Ⅶ.阅读理解
A recent study from a team of South Korean researchers suggests that eating alone often may lead to poor eating habits and poor food choices. Specifically, the study found that men who ate alone more than twice a week had a greater risk of developing high blood pressure, high cholesterol and diabetes.
For children, eating with their families is not only about preventing bad outcomes(结果)—it is also about developing good ones.
In 2014, the Organisation for Economic Cooperation and Development (OECD) looked at data from nearly three quarters of the world's countries. Among its findings was the fact that students who shared a main meal with their families were less likely to skip school. Children who eat a main meal with their families are also less likely to abuse drugs and alcohol(吸毒酗酒)．
In the report, titled “The Importance of Family Dinners(Ⅷ)”， researchers say that “teens who have frequent family dinners are more likely to say their parents know a lot about what's going on in their lives”. They also claim that when teens say they feel closer to their parents, they are less likely to use drugs and alcohol.
Another study from the University of Montreal found that children who ate with their families experienced long term physical and mental health benefits(好处). These children were physically in better shape and drank fewer sugary soft drinks. These children also seemed to have better social skills and they were less aggressive(好斗的)．
Professor Linda Pagani says that mealtimes shared with parents “likely provide young children with first hand social interactions, discussions of social issues(事件) and day to day concerns”. She adds that they may likely help the child have better communication skills with others.
(　　)38.What can be the best title for the text
A．Benefits of eating together B．Advantages of eating alone
C．Ways of developing social skills D．Risks of using drugs and alcohol
(　　)39.Children eating with their families are more likely to________．
A．drink more sugary soft drinks
B．do well in their studies at school
C．be more socially active and aggressive
D．have a closer relationship with their parents
(　　)40.Why is Professor Pagani mentioned in the last paragraph
A．To introduce her.
B．To add a new point.
C．To explain further.
D．To provide background information.
(　　)41.From which is the text probably taken

B．A biology textbook.
C．A cooking instruction.
D．A science magazine.

Ⅶ.[主旨大意] 短文是一篇科普文，主要讲述韩国研究人员对独自用餐者的研究发现，独自用餐者有不良的草草了事的饮食习惯。每周超过两次独自用餐的男子罹患高血压、高胆固醇和糖尿病的风险更高。世界各地各种组织的专家研究发现，和父母一起吃饭的儿童都和父母比较亲近，感觉父母参与他们的生活；这些孩子在身心两方面都健康，有良好的社交能力，不好斗；而且这些孩子不容易逃学、不容易沾染吸毒、酗酒等不良习惯。
38．A　主旨大意题。由文章第二段中的“it is also about developing good ones”可知，文章叙述的是一起用餐的好处。
39．D　细节理解题。由文章第四段最后一句“They also claim that when teens say they feel closer to their parents…”可知他们感觉和父母更亲近。
40．B　细节理解题。通过文章最后一句话“She adds that they may likely help the child have better communication skills with others.”可知，父母经常和孩子一起用餐，很可能会帮助孩子有更好的沟通能力。在整篇文章论述父母和孩子一起用餐的优点上再添加一项。
41．D
