    If you remember the following six ways of information, you'll know how to protect yourself. You'll be much safer at school and in your everyday life.

1)Always notice the environment around you. You shouldn't walk alone out. Make sure where the public phones are. If anything dangerous happens, you can find them quickly.

    Don't use earphones when running in the schoolyard or on the street. You will keep yourself from the outside world and can easily get into trouble.

    When taking a bus, school bags should be carried towards the front of your bodies instead of putting them on your backs. When buses are crowded, it is easy enough for thieves to steal the things in the bag on your back.

    If you are followed by a stranger, cross the street and go in the other direction. Let the stranger know he or she is there. Next, go and get help from others if it is necessary. Don't go home directly. You are safer in the street than you are in your home or in a lift.

    If you have to take a bus to a place far away, try to get to the stop only a few minutes before the buses leave. On buses, don't sit alone. You should sit behind the driver or with friends. Don't sleep.

    Don't play with matches or candles, because it may cause fire. If your house catches fire and you have to escape through smoke, move on your hands and knees with your head 30-60 centimeters above the floor. Please remember there is cleaner and cooler air near the floor during the fire.

阅读《绿》和《囚绿记》节选,完成下列各题。
      (甲)我曾见过北京什刹海拂地的绿杨,脱不了鹅黄的底子,似乎太淡了。我又曾见过杭州虎跑寺旁高峻而深密的“绿壁”,丛叠着无穷的碧草与绿叶的,那又似乎太浓了。其余呢,西湖的波太明了,秦淮河的也太暗了。可爱的,我将什么来比拟你呢?我怎么比拟得出呢?大约潭是很深的,故能蕴蓄着这样奇异的绿;仿佛蔚蓝的天融了一块在里面似的,这才这般的鲜润呀。——那醉人的绿呀!我若能裁你以为带,我将赠给那轻盈的舞女;她必能临风飘举了。我若能挹你以为眼,我将赠给那善歌的盲妹;她必明眸善睐了。我舍不得你;我怎舍得你呢?我用手拍着你,抚摩着你,如同一个十二三岁的小姑娘。我又掬你入口,便是吻着她了。我送你一个名字,我从此叫你“女儿绿”,好么?                       (朱自清,写于1924年)
      (乙)①绿色是多宝贵的啊!它是生命,它是希望,它是慰安,它是快乐。我怀念着绿色,把我的心等焦了。我欢喜看水白,我欢喜看草绿。我疲累于灰暗的都市的天空,和黄漠的平原,我怀念着绿色,如同涸辙的鱼盼等着雨水!我急不暇择的心情即使一枝之绿也视同至宝。当我在这小房中安顿下来,我移徙小台子到圆窗下,让我面朝墙壁和小窗。门虽是常开着,可没人来打扰我,因为在这古城中我是孤独而陌生的。但我并不感到孤独,我忘记了困倦的旅程和以往的许多不快的记忆。我望着这小圆洞,绿叶和我对语。我了解自然无声的语言,正如它了解我的语言一样。
      ②我快活地坐在我的窗前。度过了一个月,两个月,我留恋于这片绿色。我开始了解渡越沙漠者望见绿洲的欢喜,我开始了解航海的冒险家望见海面漂来花草的茎叶的欢喜。人是在自然中生长的,绿是自然的颜色。
      ③我天天望着窗口常春藤的生长。看它怎样伸开柔软的卷须,攀住一根缘引它的绳索,或一茎枯枝;看它怎样舒开折叠着的嫩叶,渐渐变青,渐渐变老。我细细观赏它纤细的脉络、嫩芽,我以揠苗助长的心情,巴不得它长得快,长得茂绿。下雨的时候,我爱它淅沥的声音,婆娑的摆舞。                                                                                                                                                        (陆蠡,写于抗战爆发后的上海“孤岛”
