If so, then you’ve fallen 21_ to bad product placement (产品植入). Clever marketing folks want their products to be 22_ within a scene, but not the focus. When done correctly, product placement can add a sense of realism to a movie or television show.Product placement 23_ from as early as 1950s when a drinks company paid to have a character in the movie The African Queen toss loads of their product overboard. Since then, there have been countless placements in thousands of movies.Sometimes product placement just happens. A set dresser (布景人员) might think of something that 24_ the level of credibility or realism of the story. One example is the use of a can of ant killer in a violent fight scene in the popular television programme The Sopranos. A spokeswoman for the manufacturer said if the company had not been 25_ about the use of their product, they would not have given it a thumbs-up.Arranged product placement deals are more prevailing. The most common type is a simple exchange of the product for the placement. A deal is made; in exchange for the airtime, the cast and crew are provided with a(n) 26_ supply of the company's products.Sometimes, a gift of the product isn’t an appropriate form of compensation, so the deal27_with money works well. Someone from a manufacturer’s marketing team hears about a movie project, and approaches the set dresser with a(n) 28_ attractive proposal. They come to an agreement, and the product makes a number of 29_ casual appearances. Both teams a re happy. Before product placement really saw a rapid growth in the mid-1980s, it was pretty much ado- it-yourself 30_ . Now there are entire agencies that can handle the job. Some larger corporations will dedicate personnel to seek out opportunities for placement within films, television shows —even games and music.ClozeDirections: For each blank in the following passage there are four words or phrases marked A, B,C and D. Fill in each blank with the word or phrases that best fits the context.Stroke is the fourth leading cause of death among Americans, and a much larger 31 to chronic disability and healthcare costs than this ranking suggests. There’s32 question that preventing strokes is important. But a big question is how best to do so and in whom.Currently, some expert say, far too many people who are free of 33 that might herald ( 预示) a stroke are undergoing surgery to ream out carotid arteries ( 颈动脉) that feed the 34 , or are having stents ( 支架) inserted in these arteries, than is justified by availableevidence.and create a risk of serious complications like heart attack or , 36 stroke itself, even death; and drive 37 health care costs by billions of dollars a year.Based on the latest research , they 38 , most patients without symptoms like a39 stroke or transient ischemic attack ( 短暂性脑缺血发作) do as well---or nearly as well—with intensive medical therapy to 40 blood pressure, cholesterol and diabetes.“ Intensive medical therapy is a much 41 way to prevent stroke caused by clots(血块) than either surgery or stent mg(支架植入术) ,” said Dr. David Spence, a stroke prevention specialist at the University of Western Ontario.But surgeons, even those who 42 the limitations of current research, say carotid endarterectomy (颈动脉内切手术), as the reaming operation is called, is the treatment of choice for many patients with serious 43 in one or both carotid arteries.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose one that fits best according to the information given in the passage you have just read.( A )They say a cat has nine lives, and I think that possible since I am now living my third life and I’m not even a cat .My father died when I was 15, and we had a hard struggle to make a living .And my mother, who was seriously ill in her last years, died while still in her 60s .My sistermarried soon after, and I followed her example within the year .This was when I began to enjoy my first life .I was very happy, in excellent health .I had a good job in San Jose and a beautiful home up the peninsula in San Carlos .Life was a pleasant dream .Then the dream ended .I became afflicted (使苦恼) with a slowly progressive disease of the motor nerves, affecting first my right arm and leg, and then my other side .Thus began my second life… .In spite of my disease I still drove to and from work each day, with the aid of special equipment installed in my car .And I managed to keep my health and optimism, to a degree, because of 14 steps .Crazy? Not at all .Our home was an affair with 14 steps leading up from the garage to the kitchen door .Those steps were a standard measure of life .They were my yardstick, my challenge to continue living .I felt that if the day arrived when I was unable to lift one foot up one step and then drag the other painfully after it ---repeating the process 14 times, I would be through---I could then admit defeat and lie down and die .Then on a dark night in August, 1971, I began my third life .It was raining when I started home that night; strong winds and slashing rain beat down on the car as I drove slowly down one of the less-traveled roads .Suddenly the steering wheel jerked (猝然一动) .In the same instant I heard the bang of a blowout .It was impossible for me to change that tire! Utterly impossible!I started the engine and thumped slowly along, keeping well over on the shoulder until I came to the dirt road, where I turned in and where I found lighted windows welcomed me to a house and pulled into the driveway and honked the horn .The door opened and a little girl stood there .When she knew what happened to me, she went into the house and a moment later came out, followed by a man who called a cheerful greeting .I sat there comfortable and dry, and felt a bit sorry for the man and the little girl working so hard in the storm .About an hour later, the man’s voice was heard, “This is a bad night for car trouble, but you’re all set now .” “Thanks,” I said .