考研英语的疑惑 回答的有耐心我一定加分哦 呵
Outside directors are supposed to serve as helpful,yet less biased,advisers on a firm‘s board.Having made their wealth and their reputations elsewhere,they presumably have enough independence to disagree with the chief executive’s proposals.If the sky,and the share price is falling,outside directors should be able to give advice based on having weathered their own crises.
问题一、Having made their wealth and their reputations elsewhere 是做谁的伴随状语啊?
问题二、based on having weathered their own crises 是怎么理解的啊.
问题三、22.We learn from Paragraph 2 that outside directors are supposed to be .
　[A]generous investors
　　[B]unbiased executives
　　[C]share price forecasters
　　[D]independent advisers
这个题目选B但是我选了D 为什么选B啊?我认为他们是建议者（Outside directors）而不是管理者.当然我知道我错了,就是找不出为什么.

问题一.做Outside directors 的伴随状语
问题二 ,outside directors 能根据所服务的公司暴露的危机情况给出建议.
问题三.对outside directors 的理解
A. Outside directors 是advisers.参见第一句话.
B.根据第一句话,定位advisers 特点helpful, yet less biased,但只是advisers（建议者）,并非executives（执行长）
D.在全世界范围内有一定财富名声后,advisers presumably（可能) have enough independence to disagree with the chief executive’s proposals.
