近几年来，我国开始对国内20个制造业行业中820家企业的采购经理进行月度问卷调查，加工汇总他们对所在行业的采购和供应等问题的判断结果，得到制造业采购经理指数(PMI)。
PMI是一个综合指数，由生产、新订单、主要原材料库存、从业人员、供应商配送时间5个分类指数乘以相应的权数后相加得到。PMI指数反映了当月制造业采购和供应状况相对于上月的变化。各类指数在50%以上，通常反映其对应的某一方面经济扩张；低于50%，通常反映其经济活动衰退。
哪个分类指数对PMI影响最大（）
A．生产
B．新订单
C．主要原材料库存
D．从业人员
参考答案：B
解析：
由表中数据可得，新订单的权数30%为最高，所以新订单指数对PMI的影响最大。
Failure in a relationship, business, career and exam or sudden loss of a close one can make us lose patience and calmness. However, the only person who can help you keep calm is you! You have to find the cause of your problem and then work on it. Here are some tips on how to be calm. Steal some solitary(独自的)moments from your life! Go to a calm and cool place, maybe your local park, a less-visited restaurant or any place that can give you some peaceful moments with yourself. Simply sitting on cool green grass under the limitless sky cam make you feel relaxed. If you can’t find any place, it’s also a good idea to dim (使暗淡)your sitting room light and sit relaxed on your sofa. Talk to the “inner you ”! Open your mind, effortlessly, without a calculating and judging mind! Don’t let yourself be troubled by any belief and thought,. It’s not so simple. But if you just do so, you’ll slowly develop an inner peace. Or course, this doesn’t mean that you’ll stop the daily work linked to thinking! Carry your life as you’ve been, but just sometimes, sit and order your mind to relax. Lean to manage anger! Avoid the things that cause so much stress that they lead to uncontrollable anger. Self-talk can teach a person how to change that inner voice from an aggressive(好斗的) voice to a problem-solving voice. Walking away from a situation until you have better control over your anger will help you avoid creating situations that may grow into dangerous situations. In short, there are many ways to be calm in any situation. Keeping calm is one of the most important things you can do for yourself. Not only will it be good for your health, it can also help you have a better relationship with other people. Title: How to become calm
