B

Binge­watching (追剧)your favorite TV series is bad for your brain.Dr.Randall Wright，based in Texas，said the need to watch episode (集)after episode has a similar influence on the brain to gambling (赌博)．What's more，it often leads to social loneliness，snacking on junk food and a shortage of exercise and sleep，which，over time，is bad for the brain.

When you let auto play start the next episode，you can find out what happens next and your brain receives good feedback，Dr.Wright wrote in an article.This right­away satisfaction is similar to gambling where even after a win，you are not satisfied and want to continue playing.With binge­watching，you are not satisfied with stopping after episode five and want to continue watching.This cycle coupled with the snacking and the long time sitting can lead to unhealthy changes in your brain and body over time.

Dr.Wright said，“Binge­watching itself is not bad.It becomes problematic when you are watching a third，fourth or fifth episode instead of doing healthy activities.” But he said it is possible to avoid the bad influence of binge­watching with four tips，including staying away from salty，fatty，calorific foods，exercising before a binge­watching，setting an alarm for sleep and balancing TV viewing with socializing.

If you add these tips to your binge­watching practice，you can create lasting healthy habits and still enjoy the now­and­then binge­watching time without hurting your brain.

C．TV series.   D．Brain.

B　[词义猜测题。前文说到“Dr.Randall Wright，based in Texas，said the need to watch episode after episode has a similar influence on the brain to gambling.What's more，it often leads to social loneliness”可知，德克萨斯州的兰德尔·赖特博士说，一集接一集地看电视对大脑的影响类似于赌博。后文紧接着说“更糟糕的是，它经常导致社交孤单感等不良影响”，所以it指的是追剧。故选B项。]

6．In what way is binge­watching like gambling?

A．The long time sitting.

B．The changes of feeling.

C．The snacking on junk food.

D．The immediate satisfaction.

D　[细节理解题。由第二段“This right­away satisfaction is similar to gambling where even after a win，you are not satisfied and want to continue playing.”可知，这种即时的满足感类似于赌博，即使赢了，你也不满意，想要继续玩下去。由此可知，追剧获得的即刻满足感类似于赌博获得的快感。故选D项。]

7．What is Paragraph 3 mainly about?

A．The tips on how to develop a healthy lifestyle.

B．The reasons why binge­watching is problematic.

C．The ways to keep away from binge­watching.

D．Do's and don'ts of binge­watching.

D　[主旨大意题。由第三段“But he said it is possible to avoid the bad influence of binge­watching with four tips”可知，本段主要讲述了赖特博士就如何避免追剧的不良影响提出的建议，与D选项“Do's and don'ts of binge­watching.”吻合。故选D项。]

8．What may be the best title of the passage?

A．Ill Health: The Result of Addiction

B．Healthy Habits: A Must of A Better Life

C．Binge­watching: A Killer of Your Brain

D．TV­Viewing: Gradual Harm on Your Health

C　[标题判断题。文章第一段“Binge­watching your favorite TV series is bad for your brain.”可知，追你最喜欢的电视连续剧对你的大脑有害，即追剧有害大脑，后文阐述了追剧对大脑造成的危害及如何避免追剧带来的不良影响。由此可知，Binge­watching: A Killer of Your Brain(追剧：大脑的一个杀手)适合做本文最佳标题。故选C项。]
