2018版高考英语(课标通用)大一轮复习课时作业：必修二_unit_3_computers(有答案)
课时作业(八)Ⅰ.阅读理解Today I want you to know Sadness can be a good friend.“All well and good，Master Yoda，” you say，“but how does that work？”First，Sadness is about losing something you care about，whether that's a loved one，a job，or a football game...So，Sadness shows you what you care about.Would you feel sad if your girlfriend / boyfriend left？The answer tells you how attached you are to this person.Along the same lines，experiencing the Sadness of loss helps us to appreciate what we still have.Funerals are painful occasions，and they are great for bringing people back together，burying old conflicts，healing wounds，but it only works if you show up and feel the Sadness and let it bring you together with the others there.One who can't bear Sadness will tend to shy away from love，commitment，and real passion，in order to avoid grief，and that's an empty life.Similarly，losing a job can help you appreciate that you still have your health.Losing your health can bring loved ones together.Losing money can help you to focus on what really matters to you，your values，your sense of mission，your spirituality.Lastly，Sadness has authenticity to it.Grieving has a way of slowing you down and bringing you back to the moment.It forces you to let go of your worries about your todo lis t and next quarter's numbers and your fastpaced life and really be with yourself，your feelings and the people around you.This is important today because we can get so lost in our smart phones and emails and lose sight of people，relationships，and dreams.So，Sadness is the kind of friend who can help you to stay grounded and real，to honor what's important and let go of what's not，and we all need that kind of friend.1．The best title for the text would be________.A．Why Sadness Is Your FriendB．How Sadness Works in Your LifeC．What Do You Think of SadnessD．Why You Feel Sad2．How many reasons why Sadness can be a friend are mentioned in the text?A．Only one. B．Two.C．Three. D．Five.3．The fourth paragraph is developed mainly by________.A．providing the examplesB．telling personal experiencesC．making comparisonsD．listing facts4．The word “It” in the last paragraph but one refers to________.A．Letting go of your worriesB．Bringing you back to the momentC．GrievingD．Fastpaced life答案：[解题导语]本文是一篇议论文。

Unit 2 Healthy eatingⅠ.阅读理解(2017· 英才大联考湖南师大附中月考)As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise.The line of thought involved in this shift can be pursed further.Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired.This person is not ill.He may not even be at risk for any particular disease.But we can imagine that this person could be a lot healthier.The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body's special needs.Both types have simply been called “well”．In recent years, however, some health specialists have begun to apply the t erms “well” and “wellness” only to those who are actively attempting to maintain and improve their health.People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body's condition.Most importantly, perhaps, people who are well take active responsibility for all matters related to their health.Even people who have a physical disease or handicap (缺陷) may be “well”， in this new sense, if they make an effort to maintain the best possible health they can in the face of their phys ical limitations.“Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for.People who are well are likely to be better able to resist disease and to fight disease when it strikes.And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life.1．Today's medical care is placing more stress on ________.A．keeping people in a healthy physical conditionB．monitoring patients' body functionsC．removing people's bad living habitsD．ensuring people's psychological wellbeing2．According to the passage, the true meaning of “wellness” is for people________.A．to best satisfy their body's special needsB．to strive to maintain the best possible healthC．to meet the strictest standards of bodily healthD．to keep a proper balance between work and leisure3．According to what the author advocates, which of the following groups of people would be considered healthy?A．People who have strong muscles as well as slim figures.B．People who are not presently experiencing any symptoms of disease.C．People who try to be as healthy as possible, regardless of their limitations.D．People who can recover from illness even without seeking medical care.答案与解析本文是一篇议论文，讨论了什么样的人才是真正意义上的健康的人。

