Online social networks are massively influential, yet we understand very little about the impact they have on our brains. Recently, scientists have found a direct【C1】______ between the number of Facebook friends a person has and the size of【C2】______ brain regions. The study also shows the more Facebook friends a person has, the more real-world friends he is【C3】______to have.
Facebook users who have a【C4】______ of friends also tend to have smaller circles of friends in the real-world and,【C5】______ those who have thousands of friends on Facebook are likely to have larger circles offline, according to the study. The findings support the【C6】______ that most Facebook users use the site to【C7】______ their existing, real-life social relationships, maintaining or reinforcing these friendships,【C8】______creating a network of entirely new,【C9】______friends.
The researchers scanned the brains of 125 university-aged Facebook users,【C10】______these scans to the size of their friend networks online and the real-world. Those with larger Facebook networks had larger amounts of grey matter in several regions of the brain. One of these regions, the amygdala, is【C11】______with processing memory and emotional responses. Pairing this【C12】______ another recent study, the researchers show increased volume grey matter in the amygdala【C13】______a larger network of real-world friends.【C14】______ these studies show a large network of online friends also point to an increased volume of grey matter—【C15】______ information processing occurs. In addition to brain scans, the participants were asked questions【C16】______to compare the size of their online networks to the size of their real-world networks.
The study【C17】______ the correlation between the number of friends online【C18】______ offline. Still, it is not possible from the【C19】______to say whether having more Facebook friends makes the regions of the brain larger【C20】______ whether some people are " hardwired" to have more friends.
【C13】
选项
A、indicates
B、causes
C、reveals
D、ensures
答案
A
解析
动词辨析题。句意同上。根据本段前两句可知,朋友圈大的人,脑部某些区域的灰质较多,而特别提到的区域就是杏仁体。由此可知,杏仁体的厌质较大可以表明现实世界的朋友圈就越大,故indicate“表明”符合文意。两者之间不是因果关系,因此排除cause“引起”;reveal“揭示”用于难以发现的秘密等,不符合文意;灰质的增加不可能确保人的朋友圈扩大,故ensure也不合文意。
