Building Trust in a Relationship AgainTrust is a learned behavior that we gain from past experiences. 36.___________ Trust is a risk. But you can’t be successful when there’s a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.Unfortunately, we’ve all been victims of betrayal. Whether we’ve been stolen from, lied to, misled, or cheated on, there are different levels of losing trust. Sometimes people simply can’t trust anymore. 37. __________ It’s understandable, but if you’re willing to build trust in a relationship again, we have some steps you can take to get you there.◆38. ___________ Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.◆39. ___________ If you’ve been betrayed, you are the victim of your circumstance. But there’s a difference between being a victim and living with a “victim mentality”. At some point in all of our lives, we’ll have our trust tested or violated.◆You didn’t lose “everything”. Once trust is lost, what is left? Instead of looking at the situation from this hopeless angle, look at everything you still have and be thankful for all of the good in your life. 40. ___________ Instead, it’s a healthy way to work through the experience to allow room for positive growth and forgiveness.A. Learn to really trust yourself.B. It is putting confidence in someone.C. Stop regarding yourself as the victim.D. Remember that you can expect the best in return.E. They’ve been too badly hurt and they can’t bear to let it happen again.F. This knowledge carries over in their attitude toward their future relationships.G. Seeing the positive side of things doesn’t mean you’re ignoring what happened.答案：BEACGSecret codes (密码) keep messages private. Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.People have used secret codes for thousands of years. 36 Code breaking never lags (落后) far behind code making. The science of creating and reading coded messages is called cryptography.There are three main types of cryptography. 37 For example, the first letters of “My elephant eats too many eels” s pell out the hidden message “Meet me.”38 You might represent each letter with a number, for example. Let’s number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, the message “Meet me” would read “13 5 5 20 13 5.”A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 39 For example, “bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me.” 40 However, it is also hard to keep a code book secret for long. So codes must be changed frequently.A. It is very hard to break a code without the code book.B. In any language, some letters are used more than others.C. Only people who know the keyword can read the message.D. As long as there have been codes, people have tried to break them.E. You can hide a message by having the first letters of each word spell it out.F. With a code book, you might write down words that would stand for other words.G. Another way to hide a message is to use symbols to stand for specific letters of the alphabet.答案：DEGFAIf anyone had told me three years ago that I would be spending most of my weekends camping. I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me. 36 .The friends who introduced me to camping thought that it meant to be a pioneer.37 We sleep in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.I was, nevertheless, talked into going on another fun-filled holiday in the wilderness. 38 Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.39 We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.40 It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.A. This time there was no tent.B. Things are going to be improved.C. The trip they took me on was a rough one.D. I was to learn a lot about camping since then,however.E. I must say that I have certainly come to enjoy camping.F. After the trip, my family became quite interested in camping.G. There was no shade as the trees were no more than 3 feet tall.答案：DCAFEColor is fundamental in home design — something you’ll always have in every room. A grasp of how to manage color in your spaces is one of the first steps to creating rooms you’ll love to live in. Do you want a room that’s full of life? Professional? Or are you just looking for a place to relax after a long day? 36 , color is the key to making a room feel the way you want it to feel.Over the years, there have been a number of different techniques to help designers approach this important point. 37 , they can get a little complex. But good news is that there’re really only three kinds of decisions you need to make about color in your home: the small ones, the medium ones, and the large ones.38 . They’re the little spots of color like throw pillows, mirrors and baskets that most of us use to add visual interest to our rooms. Less tiring than painting your walls and less expensive than buying a colorful sofa, small color choices bring with them the significant benefit of being easily changeable.Medium color choices are generally furniture pieces such as sofas, dinner tables or bookshelves 39 . They require a bigger commitment than smaller ones, and they have a more powerful effect on the feeling of a space.The large color decisions in your rooms concern the walls, ceilings, and floors. Whether you’re looking at wallpaper or paint, the time, effort and relative expense put into it are significant. 