四月中旬,我从西安北上毛乌素大沙漠南端的“三边”:靖边、安边、定边。那里的沙尘暴与西安相比,确实不可同日而语。风沙一来,天空中蹿起黄黑色的沙云,遮天蔽日,不时向四周无声地伸展它那沙魔的四肢。街面上,店铺关了门,包了头巾连眼睛也不要的女人,和把塑料袋子套在头脸上的怪模样男人,在蛮横的沙尘暴中,无不鼠窜。汽车开着昏黄的灯,在路上蹒跚。每当这时,谁的心里不在呼唤绿色的植物? In mid-April, I went north from Xi’an to the “three sides” of the southernmost Muauin Desert: Jingbian, Anbian and Dingbian. Sandstorms there are really different from those in Xi’an. When the wind and sand come, the yellow and black sand clouds rise in the sky, covering the sun, silently stretching its sand-demon limbs all around. On the street, the shop closed the door, wrapped the woman in a headscarf with no eyes, and a strange man with a plastic bag over her head and face. The car was lit with dim lights and staggered on the road. Whenever this time, who’s heart is not calling for green plants?
