"People can often make inferences from actions, and the results of these inferences directly affect lives: for example. who will be employed and who will be promoted."Academician Amy Cuddy said in a TV talk show. She also said that "our body language will also affect our perception ( 感知, 看法)of ourselves. When you try to make more authoritative actions,your brain will inadvertently（不经意地）receive signals and actually create an idea that you are more authoritative, so that you have more confidence in yourself".
Therefore, before interviews or important meetings, try not to lean on any object or have a hunched back. Instead, you should try to keep your body relaxed. You can even stand with a relatively authoritative posture (姿势） -of course, you may need to do these things in the bathroom or places where no one could see you.
Body language plays a crucial role in your job interviews, careers, and everyday life. Paying attention to body language could make strong impacts on your behavior,which could help you achieve better results. So, every time you are nervous or feel that you can't do it, stretch your body, smile, and tell yourself "Fake it till you become it!"
4. What does Paragraph 1 mainly tell us
A. What we say in a conversation is not so important.
B. Practicing body language is a short cut to success.
C. We should attach great importance to body language.

故选B。
【分析】国际单位制规定了七个基本物理量。分别为长度、质量、时间、热力学温度、电流、光强度、物质的量。它们的在国际单位制中的单位称为基本单位，而物理量之间的关系式推到出来的物理量的单位叫做导出单位。它们在国际单位制中的单位分别为米、千克、秒、开尔文、安培、坎德拉、摩尔。
2．【答案】D
【知识点】质点；位移与路程；参考系与坐标系；自由落体运动
【解析】【解答】解决本题的关键知道自由落体运动的特点，知道自由落体运动是初速度为零，加速度为g的匀加速直线运动。A．质点是一理想化模型，无论物体质量大小，体积大小。只要在研究的问题中处于次要因素，都可以看做质点，雪花虽很小，能否看成质点，要看对雪花下落研究的问题性质决定，因此不一定可以看成质点，A错误；
B．雪花质量很小，在下落过程中受到重力和空气阻力作用，因此雪花的运动轨迹不一定是直线运动，所以雪花位移的大小不一定等于路程，B错误；
C．在无风环境中，雪花除受重力作用外，还有空气阻力作用，因此雪花不是做自由落体运动，C错误；
