        White meat, such as chicken, may raise blood cholesterol levels as much as red meat does. (1) [This finding surprised researchers,] who admitted they didn’t expect that eating white meat would lead to higher blood cholesterol levels. In the study, researchers looked at 113 healthy people. The participants ate three different diets. These were a red meat diet, which is primarily beef, a white meat diet, which is mostly chicken and turkey, and a vegetarian protein diet. Each diet period was four weeks. Between the diet periods, participants had a break, during which they ate their regular foods. In addition, participants had blood tests at the start and finish of each new diet. The results showed that white and red meat diets had the same effects on blood cholesterol levels. Further, both diets increased blood cholesterol levels compared with the diet built on vegetarian protein sources. (2) [The team acknowledged that it is possible that white meat is better for our health than red meat despite their findings.] This is because other effects of red meat consumption could contribute to heart disease independent of cholesterol. Their main recommendations are that people eat less of both kinds of meat and more vegetarian protein.

1. What do we learn from the news report about the study?（关于这项研究，我们能从新闻中了解到什么？）

解析：D。录音开头提到，白肉和红肉一样能引起血液中的胆固醇水平升高，这一发现让研究人员很惊讶（This finding surprised researchers）。D项与此内容相符，其中的finding和researchers原词复现，came as a surprise对应录音中的surprised，故为正确答案。

错项排除：录音中没有提到胆固醇对人体健康的影响，故排除A项。录音中提到，113名参与者都是身体健康的人，没有提到他们血液中的胆固醇水平都很高，故排除B项。该项研究发现，与素食蛋白饮食相比，红肉和白肉都会提高受试者血液中的胆固醇水平，因此建议人们多吃素食蛋白，C项与此相悖，故排除。
