Article: Hong Kong businesses hit by nearly two months of illegal street occupations breathed a collective sigh of relief on Wednesday. Police finally cleared illegal protesters camped at the main intersection in the Mong Kok district, arresting two student leaders. More than 7,000 officers backed bailiffs (,)clearing occupied sections of Argyle Street and Nathan Road. The two-day operation saw 148 people arrested for various offenses, including contempt of court, resisting arrest, possession of offensive weapons, unlawful gathering and attacking police. The Chief Leader Stephen Hui said 22 officers were injured during the clearances. Police used pepper spray and batons to keep protesters from reclaiming cleared roads and from spreading the illegal occupation to neighboring streets. Six-lane Nathan Road, which goes through the heart of Kowloon, was cleared after nearly five hours. However, comments on the Internet said protesters were looking to reoccupy roads later in the evening. This week's actions mark the first time the authorities have successfully cleared one of the three main protest sites, which sprang up after demonstrators seized key intersections in late September to press for unconstitutional reforms. Contractor Kwan Sui-sum, 55, said he wished the Nathan Road clearance had come earlier, as he has had to pay HK$20,000 ($2,580) after the protesters delayed building reconstruction work. The owner of the Chung Hing Duty Free drug store was cautiously optimistic and eager for his store at the corner of the cleared intersection to get back to business. Sales dropped by 40 percent during the occupation, he said. "I'm not worried about the guess that the protesters will return. I trust in Hong Kong's rule of law and in the police," the man said, who wished to remain unknown as he fears attack from protesters. But five stores at a cleared site owned by jewelry chain Chow Tai Fook were still closed hours later. A company spokesman said the outlets will remain shut while it continues to monitor the situation.

Article: Four Efficient Ways to Improve Your Speech 1. Use More Facial Expression One psychologist feels that our facial expression is responsible more than anything else for the impression others have of us. In fact, more than 50 percent of another's impression, he believes, is influenced by the look on your face. Naturally a smile in which the eyes participate is extremely communicative. An unfriendly look often brings the same thing in return. People tend to mirror your expression, so try to show how you feel about a topic or an idea or the audience through your facial expression. 2. Rid Your Inner Fear It's natural to have some tension or nervousness when you appear before an audience. The way to handle it is to put it to work for you, get into action, as Shakespeare observed, action cures fear. There are only a few known ways to control fear. The first is to admit it, do the thing you fear and it will be the death of fear itself. Another simple aid at the last minute before you begin, is to take a few deep breaths, this will help get the butterflies in formation and also keep your voice under control. In fact, if you're thoroughly prepared, just taking a few deep breaths before you're introduced will give you added confidence and balance. Other known ways to control nervousness and fear are to give yourself an encouraging talk or take some physical exercise. 3. Polish Your Voice Our voice is the main instrument we possess for communicating with people, we're all sound sensitive. So invest in a tape recorder, practise your speech by speaking it into the microphone then listen to it. You can even have others join in the evaluation of your strong points and your weaknesses or faults as well. Remember that Demosthenes and Winston Churchill both used pebbles in their mouths while practising their speaking. Simply reading out loud can also help you improve your voice and develop a personal style. 4. Strengthen Your Memory Psychologists tell us that most individuals don't use above ten percent of their natural capacity for memory, that's comparable to trying to run a car on one cylinder . Why do most people use so little of their power of memory? Because they don't practise the fundamentals of remembering. First and most important, it's necessary to have a burning desire to remember, it's difficult to recall anything without wanting to do so. Step number two is concentration. Henry Ward Beecher once observed, one hour of intense concentration can accomplish more than years of dreaming. The next principle is repetition, we learned many things in school by rote by repetition, when you hear a name for the first time repeat it, spell it, write it down, review it, you'll soon know it by heart.
