Theoretical framework 2

A second theoretical approach emphasizes characteristicsof the marriage market, with the quantity and quality of potential mates the primaryinfluences on mate selection preferences. Individuals who are in anadvantageous position in the marriage market by having a surfeit of availablemates might have little motivation to expand their field of eligibles to those  with dissimilar or otherwise undesirabletraits. In contrast, persons with relatively few marital alternatives, such aseducated black women, might respond not only by remaining unmarried but byenlarging the pool of persons they would consider marrying.

A second theoretical approach 注意上一篇使用了theoreticaltradition. …emphasize characteristics of the..market. (上一篇使用stressthe resources that ….), 后面使用一个状语来形容这个理论的核心要点，with….theprimary influence on mate selection preferences. 此后就是对这个理论的一个expand.Individuals who are in an advantageous position ….. in contrast, persons with relativelyfew marital alternatives,….. .我们再拆开来细看，individualswho are in advantageous position …by having a surfeit of available mates ….mighthave little motivation to expand ….to those with dissimilar or 可以看出是一个很长的句子，并且点明了原因和结果。再看另外处于disadvantageous的persons, with relativelyfew marital alternatives, such as … might respond not only by ….. but by ……

These two theoretical explanations-exchange theory andmarriage market theories- can be used to generate hypothesis linking varioussociodemographic characteristics to mate selection preferences. As argued above,for both men and women socioeconomic resources such as high earnings andeducation might lead to a more restricted preference set. Because exchangetheory suggests that these resources are more important for men’s bargainingpower, their impact on preferences should be stronger for men than for women.

接下来的一段是将两个理论结合在一起说。这篇文章并不同于其他文章，要辩个谁是谁非，它是将两者结合，产生对不同情况的一种分析和解释。Thesetwo theoretical explanations …. Can be used to generate hypothesis linking varioussociodemographic characteristics to ….

用as argued above 衔接，forboth ..and … resources such as … might lead to ….. because exchange theorysuggests that ….. , their impact on ….should be stronger for .. than for ….

如此这样，就产生了一个假设，generatinga hypothesis….
