Article: Right now in China, talks on the street have been about the strange weather and it's raising a lot of concerns. A heavy haze has blanketed many cities in the northern and southern parts of the country in part of an unusual weather system that's descended on the nation. The haze stretches over a vast area, from Hebei and Shan-dong Provinces in the north all the way to Zhejiang, Anhui, Jiangsu, Hunan and Fujian provinces in the south. At its worst, the smog is reducing visibility to less than 200 meters and disrupting traffic, both on the ground and in the air. The weather front has also led many to worry about the possible health impacts. Many cities are waking up to another day covered by a dense haze. In Beijing, drivers have to keep their lights on even though it's already past eight o'clock in the morning. Even driving at very slow speeds, the roads can still be very dangerous. In some of the worst hit areas, drivers can't even tell the colors of traffic signals. Authorities have stepped in to close off many highways across the troubled region. In Shandong Province, the highways that are open are backed up for miles. And traffic police have stepped up their patrols. In the region's airports, flights information boards have gone red. A huge number of flights have been delayed or cancelled, nearly three hundred in Beijing alone, leaving thousands of passengers stranded. Some are more frustrated than impatient. Passenger from Jinan airport, Shangdong province, said: "I've been waiting for more than five hours. It's Mother Nature, so there's really nothing we can do." The airport is urging passengers to confirm with their carrier whether their flight will still take off as scheduled. Back on the city streets, people are wearing breathing masks to get free from any ill effects. Fog has cleared a little in Shanghai. But damage has already been done. Shanghai resident said: "I've been wearing the mask, but still, my throat feels sour and itchy. I think it's because of the weather." The weather forecast predicts a cold front is about to sweep across central and eastern China tomorrow. Many are hoping that this will clear away the depressive haze as well as the harm it brings.
Answer: heavy fog
The harm the smog caused didn't include _ .

Article: President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket. "I just miss - I miss being unknown," he said. "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk." His dream, he said, was to "go through Central Park and watch folks passing by ... spend the day watching people - I miss that". Faced with criticism for playing more golf than most previous occupants of the White House, he explained that the sport was simply the best way of getting relaxed. " _ 's the only excuse I have to get outside for four hours," he toldHearstmagazines. Though he said he enjoyed his life in the White House, he felt disillusioned(,) with the some of the ways of Washington, which he has failed to change, such as the "kabuki dance " among political parties before serious policy discussions begin.

Article: Wishing to encourage her young son to make more progress on the piano, a mother took her boy to a Paderewski concert. After they were seated, the mother spotted a friend in the audience and walked down the aisle to greet her. Seizing the opportunity to explore the wonders of the concert hall, the little boy rose and eventually found his way through a door marked "NO ADMITTANCE." When the house lights dimmed and the concert was about to begin, the mother returned to her seat and discovered that the child was missing. Suddenly, the curtains parted and spotlights focused on the impressive Steinway on stage. To her horror, the mother saw her little boy sitting at the keyboard, innocently picking outTwinkle, Twinkle Little Star. At that moment, the great pianist made his entrance, quickly moved to the piano, and whispered in the boy's ear, "Don't quit. Keep playing." Then leaning over, Paderewski reached down with his left hand and began filling in a bass part. Soon his right arm reached around to the other side of the child and he added a melody. Together, the old master and the young beginner transformed a frightening situation into a wonderfully creative experience. The audience was amazed and, as it finished, they cheered. That's the way it is in life. What we can accomplish on our own is hardly noteworthy. We try our best, but the results aren't exactly graceful flowing music. But when we put our trust in the hands of a Greater Power, our life's work can be truly beautiful. Next time you set out to accomplish great feats, listen carefully. You can hear the voice of the Master, whispering in your ear, "Don't quit, and keep playing."
