Reading 6B.
3
Addicted to Distraction.
4
David Strayer never texts or talks on a phone when he is driving.
5
Strayer is a cognitive psychologist at the University of Utah who specializes in attention.
6
His research shows that when driving, using a phone can be as dangerous as drinking alcohol.
7
Strayer and other scientists warn against multitasking
8
When we do many things at the same time Strayer says our brain becomes tired easily We make mistakes
9
and lose focus yet multitasking is increasingly common especially on a phone or computer
10
Dr. Gloria mark a digital media researcher has found
11
that people in the United States switch tasks on their computers
12
566 times a day this type of multitasking is especially common among teenagers on average a teenager spends between seven
13
and eleven hours a day in front of a screen doing
14
homework texting watching videos often all at the same time phones tablets
15
and laptops are all useful tools and we may feel more productive when we use them.
16
However, when we spend hours on digital devices, constantly switching between activities, our overall productivity decreases.
17
Why?
18
Many digital activities require high levels of concentration.
19
When we text or email someone, for example, or even play games, we have to focus.
20
When we do this, our brain uses energy.
21
When we multitask, which is hard for the brain to do, we use even more energy.
22
Excessive multitasking reduces our ability to think clearly and creatively, and to remember information.
23
This, in turn, can result in stress.
24
What is the best cure for our overstressed minds?
25
David Strayer says the answer is simple.
26
Spend some time in nature.
27
A natural remedy.
28
Strayer and other scientists are studying nature's effect on our brains and bodies.
29
When we are in natural environments, the prefrontal cortex, the brain's control center, relaxes.
30
Studies show that when people can see trees and grass, they are calmer and do better in school.
31
Indeed, people even relax when they look at photos of nature.
32
Consequently, they do better on different cognitive tasks.
33
Other psychologists are also studying nature therapy.
34
In a study at Chiba University in Japan, 84 subjects went for a 15 -minute walk in seven different forests.
35
The same number of people walked around different city centers.
36
Researchers then took blood from each person.
37
The forest walkers had a 16 % decrease in the stress hormone cortisol all.
38
In addition, they had a 2 % drop in blood pressure and a 4 % drop in heart rate.
39
All did better than the city walkers.
40
Lead researcher Yoshifumi Miyazaki has an explanation for these results.
41
Our bodies relax in pleasant natural surroundings, he says.
42
Humans evolved in that environment, not in places with tall buildings and lots of traffic.
43
Psychologist Stephen Kaplan and his colleagues have done similar research.
44
In one study, people took a 50 -minute walk in a public garden.
45
In a test conducted afterwards, their short -term memory improved.
46
When the same people walked on a city street, it did not.
47
Kaplan says it is the visual details in nature, sunsets, streams, butterflies, that reduce stress and mental fatigue.
48
We enjoy them without having to concentrate on them.
49
This allows our brains to rest and recover from the stresses of modern life.
50
Imagine a therapy that was readily available and could improve your cognitive functioning at zero cost, Kaplan says.
51
It exists.
52
It's called interacting with nature.

本节课学习重点

本节课围绕“分心成瘾”这一主题展开,学习者将通过视频内容练习英语听力理解与口语表达。内容涵盖认知心理学研究、多任务处理的危害及自然对大脑的修复作用,适合提升对学术类话题的理解能力与表达流畅度,同时可结合“英语影子跟读”训练强化口语节奏与语调。

核心词汇与短语

  • multitasking:多任务处理
  • prefrontal cortex:前额叶皮层
  • cortisol:皮质醇(压力激素)
  • cognitive functioning:认知功能
  • mental fatigue:精神疲劳

影子跟读练习技巧

视频语速适中,语调偏向学术讲解,适合“shadow speech”训练。练习时可先逐句播放,模仿发音与停顿,尤其注意长句的断句(如“当我们在数字设备上花费数小时,不断在活动间切换时,我们的整体 productivity 会下降”)。对于包含专业术语的句子,可重复跟读强化记忆,同时感受重音位置(如“cognitive psychologist”中“cognitive”的重读)。

若使用“shadowing site”辅助练习,建议设置0.8倍速先熟悉内容,再逐渐提升至原速。“shadowspeak”训练的关键在于同步性,尽量做到与视频发音、语调一致,无需刻意追求语速。通过反复练习,可有效提升口语流畅度与对复杂句式的掌握能力,同时加深对主题的理解。

什么是跟读法?

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
