1
no guts no glory
2
it's the battle cry of thrill seekers everywhere as they dive off cliffs jump out of planes
3
and ski down avalanche chutes and they do it all just for the rush.
4
But where do these daredevils get the guts to risk their lives over and over again?
5
Some scientists believe there's something about adventure junkies that's different from the rest of us, something they're born with.
6
Could it be that thrill -seeking is literally in their blood?
7
Dr. Julia Farnsworth is here to explore the latest research with us.
8
Dr. Farsworth, welcome to the show.
9
What does the latest research show?
10
Is thrill -seeking really inborn?
11
Thanks, Larry.
12
Yes, there is no evidence that thrill -seeking has a strong genetic component.
13
Researchers have identified at least two distinct genes that they believe are responsible for thrill -seeking behavior.
14
Both of these genes have to do with the brain chemical called dopamine, the brain's pleasure chemical.
15
Dopamine is the substance that makes your brain feel all warm and wonderful inside.
16
What researchers have found is that the brains of thrill -seekers don't produce and absorb enough dopamine.
17
This prompts them to go the extra mile to get a dopamine fix, and that means charging into high -sensation activities,
18
ones that really make palms sweat and heart rates soar.
19
That's fascinating.
20
Are there any figures about how many people may actually have these genes?
21
Researchers believe that at least 30 % of us carry the thrill -seeking genes, but not everyone who has them,
22
they say, feels the need to jump out of airplanes.
23
For some people, intellectual challenges can provide the same satisfaction,
24
and just having the genes doesn't mean that you will necessarily crave new sensations all the time,
25
which leads critics to argue that the researchers genetic theory is a little too simplistic.
26
But whether flirting with danger is nature, nurture, or a combination of both, there's no question that it can quickly become a deadly habit.
27
Hundreds of thrill -seekers a year are killed pursuing a rush.
28
Researchers are also exploring whether
29
or not the same genes may play a role in self -destructive adventure -seeking such as drug and alcohol abuse.
30
So where to from here?
31
What will scientists do with their newfound knowledge?
32
Well, it's still rather unclear.
33
When I asked one researcher if he thought scientists should come up with a cure for self -destructive adventure -seeking,
34
he replied, without thrill -seekers in the world, we wouldn't have any
35
United States of America because Columbus never would have taken off.
36
We never would have put a man on the moon, and we wouldn't have Wall Street.
37
I don't think we want to get into the business of treating core personality traits unless they're really harmful to the person.
38
So, at least for the moment, listeners, it appears that there's no new wonder drug on the way to take away the urge for adventure,
39
nor will a blood test be available anytime soon to find out whether you have the thrill -seeker genes.
40
But there is good news in store for those of you who are couch potatoes.
41
Scientists say they may also have discovered the gene for laziness.
42
What is the main idea of the segment?
43
What is true of thrill -seekers and the levels of dopamine in their brains?
44
According to scientists, how many people carry the genes for thrill -seeking?
45
What is true about people who have the thrill -seeking genes?
46
Why does the speaker mention
47
Columbus, Wall Street, and putting a man on the moon?
48
no guts no glory
49
it's the battle cry of thrill seekers everywhere as they dive off cliffs jump out of planes and ski down avalanche chutes.
50
And they do it all just for the rush.

דקדוק בסרטון הזה

המבנים שהדובר משתמש בהם הכי הרבה, עם המילים המדויקות מהסרטון:

מבנהבסרטון
הווה מושלם (Present perfect) have/has + past participle — פעולה שקרתה בעבר ועדיין יש לה חשיבות או השפעה עכשיוhave identified · have found
משפטי זיקה (Relative clauses) who / which + clause — מידע נוסף על אדם או דברeveryone who has · people who have
סביל (Passive voice) be + past participle — הדגש הוא על מה שקורה, לא על מי שעושה את הפעולהare killed

הגייה ששווה לשים לב אליה

הדובר משתמש ב-14 קיצורים וצורות מקוצרות, כמו don't, they're, wouldn't. אמרו אותם בצורה הקצרה, כפי שאתם שומעים אותם.

  • הצלילים של “sh” ו-“zh”: rush /ɹʌʃ/, sensation /sɛnˈseɪʃən/, satisfaction /sætɪsˈfækʃən/, avalanche /ˈævəlɑːnʃ/, chute /ʃut/
  • מילים ארוכות — שימו לב להטעמה: necessarily /ˌnɛs.əˈsɛɹ.ə.li/, intellectual /ˌɪntəˈlɛkt͡ʃʊəl/, satisfaction /sætɪsˈfækʃən/

צלילים שדוברי עברית מתקשים בהם:

  • /æ/ — פתוח יותר מה-“אֶ” העברית, לא כמו “a” ב-“cup”: habit /ˈhæb.ɪt/, satisfaction /sætɪsˈfækʃən/, absorb /æbˈsɔɹb/, avalanche /ˈævəlɑːnʃ/, fascinate /ˈfæsɪneɪt/
  • /r/ — הלשון לא נוגעת בשום מקום, לא ה-“ר” הגרונית: thrill /θɹɪl/, researcher /ˈɹiˌsɝ.t͡ʃɚ/, rush /ɹʌʃ/, explore /ɪkˈsploɹ/, destructive /dɪˈstɹʌktɪv/
  • עיצור קולי בסוף מילה — /b/, /d/, /g/, /z/, /v/ בלי להפוך אותם לאטומים: destructive /dɪˈstɹʌktɪv/, dive /daɪv/, urge /ɜːd͡ʒ/, absorb /æbˈsɔɹb/, crave /kɹeɪv/

איך לתרגל עם הסרטון הזה

  1. הקשיבו לכל הסרטון פעם אחת בלי לדבר, ורשמו את המילים שאתם לא מכירים.
  2. תרגלו Shadowing משפט אחר משפט במהירות רגילה, וחזרו על כל משפט עד שהקצב שלכם תואם את הדובר.
  3. הקליטו את עצמכם והשוו למקור, תוך תשומת לב למילים כמו gene, scientist, adventure.

מהי טכניקת השאדואינג?

שאדואינג היא טכניקת למידת שפה מבוססת מדע שפותחה במקור להכשרת מתורגמנים מקצועיים ופופולרית על ידי הפוליגלוט ד"ר אלכסנדר ארגואלס. השיטה פשוטה אך עוצמתית: אתה מקשיב לאודיו באנגלית ילידית וחוזר עליו בקול רם מיד — כמו צל העוקב אחרי הדובר עם עיכוב של 1–2 שניות בלבד. בניגוד להאזנה פסיבית או תרגילי דקדוק, שאדואינג מכריח את המוח והשרירים בפה לעבד ולשחזר דפוסי דיבור אמיתיים בו זמנית. מחקרים מראים שזה משפר משמעותית את דיוק ההגייה, האינטונציה, הקצב, הדיבור המחובר, הבנת השמיעה ושטף הדיבור — מה שהופך אותו לאחת השיטות היעילות ביותר להכנה לIELTS Speaking ולתקשורת באנגלית בעולם האמיתי.
