爷爷在楼房西侧栽下一株丝瓜秧。一开始,我并不看好它。瓜秧很瘦小,叶子都有些蔫了,看上去半死不活的;它赖以生存的不过是一方长宽不足一尺的小花坛。这里原是一块水泥地,爷爷砌了个花坛,再在里面填了尺许深的泥土。它往何处生根?它向哪里伸展?它到哪里汲取营养?它是否能顶住夏日骄阳的暴晒?……爷爷笑笑,并不回答。 Grandpa planted in the west side of the building a loofah seedlings. At first, I did not like it. Melon seedling is very thin, leaves are a bit rusty, looks half live; but it is only one side of the length and width of a foot of the small flower beds. Here is a piece of concrete, grandfather built a flower bed, and then fill in the depths of the foot deep soil. Where does it take root? Where does it stretch? Where does it take nutrients? Is it able to withstand the summer sun exposure? ... Grandpa smiled and did not answer.
