yielding的逻辑主语不是人么？怎么成relaxation了呢？

gonghao

物也可以啊

和produce平行的话，排除BCD

E没有主句去掉

xiaowan

物也可以？deep relaxation yields psychological rewards as relief from stress

不对呀，还是觉得深度放松以后是人取得啊～～～

有啊

举个例子

Progressive relaxation
            yields a variety of benefits

－－－－－－－－－－－－－－－－－－－－－－－－－

再看longman的解释和例句

Our research has only recently begun to yield important results .

These investments should yield a reasonable return .

The tourist industry yielded an estimated $2.25 billion for the state last year.

Each of these oilfields could yield billions of barrels of oil.

以上物都能做yeild的主语啊

当然人是肯定可以得了

举一些longman的例子：

Finally she yielded to temptation and helped herself to a large slice of cake.

he military has promised to yield power.

应该很清楚了

谢谢gonghao！！清楚了，似乎发现，用物作主语的时候yield的意思是产生，人作主语的时候，意思是屈服，获得，含义上还是有不同，明白了～～

再次感谢