40 .A. While all of them are usefulB. Whatever you’re looking forC. If you’re experimenting with a colorD. Small color choices are the ones we’re most familiar withE. It’s not really a good idea to use too many small color piecesF. So it pays to be sure, because you want to get it right the first timeG. Color choices in this range are a step up from the small ones in two major ways答案：BADGFIs Fresh Air Really Good for You?We all grew up hearing people tell us to ＂go out and get some fresh air＂.36 According to recent studies, the answer is a big YES, if the air quality in your camping area is good.37 If the air you’re breathing is clean —which it would be if you’re away from the smog of cities —then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles（肌肉）and your brain.Recently, people have begun studying the connection between the natural world and healing（治愈）. 38 In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood（情绪）. Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 39 It gives us a great feeling of peace.40 While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D —but still protect your skin —put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D.A. Fresh air cleans our lungs.B. So what are you waiting for?C. Being in nature refreshes us.D. Another side benefit of getting fresh air is sunlight.E. But is fresh air really as good for you as your mother always said?F. Just as importantly, we tend to associate fresh air with health care.G. All across the country, recovery centers have begun building Healing Gardens.答案:36. E 37. A 38. G 39. C 40. DA Few Tips for Self-AcceptanceWe all want it to accept and love ourselves. But at times it seems too difficult and too far out of reach. 36 Here’s a handful of ways that will set you in the right direction.● 37 Do not follow the people who make you feel not-good-enough. Why do you follow them? Are you hoping that eventually you will feel empowered because your life is better than theirs? Know that your life is your own;you are the only you in this world.●Forgive yourself for mistakes that you have made. We are often ashamed of our shortcomings, our mistakes and our failures. 38 You will make mistakes, time and time again. Rather than getting caught up in how you could have done better, why not offer yourself a compassionate (有同情心) response? ＂That didn’t go as planned. But, I tried my best.＂●Recognize all of your strengths. Write them down in a journal. Begin to train your brain to look at strength before weakness. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today.39●Now that you’ve listed your strengths, list your imperfections. Turn the page in your journal. Put into words why you feel unworthy, why you don’t feel good enough. Now, read these words back to yourself. 40 Turn to a page in your journal to your list of strengths and achievements. See how awesome you are?A. Feeling upset again?B. Where do you start?C. Nothing is too small to celebrate.D. Remember, you are only human.E Set an intention for self-acceptance.F. Stop comparing yourself with others.G. When does the comparison game start?答案：36. B 37. F 38. D 39. C 40. ATraining for a marathon requires careful preparation and steady, gradual increases in the length of the runs. ___36___, buy the best-fitting, best-built running shoes you can find. No one can say which brand will work best for you or feel best on your feet, so you have to rely on your experience and on the feel of each pair as you shop. When you have found shoes that seem right, walk in them for a few days to double-check the fit. ___37___. As always, you should stretch (伸展) at least ten minutes before each run to prevent injuries.During the first week, do not think about distance, but run five minutes longer each day. ___38___, it is wise to take a day off to rest. But during the next week, set a goal of at least a mile and a half per run. ___39___. After two weeks, start timing yourself. ___40___. Depending on the kind of race you plan to enter,you can set up a timetable for the remaining weeks before the race.A. After six daysB. For a good marathon runnerC. Before you begin your trainingD. With each day, increase the distance by a half mileE. If they still feel good,you can begin running in themF. Time spent for preparation raises the quality of trainingG. Now you are ready to figure out a goal of improving distance and time答案：CEADGA garden that’s just right for youHave you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts?36 . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.● 37Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料). 38 . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.●Recall(回忆) your childhood memoriesOur model of what a garden should be often goes back to childhood. Grandma’s rose garden and Dad’s vegetable garden might be good or bad, but that’s not what’s important. 39 ― how being in those gardens made us feel. If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth. 40 . Then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.A. Know why you gardenB. Find a good place for your own gardenC. It’s our experience of the garden that mattersD. It’s delightful to see so many beautiful flowersE. Still others may simply enjoy being outdoors and close to plantsF. You can produce that kind of magical quality in your own garden, tooG. For each of those gardens, write down the strongest memory you have答案：36. F 37. A 38. E 39. C 40. GInterruptions are one of the worst things to deal with while you’re trying to get work done. 36 , there are several ways to handle things. Let’s take a look at them now.37 . Tell the person you’re sorry and explain that you have a million things to do and then ask if the two of you can talk at a different time.When people try to interrupt you, have set hours planned and let them know to come back during that time or that you’ll find them then. 38 . It can help to eliminate (消除) future interruptions.When you need to talk to someone, don’t do it in your own office. 