B
【答案解析】[听力原文] Good computer skills are desirable in today's digital age, and playing computer games can help children improve those skills—as long as they don't overdo it, scientists warn. The British study involved 600 teenagers over a period of two years and found that those who played computer games less than once a week achieved better grades at school than ones who played them twice a day or more often. The study also found that daily use of social media did not affect school performance. 'It was clear that social media didn't have any impact. I think that's more because social media is part and parcel of every child's life. It's the way they communicate. It's the way they keep in touch with their friends. ' the researchers said. Parents increasingly complain of having difficulty getting their children away from computer games. Some even seek help for their teenagers who they say are addicted to them. The study did not look into addiction, but suggested computer games can cause children to stay up late in the evenings, making them tired and less able to focus at school the next day. Mark Starkey, the longtime owner of the Heart of Gaming computer game outlet in London, said there is also the difference between older games and the new ones. 'The ability to make games a lot more bigger, a lot more detailed, a lot more intricate is here now. It is going to hold their attention longer. It is going to hold it a lot longer, because there is always wanting to progress through the story line—Oh my god, I have to see what happens next, etc. Whereas, again, the old games challenge more your hand-eye coordination, your speed, your timing, your reactions, rather than perhaps your imagination. ' The games industry has long claimed there is no proven link between games and addiction. But the new study says additional research is needed to establish the effect of prolific computer game-playing on performance at school. What does the British study mentioned in the lecture find out? 听力原文中在描述这项英国的研究时提到实验发现玩电脑游戏的频率少于一周一次的学生要比频率大于等于一天两次的学生的学习成绩好，故选项B为答案，同时排除选项D。而后又提到该研究还发现日常使用社交媒体并没有什么影响，故排除选项A。听力原文后面又提到该研究并未调查上瘾情况，因此排除选项C。
【正确答案】
B
【答案解析】[听力原文] What is the difference between the old games and the new ones, according to Mark Starkey? 题干中的Mark Starkey为答题关键词，本题问Mark Starkey认为新旧游戏的区别在哪里?听力原文中提到现在的新游戏更大、更为精细，而且变得越来越复杂。它会长时间吸引玩家们的注意力。而老游戏更多的是挑战你的手眼协调能力、你的速度、你对时机的绝佳把握、你的反应，而非你的想象。由此可知，只有选项B符合听力原文内容，为答案。
