另外一题 看到有人问过了 但我自己没理解
In 1994 the White House named Dr Ruth Daden chairperson of the federal advisory committee of experts _____________a report on the history and ethics of the government's radiation experiments on humans in the 1950s and 1960s.
A they assigned to do
B to be assigned doing
C that was being assigned doing
D assigned for doing
E it assigned to do
我选了B 答案是E 完全不知it 是指代啥?
求各位帮忙解答!!
第二题在E中,其实"of experts"和"it assigned"中间省略额一个"that",完整形式是 ...the federal advisory committee of experts that it assigned to do.. 相当于是定语从句修饰前面的内容,it就是指代the White House。不过这题我之前也错了