39 , it’s much easeier to excuse yourself to get back to your work than if you try to get someone out of your space even after explaining how busy you areIf you have a door to your office, make good use of it. 40 . If someone knocks and it’s not an important matter, excuse yourself and let the person know you’re busy so they can get the hint (暗示) than when the door is closed, you’re not to be disturbed.A. If you’re busy, don’t feel bad about saying noB. When you want to avoid interruptions at workC. Set boundaries for yourselfas your time goesD. If you’re in the other person’s office or in a public areaE. It’s important that you let them know when you’ll be availableF. It might seem unkind to cut people short when they interrupt youG. Leave it open when you’re available to talk and close it when you’re not答案：BAEDGIf you are already making the time to exercise, it is good indeed! With such busy lives, it can be hard to try and find the time to work out. 36 Working out in the morning provides additional benefits beyond being physically fit.● Your productivity is improved. Exercising makes you more awake and ready to handle whatever is ahead of you for the day. 37● Your metabolism (新陈代谢) gets a head start. 38 If you work out in the mornings, then you will be getting the calorie (卡路里) burning benefits for the whole day, not in your sleep.● 39 Studies found that people who woke up early for exercise slept better than those who exercised in the evening. Exercise energizes you, so it is more difficult to relax and have a peaceful sleep when you are very excited.● 40 If you work out bright and early in the morning, you will be more likely to stick to healthy food choices throughout the day. Who would want to ruin their good workout by eating junk food? You will want to continue to focus on positive choices.There are a lot of benefits to working out, especially in the mornings. Set your alarm clock an hour early and push yourself to work out! You will feel energized all day long.A. You will stick to your diet.B. Your quality of sleep improves.C. You prefer healthy food to fast food.D. There is no reason you should exercise in the morning.E. You can keep your head clear for 4-10 hours after exercise.F. After you exercise, you continue to burn calories throughout the day.G. If you are planning to do exercise regularly, or you’re doing it now, then listen up!答案：36. G 37. E 38. F 39. B 40. AImagine a child standing on a diving board four feet high and asking himself the question: "Should I jump? " This is what motivation or the lack of it can do. Motivation and goal setting are the two sides of the same coin. 36 Like the child on the diving board, you will stay undecided.37 More than that, how should you stay motivated to achieve the goal? First, you need to evaluate yourself, your values your strengths, your weaknesses, your achievements, your desires, etc. Only then should you set your goals.You also need to judge the quality and depth of your motivation. This is quite important, because it is directly related to your commitment. There are times when your heart is not in your work. 38 So, slow down and think what you really want to do at that moment. Clarity（清晰）of thoughts can help you move forward.Another way of setting realistic goals is to analyze your short and long term objectives, keeping in mind your beliefs, values and strengths. Remember that goals are flexible.39 They also need to be measurable. You must keep these points in mind while setting your goals.Your personal circumstances are equally important. For example, you may want to be a Pilot but can’t become one because your eyesight is not good enough.40 You should reassess your goals, and motivate yourself to set a fresh goal.You will surely need to overcome some difficulties, some planned, but most unplanned. You cannot overcome them without ample motivation. Make sure that you plan for these difficulties at the time of setting your goals.A. This can affect your work.B. So how should you motivate yourself?C. However, this should not discourage you.D. So why should we try to set specific goals?E. They can change according to circumstances.F. Motivation is what you need most to do a good job.G. Without motivation, you can neither set a goal nor reach it.答案：GBAECEmoji（表情符号）and Workplace CommunicationIn Asia, messaging platforms are growing rapidly, with users in the hundreds of millions, both at work and play.36. It’s been reported that 76 percent of employees in some western countries are using emojis at work.Written communications can often read as cold and dull. Using emojis can add humor and feeling, keeping intention clear. 37, encouraging better and more frequent communication.In any given office, employees can range from age 22 to 70 and beyond, and finding common ground in communication style can be a challenge. 38. While the younger generations prefer to communicate visually, for those used to working with traditional tools like email, it may feel like a learning curve（曲线）. The good news is that it’s simple to learn and can be worth the effort.There is also the matter of tone（语气）. Who hasn’t received an email so annoying that it ruined an entire day? 39. Emoji can help communication feel friendlier, and even a serious note can be softened with an encouraging smile.40, and emoji can contribute directly to that positive outcome. And when your employees begin adding smiling emojis to their business communication, you’ll know you have succeeded in improving your work culture.A. Message with emojis feel more conversationalB. Even a formal email can seem cold and unfriendlyC. Sending smiling faces to colleagues may seem strangeD. The popularity of these platforms is spreading globallyE. Giving employees the tools enables them to communicate honestlyF. Studies show that friendlier communication leads to a happier workplaceG. An easy way to bring all work generations together is with a chat platform答案：DAGBFEveryone knows that fish is good for health. 