英语翻译
这句话怎么翻译?But because hard laughter is difficult to sustain,a good laugh is unlikely to have measurable（可度量的） benefits the way,say,walking or jogging（慢跑） does.这句话怎么翻译?以及后半句的have和句尾的does是什么意义?

Answer 1

但因为大笑很难保持,笑的好不像走路或慢跑那样,可以量化.
have measurable benefit 有可量化的益处
does指代 has,the way...does,是个比较,就像 John jumps not as high as Tom does