Unit 2 Healthy eatingⅠ.阅读理解A(2017·湖北七市高三联合考试)Modern humans have a hard time controlling their desire to eat. Often you eat not because you are hungry, but because you are affected by many other things. How much you eat is strongly affected by how much those around you eat. People eating alone eat least. People eating with one other person eat 35 percent more than they do at home. People dining in a party of four eat 75 percent more. Eating with overweight friends? You'll eat more. Is your waitress overweight? you'll eat more.A wide variety of food? You'll eat more.Plates can decide how sweet dessert tastes. If people ate it off a paper plate, they'd say, “This is good.” If they ate it off a fancy silver plate, they would say, “This is the greatest cake I've eaten in my entire life.”Your knowledge about what makes food good or bad also affects how much you eat. You tend to eat more when you think the food is good, and less when you think it is bad. So Grandma's cookies always taste better than other coo kies. “Good food” even has a “health halo (光环) effect”. If we're eating something healthy, we feel that everything in that meal is healthy. Due to this, people often believe that a cheese cake with a salad has fewer calories (卡路里) than the cheese cake alone. That's perhaps also why eating organic (有机的) food might turn you into an annoying guy. Your brain may use anything that makes you feel good about your own morality to excuse your immoral behaviour.Food and hunger affect your judgment too. Hungry judges give more serious sentences. Kids who don't eat breakfast behave worse than kids who eat their breakfast. People who have low blood sugar are more likely than the average person to have trouble concentrating and controlling their unpleasant emotions.【解题导语】本文主要介绍了哪些因素会导致人们吃的更多。

Unit 2 Healthy eatingⅠ.阅读理解[2017·辽宁沈阳质检]It was a cold night in WashingtonD．C.，and I was heading back to the hotel when a man approached me.He asked me for some money so he could get something to eat.I'd read the sign：“Don't give money to beggars.” So I shook my head and kept marching.I wasn't prepared for a reply，but he said，“I am really homeless and I am really hungry！You can come with me and watch me eat！” But I kept on marching.The incident bothered me for the rest of the week.I had money in my pocket and it wouldn't have killed me to hand over a dollar or two even if he had been lying.On a freezing cold night，I still assumed the worst of a fellow human being.Flying back to Anchorage，I couldn't help thinking of him.I tried to seek excuses for my failure to help by assuming government agencies，churches and charities were there to feed him.Besides，you're not supposed to give money to beggars.Somewhere over Seattle，I started to write my weekly garden column for the Anchorage Daily News.Out of the blue，I came up with an idea.Bean's Cafe，the soup kitchen in Anchorage，feeds hundreds of hungry Alaskans every day.Why not try to get all my readers to plant one row in their gardens devoted to Bean's Cafe?Before long my idea took_off.People would fax me or call when they took something in.Those who only grew flowers donated them.Food for the spirit.And relief for my conscience.As more and more people started working with the “Plant a Row” concept，many companies gave free seeds to customers and displayed the logo，which also arose in national gardening publications.Row markers with the “Plant a Row” logo were distributed to gardeners to set apart their “Row for the Hungry”．It is unexpected that millions of Americans are threatened by hunger.If every gardener in America—and we're seventy million strong—plants one row for the hungry，we can lower the number of neighbors who don't have enough to eat.Maybe then I will stop feeling guilty about abandoning a hungry man I could have helped.1．Why did the author turn down the beggar's request?A．He was previously reminded not to do so.B．He was eager to march back to the hotel.C．He thought that it was beyond his duty.D．He was short of money at that moment.2．Which of the following is the closest to the underlined phrase “took off” (Paragraph 6)?A．We eventually took_off at 11 o'clock and landed in Seattle safely.B．To take_off pounds，you have to cut down the number of calories.C．On hearing the news，he took_off at once and headed back to the hotel.D．His business really took_off owing to his advanced management.3．What did the author do after the beggar's incident?A．He felt guilty but couldn't help him.B．He started a project to help the hungry.C．He ran a blue kitchen to supply the hungry with soup.D．He still supposed it was unwise to give money to beggars.4．What can be a suitable title for the passage?A．Plant a Row for the HungryB．Lend a Hand to BeggarsC．Never Hesitate to Help OthersD．Plan a Gardening Project答案：[解题导语]本文通过作者的一次经历告诉我们：只要人人都奉献出一点爱，我们的世界将变得更加美好。