36 But it seems that many people don’t cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn’t difficult. 37 This text is about how to buy and cook fish in an easy way.38 Fresh fish should smell sweet: you should feel that you’re standing at the ocean’s edge. Any fishy or strong smell means the fish isn’t fresh. 39 When you have bought a fish and arrive home, you’d better store the fish in the refrigerator if you don’t cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn’t as tasty as the fresh one.There are many common methods used to cook fish.40First, clean it and season it with your choice of spices (调料). Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it’s ready to serve.A. Do not buy it.B. The easiest is to steam it.C. This is how you can do it.D. It just requires a little knowledge.E. The fish will go bad within hours.F. When buying fish, you should first smell it.G. The fats in fish are thought to help prevent heart disease.答案：36. G 37. D 38. F 39.A 40.BLots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock36 Here is how to make one.● 37 In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.●Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 38 That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.●Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found.39●Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record. 40 If not, take another look at other methods you could try.A. Get a sleep specialist.B. Find the right motivation.C. A better plan for sleep can help.D. And consider setting a second alarm.E. If the steps you take are working, keep it up.F. Stick to your set bedtime and wake-up time, no matter the day.G. Reconsider the 15 minutes you spend in line at the café to get coffee.答案：36. C37. B38. G39. F40. EBefore there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.36 We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time.“I adore dancing,” says Lester Bridges, the owner of a dance studio in Iowa. “I can’t imagine doing anything else with my life.” Bridges runs dance classes for all ages. “Teaching dance is wonderful. 37 It’s great to watch them. For many of them, it’s a way of meeting people and having a social life.”38 “I can tell you about one young couple,” says Bridges. “They’re learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile. 39 ”So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, “Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better. 40 I find it hard to stop! Dancing reminds me I’m alive.”A. So why do we dance?B. Dance in the U.S. is everywhere.C. If you like dancing outdoors, come to America.D. My older students say it makes them feel young.E. I keep practicing even When I’m extremely tired.F. Dancing seems to change their feeling completely.G. They stayed up all night long singing and dancing.答案：BDAFEIn an online class, developing healthy patterns of communication with professors is very important. 36 While I have only listed two of each, these are obviously many other situations that can arise. Students should be able to extend the logic（逻辑）of each to their particular circumstance.Do's• 37 Questions about subject content are generally welcomed. Before asking questions about the course design, read the syllabus（教学大纲）and learning management system information to be sure the answer isn't hiding in plain sight.• Participate in discussion forums（论坛）, blogs and other open-ended forums for dialogue. 38 Be sure to stay on topic and not offer irrelevant information. Make a point, and make it safe for others to do the same.Don'ts• Don't share personal information or stories. Professors are not trained nurses, financial aid experts or your best friends. If you are in need of a deadline extension, simply explain the situation to the professor. 39• Don't openly express annoyance at a professor or class. 40 When a student attacks a professor on the social media, the language used actually says more about the student. If there is truly a concern about a professor's professionalism or ability, be sure to use online course evaluations to calmly offer your comments.A. That's what they are for.B. Turn to an online instructor for help.C. If more information is needed, they will ask.D. Remember that online professors get a lot of emails.E. Below are some common do’s and don’ ts for online learners.F. Everyone has taken a not-so-great class at one time or another.G. Ask questions, but make sure they are good, thoughtful questions.答案：36.

Some common things people will put on a gift registry include kitchen tools like knives and things like curtains. Even if there isn't a registry, a good housewarming gift is something to decorate the new house with, like a piece of art or a plant.___38 This is often appreciated since at a housewarming there isn't a lot of food served. There are usually no planned activities like games at a housewarming party. The host or hostess of the party will, however, probably give all the guests a tour of their new home. Sometimes, because a housewarming party happens shortly after a person moves into their new home, people may be asked to help unpack boxes. 39Housewarming parties get their name from the fact that a long time ago people would actually bring firewood to a new home as a gift. 40 Now most homes have central heating and don't use fires to keep warm.A.

