    In summer, millions of people will head for the beach. And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
    “Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”
    Scientists are working on using that energy to make electricity．
    Most waves are created when winds blow across the ocean．“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said．“Waves are one of nature’s ways of picking up energy and then sending it off on a journey．”
    When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) ．The turbine can then power an electrical generator (发电机) ．
    The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．
    The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal．
    Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．
    Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．
    With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”
    In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
    68．Which of the following is NOT true?
    A．Wave power costs too much money．
    B．Wave energy creates the same amount of pollution as other energy sources．
    C．Wave power affects fishing and boat traffic．
    D．Wave power may affect marine animals．
    69．We can infer from the passage that ______．
    A．finding more new energy sources is not necessary because of wave energy
    B．wave energy is a resource that will never run out and is used all over the world
    C．wave power is perfect for creating energy around the world
    D．wave power doesn’t create any pollution
    70．The underlined word “drawbacks” probably means ______．
    A．regrets      B．adventures       C．disadvantages          D．difficulties
    71．What can be the best title for the passage? 
    A．How to Get Electricity by Waves．       B．The Advantages of Wave Energy.
    C．Can Waves Make Electricity?  D．The Disadvantages of Wave Energy．

    认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
    Speaking in public is most people's least favorite thing. The reason is that we are all afraid of making fools of ourselves. The more important the speech is, the more frightened we become. In fact, public speaking is not a "gift" like musical talent. Anybody who can talk can speak in public. Here are some of the lessons I have learned:
    Try to make your idea clear and brief. If you can't express what you intend to get across in a sentence or two, and then your speech is not focused well enough. If you don't have a clear idea of what you want to say, your audience will make no sense. After all, what you can impress your audience in your speech is one or two of your main ideas. One or two. Not ten or twenty.
    No matter how long or short your speech is, you've got to organize it well-how you are going to open, what major points you want to make and how you're going to close. A strong close is critical: the last thing you say is what your audience will most likely remember. When I do a radio or TV piece, I often write the last sentence first. When you know where you' re headed, you can choose any route to get there.
    Finally, you'd better limit the time of your speech as properly as you can to hold the audience's curiosity. Take a vaudeville act (杂耍) for example. The standard length of one is usually 12 minutes. Just imagine how you are feeling if you have been watching all the performers singing and dancing their hearts out for more than the standard time

    Our cat has a sweet nature, and she can let us know what she wants. When we fail to meet her needs, she gently leads us in the proper direction. When I forget to fill her water bowl early in the morning, she runs after my legs, and then pushes me in the direction of her bowl. She doesn’t get irritated (生气的); instead, she expresses her wishes in the best way. And I always understand what she is telling me.
    One day I found myself envying her simple expression. How many times had I expected my husband or my children to know my wants without my ever giving voice to them? How many times had I been disappointed that they couldn’t understand when I needed a hug, a compliment or a chocolate bar?
    After a pleasant afternoon with my husband, I wanted to stop somewhere nice and have dinner, but he didn’t understand my hints (暗示). “Couldn’t you see that I wanted to go out to dinner?” I complained when he pulled into our driveway.
    “Why didn’t you say so? I can’t read your mind,” he answered in impatience. His words gave me pause. Had I expected him to read my mind? Why hadn’t I expressed my desire more clearly? I realized I had fallen into the female trap of “If you love me, you can read my mind.”
    Now, I state my needs clearly and directly. I look at my cat and know she agrees.
    1. Why was the author disappointed in her husband or her children?
    A. Her husband didn’t give her a hug.       B. Her children didn’t give her a chocolate bar.
    C. They didn’t give her a compliment.       D. They didn’t understand her mind.
    2. What will the author do if she wants something from her husband now?
    A. She will give him her hints.            B. She lets him guess what she wants.
    C. She tells him her needs directly.        D. She buys what she wants herself.
    3. What can we learn from the underlined sentence in the fourth paragraph?
    A. I realized what I did was wrong.      B. My husband stopped me from saying something.
    C. I stopped and didn’t go with my husband.  D. My husband prevented me from going on.
    4. What would be the best title of the text?
    A. How does a cat ask for something?  B. Learn how to read your cat’s mind
    C. A lesson from a cat               D. Guess what others think

