    (5) [A man in Halifax, Canada, wanted to find out if people were thankful for someone holding the door open for them.] The social experiment showed that (7) [99 out of 100 people expressed gratitude.] “I didn’t think we were going to get 99. I don’t know why, but I was pleasantly surprised because it went beyond just ‘thank you’. People got into conversations with us,” said Steve Foran, CEO of Gratitude at Work. “What we know from research is that from grateful people come good things”, he said. “A simple way to induce gratitude in people is opening doors, (6) [and so we went to six places and opened the doors for people.]” For the experiment, Foran’s team went to a shopping centre, a mall, two office buildings, and a coffee shop. (6) [The door was held for 15 to 20 people at a time at each location.] “We did have one that didn’t say thank you. We’re not here to judge them because on any given day, that could be me or you. I suspect out of the 100 people, there were probably a bunch of them having a bad day, (7) [but grateful people make people grateful]”, said Foran.

7. What do we learn from the news report? （我们从这篇新闻中能得出什么结论？）

解析：B。录音中提到，这项社会实验显示，100人中有99人对帮他们扶门的人表示了感谢，占了绝大多数，因此B项符合题意，为正确答案。  

错项排除：录音中虽提到引导人们感恩的方法（A simple way to induce gratitude），但这只是在解释实验的方法，而实验的重点并不在于教育，故排除A项。C项利用录音中的having a bad day设置干扰，但这只是为了说明为什么会有少数人不说谢谢，没有提到大多数人会不会过得不顺心，故排除C项。D项中的ungrateful（不懂感恩）是对别人的臆断，与录音中“我们不会妄加论断”相悖，而且不说谢谢不代表不懂感恩，故排除D项。
