【答案解析】[听力原文] It is estimated that over 400,000 Americans every year die of smoking related diseases. But kicking the habit is not so easy. A new study finds that smokers who smoke menthol cigarettes could have more trouble trying to quit compared to people who use non-menthol cigarettes. When a study began in 1985, 1,500 smokers had a medical exam and answered the questions about their smoking habits. 63% of the smokers said they preferred menthol cigarettes, and these smokers who preferred menthols were less likely to have quit smoking after 15 years. 69% of the menthol smokers were still smoking when researchers asked again about smoking habits in the year 2000. Among people who had originally preferred non-menthol cigarettes, 54% were still smoking in 2000. The researchers say that both menthol and non-menthol cigarettes are equally dangerous, but menthol cigarettes may actually be harder to quit. [难点] 此题比较容易。

【答案解析】[听力原文] Millions of people around the world use Microsoft office, which comes with Microsoft Word for creating documents, Microsoft Excel spreadsheet, Outlook e-mail and other applications. But now Google is offering some of those same applications with its free, web-based services. Google launched it four years ago. But recently it launched a free spreadsheet program and word processing program that are acquired from another company. Together, they are now called Google Docs & Spreadsheets. Well, neither the word processing or spreadsheet pro- gram is as full-featured as Microsoft's offering, they do provide users with the basic tools they need to write and calculate. Perhaps more important, they also allow you to work from home, office or the road without having you save your files, because they are saved and backed up on Google secure servers. They are also easy to share, facilitating collaboration between people in different parts of the world. Of course, if you are not online, you don't have access. So forget about writing that letter or polishing off that spreadsheet at 37,000 feet. [难点] 本题中的选项极具干扰性，将正确的和干扰性的答案交叉搀合，因此，需要一定的辨别能力和快速筛选能力。

【答案解析】[听力原文] Seems like there is good news for Americans who like to tip one bacchic at happy hour or relax with a glass of wine after work. A recent study by two economists shows drinkers earn more than teetotalers. In fact the data that published in a journal of labor research shows drinkers earn 10%-14% more than people who avoid alcohol altogether. The researchers say this disparity in pay might be explained by the fact drinkers have wider social networks. They argue this enables drinkers to get better jobs and business opportunities, truly increase social capital. But the study has its critics, they point out the researchers founded their work with money from libertarian think tank the Reason Foundation. That group has been fighting in- creased regulation and taxation of alcohol around the country. The authors of the study do point out social drinking has its limits. Having more than 21 servings of alcohol a week they say actually reduces earning potential. One could say all things in moderation. [难点] 此题非常识问题，纯属文章个人见解，因此，需要考生弄清楚说话者的立场。此题也不难，因为答案在文章中明确地出现了。
