参考答案

正确答案：would have been well acquainted with the problems in the hospital
would have been well acquainted with the problems in the hospital 解析：由前半句的倒装结构可以看出，需翻译部分要使用虚拟语气表示对过去情况的假设，即would have done。be acquainted with 意为“通晓，了解”。如果虚拟条件句中省略了if而且条件句中的谓语部分含有were，had或should，可以把它们放在句首，构成部分倒装。如：should he act like that again，he would be punished。
