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.

- 錄下自己的聲音並與原聲對比，特別注意 sensor, wallet, purse 這類單詞。
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