    For some time past it has been widely accepted that babies----and other creatures----learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的) “drive” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
    It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
    Paousek began his studies by using milk in the normal way to “reward” the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children’s response in situation where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “switched on a display of lights---- and indeed that they were able to learn quite complicated turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
    Papousek’s light display was placed directly in front of the babies and he made the interesting observation that sometimes they would turn back to watch the lights closely although they would “smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a primary human urge to make sense of the world and bring it under intentional control.
    72.According to the author, babies learn to do things which ____.
    A. are directly related to pleasure          B. will meet their physical needs
    C. will bring them a feeling of success          D. will satisfy their curiosity
    73.Papousek noticed in the studies that a baby ____.
    A. would make learned response when it saw the milk
    B. would carry out learned movements when it had enough to drink
    C. would continue the simple movements without being given milk
    D. would turn its head to right or life when it had enough to drink
    74.In Papousek’s experiment babies make learned movements of the head in order to ____.
    A. have the lights turned on              B. be rewarded with milk
    C. please their parents                   D. be praised
    75.According to Papousek, the pleasure babies get in achieving is a reflection of ____.
    A. a basic human desire to understand and control the world
    B. the satisfaction of certain physiological needs
    C. their strong desire to solve complex problem
    D. an important human urge to display their learned skills

    There’s a man in the habit of hitting me on the head with an umbrella. At first I couldn’t stand it; now I’m used to it.
    I don’t know his name. I know he’s ordinary in appearance, wears a gray suit and has a common face. One hot morning, when 1 was sitting on a tree-shaded bench in Palermo Park, reading the paper, suddenly I felt something touch my head. It was the very same man who now, as I’m writing, keeps striking me with an umbrella.
    So I turned around filled with anger. He just kept on hitting me. I asked him if he was crazy. He didn’t even seem to hear me. Then I threatened (威胁) to call a policeman. Calmly cool as a cucumber, he went on hitting me. After a few moments of hesitation (犹豫), and seeing that he was not about to change his attitude, I stood up and hit him on the nose. The man fell down. But he immediately got back on his feet, obviously with great effort, and without a word again began hitting me on the head with the umbrella. His nose was bleeding and, at that moment. I felt sorry for him I regretted having hit him so hard. After all, the man wasn’t exactly hitting me；he was only tapping me lightly with his umbrella, not causing any pain at all. Of course, those taps were extremely upsetting. As we all know, when a fly lands on your forehead, you don’t feel any pain；what you feel is annoyance (烦恼).  Well then, that umbrella was one huge fly that kept landing on my head time after time.
    Believing that I was dealing with a madman, I tried to escape. But the man followed me, wordlessly continuing to hit me. So I began to run (I should point out that not many people run as fast as I do). He ran after me, trying to hit me. The man was out of breath so that I thought, if I continued to force him to run at that speed, he would drop dead right then and there.
    64. When the man began to strike the author with an umbrella, the author_________
      A. became angry                  B. called the police
        C. turned around and escaped        D. turned around and fought back
    65. The author would most probably agree that the man was________.
        A. deaf          B. blind         C. dead         D. mad
    66. The author felt sorry for the man because _______.
       A. there was a fly on the man’s head     B. he hit the man so hard that his nose bled
     C. the man couldn’t catch up with him       D. the man formed a bad habit of beating others    
    67. It can be learned from the passage that the man__________.
     A. shouted loudly while hitting the author  B. wanted to tell the author something
     C. ran after the author breathlessly        D. acted as if he were a fly

