    A Charlotte N.C. man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. Can the guy be held responsible for the woman’s death? Prosecutors (公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime—even if he or she doesn’t kill someone on purpose.
    But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.
    Absolutely, no question about it.
    The body has a natural protective method called the fight-or-flight response, which was originally described by Walter Cannon，chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the automatic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to early humans. However, in the modern world there is obvious decline of the fight-or-flight response.
    The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is poisonous in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death.
    By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in excitement or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead.
    小题1:What is Martin Samuels’ attitude to the possibility of being frightened to death?
    A．Approval.B．Disapproval.C．Doubtful.D．Indifferent.
    小题2:What can we learn about the fight-or-flight response according to the passage?
    A．The fight-or-flight response was raised and proved by Martin Samuels.
    B．It is a natural protective method that can’t be found in all creatures but humans.
    C．The ancient humans had a better fight-or-flight response than modern ones.
    D．The fight-or-flight response is beneficial to both our actions and organs.
    小题3:What activity can we infer is less likely to damage the organs?
    A．Winning an unexpected fortune.
    B．Missing a dead family member.
    C．Watching a horror movie.
    D．Listening to a sweet song.
    小题4:The purpose of the passage is ______.
    A．to explain why people will die of a heart attack
    B．to offer some advice on protecting us from heart failure
    C．to compare different kinds of feelings to cause a death
    D．to show strong emotions can cause a sudden death

    Collecting information about pre-employment and filling out an application form are closely connected, However, filling out an application form is much easier because you have total control and have enough time to think and plan.
    　　That you are given a form to fill out does not necessarily mean that you have to answer all the questions in it. If the form contains unclear questions or terms and conditions, you can make some changes before signing(签约)it, or refuse to answer some of the questions. What you must realize is that those terms and conditions have been written by highly paid lawyers. Each word is important, or it would not be there; and you can be sure that there is not anything there that is written with your interests in mind.
    　　I know what I speak of because, as a lawyer for Litton Industries. I wrote the terms and conditions that were printed on the back of order forms, I wrote the most tiring terms and conditions anyone has ever seen. Still, 90 percent of the buyers would just sign on them without questioning anything. If anyone questioned them, we would reach an agreement on something that was acceptable to both sides.
    　　So when you see a preprinted application that contains questions or terms and conditions, read it all and read it slowly. If you don’t like something, you can simply change the parts you don’t like, Remember that everything can be settled by discussion. To what degree it can be settled depends on your position, of course, and that is something only you can determine.
    小题1:Filling out application forms is much “easier” because_______.
    A．everything connected with application forms is easier
    B．you can control the form filling with enough time
    C．you can plan and have control of the needed time
    D．it is easier to collect information about pre-employment
    小题2:We can learn from the underlined part “Each word is important” that _______.
    A．questions in a form must be answered
    B．everything in a form must be read carefully
    C．the conditions that interest you are changeable
    D．something of your interests is most important
    小题3:It can be inferred from the 4th paragraph that_______.
    A．you must change a preprinted application before it is discussed
    B．questions in a form are more important
    C．you have little right to determine the conditions you like most
    D．it depends on yourself to settle things in a form

