When we talk more broadly of body language, rather than good postures, we can actually see the effects it has on relationships right throughout the animal kingdom. In particular, body language is used to express power through expansive（扩张的）postures.
You might know about Amy Cuddy's famous TED Talk and her incredible insights on how posture changes our thoughts. Cuddy and her team study body language, particularly what they call "high-power" and "low-power" poses.
"High-power" poses refer to the act of taking a posture of confidence, which can help you feel more self-confident, even after only two minutes. Typical high-power poses are about opening up. You stretch and expand your body to take up as much space as possible. For example, bosses are doing high-power poses when they lean back in their chairs, put their hands behind their heads, and kick their feet up onto their desks. Meanwhile, people take low-power positions when they're feeling helpless or defeated. They close up arms around themselves, taking up the smallest space.
Some even more recent studies took this even further: A study by researchers from Columbia and Harvard Universities showed that body language symbolizing power can actually affect our decision-making unintentionally. The researchers measured the desire for risk of participants in either expansive, powerful poses or constricted（收缩的）poses. Those in the powerful poses not only felt more powerful and in control, but were 45% more likely to take risky actions.
"This isn't about what your body language is communicating to others; it's about what your body language is communicating to you. Your body language is changing your mind, which changes your behavior, which changes your outcomes," said Cuddy.
So if you want to take advantage of the benefits of these poses to live a healthier and happier life, where should you start?

9. D 细节理解题。根据第三段“'High-power' poses refer to the act of taking a posture of confidence, which can help you feel more self-confident, even after only two minutes.”及第四段“The researchers measured the desire for risk of... but were 45% more likely to take risky actions.”可知，那些摆着扩张式姿势的人通常会感觉更加自信。故选D。
10. C 主旨大意题。通读全文，尤其根据第一段内容可知，文章介绍了身体语言对动物以及人际关系的影响，特别是扩张式姿势可以用来表达权力。由此可知，C选项“肢体语言的惊人力量”能够概括文章主要内容。故选C。
