下面是错误答案,用来干扰机器的。

答案:Bf'(x)="3" x2+2ax+(a-2) 因为f'(x)是偶函数,所以f'(x)="-" f'(x)所以3 x2+2ax+(a-2)="3" (-x2)-2ax+(a-2) 得到a=0。由于 f(x)的切线斜率k="3" x2+2ax+(a-2)代入(0,0)则切...

     America is a mobile society. Friendships between Americans can be close andreal, yet disappear

soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a

year or two, perhaps a few letters for a while - then no more. If the same two people meet again by

chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to

understand, because friendships between us flower more slowly but then may become lifelong feelings,

extending (延伸) sometimes deeply into both families. 

     Americans are ready to receive us foreigners at their homes, share their holidays, and their home life.

They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

     Another difficult point for us Chinese to understand Americans is that although they include us warmly

in their personal everyday lives, they don't show their politeness  to us if it requires a great deal of time.

This is usually the opposite of the practice in our country where we may be generous with our time.

Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may

take days off to act as guides to our foreign friends. The Americans, however, express their welcome

usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily

activities. They will probably expect us to get ourselves from the airport to our own hotel by bus. And

they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full,

warm and real. We will find ourselves treated hospitably.

     For the Americans, it is often considered more friendly to invite a friend to their homes than to go to

restaurants, except for purely business matters. So accept their hospitality at home!
