题目:

2005年10月12日,我国成功发射了“神州”六号载人飞船,这标志着中国人民又迈出了具有历史意义的一步.已知火箭的起飞重量M是箭体(包括搭载的飞行器)的重量m和燃料重量x之和.在不考虑空气阻力的条件下,假设火箭的最大速度y关于x的函数关系式为:y=k[ln(m+x)-ln(
2
m)]+4ln2(其中k≠0)
.当燃料重量为(
e
-1)m
吨(e为自然对数的底数,e≈2.72)时,该火箭的最大速度为4(km/s).
(1)求火箭的最大速度y(km/s)与燃料重量x吨之间的函数关系式y=f(x);
(2)已知该火箭的起飞重量是544吨,是应装载多少吨燃料,才能使该火箭的最大飞行速度达到8km/s,顺利地把飞船发送到预定的轨道?

When difficult people exptures themeelves orally, they generally want at least two things:they’ve been heard and they’ve been understood.As a good communicator should be a good listener, five steps are advocated toward good listening.
The first step is cooperating(合作).How does a difficult person know that you’re listening and understanding?In fact, it’s through the way you look and sound while he is talking. You may help him to fully express his thoughts and feelings. You do this by nodding your head in agreement, making cartain sounds of understandiey.
When the peron begings to repeat what’s been said, is’s a two:turning that you repeat some words he is using, sending a clear signal the you’ve listening carefully and that you think what he is saying is important.
Having heard what he has to say, the next sterp is clarifying.At this point, you start to gather information about whoat is being communicated. Ask same open-ended questions, which will allow you to figure out what intention he is hoping to satisfy.
The fourth step is to summarize(概括)what you’ve heard.This allows you to make sure that both you and the difficult peson the same page. When you do this, two things happen First, if you’ve twisses shinething, he can fill in the (细节).Second you’ve shown that you’re making an effort to understand cometely. This increases possibility of gaining cooperation from him.
Having listened carefully, you’ve now arrived at the point of confirmning with the person that he feels satisfied that this thoughts have been fully voiced. Ask if he feels understood.
Then emough sincere listening, questioning, and remembering are brought together, understanding is usually achieved and a difficult person hecomes less difficult and more cooperative.
