英语四级的听力材料

想要切实提高听力能力，听力材料的`选择十分重要。而应对不同类型的考试材料的选择方式也不尽相同。以下是英语四级听力材料，欢迎阅览!

　　听力原文及解析

Questions 1 and 2 will be based on the following news item.

(1)Multi-tasking is doing two or more things at the same time. Computers are good at multi-tasking. It’s one of the things they’re supposed to do. A lot of people think they are good at multi-tasking. But the sad truth is they are probably not. Our brains on multi-tasking aren’t nearly as good as we think they are. What happens is let’s say you’re working on an activity over here and suddenly now you’re trying to multi-task in another activity. (2)You’re not actually doing both activities at the same time, but, in fact, you’re now diverting your attention from one part of your brain to another part of your brain. That takes time. That takes resources. That takes brain cells. And what happens over here now is that you’re starting a brand new activity. So, in fact, you’re probably slower and not nearly as good at doing both activities at the same time.

【听前预测】由选项可获得关键词multi-tasking, human brains等，由此可以推测该篇新闻应该与大脑同时进行多重任务有关。

do we know about multi-tasking from the news?

【详解】D)。录音一开始就介绍了multi-tasking的概念：“Multi-tasking is doing two or more things at the same time”，因此不难得出选项D为正确答案。

really happens when a man is doing multi-tasking?

【详解】B)。录音中提到，人类大脑其实并不能同时处理两件或多件事情，人们只是将注意力从大脑的一个部分转移到另一个部分，B项含义与此相同，故为正确选项。
