2022年12月英語六級真題聽力第一套（3）
當提及六級聽力時，尤其是英語六級真題聽力，我們不禁會想起那些考驗英語學(xué)習(xí)者聽力理解能力的挑戰(zhàn)。作為英語六級考試的重要組成部分，六級聽力部分不僅要求考生能夠捕捉和識別出基本的語言信息，更需要他們在有限的時間內(nèi)對復(fù)雜的語境進行準確理解，并快速作出反應(yīng)。小編為大家整理了2022年12月英語六級真題聽力第一套Passage 1的內(nèi)容，希望能對您有所幫助！
英文原文
Passage 1
短文1
Stress is often depicted as negative, but research shows that moderate amounts of it can be beneficial for your brain and your body.
壓力通常被描述為負面的，但研究表明適量的壓力對你的大腦和身體都有好處。
First, the benefits for the brain. Studies have shown that short periods of stress can actually bolster cognitive functioning. Researchers discovered that placing rats in a stressful situation for just a few hours doubles the growth of new brain cells. The rats also did better on a memory test later.
首先，對大腦的好處。研究表明，短時間的壓力實際上可以增強認知能力。研究人員發(fā)現(xiàn)，將老鼠置于壓力環(huán)境中僅幾個小時，就會使其新腦細胞的增長加倍。這些老鼠在隨后的記憶測試中表現(xiàn)也更好。
Scientists think the same thing happens in humans, but how does stress improve memory? It's simple: when your brain cells multiply, your memory can improve. Viewed from a biological perspective, this makes sense because animals that are better at remembering dangerous situations can avoid them in the future.
科學(xué)家認為人類身上也會發(fā)生同樣的事情，但壓力是如何改善記憶的呢？很簡單：當你的腦細胞增多時，你的記憶力就會提高。從生物學(xué)的角度來看，這是有道理的，因為能更好地記住危險情況的動物可以在未來避免它們。
If an animal encounters a predator and escapes, for example, it's important to remember where and when that encounter happened. Experts assert that the same principle applies to humans.
例如，如果一只動物遇到捕食者并逃脫了，那么記住這次遭遇發(fā)生的時間和地點就很重要。專家斷言，同樣的原則也適用于人類。
Now let's turn to how stress benefits the body. This may come as a surprise to layman, but experts say that stress can keep you from getting sick.
現(xiàn)在讓我們來看看壓力對身體的好處。這可能會讓外行人感到驚訝，但專家說壓力可以讓你避免生病。
Scientists concede that chronic stress can make you more prone to illness, but research shows that short periods of stress can actually provide some protection against getting sick because it increases your immune functioning.
科學(xué)家承認，長期壓力會讓你更容易生病，但研究表明，短時間的壓力實際上可以提供一些保護，讓你避免生病，因為它可以增強你的免疫功能。
One study shows that rats that experienced brief stress had a surge of immune cell response, which makes the immune system better prepared to fight illness.
一項研究表明，經(jīng)歷過短暫壓力的老鼠的免疫細胞反應(yīng)激增，這使得免疫系統(tǒng)更好地準備對抗疾病。
For humans, there is even evidence that experiencing stress before getting vaccinated could help make vaccines more effective.
對于人類來說，甚至有證據(jù)表明，在接種疫苗之前經(jīng)歷壓力可以使疫苗更有效。
Questions 9 to 11 are based on the passage you have just heard.
問題9到11是基于你剛剛聽到的文章。
Question 9: What did researchers discover about rats placed briefly in a stressful situation?
問題9：研究人員對短暫置于壓力環(huán)境中的老鼠有何發(fā)現(xiàn)？
Question 10: Why do people tend to have clearer memories of dangerous situations they have encountered?
問題10：為什么人們往往對遇到過的危險情況有更清晰的記憶？
Question 11: What do scientists believe chronic stress can do?
問題11：科學(xué)家認為長期壓力能帶來什么影響？
