up from the back seat. luckily for your sanity, you can leave boredom at home by using this list of fun-filled travel games!license plate fun have the little ones see who can find all of the letters in alphabetical order on the license plates that go by. or, give them a list of all 50 states and see how many of them they can find. for a shorter game, have them try to make phrases out of the license plates they see. for example, “bysb 7845” could be “big yellow school bus.” map your journey showing your kids where you are on a map will help the miles fly by, and its a great opportunity to teach them a little geography. if you bring a road map for each child, they can trace your trip in pen or crayon and draw landmarks on the map themselves. when they ask you how far away you are from the next stop, show them how to determine distance using the legend. counting gamesroad trips provide lots of opportunities to practice counting. assign each child a side of the car and see who can count the most cows, horses, billboards, or sheep. if you have one child, you can compete or see how fast your child can make it to 100 items. try switching items every once in a while to ward off boredom. breathless when you go through the tunnel, see which passengers can hold their breath all the way until the end. another classic variation is holding your breath whenever you pass a cemetery. some families include wish-making in this game: successfully hold your breath until the end of the landmark, and your wish will come true. the frankie game in this game, the word “frankie”, as in our lovable mascot, is substituted for a verb. to play, one person picks a secret verb like “swim”. then everyone else asks questions using “frankie” in place of the verb. “can you frankie in the ocean?” “can you frankie in the house?” the person who correctly guesses the secret verb gets to choose the next one. 1. which game can help kids learn about geography?a. the frankie game b. map your journey c. license plate fun d. counting games 2. what can you do if your child gets bored in counting games?a. put the child on one side of the car b. compete with your child c. change items occasionally d. try different ways regularly 3. what do the games mentioned have in common?a. they are full of fun b. they develop kids interest. c. they help parents control their kids d. they need to be played in groups bthe highest beef prices in almost three decades have arrived just before the start of the hot season, causing a great shock to both consumers and restaurant ownersand relief isnt likely anytime soon. a decreasing number of cattle and growing export demand from countries such as china almost a quarter from january and the highest price since 1987. everything thats produced is being consumed, said kevin good, an analyst at cattlefax, a coolorado-based information group. prices will likely stay high for a couple of years as cattle producers start to rebuild their cattle among big questions about whether the southwest and parts of the midwest will see enough rain to water the grass. “i quit buying steaks a while ago when the price went up,” said 59-year-old len markham, who works at texas tech. she says she limits red meat purchases to hamburger, choosing chicken, pork and fish instead. restaurant owners, too, must deal with the high prices. mark hutchens, owner of the 50 yard line steakhouse in lubbock, raised his menu prices for beef items by about 5 percent in november. since then, the owner of the small eating house has tried to make cuts elsewhere to avoid passing it on to customers.” it really puts more pressure on the small guys,” he said of non-chain restaurants. “i just think you have to stay competitive and keep your costs low.”“white-tablecloth restaurants have adjusted the size of their steaks, making them thinner”, says jim robb, director of the colorado-based livestock marketing information center. “and fast-food restaurants are cutting costs by reducing the number of menu items and are offering other meat options, including turkey burgers, robb said. chain restaurants also try to buy beef as much as they can, which essentially gives them a discount”, iowa state university assistant economics professor lee schulz said. the high prices are welcome news for at least one group: ranchers (大农场经营者)，especially those in texas who for years have struggled amid drought and high feed prices. but even as ranchers breathe a sigh of relief, some worry lasting high prices will cause consumers to permanently change their buying habits-switching to chicken or pork. pete bonds, 62-year-old texas rancher and president of the texas rancher and president of the texas and southwestern cattle raisers association, said thats a big concern. “but such fears may be unfounded, robb said. “three years ago, economists thought consumers would start finding substitutions for beef as the drought spread. were surprised we havent seen more of that,” he said. south