    Lisa Pina never thought she would need the fire safety training she received during her apprenticeship(学徒期)as a union painter and dry waller(筑墙工). On Friday morning, she was thanking God she had it.

    On Thursday night, while Pina was babysitting her granddaughter, nephew and two nieces in her sister's apartment, she smelled smoke and realized the apartment building was on fire. When her 4-year-old granddaughter Ilean Garcia began saying, “We're going to die, ”she knew she had to act.Pina,39, first sealed the door, and then told all four children to get on the floor. After calling 911, she told the children to start singing and promised them all treats as soon as they reached safety. “I said, ‘OK, we're going to lie down and we're all going to play a game,'” Pina said. “We all started singing our ABCs and 123s.I was just trying to make it fun.” Pina patiently waited, and a few minutes later, Riverside County sheriff's deputies (治安官的助手) arrived. Pina, Ilean,8yearold Gabriel Parga,5-year-old Aubreyana Parga and 4-year-old Meriyah Parga were all trapped on the second floor as flames filled the first story.  Pina did the only thing she could. She opened the window and dropped the children, one-by-one, into the arms of the sheriff's deputies about 15 to 20 feet below. “I just needed to keep the kids calm so they wouldn't be afraid,”Pina said.“I was deathly afraid inside,but I couldn't let them know that.”Not long after dropping the children out of the window, firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke, but nobody was seriously injured.

                                                                                                              游东坡 

                                                                                                         【南宋】陆游
         十九日早,游东坡。自州门而东,冈垄高下,至东坡则地势平旷开豁。东起一垄颇高,有屋三间。一龟头曰“居士亭”,亭下面南一堂颇雄,四壁皆画雪。堂中有苏公像乌帽紫裘横按筇杖是为雪堂。堂东大柳,传以为公手植。正南有桥,榜曰“小桥”,以“莫忘小桥流水”之句得名。其下初无渠涧,遇雨则有涓流耳。旧止片石布其上,近辄增广为木桥,覆以一屋,颇败人意。东一井曰“暗井”,取苏公诗中“走报暗井出”之句。泉寒熨齿,但不甚甘。又有“四望亭”,正与雪堂相直。在高阜上,览观江山,为一郡之最。
                                                                                                                                                                                                                (节选自《入蜀记》)
        【注释】东坡:苏轼被贬黄州时,开辟了一处荒地,名为东坡。龟头:形容垄头昂起,上建小亭,有如龟头。筇杖:竹枝。雪堂:苏轼在东坡建筇室时,天下大雪,于是在堂壁绘雪,题堂名为“雪堂”。
