硬边

But it is intuition which makes me feel the uncanny glassiness of the lake this afternoon, the sulkiness of the mountains, the vividness of near green in thunder-sun, the young man in bright blue trousers lightly tossing the grass form the scythe, the elderly man in a boater stiffly shoving his scythe-strokes, both of them sweating in the silence of the intense light.

但是，是直觉要我感受湖泊在今天下午的神奇般明净，群山的阴沉，有太阳的雷声中呈现出的主动的，近乎于绿色的颜色，那个穿着天蓝色裤子的年轻人用长镰轻松地割着草，还有那个戴着硬边草帽的年长者笨拙地挥动着长镰，在强烈的光线和寂静中，两个人都在流汗。

And I was so pleasantly musing over the two men mowing: the young one, with long legs in bright blue cotton trousers, and with bare black head, swinging so lightly downhill, and the other, in black trousers, rather stout in front , and wearing a new straw hat of the boater variety, coming rather stiffly after, crunching the end of his stroke with a certain violent effort.

可我刚刚还在愉快地望着两个割草人若有所思：年轻的一位生着一双长腿，穿着天蓝色的棉布裤子，黑黑的头发上没戴帽子，在山脚下轻松地来回摇摆着长镰；另一位穿着黑裤子，前面肚子挺壮实，戴着一顶新的硬边草帽，呆板板地走在后面，颇费力气地用镰刀尖嘎吱嘎吱地割着草。

I want to look at the mowers, and wonder why fatness, elderliness, and black trousers should inevitably wear a new straw hat of the boater variety, move in stiff jerks, shove the end of the scythe-strokes with a certain violence, and win my hearty disapproval, as contrasted with young long thinness, bright blue cotton trousers, a bare black head, and a pretty lifting movement at the end of the scythe-stroke.

我想看割草人，想知道为什么这个胖子、长者和黑裤子竟非要戴一顶硬边的新草帽，而且动作不灵活，颇废气力地用长镰的刀尖割草；而年轻人又高又瘦，身着天蓝色棉布裤子，一头黑发，不戴草帽，用长镰割草时，刀尖优美地向上一提，使我在对照之下对年长者产生由衷的不赞同。
