Finnish President said Finland-China relations had progressed_______ with fruitful co-operation in new and high-tech fields. A. peacefully                B. highly                      C. quietly                            D. smoothly 答案:D已知函数f(x)=a-blnx(a,b∈R),其图象在x=e处的切线方程为x-ey+e=0.函数g(x)=kx(k>0),h(x)=f(x)x-1.(Ⅰ)求实数a、b的值;(Ⅱ)以函数g(x)图象上一点为圆心,2为半径作圆C,若圆C上存在两个不同的点到原点O的距离为1,求k的取值范围;(Ⅲ)求最大的正整数k,对于任意的p∈(1,+∞),存在实数m、n满足0<m<n<p,使得h(p)=h(m)=g(n).
