作文: AA:There is a common misconception that university hospitals are better than community or private hospitals. This notion is unfounded, however: the university hospitals in our region employ 15 percent fewer doctors, have a 20 percent lower success rate in treating patients, make far less overall profit, and pay their medical staff considerably less than do private hospitals. Furthermore, many doctors at university hospitals typically divide their time among teaching, conducting research, and treating patients. From this it seems clear that the quality of care at university hospitals is lower than that at other kinds of hospitals.

数学: 1. m+n是35的倍数,求m的值。(1)m除以5余1;(2)n除以7余3。 2. 有一个环形跑道,跑道宽8米。上下两端是两个半圆,跑道的最内部分半圆直径为64米(就是说,跑道的最外部分直径是64+8+8米),两个半圆中间夹着一个矩形,长100米(就是说跑道的两边是两个百米跑道)。问:跑道的最内边,比最外边的周长小多少。(答案:就是上下两个半圆的周长之差2*pai*(40-32)) |
