单选题Questions are based on the following passage.
Using Facebook makes people sadder, at least according to some research. But just what is it about the social network that takes a hit on our mood? A study of the different ways of interacting with the site now offers an answer: Grazing on the content of other people´s idealized lives may make reality painful.
Scientists have long debated Facebook´s impact on users´ in-the-moment mood as well as their deeper satisfaction with life. Some studies have found that the site makes us happier; others, sadder.
One of the problems is that most studies were cross-sectional, taking a snapshot of people at one point of time. But that makes it difficult to separate our use of Facebook from the many other factors known to affect well-being, from overwork to romantic meltdowns. A 2013 study led by
Ethan Kross, a psychologist at the University of Michigan, sidestepped this problem by studying people´s use of Facebook over time, surveying them about their well-being five times per day for 2 weeks. The conclusion was that the more you use Facebook, the sadder you get.
That study generated an enormous amount of attention. But the results offered no clue to what it is about the social network, or how people are using it, that might have this negative effect.
Since then, a collaboration of labs including Kross´s has tried to tease apart the mechanisms.The researchers performed an "intervention," using subjects´ personal Facebook accounts in specific ways. After all, interaction with Facebook consists of a whole set of activities, from browsing photos and "liking" websites to directly interacting with others through messages and comments.
Last week, Kross shared a sneak preview of his team´ s results. Their findings suggest that there is no effect on well-being if one"actively" uses Facebook. When subjects directly interacted with the social network by posting status updates, sharing content, and messaging others, their mood stayed the same over the course of a day. But the negative impact on well-being that Kross discovered in his 2013 study reappeared for individuals who were made to "passively" use the site—just browsing through photographs of other people´ s happy moments, reading people´ s conversations, and not contributing anything.
"Using Facebook is not bad for well-being per se," Kross concluded, but "grazing" its content is. Possible reasons for this were bounced around by the audience of psychologists. For example, one theory holds that people post idealized versions of themselves on Facebook, and comparing those to your own real-world life is toxic if you don´t take part in the online theater.
The word "Grazing" (Para.1) most probably means _____

A．feeding
B．digesting
C．eating
D．scraping

参考答案B

解析:参考译文
一些研究称使用脸谱网会让人变得悲伤。那么社交网络中，究竟是什么在影响我们的情绪?目前，一项采用了多种网络互动方式的研究给出答案：过度关注他人理想化的生活会让你对现实感到痛苦。科学家们在脸谱网如何影响用户的即时情绪上长期争执不下，正如他们在对现实生活中的满意度上所持的不同观点。一些研究发现网络让我们更开心，另外一些则反之。
这其中有个问题。大部分研究都是典型性的，只选取人们某些时刻的即时印象。但是这导致我们很难将社交网络的使用与其他影响我们幸福生活的因素分离开来，这些因素包括劳累过度以及情爱关系中的化学反应。2013年密歇根大学的心理学家伊森·克罗斯在他主导的研究中同样忽略了这个问题。他研究了一段持续时间内人们对脸谱网的使用，每天五次记录他们的生活点滴，这样持续了两周。最后的结论是：你耗在脸谱网上的时间越长，你就会越悲伤。
这项研究引起了人们巨大的关注。但研究结果并没有指出究竟是社交网络的哪一方面，或者人们怎样使用社交网络会带来消极影响。
从那时开始，包括克罗斯实验室在内的几家实验室联合推出一个研究项目，尝试梳理出这一内在原理。研究者对实验进行了“干预”，用特殊方式使用研究对象的脸谱网账号。最终。该项目研究对象在脸谱网上的互动是由一系列的活动组成的，包括浏览照片和“喜欢”的网站以及通过留言和评论来和他人直接互动。
上周，克罗斯提前透露了该团队的研究结果。该结论认为一个人“积极地”使用脸谱网不会影响他的幸福生活。当研究对象通过更新状态、分享评论和聊天这些方式来直接参与社交网络时。他们的情绪状态与一天里其他活动中的情绪状态是一样的。而克罗斯在2013年的研究中发现的对幸福生活产生的负面影响则再一次出现在那些“消极地”使用脸谱网的实验者中，这些人被规定只能浏览记录他人幸福时刻的照片和阅读他人之间的谈话，而不能参与其中。
克罗斯认为。“使用脸谱网本身并不会对幸福生活产生不良影响”．但“吞食”其中的内容却会造成负面影响。心理学家们为此找出了很多可能的原因。例如，其中一种理论认为，人们把自己理想的生活状态放到脸谱网上。并把它与现实生活进行对比，这是很危险的，除非你是在参演网络剧。
解析
含义题。根据题干关键词定位到第一段。最后一句“Grazing他人理想化的生活会让你对现实感到痛苦”，考生可以结合文章主旨判断出Grazing有“过度关注”的意思。digesting“消化；吸收，领悟”可引申为“过度关注”。因此，正确答案是B。
