This is the VOA Special English Technology Report.
2
Children can spend hours a day looking at computer screens and other digital devices.
3
Some eye care professionals say all that screen time has led to an increase in what they call computer vision syndrome.
4
Nathan Benilla Warford is an optometrist in Tampa,
5
Florida, with VSP, Vision Service Plan, a big insurance provider.
6
He says,
7
I see a lot more children who are coming into the office either
8
because their parents have noticed that they have headaches or red or watery eyes or discomfort,
9
or because their prescription, their nearsightedness,
10
appears to be increasing at a fast rate, and they're worried.
11
Dr. Benilla Warford says part of the problem is that children may be more likely than adults to ignore early warning signs.
12
Even if their eyes start to feel uncomfortable or they start to get a headache,
13
they're less likely to tell their parents because they don't want to have the game or the computer or whatever taken away.
14
He says another part of the problem is that people blink less often when they use digital devices.
15
The average person who uses a computer
16
or an electronic device blinks about a third as much as we normally do in everyday life.
17
So the front part of the eye gets dry.
18
Eye doctors offer suggestions like following what is known as the 20-20-20 rule.
19
Every 20 minutes, look away 20 feet or more for at least 20 seconds from whatever device you're using.
20
20 feet, that's 6 meters.
21
Other suggestions include putting more distance between you and the device and using good lighting.
22
Of course, you could also spend less time looking at screens.
23
Many experts say children should spend no more than two hours a day using digital devices,
24
with no screen time for children under two.
25
But not all eye doctors have noticed an increase in problems in children.
26
Dr. David Hunter says he has not seen an increase in his practice as a pediatric ophthalmologist at Children's Hospital Boston.
27
He also serves as a spokesman for the American Academy of Ophthalmology.
28
Dr. Hunter thinks calling it a syndrome,
29
as in computer vision syndrome, is a little much.
30
He says the real problem is simple.
31
Spending too much time in one place focusing on one thing.
32
And while this might be tiring to the eyes,
33
he says, there's certainly no evidence that it actually causes any damage to the eyes.

Why practice speaking with this video?

Engaging with the video titled "How Much Screen Time Is Too Much for Children?" provides an excellent opportunity for learners to practice speaking in a real-world context. The topic is relevant as it addresses modern concerns about technology use among children, making it relatable for many English learners. By discussing the effects of screen time, students can practice vocabulary related to health and technology, which are often featured in IELTS speaking practice. Utilizing this video not only enhances listening skills but also encourages the development of conversational abilities by shadowing the speaker. This technique allows learners to imitate intonation, rhythm, and emotion, thereby improving overall speaking proficiency.

Grammar & Expressions in Context

The transcript contains several key structures that can enhance your understanding of English grammar and expressions:

  • Present continuous: The phrase "children can spend hours a day looking at computer screens" uses the present continuous to indicate an ongoing action, which is common when discussing habits or routines.
  • Reported speech: The phrase "Dr. Benilla Warford says" exemplifies the use of reported speech, which is essential in conveying someone's thoughts or statements in English.
  • Conditional structure: The suggestion "If you follow the 20-20-20 rule, you may reduce eye strain" introduces a conditional clause that offers advice, a practical way to learn how to give recommendations effectively.
  • Quantitative expressions: Phrases like "no more than two hours" teach learners how to express limits and quantity, an important aspect in both writing and speaking.
  • Comparative forms: The distinction between children and adults in the phrase "children may be more likely than adults to ignore early warning signs" introduces comparative structures that are useful in making contrasts.

Common Pronunciation Traps

As you practice shadowing the video, be aware of several pronunciation challenges that may arise:

  • Computer vision syndrome: This term contains multiple syllables and can trip up learners, particularly the transition from "computer" to "vision". Focus on breaking it down into parts: "com-pu-ter vi-sion syn-drome."
  • Discomfort: The "dis-" prefix can make this word tricky. Be sure to pronounce it clearly as "dis-com-fort", ensuring you stress the second syllable.
  • Prescriptions: This word can be challenging due to its length. Practice pronouncing it as "pre-scrip-tion", paying special attention to the "scrip" part to avoid slurring.
  • Ophthalmologist: This medical term is often mispronounced. Break it down to "oph-thal-mol-o-gist" to get the pronunciation right.

By focusing on these common traps and employing techniques like shadow speak while watching videos, learners can significantly improve English pronunciation and boost their confidence in spoken communication.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
