Example Input: Article: Students often want to practice their English outside class. One of the best ways to practice your English is to speak to a foreigner. You may ask, "Is it okay to try to talk to foreigners I see in the street?" The answer is yes and no, but probably no! If you see a foreigner who looks lost, it is polite to ask him, "May I help you?" But, otherwise, you should probably let them get on with their business. Situations, however, do exist where it is quite all right to talk to foreigners. If a foreigner enters your school, classroom, office, shop or restaurant, for instance, feel free to ask him (for example): -- What is your name? -- Where do you come from? -- What do you think of Beijing? -- How long will you stay in Beijing? There are also situations where it's okay to talk to foreigners in public places. If you see a foreigner alone in a restaurant, bar or coffee shop, it may be appropriate to ask him or her: -- Is this seat free? -- Do you mind if I talk to you in English? You can probably help them if they are new in China and if they are alone, you may be able to make them feel more welcome. After a few such questions, you should know whether this person wants to talk to you or not. If they ask you similar questions, or if they give long, informative answers, you're in luck. If not, then give them their privacy. Talking to strangers is fun if you choose the right time and place.

Example Input: Article: There once was a very wealthy man who had made great achievement. He had more money than he could ever spend, and he was admired and looked up to by his neighbors. Still,he knew that something was missing in his life. He wasn't happy. All his life he had been striving for happiness, but he had never been able to find it. Then one day, he heard about a hidden temple in Nepal that had a special room that contained the secret of happiness. He immediately sold all that he owned and set out to find this hidden temple. After many years of searching and countless hardships he arrived there. He was tired and penniless, but he knew that none of that was important now because he had found the temple. He asked a wise, smiling monk if he could enter the special room. The monk agreed and showed him the stairs leading to the room. He climbed them with legs shaking with expectation and slowly opened the door. He stared into the room with sunlight streaming through the window and saw what he had come so far to find. There hanging on the wall was the secret of happiness. The man gazed at himself in the mirror and laughed. It is time that we all realized that we were the secret of our own happiness. Happiness is a choice that we can make. Don't spend the rest of your life searching the world for happiness then. Just look in the mirror and laugh. Just let the happiness flow from your heart, mind, and soul until it fills your life and the lives of all those around you.
