十年前,主人栽下两棵白杨,他俩在同样的沃土上,同样的环境中生长。可是一棵矮小,枝叶微黄;一棵颀长,身体茁壮。尽管主人给矮小的那棵勤浇水、勤施肥,千呵万护,但始终不能使他像另一棵那么健壮。 Ten years ago, the owner planted two aspen trees. They grew on the same fertile soil and in the same environment. But a dwarf, the leaves are slightly yellow; one is long and strong. Even though the owner watered the dwarf plant to diligently fertilize the soil, he could not make him as strong as the other one.