    "Tear’em apart!" "Kill the fool!" "Murder the referee（裁判）!"
    They are common remarks one may hear at various sporting events. At the time they are made, they may seem innocent（无害的）enough. But let's not kid ourselves. They have been known to influence behavior in such a way as to lead to real bloodshed（流血）.Books have been written about the way words affect us. It has shown that words having certain meanings may cause us to react in ways quite foreign to what we consider to be our usual humanistic behavior. I see the term "opponent" as one of those words. Perhaps the time has come to delete it from sports terms.
    The dictionary meaning of the term "opponent" is "enemy":“ one who opposes your interests." Thus, when a player meets an opponent, he or she may tend to treat that opponent as an enemy. At such times, winning may control one's mind, and every action, no matter how bad, may be considered correct . I recall an incident in a handball game when a referee refused a player's request for a time out for a glove change because he didn't consider them wet enough. The player rubbed his gloves across his wet T-shirt and then shouted, "Are they wet enough now?"
    In the heat of battle, players have been observed to throw themselves across the court without considering the consequences that such a move might have on anyone in their way. I have also witnessed a player reacting to his opponent's intentional and illegal blocking by hitting him with the ball as hard as he could during the course of play. Off the court, they are good friends. Does that make any sense? It certainly gives proof of a court attitude which is different from normal behavior.
    Therefore, I believe it is time we promoted the game to the level where it is by setting an example. Replacing the term “opponent” with “ associate” could be an ideal way to start.
    The dictionary meaning of the term “associate” is “friend”；“companion.” Think it over！You may soon see and possibly feel the difference in your reaction to the term "associate' rather than "opponent."
    49. Which of the following statements best expresses the author's view?
    A. Bad behavior in sports will always have serious consequences.
    B. The words people use can influence their behavior.
    C. Unpleasant words in sports are often used by foreign athletes.
    D. Unfair judgments by referees will lead to violence on the sports field.
    50. Rough words are spoken during games because the players________.
    A. are too eager to win                   B. are usually bad-tempered  
    C. can't afford to be polite in competitions    D. treat their friends as competitors
    51. What did the handball player do when he was not allowed a time out to change his gloves?
    A. He refused to continue the game.
    B. He angrily hit the referee with a ball.
    C. He claimed that the referee was unfair.
    D. He wet his gloves by rubbing them across his T-shirt.
    52. The author hopes to have the current situation in sports improved by_______.
    A. changing the attitude of players on the sports field
    B. raising the referee's sense of responsibility
    C. calling on players to use clean language on the court
    D. regulating the relationship between players and referees

    Welcome every morning with a smile. Let your first hour set the theme of success and positive action that is certain to echo(回响) through your entire day. Today will never happen again. Don’t waste it with a false start or no start at all. You were not born to fail.
    Starting the day right can give good momentum (动力) for the rest of the day. Having a power morning is a key factor for a fruitful day. Here are some tips on getting the most out of the morning.
    Wake up early. In theory, there’s no difference in waking up early or late as long as you get the proper amount of sleep. However, there is a psychological advantage when you wake up earlier than the average person and then you’ll have more time to do preparation before engaging in the real world.
    Exercise. Good health is always a benefit with exercise, but studies have also shown that morning exercise helps you to sleep better at nights.
    Eat breakfast. It’s the most important meal of the day. According to the Mayo Clinic, we should choose three from the following four: fruits and vegetables, grains, dairy, and protein. Did you know that you can actually gain weight when you skip breakfast?
    Take a shower. When you shower, do you do it in the morning or at night? I used to shower in the evenings, but I found that morning showers helped me to be more smart.
    Prioritize (优先) your To-Do list. Leo coined the acronym(首字母缩略词) MIT to mean “most important tasks.” Our to-do list might be never ending, but put on top of the list a couple of urgent tasks that will define the day to be a successful one.
    Check your emails. Only once. Getting a lot of emails can be very distractive（分散精力的）. You actually are more productive when you check them only a few times at fixed time of the day. I only do them 2-3 times a day—once in the morning, once at lunch, and one more as it gets toward the end of the day.
    45. The purpose for the author to write this passage is to_______________.
    A. tell you to get up early every day
    B. offer you the best way to start the day
    C. give you advice about how to arrange a day
    D. advise you to prioritize your to-do list every morning
    46. If you don’t have breakfast, you may__________.
    A. lose weight.              B. be productive.    
    C. put on weight.            D. be more smart.
    47. The underlined word “coined” in Paragraph 6 mean__________.
    A. invented         B. designed          C. founded        D. defined
    48. The author advises you to check your emails only once because__________.
    A. the emails are not important
    B. reading e-mails is distractive
    C. you can only read e-mails at fixed time
