In front of a large mobile gallery on a spectacular day on the Monterey Peninsula during the first round of the AT&T Pebble Beach Pro-Am   Dustin Johnson  and Wayne Gretzky joked  their  way through 18 holes and played superbly as a team on the historically toughest golf course of the three layouts used in this event. Gretzky  who plays fast and clutches a cigar as much as he takes hold of a golf club  got things going by making a birdie for the first time in his golf career on the par-5 first at Spyglass and  getting a stroke because of his handicap   the team  was 2-under-par after one hole.
While Gretzky added another birdie on the par-5 seventh and a clutch par on 16 for birdie   Johnson  was overpowering the seaside and tree-lined course with six birdies en route to a 5-under-par 67. As a team  they shot 65.
 Johnson   who kicked off the year with a win in the Sentry Tournament of Champions in Hawaii  is on the first page of the leaderboard and in position to win for the third time here.
 Johnson  and Gretzky have had a visible bond since  Johnson  started dating Gretzkyâs daughter  Paulina  in 2012. Back then   Johnson  was ranked in the 20s â a freak of talent and power who  while winning a tournament a year  fell short of joining the elite class as  he  struggled with  his  short game and course management and didnât buy in 100% to preparation.
A shift to Butch Harmon as his swing coach paid dividends as  Johnson  has become one of the most feared in the game from 150 yards and in.  Johnson  became a gym rat and severely cut down the times  he  painted the town red at night.  Johnson  also became a father  as  he  and Paulina (they are engaged) are the parents of two young boys â Tatum and River Jones.
And  Johnson  has credited Gretzkyâs guidance and advice for  his  ascension up the world rankings.  Johnson  often picked the NHL iconâs brain and said Gretzkyâs support and belief did wonders for  his  confidence. The two quickly became regular golf partners and talked for hours about how to handle sports fame  pressure and expectations  with Gretzky  in  his  mentoring ways  always stressing to never settle.
As  Johnson  changed  his  habits   his  world ranking changed.  He  was 23rd in the world at the end of 2012  16th at the end of 2013  19th at the end of 2014  eighth at the end of 2015 and third at the end of 2016  when  he  won three of  his  17 PGA Tour titles  including  his  first major championship at the U.S. Open.  He  became No. 1 when  he  won at Riviera Country Club in February of last year and has stayed there for 51 weeks as  he âs piled up four more wins.
 He  has no intentions of leaving.
âThere are a lot of really good players that are playing really well right now  so it's going to be tough for me to keep it â  Johnson  said. âBut if I keep playing like I am and how I should  I'll be there at the end of the year.â

Example Input: "It's important for Russia and China to cultivate a community that respects and understands the cultures of both countries " Pavlova said.
 Pavlova was satisfied with the bulletin boards on which students wrote their feelings about learning Chinese. Chinese motifs such as bamboos were drawn beside texts.
 The students not only learned the Chinese language  but also Chinese politics  economics and cultures as well  Pavlova said.
 The upcoming Year of Chinese Language in Russia would extend the fruits of the reciprocal national theme years (last year was Year of the Russian Language in China)  and would strengthen cultural and educational cooperation between the two countries and thus create favorable circumstances for Russia's young people to learn Chinese language and culture  Pavlova said.
 "Both the teachers and students are eager to take part in the colorful events to be held within the framework of the Year of Chinese Language " she said.
 The school planned to launch a festival of Chinese language and culture in April as part of its contribution to the language year  Pavlova said. Students from 15 schools in Moscow would be invited to the occasion.
 The students were vigorously preparing for the Chinese language contest for elementary and high school students in Moscow as well as the all-Russian Chinese writing contest  while the teachers were scheduled to attend a seminar on Chinese language teaching at Moscow State University  she said.
 Pavlova said she was looking forward to taking her students to various activities  including exhibitions on Chinese language  universities  movies and literature  and a performance of the Beijing People's Art Theater  a famed Chinese drama troupe.
 Pavlova hoped the Year of Chinese Language increased cooperation between schools from both countries  stressing her school and other Russian schools running Chinese courses were keen to establish rapport with Chinese schools  especially those featuring Russian language teaching.

Example Input: Truck driver Tequila Isaacson  was at a rest stop in Snoqualmie Pass  Wash. on Sunday when  she  noticed a family trying to get their child out of a burning pickup truck in the parking lot   she  wrote in a Facebook post.
 Isaacson  searched for a fire extinguisher while someone called 911.  She  was unable to find one until  she  noticed an extinguisher behind the locked door of Red Mountain Coffee.
 She  walked back around the side of the building and saw the fire had spread and was coming from underneath the truck. That is when  she  says  she  returned to  her  own truck and grabbed a metal fence post to break the door.
“I got the fire put out  and everyone safe  before the 911 call was completed ”  Isaacson  wrote.
When first responders arrived   Isaacson  told them that  she  broke the glass door. Instead of responding with thanks  a Washington State Patrol Trooper told her that using a fire extinguisher without permission is theft no matter how good the intentions  KOMO News reported.
“ He  outright stated that unless I was willing to pay for it right then and there   he  would be charging me with burglary ”  Isaacson  told KOMO.
The Washington State Patrol admitted a trooper did speak with  Isaacson  regarding who would be responsible for the damage.
The WSP will reportedly review the way the case was handled and added they are grateful for  Isaacson ’s courageous effort to help the child.