MuzakThe next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? 71 It’s similar to the music you listen to, but it’s not exactly the same. That’s because thi s music was especially designed to relax you, or to give you extra energy. Sometimes you don’tevenrealize the music is playing, but you react to the music anyway.Quiet background music used to be called "elevator ( 电梯) music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name "Muzak". About one-third of the people in America listen to "Muzak" everyday. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. 72If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don’t want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? 73Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. 74 Supermarket shoppers buy 38 percent more groceries.75 . They say it’s boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!A. Some people don’t like Muza k.B. The music gives them extra energy.C. Music is playing in the background.D. Factory workers produce 13 percent more.E. Muzak tends to help people understand music better.F. They get as much as $4 million a year if their songs are used.G. Muzak is played in most of the big supermarkets in the world.CBFDA【练习 1】Friends play an important part in our lives， and although we may take the fact of friendship for granted, we often don’t clearly understand how we make friends. While we get on well with a number of people, 71 ．Moreover, a great many relationships come under the general term “friendship”． In allcases，two people like one another and enjoy being together， but beyond that， the degree of closeness between them and the reasons for their interest in each other change greatly．At the beginning, much depends on how people meet， and on good first impressions. As we get to know people, 72 . Although these factors are not of the greatest importance， it is more difficult to have a good relationship with people when there is a big difference in age and background．Then, 73 ． Friends will stand closer together and will spend more time looking at each other than ordinary friends．Smiles and soft voices also express friendliness，and it is because they may give the wrong signals that shy people often have difficulty making friends. A friendly look with a wrong facial expression can turn into an unfriendly stare，and nervousness may be wrongly understood as unfriendliness．Some relationships are a result of argument and discussion，but it is usual for close friends to have the same ideas and beliefs，the same opinion and interests. The more closely involved people become．the more they depend on each other. And 74 . Equally, friends have to learn to make allowances for each other, to put up with annoying habits， and to accept differences in opinion.In contrast with marriage, 75 . But the support and understanding that results fro m shared experiences and affections does seem to create a close and lasting relationshipA． we are usually friends with only a fewB． many factors can affect friendship and relationshipC． people want to do friends favors and hate to let them downD． argument and discussion can improve personal relationshipsE．we consider things like age，race，looks，economic and social status，etcF．we pay attention to actual behavior， facial expression， and the way a person speaksG． there a re no friendship ceremonies to strengthen the relationship between two people【练习 2】Speaking in public is most people’s least favorite thing. The reason is that we are all alraid of making foods of ourselves. 66 .But stop biting your finger-mails. Public spea king is easy . It’s just plain talking, and you talk all the time. Although I’m basically shy (honest!). I’ve been making speeches and talking on radi o and television for more than 30 years. And I can tell you that public speaking is not a“gift”like musical talent． 67_ .Here are some of the lessons I have learned :Your aud ience is going to come away with one or two of your main ideas． One or two． Not ten or twenty． 68 ． And if you don't have a clear idea of what you want to say, there's no way vour audience will． 69 ___—how you are going to open, what major points you want to make and how you're going to close．When I do a radio or TV piece, I often write the last sentence first． 70 ． A strong close is critical; the last thing you say is what your audience will most likely remember．The standard length of a vaudeville act is usually 12 minutes． If all those performers singing and dancing their hearts out couldn't go on longer without boring the audience, what makes you think you can?A． Some people are bom to be good at making speechB． Anybody who can talk can speak in publicC． Try to relax yourself before making the speechD． The more important the speech is, the more frightened we becomeE． It you can't express in a sentence or two what you intend to get across, then your speech isnot focused well enoughF． When you know where you're headed, you can choose any route to get thereG． No matter how long or short your speech is, you've got to get your ducks in a rowPart two 真题在线Passage 1：(2014 年全国 1 卷)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Personalized ExerciseAs the start of every year, many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class. But finally many of us just struggle to fit exercise into our lives, or start off well and then give up. Why do we have a good plan at the beginning and fail to achieve it in the end? How can we deal with the problem? 1．It is important to determine your motivation first. Are you mainly interested in de-stressing or in getting fitter? If your goal is relaxation, then ask yourself if you want to do it energetically. 2．If you have a calmer style, you can do something quite different. You could choose solitary exercise, such as walking the dog or doing some gardening. 3．There are quite a lot of them, such as walking and running groups, dance classes, etc. On your own, you could go horse riding or swimming, or just download fitness exercise programs and do it at home.4．If you have free time at the weekend, you could book some time with a personal trainer, who can come to your house, or you could meet him at the gym. If your life is not as regular, you could choose the next couple of minutes you have to try an exercise DVD, or put your running shoes on and run for any length of time.As you see, everything counts when you are doing exercise. Whatever your lifestyle is, you will be able to have something that suits you. 5．Just sit down with a cup of tea, read this article again, and have a think about your options. Then finish the tea, get up, get going, and don’t stop.A. Good exercise is necessary for physical health.B. The key could be to find the right type of exercise.C. If it is fitness you are after, group activities will be suitable.D. You’d better create a personalized plan to get you into shape.E. In this case, a type of exercise based on boxing may be right for you.F. In other words, you can always find personalized exercise by yourself.G. For people who are extremely busy, it is easier to fit exercise into daily lives.【答案】1．B2．E3．C4．G5．F【解析】1．B根据上文提到But finally many of us just struggle to fit exercise into our lives, or start off well and then give up. Why do we have a good plan at the beginning and fail to achieve it in the end? How can we deal with the problem?最后要么是很好的开始，最终放弃，为什么我们在开始有个好的计划最终不能实现，我们如何处理这些问题，故选B 关键是找到合适的练习的类型。
