    Anyone who has ever tried to stop smoking knows how difficult it is to quit. There is no lack of information about how unhealthy smoking is for you- not to mention the unpleasant smell. So why would teens ever begin to smoke?

    {#blank#}1{#/blank#} Research shows that the majority of smokers lit up their first cigarette in their early or mid-teens, precisely at a time when children are beginning to establish their own identity apart from their parents. Smoking can be an act of rebellion(反抗) against parents or authority figures, as well as a way to fit in with others and feel accepted.

    Here are some things that parents can do to help a child stay smoke-free.

    Start talking to your teen about how bad smoking is for him early, well before his teens. Keep talking, too. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#} For example, smoking makes your hair and clothing smell bad, stains the teeth, and reduces your lung power to play sports.

    {#blank#}4{#/blank#} Talk about the addictive power of smoking and tell him while those few cigarettes are his choice, the addiction that occurs shortly afterwards makes him powerless to decide whether or not he wants to light up.

    Work on self-esteem(自尊) and self-confident with your teen. Much of the attraction of smoking is to gain acceptance. {#blank#}5{#/blank#}

    Then the servant knocked in a very guarded manner; the door was opened on the chain; and a voice asked from within, “Is that you, Poole?”

    “It's all right,”said Poole,” Open the door.”

    The hall, when they entered it, was brightly lighted up/The whole of the servants, men and women, stood crowded together like a flock of sheep .At the sight of Mr. Utterson, the housemaid broke into crying hysterically but softly; and the cook, crying out” Bless God! It's Mr. Utterson,” ran forward as if to take him in her arms.” What, what? Are you all here?” said the lawyer impatiently.” Very irregular, very unseemly; your master would be far from pleased.”

    “They're all afraid,” said Poole.

    Blank silence followed, no one protesting; only the maid lifted her voice and now wept loudly.

    Blank silence followed, no one protesting; only the maid lifted her voice and now wept loudly.

    “I told your tongue!” Poole said to her, with a violent accent that proved his own anxiety; and indeed, when the girl had so suddenly raised the note of her mourning, they had all started and turned towards the inner door with faces of dreadful expectation.” And now,” continued the servant, addressing the knife-boy,” reach me a candle, and we'll get this through hands at once.” And then he begged Mr. Utterson to follow him, and led the way to the back garden.

    “Now, sir,” said he, “you come as gently as you can. I want you to hear, and I don't want you to be heard. And see here, sir, if by any chance he was to ask you in, don't go.”

    Mr. Utterson's nerves gave a jerk that nearly threw him from his balance; but he recollected his courage and followed the servant to the foot of the stair. Here Poole signed to him to stand on one side and listen; while he himself, setting down the candle and making a great and obvious call on his determination, went up the steps and knocked with a somewhat uncertain hand on the red baize of the cabinet door.

    “Mr. Utterson, sir, asking to see you,”he called; and even as he did so,once more violently signed to the lawyer to give ear.

    A voice answered from within:” Tell him I cannot see anyone,” it said complainingly.

    “Thank you,sir,” said Poole, with a note of something like triumph（胜利）in his voice; and taking up his candle, he led Mr. Utterson back across the yard and into the great kitchen.

    “Sir,” he said, looking Mr. Utterson in the eyes, “Was that my master's voice?”

    “It seems much changed,” replied the lawyer, very pale, but giving look for look.

    “Changed? Well, yes, I think so,”said the servant, “Have I been twenty years in this man's house, to be deceived about his voice? No, sir; master's killed; he was killed eight days ago, when we heard him cry out upon the name of God; and who's in there instead of him, and why it stays there, is a thing that cries to Heaven, Mr. Utterson!”

    “This is a very strange tale, Poole; this is rather a wild tale, my man,” said Mr. Utterson, biting his finger,” Suppose it were as you suppose, supposing Dr. Jekyll to have been--well, murdered what could cause the murderer to stay ? That won't hold water; it is not reasonable.”

