英語四級的聽力材料

　　想要切實(shí)提高聽力能力，聽力材料的選擇十分重要。而應(yīng)對不同類型的考試材料的選擇方式也不盡相同。以下是英語四級聽力材料，歡迎閱覽!

　　聽力原文及解析

　　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.

　　【聽前預(yù)測】由選項(xiàng)可獲得關(guān)鍵詞multi-tasking, human brains等，由此可以推測該篇新聞應(yīng)該與大腦同時(shí)進(jìn)行多重任務(wù)有關(guān)。

　　1.What do we know about multi-tasking from the news?

　　【詳解】D)。錄音一開始就介紹了multi-tasking的概念：“Multi-tasking is doing two or more things at the same time”，因此不難得出選項(xiàng)D為正確答案。

　　2.What really happens when a man is doing multi-tasking?

　　【詳解】B)。錄音中提到，人類大腦其實(shí)并不能同時(shí)處理兩件或多件事情，人們只是將注意力從大腦的一個(gè)部分轉(zhuǎn)移到另一個(gè)部分，B項(xiàng)含義與此相同，故為正確選項(xiàng)。