“How much do I owe you?” He shook his head, “Nothing .Cynthia told me you were a cripple .Glad to be of help .I know you’d do the same for me .There’s no charge, friend .” I held out a five-dollar bill, “No! I like to pay my way .” He made no effort to take it and the little girl stepped closer to the window and said quietly, “Grandpa can’t see it .”46 ．“A cat has nine lives” here means ．A．a cat can live nine times longer than any other animalB．a cat can die ninthC．a lucky man can not die easilyD．the writer will live nine times47．What do you think of the man who helped change the tire?A．Warm-hearted but pitiableB．Warm-hearted and happyC．A blind old man that has nothing to do everyday．D．A poor old man that is always ready to helpothers．48．How will the story be ended?A．The writer paid the little girl but the old man did notaccept．B．The writer drove away with tears running down hischeek．C．The writer stayed there, without knowing what to do and how to do．D．In the next few frozen seconds the writer felt the shame and astonishment he had never felt before．( B )What we doEFP Courses provide courses in English language and British culture.

Attachment parents do not “spoil” their children. Spoiling is done when a child is given everything that they want regardless of what they need and regardless of what is practical. Indulgent parents give toys for tantrums(发脾气)，ice cream for breakfast Attachment parents don't give their children everything that they want, they give their children everything that they need. Attachment parents believe that love and comfort are free and necessary. Not sweets or toys.Attachment Parenting is not "afraid of tears" parenting. Our kids cry. The difference is that we understand that tantrums and tears come from emotions and not manipulation. And our children understand this too. They cry and have tantrums sometimes, of course. But they do this because their emotions are so overwhelming that they need to get it out They do not expect to be "rewarded" for their strong negative emotions; they simply expect that we will listen. We pick up our babies when they cry, and we respond to the tears of our older children because we believe firmly that comfort is free, love is free, and that when a child has need for comfort and love, it is our job to provide those things. We are not afraid of tears. We don't avoid them. We hold our children t hrough them and teach them that when they are hurt or frustrated we are here to comfort them and help them work through their emotions.Attachment Parents is not Clingy Parenting. I do not cling to my children. In fact, I'm pretty f ree-range. As soon as they can move they usually move away from me and let me set up a chase as they crawl, run, skip and hop on their merry way to explore the world. Sure, I carry them and hug them and chase them and kiss them and rock than and sleep with them. But this is not me following them everywhere and pulling them back to me. This is me being a home base. The "attachment" comes from their being allowed to attach to us, not from us attaching to than like parental leeches. Attachment Parenting is not Selfish Parenting. It is also not selfless parenting. We are not doing it for us, and we are not doing it to torment ourselves.Attachment parenting is not Helicopter Parenting. I don't hover. I supervise. I follow, I teach, I demonstrate, I explain. I don't slap curious hands away. I show how to do things safely. I let my child do the things that my child wishes to do, first with help and then with supervision and finally with trust. I don't insist that my 23 month old hold my hand when we walk on the sidewalk because I know I can recall him with my voice because he trusts me to allow him to explore and he trustsme to explain when something is dangerous and to help him satisfy his curiosities safely.Most of the negative things that I hear about "attachment parents" are completely off-base and describe something that is entirely unlike Attachment Parenting. Attachment Parenting is child- centric and focuses on the needs of the child. Children need structure, rules, and boundaries. Attachment Parents simply believe that the child and the parent are allies, not adversaries. And that children are taught, not trained.52.According to the author, what should parents do when their kids cry?A.Rewarding kids with toys.B.Trying to stop kids crying.C.Holding them till they stop.D.Providing comfort and love.53.What does “free-range” mean according to the passage?A.Willing to give kids freedom of movement.B.Ready to play games with my kids.C.Curious to watch what games they play.D.Fond of providing a home base.54.Which of the following is NOT attachment parenting?A.Fostering their curiosityB.
