【正确答案】 C

【答案解析】[听力原文] W: As you have probably heard in a headline or two by now, it was a sobering day for meat lovers, especially in a country that ranks second in the world for eating the most meat. This new report released today by the World Health Organization found that often-beloved meats, like sausage, bacon, ham, and hot dogs, can cause certain types of cancer. Prior studies had established similar connections, but the WHO is the most prominent health organization to specifically say processed meats can cause cancer. It looked at more than 800 studies around the world. It also found that eating freshly prepared red meat like steak or pork or lamb probably can cause cancer as well. Here to help us sort through this is Jonathan Schoenfeld. He is a professor at Harvard Medical School. He co-wrote a notable paper for The American Journal of Clinical Nutrition in 2012 about the links between diet and cancer. Dr. Schoenfeld, thank you for doing this. The WHO certainly puts the scare into meat eaters all over the country today. How much of this—if I'm someone who has a couple of slices of bacon or a turkey sandwich a few times a week, how worried should I be? M: Sure. So, I think it's important to realize that what the World Health Organization did was, like you said, to look at hundreds of studies and put the evidence from those studies together to show that the consumption of processed red meats was quite possibly associated with an increased risk of a variety of different types of cancer. Now, what these studies did was a look at the overall risk of cancer. And so it's hard to say that any one piece of bacon, for example, or a piece of meat would increase your risk of cancer by a certain amount, but, in total, you know, these studies show that being one of the people who consume the most amounts of meats or processed foods could potentially increase your risk of these cancers. W: So, let's break this down a little bit. When we say processed meats, what are we talking about? M: So, it's actually a definition that encompasses a variety of different ways to add flavor or to help preserve the meats. So the different studies that the World Health Organization looked at might have had a slightly different definition of what processed meats meant. So it could be things like salting, it could be things like adding chemicals to help preserve the food, or to help add flavor to these different foods. W: Is it the process of processing itself that causes the problems or is it the cooking of processed meats? M: You really couldn't say. And the authors of this report admit as much. What they could look at is the total. The act of processing the meat or the consumption of the processed meat was associated with an increased risk of cancer, but the studies don't allow you to actually dissect that further and figure out what exactly it is about processed meats that may lead to the increased risk. What is the major finding in the WHO report? 主旨题。该访谈主要围绕WHO的这一报告展开，开篇就介绍道：“This new report released today by the World Health Organization found that often-beloved meats, like sausage, bacon, ham, and hot dogs, can cause certain types of cancer. Prior studies had established similar connections, but the WHO is the most prominent health organization to specifically say processed meats can cause cancer.”。由此可见，报告主要结论是加工过的肉类会导致癌症，因此答案为C。

【正确答案】 D

【答案解析】[听力原文] How many studies have been used in the WHO report? 数字细节题。问题是WHO报告包含了多少研究，访谈中主持人介绍道：“It looked at more than 800 studies around the world.”。因此答案为D。

【正确答案】 A

【答案解析】[听力原文] What is the relationship between eating processed meat and cancer? 观点题。主持人问：“How much of this—if I'm someone who has a couple of slices of bacon or a turkey sandwich a few times a week, how worried should I be?”Jonathan说“Now, what these studies did was a look at the overall risk of cancer. And so it's hard to say that any one piece of bacon, for example, or a piece of meat would increase your risk of cancer by a certain amount, but, in total, you know, these studies show that being one of the people who consume the most amounts of meats or processed foods could potentially increase your risk of these cancers.”，因此并不是吃一两片肉就会导致癌症，而是吃大量加工过的肉类的人得癌症的机率就会增大。所以正确答案为A。

【正确答案】 B

【答案解析】[听力原文] What is processed meat? 定义题。问题是什么是加工过的肉类。Jonathan说“So it could be things like salting, it could be things like adding chemicals to help preserve the food, or to help add flavor to these different foods.”。因此加工过的肉类是腌制过或加了化学制剂的，所以答案为B。

【正确答案】 D

【答案解析】[听力原文] What causes the problem, processing meat or cooking processed meat? 总结归纳题。访谈最后提到“What they could look at is the total. The act of processing the meat or the consumption of the processed meat was associated with an increased risk of cancer, but the studies don't allow you to actually dissect that further and figure out what exactly it is about processed meats that may lead to the increased risk.”。由此可见processing meat和cooking processed meat不可分割，因此答案为D。
