21307—（张）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high pressure of the rate of students and student's physical fitness is in deficiency,the knowledge of PE teacher's is out of date,so it affected PE teaching and student's physical fitness.3752
想问：
1—the high pressure of the rate of students:怎么翻译.又是两个of的
2—is in deficiency：这种be加介词短语 表示一种状态吧?
补充：out of date：过时的,陈旧的.
