1，英语（背Youth）;
Youth is not a time of life, it is a state of mind. It is not a matter of rosy cheeks, red lips and supple knees, it is a matter of the will, a quality of imagination, a vigor of emotions, it is the fressness of deep springs of life.
Youth means the tempramention prodominent of courage over timidity, of appitite for the adventure over the love of ease.This often exists in men in 60 years old than boys in 20 years old. Nobody grows old merely by a number of years, we only grow old by deserting our ideals.
...
Whether 60 or 16, there ...

PS：I know I need to exercise more. Be better tmorrow.

求极值和求最值：求极值通过求y',然后判定y’的符号，y''可以作为辅助；求最值通过求驻点和不可导点以及端点的值来判定，当只有一个驻点时，极值即为最值，在实际问题中，求出驻点不需判定是否为极值，此驻点即为最值点。
绘制函数的图像：五个步骤，求y'，y''；求y'，y''为0的值以及y,y',y''的断点；列出表格；判定渐近线；补充一些点，精确图形。
PS：如果不能静下心来做数学题，那就没有意义了。

1，Youth is not a time of life, but a state of mind. It is not a matter of rosy cheeks, red lips, supple knees, it is a matter of the will, a quanlity of imagination, a vigor of emotions. It is the freshness of the deep springs of life.
Youth means a temperamental prodominance of courage over timidity, of appitite for adventure over love of ease. This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of years, we grow old by deserting our ideals.
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.
Whether 60 or 16, there's in every human being's heart the lure pf wonders, the unfailing appitite of what's next and the joys of the game of living.In the centre of your heart and my heart, there is a wireless station. So long as it can receives the messages of beauty, hope, courage and power from the man and from the infinite, so long as you are young.
When the aerials are down and the spirits are covered with the snows of cynicism and the ice of pessimism, then you've grown old, even at 20.But as long as the aerials are up, to catch the waves f optimism, there is hope you may die young at 80.
the的使用很不熟练，还有介词的使用，appetite拼写错误,等等

曲率的计算，弧微分，曲率圆，曲率半径，不难，主要考察求导的计算
不定积分，定义，基本性质，根据求导反推过来的基本公式牢记

驻点和极值没有直接关系！只有一个驻点，肯定就是极值，哥们好好看看驻点，极值的定义吧，不要盲目做题，先搞懂定义