    You might say that one reason why Barack Obama is president of the US is that he knows how to give a good speech.
    Since 2004, Obama has written and delivered thousands of speeches. These are usually praised for two reasons: he treats the audiences like intelligent（有智慧的） adults, and he is able to express complicated ideas in an easy, natural way.
    Before becoming president, Obama was a lawyer, a college professor, and a successful writer---his two memories have become best-sellers.
    What’s more, he has some secret weapons.
    Teleprompter: Obama doesn’t go anywhere without his Teleprompter. The textbook-sized panes of glass holding the president’s prepared remarks follow him wherever he goes to speak.
    Writing team: Obama has a team of people who write his speeches. The writers chat with Obama for hours about what he wants to say. They listen to recordings of past presidential speeches and seek advice from advisers. Obama usually edits(编辑)and rewrites the drafts(草稿)several times.
    Tricks for lighthearted speeches:
    Make fun of the guests: Obama starts his speech by gently teasing his guests. His opening lines draw the audience’s attention while giving them an opportunity to relax and laugh at themselves and each other.
    Make fun of yourself: A good rule for speechmakers: If you’re going to make a joke about someone else, be sure to make one about yourself, too. Obama mocks(嘲弄) his own poor choices for filling the position of Commerce Secretary, saying, “No president in history has ever named three Commerce Secretaries this quickly.” In fact, his first two nominees（被提名人）for the position withdrew(撤出) their names for different reasons. In a process that had otherwise gone smoothly, the Obama Administration found it hard to deal with the problem of filling the Commerce seat.
    小题1:Obama made the poetic and inspiring speech in 2004 as________.
    A．presidentB．a nominee for the presidency
    C．a senatorD．a secretary
    小题2:What’s the meaning of the underlined word in paragraph 2?
    A．Difficult to understand.B．Easy to understand.
    C．Different from others.D．Interesting to say.
    小题3:From the passage, we know that Obama’s secret weapons are all these EXCEPT ____.
    A．a writing teamB．a teleprompterC．humorD．motivation
    小题4:What’s the best title of the passage？
    A．Secrets of Obama’s successful speeches.
    B．Obama’s successful speeches.
    C．Obama’s way of making speeches.
    D．Problems of Obama’s speeches.

    I woke up this morning. There is an empty feeling that I have had so many times before and it seems to be coming back into my mind. What is it? I can’t figure it out.
    I got ready for work. On the way I decide to stop and get a cheese from the little shop just down the road. I have never been there before but I was hungry and it would be 5 hours before I got off work.
    The owner of the store took my order. He asked me what I wanted and I told him I heard he made a great cheese. He seemed pleased to hear that.
    As I was sitting in the small space，there was an elderly gentleman finishing his breakfast. He paid the waitress, received this change and made a small joke. As he turned to get up, which was quite a difficult feat for this gentleman, he looked over at me. I gave a small smile.
    He looked again in my direction for a moment and said to me, “Has anyone ever told you, you have the most beautiful brown eyes?”
    Seeing as I have blue eyes, I can’t say I have ever heard that before. I humored him and said, “No, I can’t say anyone has ever told me that before.”
    He smiled, and said,“Well since they are blue you wouldn’t have heard that, but you have beautiful blue eyes.”
    I laughed and said thank you very much. He began to tell me a few one liner jokes so I smiled and laughed at his jokes.
    He tried to get up to leave again and looked at me and said“Your smile really brightens a room, do you know that?”I said,“Thank you very much.”
    He proceeded to get up, which took him quite some time. As he got up he said,“Take care of that smile.”
    I felt a sense of comfort wash over me and I reflected on my morning and that empty feeling I had. For a moment in time it seemed to be filled.
    小题1:Before the writer went to work, he felt________.
    A．sleepyB．energeticC．sickD．unhappy
    小题2:From the text, we can infer the old man __________.
    A．was optimistic about lifeB．liked to play a joke on others
    C．was unwilling to leaveD．had difficulty in hearing
    小题3:By saying“since they are blue”, the old man meant“_____________”.
    A．because they feel coldB．because they are sad
    C．because they have blue eyesD．because they are hungry
    小题4:What lesson can we learn from the story?

    C．We should laugh off our worries in life
    D．We should show respect to the old people.

    You have a nice salary, but you still feel short of money. At the end of each month, you often ask yourself, “Where has all my money gone”? To help you better run your salary, here come some money-saving tips.
    First, you need to set goals to encourage yourself to save money. For example, you plan to have a good dress in one year, to have a car in two years’ time or to buy a house in five years.
    Second, form money-saving habits and stay away from the ones that waste money. Learn to keep a diary of how much you spend and what it’s for. Think twice before using money on expensive skin care products(护肤品). The best way to keep your skin in good condition is enough sleep.
    Third, pay attention to your daily things. Leave no more than one light on when you leave home. Buy vegetables from a market where vegetables are less expensive and fresher, not a supermarket. When going to a supermarket, take a notebook with you. Write down what you want to buy.
    Fourth, save your social life. Take the dishes that haven’t been eaten up away for next day when you have dinner in a restaurant. When it’s your turn to offer a meal, invite your friends to your home, and cook the dinner yourself. If you are to attend a party and an expensive present is needed, ask several friends to go together to share a present.
    小题1:The passage is mainly about          .

    Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there’s a whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job’s pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:
    Do you prefer working alone or with other people? There are isolating(使孤立)jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
    How do you handle change? Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don’t happen so often. Other people would be bored of the same daily routine.
    Do you enjoy working with computers? I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you’ll likely find a lot of positions somewhere in the middle as well.
    ________________________________? This can range from being in a large building with a lot of people you won’t know immediately to a smaller setting where you’ll get to know almost all the people there fairly quickly.
    How do you like to get paid? Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.
    Anyway, these are a great starting point for you. I’ve seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.
    小题1:Which of the following is TRUE according to the passage?
    A．Isolating jobs usually drive people mad
    B．Interactive jobs make people shy easily.
    C．Extreme people tend to work with other.
    D．Almost everyone has a tendency in jobs.
    小题2: What does the underlined sentence in paragraph one mean?
    A．Before you select your job, you should assess your skills and match them with your position.
    B．There are more important things than assessing skills and match them with the position when you select a job.
    C．Nothing is important than assessing skills and match them with the position when you select a job.
    D．You should ignore your skills when you select a job.
    小题3: Which of the following sentences is suitable for the blank?
    A．What type of work environment do you enjoy?
    B．What kind of people do you like to work with?
    C．How can you fit in with your workmates?
    D．Do you want to be a big fish in a small pond?
    小题4:What is the best title for this passage?
    A．Lifestyles and Job PayB．Jobs and Environment
    C．Job Skills and Abilities D．Personalities and Jobs
    小题5: What is the missing word about a job search in the following chart?
    A．Design.B．Changes.C．Cooperation.D．Hobbies.

    Whether in the workplace or on the football field, effective teamwork can produce amazing results. However, working successfully as a team is not as easy as it may seem. Effective teamwork certainly does not just happen automatically; it takes a great deal of hard work and compromise. There are a number of factors that must be in place to make a good team.
    Effective leadership is one of the most important factors of good teamwork. The team’s leader should possess the skills to create and preserve a positive working environment and motivate and inspire the team members to take a positive approach to work and be highly committed. An effective team leader will promote a high level of spirit and make them feel supported and valued.
    Communication is a vital factor of all interpersonal relationship and especially that of a team. Team members must be able to articulate their feelings, express plans and goals, share ideas and see each other’s opinions.
    Conflicts will arise no matter how well a team functions together. The best way to deal with conflicts is to have some organized methods of handling conflicts. Team members should be able to voice their concerns without fear of offending others. Instead of avoiding conflict issues, a hands-on approach that settles them quickly is much better. It is often advised that the team leader sit with the conflicting parties and help work out their differences without taking sides and trying to remain objective if possible.
    The team leader must set a good example to create good teamwork. In order to keep team members positive and committed and motivated, the team leader himself needs to show these qualities. The team turns to the leader for support and guidance. So any negative words or behaviors on the leader’s part can be disastrous.
    Regardless of what type of work you are in, knowing how to effectively work on and with a team is going to be extremely important to your success and that of your team.

    After six months of living in New Zealand, I realized one thing. Despite my  1  for greater contact with local students,  2  I initiated(开始) the contact, it wouldn’t happen. Local students are not interested in contacts with the international students, because they regard us as shy,  3   and sometimes snobby （势利的） people. Of course we know that’s not true. I want to change their opinions.
    After  4    the problem, I put on my “confidence mask” each morning and walked around with a smile on my face. I chatted with people whenever I had the chance. I showed that I was not afraid to  5    them, and that I was worthy of being a friend.
    A side-effect of my  6    confidence was that my emotions occasionally broke down Only in the  7    of my room, where no one could see, would I reveal my real emotions. All the rejections, funny looks, and  8    behind my back calling me a weirdo（古怪的人） melted  into tears. Once that was done, I would put on my confidence mask once again and start a new day.
    It finally worked  My name became known throughout the school as I appeared to be 9    and active. Slowly, I discovered that I no longer needed to put on my confidence mask. I had real   friends. Instead of dragging myself to school and  10   to be happy, I was truly happy. I could not believe it when I was elected to the student government as Deputy Head boy----the first international student to receive the title.
    From my  11    in New Zealand, I believe one thing will always be true: If you try your best to reach your goals, you’ll achieve your  12    dreams.
