1
personal computers have become smaller yet increasingly more powerful today many daily
2
Early activities involve mobile communication and computer access both in and outside the home.
3
For some inventors, the next step is to integrate computers into accessories or into smart clothing, thus creating wearable computers.
4
Martin Kelly reports.
5
The concept of wearable computers is hardly innovative.
6
Early attempts at manufacturing them produced clumsy results.
7
The wearer had to wrap himself in wires
8
or strap a strange -looking device to his forehead and carry a backpack of computer equipment.
9
The technology didn't sell because in today's world, appearance is everything.
10
However, today's wearable computers may provide the solution.
11
Professor Tanya Carter is here to tell us more.
12
Wearable technology is evolving so fast that it has become not only extremely convenient, but a fashion statement too. For example,
13
handheld computers have been miniaturized enough to be strapped to the wrist like a watch not much larger than the average chronometer.
14
Though limited in applications, it is only a matter of time before the watch has full computing capacity.
15
This could eliminate the need to carry a laptop.
16
And rather than attaching all kinds of objects to a jacket, researchers are creating state -of -the -art textiles with electronics built in.
17
One such textile is composed of small patches of fabric into which minuscule computer chips have been embedded.
18
These patches are assembled with Velcro that conducts electricity to create a purse similar in appearance to an ordinary leather purse.
19
This purse provides you with information, such as the latest weather forecast.
20
It can also keep track of your wallet via a minute radio signaling chip attached to the wallet.
21
Sensors integrated into the purse's fabric transmit a message to alert you if the wallet is not inside.
22
This purse even allows you to upload your favorite music onto your music player, which, incidentally, could soon be inside your scarf.
23
I understand that scientists are creating accessories, but there are other innovations in the field of computer -integrated clothing, right?
24
What kind of initiatives are underway to adapt wearable computers for use in fields like health and emergency services?
25
Well, as monitors, wearable computers have many applications.
26
For example, a smart armband registers data about the wearer's physical condition.
27
It can help people lose weight by telling them how many calories they're burning at any given time during exercise.
28
Doctors could also use it to monitor the well -being of the elderly and infants, too.
29
One ingenious adaptation is a shirt made of a special fabric that has the capacity to analyze the wearer's heart rate,
30
respiration, and other key health indicators.
31
For example, it is being used today in medical research to examine the effectiveness of certain new heart treatments.
32
And since it can measure stress levels and body heat,
33
it could be used to monitor firefighters at a blaze or to allow a mother to check on her asthmatic child.
34
Another wearable item
35
that has proved remarkably helpful to runners who want to keep
36
fit is a sensor embedded into the sole of their running shoes.
37
The sensor relays information about the speed
38
and the distance you've covered to your iPod
39
and can change the music track to another song with a faster or slower tempo, thus encouraging you to accelerate your pace or reduce your speed.
40
The sensor is invisible and the earphones are the same as the ones on a regular iPod.
41
So fashion -wise, the wearer would not feel conspicuous.
42
Obviously, as technology advances, so will the wearable computer.
43
Ultimately, it could be a smart assistant that goes wherever we go, registering and analyzing data about us and our environment.
44
Number 1.
45
Why were the first wearable computers unsuccessful?
46
Number two.
47
What development has improved wearable computers?
48
Number three.
49
What is unusual about the new purse?
50
Number 4.
51
How have wearable computers helped medical research?
52
Number 5.
53
Why are wearable computers useful in fitness training?
54
The wearer had to wrap himself in wires
55
or strap a strange -looking device to his forehead and carry a backpack of computer equipment.
56
The technology didn't sell because in today's world, appearance is everything.
57
Wearable technology is evolving so fast that it has become not only extremely convenient, but a fashion statement too.
58
It can also keep track of your wallet via a minute radio signaling chip attached to the wallet.
59
Sensors integrated into the purse's fabric transmit a message to alert you if the wallet is not inside.
60
For example, it is being used today in medical research to examine the effectiveness of certain new heart treatments.
61
Another wearable item
62
that has proved remarkably helpful to runners who want to keep
63
fit is a sensor embedded into the sole of their running shoes.
64
The sensor relays information about the speed and the distance you've covered to your iPod.
65
Thank you.
66
Thank you.

القواعد في هذا الفيديو

أكثر التراكيب التي يستخدمها المتحدث، مع العبارات نفسها من الفيديو:

التركيبفي الفيديو
المضارع التام have/has + اسم المفعول — حدث ماضٍ ما زال له أثر الآنhave become · has become · have been miniaturized
المبني للمجهول be + اسم المفعول — التركيز على ما يحدث لا على من يفعلهhave been miniaturized · is composed · are assembled

نطق يحتاج إلى انتباه

يستخدم المتحدث 5 من الصيغ المختصرة، مثل didn't, you've, they're. انطقها بصيغتها القصيرة كما تسمعها.

  • أصوات “th”: clothing /ˈkloʊðɪŋ/, leather /ˈlɛðɚ/
  • أصوات “sh” و“zh”: shoe /ˈʃu/, unusual /ʌnˈjuːʒ(u)əl/, initiative /ɪˈnɪʃ.ə.tɪv/, innovation /ˌɪn.əˈveɪ.ʃən/, adaptation /ˌæd.æpˈteɪ.ʃən/
  • الكلمات الطويلة — انتبه لموضع النبر: effectiveness /ɪˈfɛk.tɪv.nɪs/, remarkably /ɹɪˈmɑɹkəbli/, accessory /əkˈsɛs.(ə.)ɹi/, unusual /ʌnˈjuːʒ(u)əl/, electricity /ɪˌlɛkˈtɹɪsɪti/

أصوات يجدها متحدثو العربية صعبة:

  • /p/ — ليس /b/: انطقه مع نفخة هواء: purse /pɚs/, chip /t͡ʃɪp/, strap /stɹæp/, helpful /ˈhɛlp.fl̩/, patch /pæt͡ʃ/
  • /v/ — ليس /f/: مع اهتزاز الأوتار الصوتية: convenient /kənˈviː.niənt/, effectiveness /ɪˈfɛk.tɪv.nɪs/, evolve /ɪˈvɑlv/, initiative /ɪˈnɪʃ.ə.tɪv/, innovation /ˌɪn.əˈveɪ.ʃən/
  • تتابع الصوامت — لا تضف حركة بينها: strap /stɹæp/, clothing /ˈkloʊðɪŋ/, helpful /ˈhɛlp.fl̩/, convenient /kənˈviː.niənt/, evolve /ɪˈvɑlv/

كيف تتدرب بهذا الفيديو

  1. استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
  2. ردّد جملة جملة بالسرعة العادية، وكرّر كل جملة حتى يتطابق إيقاعك مع المتحدث.
  3. سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل sensor, wallet, purse.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
