34、题。根据题干的关键词“first paragraph”定位到文章的第一段，根据内容surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence ，表达含义是：围绕着一些，就像我们这样的，专注手机的人或者更为糟糕的是在这种令人不舒服的寂静中挣扎，所以选项C正确。9B细节理解题。根据题干的关键词“successful small talk 和Carducci” 定位到文章的第三段Carducci所说的三句话
35、，分别是Small talk is the grease for social communication; Almost every great love story and each big business deal begins with small talk; 最核心的句子是最后一句：The key to successful small talk is learning how to connect with others, not just communicate with them.表达含义是：成功谈话的关键是学会如何和别人产生联系而不仅仅是和他们交流，所以选项B正确。10D细
36、节理解题。根据题干的关键词“coffeeshop study” 定位到文章的第四段第一句末尾，根据两组对比产生的结果：The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience.表达含义是：结果显示这些和服务员闲聊的人都会报告说有更积极的感受和更好的咖啡店的体验，所以选项D正确。11C标题归纳题。根据题干的关键词“best title”得知这是一道标题归纳题，所以这道题只有纵观全文，当然可以借助前面两道题的题干知道文章关键词就是“small talk”，所以锁定B和C项，再结合文章大意得知文章重点描述：小对话的好处而非如何进行小对话，所以选项C正确。
