                                                                                                                                       遥远的炊烟
                                                                                                                                           鲁先圣
        ①只要在乡村生活过,有谁不怀念村庄上空那袅袅升起的炊烟? 袅袅的炊烟在房屋的脊梁上盘旋,在树梢的鸟巢旁飘荡,在胡同的拐角里踱步,最后都凝聚成片片朦胧的烟霞。在那袅袅的炊烟里,有母亲的目光,也有父亲洪钟般的声音。
       ②有多久没有看到过炊烟了?城市里没有炊烟,城市里用的是煤气液化气,即使有了些许的炊烟,也是有害的气体,是不会让人留恋的。况且,城市里的人们,也没有时间留意炊烟,大家都匆匆忙忙,谁会有时间在意稍纵即逝的炊烟?炊烟只属于宁静的乡村,只属于浑厚的黄土地。
        ③只有当停下匆匆步履的时候,只有当心灵归于一份淡雅和安静的时候,那袅袅的炊烟会从久远的记忆中升起来,瞬间就弥漫了你整个的心灵,它像一幅美丽的水墨画,让人有不尽的遐想。
        ④童年的时候,炊烟是娘做好的可口的饭菜。伙伴们成群结队去村外的田野里玩耍,去村头的小河里嬉戏。兴致起来,忘记了时间,忘记了回家。这个时候不知道谁说一声,我家房顶上没有烟了,娘做好饭了。大家立刻都齐刷刷地把目光投向村里,纷纷寻找自己家的房顶。不久前还袅袅升起着的炊烟,都已经渐渐散尽了,娘把饭都做好了。大家自然都收了心,赶快追逐着跑向村里,跑回自己的家里,那里有娘可口的饭菜等着啊。再不回家,娘就要到村口呼唤儿子了。
        ⑤炊烟是汉子们心底的温暖。太阳升起来了,汉子们赶着牲口,拉着牛车,说说笑笑地到村外的田地里劳作。到了中午了,汉子们累了的时候,村里的炊烟也升起来了。这个时候,大家纷纷卸下牲口,在地头坐下,点燃上一支烟,大家的目光都会朝向通往村里的小路。那条小路上,渐渐地,成群结队的妇女,提着饭菜从村里的炊烟里走来了。汉子们的疲劳消失了,那不尽的温暖扑面而来了。
        ⑥炊烟是                   。不论到了天南海北还是在都市庙堂,不论你名满天下还是腰缠万贯,最让你动心的,一定是故乡茅屋上升起的那袅袅炊烟啊!不论你遭受了多么深重的创伤,那随风飘浮的缕缕炊烟,顷刻之间就把你隐藏在了无边的温暖里。
         ⑦当我们忆起年迈的母亲,母亲的身影多半是在炊烟里。有多少回啊?当我们远行回到家里,当我们喊娘的时候,母亲的身影正在炊烟里忙碌。
         ⑧没有风的时候,炊烟就像一棵树,从家里的灶房里生长起来,然后与全村的树聚合成一棵参天大树。有风的时候就不同了,家家的炊烟刚刚冒上房顶,就迅速汇集,变成一片片灰色的云,飘浮到村庄的上空,最后都消失到无边的旷野里。其实,不论是有风的时候还是无风的时候,乡村上空的炊烟都是一幅动人的画卷。可是炊烟与画卷又不同,因为炊烟里还有麦子的香味,更有母亲殷殷的目光。

Big City Bus Driver

    When I was 20, I went to stay with a friend for two weeks in Vancouver. My friend worked during the day, so I decided to go 1 on my own. I knew where I was and where I wanted to go, the Vancouver Aquarium (温哥华水族馆). It sounded 2.

    I've lived in a tiny town all my life, rarely leaving it. Being a “small town girl”, I admit I'm fairly 5about city life. People at home always told me city people were cold and unconcerned about others, so I was afraid to 6to anyone.

    I got on another bus, and then another again. Finally, after hours, I decided to get on ONE bus, and stay on 7 I recognized something. I rode over half an hour. Nothing ever seemed 8 When I became the only passenger on the bus, I began to get 9 I had no cellphone, and didn't even10 my friend's office telephone number.

    As I was about to give up and leave the bus, the driver asked11 I wanted to go. I told him the aquarium, and he laughed, saying his bus wouldn't go anywhere near. I12 back in my seat, really afraid and upset. He asked where I was from, and I told him what had happened and now I just wanted to go back to my friend's place.

    13, the driver pulled the bus over and called me to the front. He gave me detailed 14 as to which buses to take, and how to understand the bus system. He 15 printed the bus tickets I needed from his machine.

    I was shocked. He spent a good twenty minutes 16 me, telling me everything I needed to know, before giving me the tickets. I thanked him repeatedly, and asked him how much I 17 for the tickets. “Nothing. Just get yourself to your friend's home.”

    Thanks to his 18 I was able to make my way back to my friend's house. I don't know what I would have done if that driver had not taken the 19 to help me. What people had told me was not true. City people 20 just like the driver. I never did learn his name, but I'll always remember him.
