Researchers at Johns Hopkins University's Applied Physics Laboratory in Laurel,
4
Maryland, have designed a new humanoid, or human-like robot.
5
The name is Robo Sally.
6
The machine can be controlled from a distance and can be used to do work that is dangerous for human beings.

examine them in detail, and do most things that human hands can do.
10
Each finger contains a tiny motor capable of squeezing 20 pounds of pinch force,
11
enough to diffuse a bomb under the direction of an operator.
12
Robo Sally sits on a metal base with wheels that let the robot move around,
13
turn in tight spaces, and climb over small objects.
14
Mike McLaughlin is the main investigator for the Applied Physics Laboratory's prosthetics program.
15
It was a difficult job.
16
Mr. McLaughlin says the robot hand had to have many small
17
motors to have the ability to do what a human hand does.
18
It also needed to have human-like strength.
19
For search and rescue duties,
20
RoboSally will be operated by a person using a wireless machine that is far from the robot.
21

22
The glasses will permit the operator to see the robot's hands.
23
Mr. McLaughlin says this kind of robot could be used in what he calls dull,
24
dirty, or dangerous situations where fine human finger movements are required.
25
Mr. McLaughlin says the technology is not fully ready yet.
26
He predicts that within five years,
27
there will be some very big improvements.

练习技巧
为了提高您的英语发音，有效的练习方法是采用shadowspeak。建议您在观看视频时，模仿说话者的语速和语调。由于视频的语速适中，您可以逐句进行跟读，确保每一个单词都清晰发音。在这段内容中，Robo Sally的介绍需要特别关注技术术语和描述性的形容词，例如“危险”和“控制”。通过不断重复这些句子，您可以纠正自己的发音，为雅思口语练习打下坚实的基础。
此外，您可以根据具体的语境练习不同的发音变化，例如在“手指能力”这类词汇中，注意音节的重音。结合shadow speak，您不仅能提高发音的流利性，还能增强语调和情感的表达，使您在实际交流中更加自信和自然。
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。
