阅读理解 Whether it's Chinese social media like Sina Weibo, or Western media like Instagram an Facebook, videos can go viral in mere hours. The wide range of viral videos suggests that popular concepts are largely random. After all, what links the recent broom challenge to funny internet cat videos? According to scientists from Stanford University, US, the popularity of a video can be predicted by looking at how certain areas of a person's brain react within the first few seconds of a video. This method has been called neuroforecasting (神经预测) . The team made the finding by recruiting (招募) 36 volunteers to watch a range of videos while being scanned with an FMRI—a machine that can monitor the changes in blood oxygen and flow. Participants were shown 32 different videos and were monitored according to their brain responses in four different areas. The results showed that specific brain activity during the first four seconds of a video could effectively predict a person's thoughts on a video and whether they would keep watching. Using the FMRI results, the Stanford team consistently saw increased activity in the nucleus accumbens (伏核) and decreased activity in the anterior insula (前脑岛) parts of the brain while the participants were watching the most popular of the 32-vidco selection. According to the study, these two brain regions are related to the feeling of expectation we get when we're not certain of something's outcome. Stanford neuroscientist (神经学家) and the study's author Brian Knutson said: "If we examine our subjects' choices to watch the video or even their reported responses to the videos, they don't tell us about the general response online . . . Only brain activity seems to forecast a video's popularity on the internet. " He added, “Future research might also systematically analyze the video content, so content creators can use these findings to make their videos more popular. " In the future, the team aims to use this type of FMRI experiment to understand "whether processes that generate individual choice can tell us something about choices made by large groups of people". According to Knutson, this could apply to shopping trends, charity support and general money-spending. （1） What did scientists from Stanford University find? A . There are differences between viral videos in different cultures. B . People's reported response can predict the popularity of a video. C . There are links between viral videos under different subjects. D . Viewers' initial brain activity can forecast the popularity of a video. （2） What was the brain's response when viewers watched the most popular video? A . All four areas monitored displayed increased activity. B . One area got more active while another became less active. C . Areas related to the feeling of uncertainty got more active. D . The activity of areas related to the feeling of expectation increased. （3） What can we conclude from Brian Knutson's words? A . The participants' choices to watch the videos help them make the finding. B . How long the subjects watched the videos also mattered to their conclusion. C . Our brain activity can show something we ourselves don't realize. D . When the video was beyond the viewers' expectation, it is generally popular. （4） What is the aim of the team's future research? A . Exploring the link between individual and general choices. B . Interviewing content creators how they make videos. C . Discouraging more charity organizations. D . Applying their findings to arresting criminals. 答案： D B C A
