2130201:due to the high pressure of the rate of students and student's physical fitness is in deficiency,the knowledge of PE teacher's is out of date.
想知道的语言点：
1—句尾的the knowledge of PE teacher's is out of date：为什么teacher加了 's

这里的 teacher's 是名词所有格,相当于汉语的“的字结构”.在指代清楚的前提下,后面的名词完全可以省略,如：我的书是关于科技方面的,你的呢?这个“你的”就是省略了上文中的“书”.
英语也是如此.本句中,上文提到了 student's physical fitness,下文为避免重复,就不在提 physical fitness,直接用了 teacher's,其实就是 teacher's physical fitness
