to take pictures, or to call friends.

In April, NASA sent three smartphones into space to operate as low-cost satellites.

12
Space agency officials gave names to the three phone sats,
13
as they are called.
14
The names are Alexander, Graham,
15
and Bell, after the inventor of the telephone.
16
All three phone sats looked like small cubes or boxes.
17
Each one was about the size of a drinking cup and weighed a little more than one kilogram.
18
At the heart of each was a Google HTC Nexus One phone.

The microprocessor inside the phone serves as the brain of the mini-satellite.
20
Jim Cockrell works for NASA in California.
21
He says the phone sats were an experiment to find out
22
if a cell phone can serve as the avionics for a satellite.

NASA says the phone sats operated for almost a week.
24
They collected pictures of the Earth and sent messages to ground stations.
25
The agency says smartphones have more than 100 times the computing power of an average satellite.
26

28
think about the work of the phone sats Alexander, Graham and Bell.

练习技巧
在进行影子跟读练习时，请注意以下几点，以便更有效地提高英语发音和口语技巧：
- 慢速模仿： 观看视频时，请先以较慢的速度播放，以便您能够清晰听到每个单词和句子的发音。这将帮助您更好地理解发音规则。
- 停顿重复： 在每个句子后暂停，随后尝试模仿讲者的语调和节奏。通过shadowspeak，您可以快速提高英语口语练习的能力。

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。