Module 2 No DrugsⅠ. 阅读理解A(2016·四川D) 导学号 58082150A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.Researchers have discovered that “night milk” contains more melatonin (褪黑激素) , which has been proven to help people feel sleepy and reduce anxiety.The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.Night milk quickened the start of sleep and caused the mice to sleep longer.While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.Milk is also sugar－free and additive－free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.文章大意：这是一篇研究报告。

Unit 3 Inventors and inventionsⅠ.阅读理解A few weeks ago when I got closer to the classroom I heard laughter and drumming －my students obviously thought they had a free period! As I entered the classroom，the drumming stopped.“Good morning，Miss，” they tried to sound happy to see me；their faces were delighted but I knew this was not for me.“What are you all doing？” “Nothing，Miss.” Guilty eyes stared back at me.They pulled out books and sat and waited，but that_thing I had seen in their faces，that thing I had so hoped to bring with my teaching，that thing was slipping away now as they got ready for class.“Nothing? You were doing something.What？”There was quiet and I realized they thought I was angry.Eventually one of them said，“Columbus Day，Miss.You know，the day Columbus reached Trinidad with his ships.We are acting the Columbus Day play.”“Wait，you mean the same Columbus in the history? Christopher Columbus？”“Yes，Miss.”“But...well，we did that chapter in the book.You didn't answer my questions.”I felt my heart p ounding hard.“Open the book，come，quick，” I was excited now.“Okay，so who is taking part in the play? Come to the front.Let's act out this play.”“Miss，you said to open the book.We're not going to read？”“I will read，you will act and you will drum and you will see how the chapter and the play work together.”The students stared at me as if I were crazy.“Miss，for real？”“Yes，for real！”Had I hit upon something here? There was something I hadn't seen before －these faces－excited，smiling，alive.These faces were what I dreamed of! One week later I gave the students the same questions on Columbus that few had passed the first time and this time more than half the class passed!From this experience，I came to recognize that books are enough for some students，but for others life，as they know，has little to do with what's in the book unless they see a corelation.1．What were the students doing when the author got closer to the classroom?A．They were having a break.B．They were acting a play.C．They were throwing a party.D．They were reading history books.2．What does “that thing” in Paragraph 2 refer to?A．Guilt and regrets.B．Disappointment.C．Interest and passion.D．Satisfaction.3．What did the author ask the students to do in the class?A．Perform a play about Columbus.B．Retell the story of Columbus Day.C．Read one chapter in the book aloud.D．Answer questions based on the book.4．Which of the following can be the best title for the text?A．Think Outside the BookB．An Unforgettable ExperienceC．Education－the Key to IgnoranceD．A Special Celebration of Columbus Day答案：[解题导语]学生们的学习不仅仅在于课本，通过活动把生活与书本联系起来或许会让孩子们表达出自己的兴趣和热情，展露发自内心的笑容。
2018届高三英语(人教版)总复习课时作业2 含答案
课时作业2Ⅰ.阅读理解Have you ever found yourself in this situation: You hear a song you used to sing when you were a child—a bit of nostalgia(怀旧) or “blast from the past，” as we say. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago.Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages.Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of “listen-and-repeat” learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words.All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered.Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them.Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained in a catchy 3, or memorable 4, tune 5.Dr. Ludke said the findings could help those who struggle to learn foreign languages. On the University of Edinburgh's website Dr. Ludke writes, “This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area.”1．The “song”mentioned in the first paragraph is intended to ________.A．recall the pastB．attract the readersC．introduce the topicD．compare the childhood with the present2．According to the passage which language doesn't share the same root with Germanic or Romance languages?A．Hungarian. B．Spanish.C．Italian. D．English.3．Based on the last two paragraphs, we can conclude that ________.A．singing is the best way to learn a languageB．the brain probably works best when the foreign language learners sing the wordsC．a listen-repeat method is very effective for any language learner D．Dr. Katie Overy and Dr. Ludke disagree with each other4．In which situation can the finding of the research be applied?A．A mother is going to teach her baby how to speak.B．A child is going to have his first music lesson.C．A student is going to learn a new English song.D．An American is going to learn some Chinese.答案与解析本文讲述的是一项关于音乐和外语学习之间关系的研究。
