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.

选项 A、Otherwise
B、Moreover
C、Sometimes
D、Together

答案 D

解析副词辨析题。句意为：这些研究共同显示，网上朋友圈大也能指向灰质的增多，而信息处理就发生在这里。本段中提到了不止一项研究，而根据前一句可知，这研究的发现彼此支持，相互认同，得出的结论较为接近，本句也是讲述这些研究发现的共同之处，因此选择together。otherwise“除非”、moreover“此外”和sometimes“有时候”，均可排除。
