In 1982, the couple contracted (承包) the land－use rights of the two mountains near their home.They intended to plant fruit trees in the mountains to make a living.Back then, the mountains were deserted with no trees at all.To help the seedlings (树苗) they planted survive in the barren (贫瘠的) land, the couple had to carry water to the mountains on their backs.They also bought whatever seeds were available from a nearby forest farm and spread them every spring, hoping to afforest the mountains.With such an extensive planting method, however, they initially failed to see many seeds take root in the barren soil.But the couple didn't give up. The couple's perseverance finally paid off.They discovered that some tree species were tough enough to survive, including pine and mulberry.Now, more than 50,000 trees of over 20 species cover the land they contracted, following their consistent efforts to sow tree seeds year after year. As the mountains became lush (郁郁葱葱的), Tian and Lu were charged with a new task — patrolling (巡逻) their nearly 67 hectares of forest every day to prevent fires.The patrol even didn't stop on the eve of last year's Chinese Lunar New Year.Instead of watching the CCTV Spring Festival Gala like most Chinese, the couple went to patrol the mountains with the families of their son and daughter.“Many people set off fireworks to mark the arrival of the new year, so the holiday is a time when we have to stay cautious against fire threats，” Tian said. The couple has no plans to quit their work, and they hope their children will follow in their footsteps.“We cherish the mountains and trees as we cherish our own children，” Lu said.“Even as we grow old, they will continue to patrol the woods and watch over the birds.” 语篇解读：本文是一篇记叙文。文章讲述了辽宁省锦州市闾山由一片荒芜变成树木繁茂的鸟类天堂的转变过程。 1．What does the second paragraph mainly talk about?