dakota rancher chuck oconnor thinks that consumers wont abandon beef for good. “im sure some are maybe going to cut back some, but to say that people arent going to buy it anymore. i dont think thats going to happen,” he said, adding, “i hope not.” 4. the price of beef has increased because_. a. there is a growing demand of fresh beef among americans. b. cattle producers have succeeded in raising a new type of cattle. c. ranchers have found ways to deal with high feed prices. d. there is a lack of rain and the export of beef is increasing 5. which method is not used by restaurant owners of deal with the high beef prices?a. they have made the steaks smaller than beforeb. they have increased the prices of beef-related dishes c. they have made hamburgers with may others kinds of meat d. they have sought discount by purchasing large amounts of beef 6. jim robb gives an example in the sixth paragraph in order to _. a. tell people that it is a tough job to look for substitutions for beef b. explain that customers wont change their buying habits completely c. show his fear that chicken or pork may be an alternative to beef d. indicate that ranchers may be least affected by the high beef prices cyour new years plan to move more is one of the toughest to stick to, and a group of scientists working with obsess（过度肥胖的）mice think theyre starting to understand why. rather than our sedentary(久坐的) lives causing weight gain, says alexxai kraviz, the national institutes of health neuroscientist who led the study, changes in brain chemistry after we start gaining weight affect our capacity to move. “obese mice can move just fine,” says kravitz, who published the work with his team in cell metabolism “they just dont.” what kravitzs team found is that the activity of a particular dopamine(多巴胺) receptor linked to movement goes down as mice gain weight on a high-fat diet. so the mice slow down and they move less. and when the researchers restored the activity of that dopamine receptordr2the mice started moving more, even though they were still obese. the team also saw that lean mice missing the dr2 receptor acted like obese mice. this is the target, says kravitzrestoring that dopamine receptor function. “maybe 20 or 30 years down the road, we could do that in people,” he says. and there is one more thing: the scientists fed normal mice and the mice lacking dr2 the same high-fat diet. both sets of mice gained weight at the same rate. kravitz says this is important because mice lacking dr2 move less from the get-go, whereas a normal mouse takes a little time to start seeing that dopamine receptor-related loss of exercise. the ability to exercise seems to be disconnected from weight gain, he says. “exercise is a healthy things to do, but its impact on weight loss has been exaggerated,” he says. “we have to be realistic about the size of the effect of exercise on weight, as opposed to health benefits.”still, before you abandon your new years exercise plan, keep in mind that this study was done using a high-fat diet, and not the normal calorie restriction that people maintain when they diet. thats a big drawback to the work, says vicki vieira-potter, a university of missouri physiologist not involved in the study. “they feed the mice with high-fat diet, it damages the receptor, and that decreases activity. those who plan to lose weight should remember a high-fat diet is a mice way to cause obesity in the lab, but its not the same as the normal situation of obesity,” she says. she also says that a lot of the weight gain in the mice came after they stopped moving around, which indicates that the loss of movement did impact obesity. 7. alexxai kravitz is likely to agree that_.a. high-fat food lead to the lack of dr2 b. less movement results from weight gain c. weight gain leads to the inactivity of dr2 d. the lack of dr2 results in less movement 8. what can we infer from the research mentioned in the passage?a. high-fat diet is bound to cause obesity b. high-fat diet has little influence on the rate of weight gain c. the research team aim to deal with human obesity d. obese mices ability to move is affected by the inactivity of dr29. the underlined word “exaggerated” in paragraph 7 can be replaced by “_”a. underestimated b. excluded c. overlooked d. overemphasized 10. according to vicki vicki-viera-potter, _. a. alexxai kravitzs team misread the results of the research b. the total loss of movement can do harm to the function of dr2 c. besides diet, other factors behind obesity shouldnt be ignored in daily life. d. obesity is mainly caused by high-fat diet people take. dwhen charles lee handed me the small red notebook in 1974, he changed my life. “while you are traveling, you should keep note of things you see and do,” he explained. i was 20 years old, a junior in college, spending a term at the university of london. charles was a retired traveling salesman. i was staying with him in his cottage in kendal, located