Article: Ever since he got into the Hong Kong film industry in 1994 with He's a Woman, She's a Man, Hong Kong director, Peter Chan has been one of the industry's most powerful voices. Later in 1996, another milestone Comrades: Almost a Love Story came into being. Chan's latest film, American Dreams in China is a carefully-calculated film with an eye toward opening the mainland cinema market. American Dreams in China is a film purely for Chinese audiences, but how it plays there remains to be seen. It sends the right messages, but whether that's enough to make it a hit is everyone's guess. Mainland audiences aren't quite that easy to "speak" to. The film began during the period of economic reforms in China in the 1980s. The bookish farm boy Cheng Dongqing (Huang Xiaoming), the ambitious and confident boy Meng Xiaojun (Deng Chao) and the poetic Wang Yang(Tong Dawei), were three friends at university in Beijing and preparing for American visa interviews. Wang was the first to be _ the visa but he gave it up for his western girlfriend, and Cheng was repeatedly denied. Only Meng actually got a study visa. As he was leaving, he told his friends that he wouldn't come back. Several years later, Cheng and Wang built a successful school, New Dream, from the ashes of Cheng's misfortune(his girlfriend got a visa too, and Cheng lost his university teaching job) and Wang's ability to connect with students often through Hollywood movies. In America, Meng suffered a lot. Disappointed, he went home and joined his friends at New Dream. Later, the three friends' relationship became worsened, but finally was improved under the weight of their common goals.

Article: In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja. The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive. "After a while,we figured out that probably the best way is to go for a mass-market way," says Gaze's Sune Alstrup Johansen."where everybody would have this available." Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level. The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements,the technology is then able to easily find where a person's eyes are moving,and then allow the eyes to control a cursor . "Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at,"reads an explanation on the Eye Tribe site. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a _ than a practical way to use one's hands to control a mobile device.Johansen said a replaceable filter would be a cheap,convenient way for most consumers. And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

Article: Remember that goals are dreams with a timetable. Our goals are important for us to create what enriches our life. A very common attitude among people who are successful is that their success lies in their ability to provide themselves goals that are both numerous and exciting. When you think about your future,you are helping to feed a long-term goal of what you want to create. To realize your dreams,you must translate your vision into a series of actions you can take as soon as possible. You should be able to measure these results,to make sure they take you wherever you want. And this step should not be viewed lightly! Indeed,very few people set goals and concrete actions for themselves to achieve. Very few people note what they want to accomplish,and know each day whether they have indeed advanced in the direction of their dreams. Therefore one of the secrets that you can get results from is to write down your goals on paper first. When you give your dreams a form,they become more concrete,and you can refer to them often and easily. Whenever you read the dreams that you note down,you fill your mind with positive and motivational thoughts. Unfortunately,many people stop there. They just simply make wishes, hope and wait. These people do not bring positive difference in their lives,because that sort of behavior is just wishful thinking. Success is not at all a miracle. It depends on clear and realistic targets through serious thoughts:concrete actions and perseverance . Don't forget,your past does not determine your future. Only you now is your potential!
