當(dāng)提及六級(jí)聽力時(shí)，尤其是英語六級(jí)真題聽力，我們不禁會(huì)想起那些考驗(yàn)英語學(xué)習(xí)者聽力理解能力的挑戰(zhàn)。作為英語六級(jí)考試的重要組成部分，六級(jí)聽力部分不僅要求考生能夠捕捉和識(shí)別出基本的語言信息，更需要他們?cè)谟邢薜臅r(shí)間內(nèi)對(duì)復(fù)雜的語境進(jìn)行準(zhǔn)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(jí)真題聽力第一套Passage 1的內(nèi)容，希望能對(duì)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(fù)面的，但研究表明適量的壓力對(duì)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(duì)大腦的好處。研究表明，短時(shí)間的壓力實(shí)際上可以增強(qiáng)認(rèn)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(gè)小時(shí)，就會(huì)使其新腦細(xì)胞的增長(zhǎng)加倍。這些老鼠在隨后的記憶測(cè)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(rèn)為人類身上也會(huì)發(fā)生同樣的事情，但壓力是如何改善記憶的呢？很簡(jiǎn)單：當(dāng)你的腦細(xì)胞增多時(shí)，你的記憶力就會(huì)提高。從生物學(xué)的角度來看，這是有道理的，因?yàn)槟芨玫赜涀∥ｋU(xiǎn)情況的動(dòng)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(dòng)物遇到捕食者并逃脫了，那么記住這次遭遇發(fā)生的時(shí)間和地點(diǎn)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(duì)身體的好處。這可能會(huì)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(rèn)，長(zhǎng)期壓力會(huì)讓你更容易生病，但研究表明，短時(shí)間的壓力實(shí)際上可以提供一些保護(hù)，讓你避免生病，因?yàn)樗梢栽鰪?qiáng)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(xiàng)研究表明，經(jīng)歷過短暫壓力的老鼠的免疫細(xì)胞反應(yīng)激增，這使得免疫系統(tǒng)更好地準(zhǔn)備對(duì)抗疾病。

For humans, there is even evidence that experiencing stress before getting vaccinated could help make vaccines more effective.

對(duì)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(duì)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(duì)遇到過的危險(xiǎn)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(rèn)為長(zhǎng)期壓力能帶來什么影響？