in the lake district of northern england. it was a one-week homestay the university arranged for us before classes began. i took his advice. i wrote in the notebook every day during the homestay. back in london, i recorded weekend trips to wales, yorkshire, france, and spain. i commented on my classes, professors, and classmates. i contrasted my life at a small college in the us with my wandering through the streets of london, my introduction to life in a big city, and my initial travels outside the us. i tracked ideas i had about my life and my future. when i wrote in the notebook, i struggled with a sense of my audience and purpose. who would read this? were these writing just for me, or did i want others to read them? was i recording events and ideas just as a prompt(提示) to memory, or was there some larger purpose for this daily exercise?i knew i was recording events, thoughts, words that were important to my life. i imagined a future me sitting down to read the pages. i wondered what it would feel like to read those words later. i wondered where i would be and what my life would be like. i filled the notebook charles gave me. i bought a new one and filled it. then another and another. i continued writing in notebooks for four decades. by that time, they filled two boxes in my garage. i had reread some of the journals. specific volumes had provided me with the background i needed for dozens of articles for magazines. but i had never read them all. recently, i decided to bring my collection of notebooks into my office and replay my life. as i opened the first box, i suddenly became nervous: would i like the former me described on those pages? there was a risk in opening that first notebook. i did it anyway. charles had been right. i remembered the big events and the central happenings, but on each page were many details i hadnt retained. the pages revealed highlights from college classes and stories about roommates and friends. i read anxious comments id written as id launched my teaching career, learned to write lesson plans, assigned grades for student work, and solved discipline problems. i reflected on my coming marriage, then the wedding, and eventually the proud moments when i held each of my three girls as a father. i recounted more trips returning to europe, teaching in south america, going on safari(游猎) in africa, and exploring greenland. i relived memories of trail hit, rivers crossed, and mountains climbed. the writings in those journals framed my life. i hadnt written every day. i often skipped a few days or even weeks, but i always picked up the writing when it felt important. journals went with me when i traveled, and i often wrote in them at school when my own students were writing. it took several long evenings to read through the notebooks, taking me on tour spanning(持续) 42years. as i read i could recall sitting on a bench in trafalar square in london or in our apartment in peru to write to the future me. it was then that i realized: i am now the person i was writing to throughout those years. 11. what can we learn about charles lee?a. he was an englishman the author came across b. he

recognizing and absorbing phrases or sentences on a page all at once, rather than identifying individual words. its a surprisingly easy technique to learn, which is based on a few key techniques that anyone can pick up: stop saying the words in your head. subvocalization(默读) is the habit most of us have where we “hear” words in our minds as we read them. _16_ all you need to do is to stop the speech mechanism (机制) in your brain, which means chewing gun, humming, or even eating while youve reading. _17_ this can teach you to stop reading with your mouth. _18_ when were reading, we tend to skip our eyes back and reflect on the word we just read. this slows us down. unfortunately, the only way to break this habit is to admit you do it and notice when you do. point at the text. one of the more surprising speed reading techniques is “meta(元) guiding.” _19_ you still need to concentrate on each word if you want to actually keep any information, but its one way speed reading programs teach you to quickly get through a text. _20_ while some people can certainly retain a lot of the information they read, many people cant. so, if youre interested, give speed reading a try, but dont feel like you have to commit to it just to get through all your books. you have other options. a. avoid “back skips”b. speed reading isnt for everyone. c. it is all about reading as fast as you can d. this simply means pointing at the text as you read it. e. another method is to repeat “a-e-i-o-u” as you readf. breaking that habit can dramatically increase reading speed. g. you can teach yourself speed reading with a web app like speeder. 第二节 完形填空 阅读下面的短文，从短文后各题所给的四个选项中（abcd）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。 like any good mother, when karen found out that another baby was on the way, she did what
