下面这段话最后一句中的act是个什么意思?
in order to understand the nature of the ecologist "s investigation ,we may think of the density-dependent effects on growth parameters as the "signal " ecologists are trying to isolate and interpret ,one that tends to make the population increase from relatively low values or decrease from relatively high ones ,while the desity -independent effects act to produce "noise" in the population dynamics.
act to是一个词组,不知道你百度了没有?连起来意思是(会采取措施)做某事
再问: 恩,是的,我百度了!是有act to do 采取行动做某事。 我想的是不是还i有其他的用法。谢谢你!