    “Well, Mr. Utterson, you are a hard man to satisfy, but I'll do it yet,” said Poole. “All this last week（you must know）him, or it, whatever it is that lives in that cabinet, has been crying night and day for some sort of medicine . It was sometimes his way--the master's, that is --to write his orders on a sheet of paper and throw it on the stair. We've had nothing else his week back; nothing but papers, and a closed door, and the very meals left there to be taken in secretly when nobody was looking .Well, sir, every day, and twice and there times in the same day, there have been orders and complaints, and I have been sent flying to all the wholesale chemists in town. Every time I brought the stuff back, there would be another paper telling me to return it, because it was not pure. This drug is wanted bitter bad, sir, whatever, for.”

    Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon.

    The British company Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly." It can be moved across continents very quickly because it can be folded and packed," he adds.

    Mr. Stapleton says safety was the company's main concern. He says the designers solved the safety issue by using overlapping rotors to power the vehicle.

    The company is testing a full-size prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams.

    In New Zealand, Martin Aircraft Company is also testing a full-size prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1, 000 meters high and reach a speed of 74 kilometers per hour.

    Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack "is built around safety from the start". In his words, "Reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula One racing car.

    The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute that would be used, if there should be an emergency. "It starts to work at very low altitude and actually saves both the aircraft and the pilot," he adds. Mr. Coker says the Jetpack will be ready for sale soon.

    There is a large percentage of Asian people in the US. They're hard working, respectful but strange sometimes. If you don't understand the culture, you will get some problems with them. Asian people are different from any other cultures if you think you know them, you might want to think again.

    How are they different? When it comes to most Asian culture, respect is everything. You can do anything you want but don't disrespect an Asian man. You will get some real consequences afterward and especially if he is your boss. It's something called face saving in the Asian culture. It's ridiculous sometimes but it's their culture. Sometimes their culture can come in between their relationship at work. Asian people might expect a lot of respect from their co-workers when their co-workers just see them as an equal.

    Americans are very different from Asian people. If you're Asian, you might want to understand the American culture and even adapt to their culture if you work with them. It will be easier for you since you're in their countries. Imagine an American working in China, expecting Chinese co-workers to get along with him when he criticizes them straight out on every single matter in front of everyone. I think they will take him outside and take care of him. It just doesn't work that way with Asian people.

    If you're an American boss giving your Asian employee a review, you will see that they will have a problem with your negative remarks. They will think that you don't like them, disrespectful, and want to get rid of them; when in fact, you're just doing your job. You just encourage them to do their work better. Of course, it's not fair for you as an American boss but just expect that it can be something that is on your Asian employee's mind.

The Big Ben is located in the tower at the eastern end of the Houses of Parliament, Westminster, Greater London. It was designed by Edmund Beckett and Baron Grimthorpe.

The Big Ben is very famous throughout the world, but nobody really knows why it is called Big Ben. There are two hearsays about this. Some people say that it was named after Benjamin Caunt, a boxer, who was called Big Ben. More people believe it was called after Welshman, Sir Benjamin Hall. He was the commissioner(特派员)of the work at the time of its installation in 1859. A story was told that during a debate in the Commons on what to call the bell, Sir Benjamin was about to give his ideas when a MP who sat behind the front bench shouted, "Let's call it Big Ben!" Then this name came into being.

The bell hasn't gone through a smooth road since the beginning of its design. Because there was great disagreement about the design of the clock. It took fifteen years to build. In 1857, the bell was completed and tested on the ground, but a four-foot crack appeared and the bell had to be cast again. Finally, the clock started ticking on 31 May, 1859, and struck its first chime(报时)on 11, July. Then in September, the bell cracked again. It was silent for four years but was eventually turned a quarter of a revolution(旋转). In this way, the crack was not under the striking hammer. Craftsmen made a square above the crack to stop it growing longer and it can still be seen today.

The Big Ben is famous not only for its 13-ton weight, but also for its accuracy(准确性) which is a result of its precise mechanism(机械装置). Even one extra penny's weight on the balance will cause a gain of two fifths of a second in twenty-four hours. Although there have been several problems, the bell is still striking today. Its chimes can be heard all over the world on the B. B. C.
