问一道机警语法，谢谢了（明天就考了）

70. In 1994 the white house named Dr. Ruth R. Faden chairperson of the federal advisory committee of experts they assigned to do a report on the history and ethics of the government's radiation experiments on humans in the 1950's and 1960's .

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

没看明白为什么选E，it是怎么来的？

考到的话多半硬着头皮选D了……

多谢大家指教了。

it指的是white house，没错，我想起来了这道题我今天考了。

两个完整的主谓结构句子连着写？

还是独立主格结构可以不加逗号？

谢谢了，我真弱小……

jesuisdesole

独立主格是要用作状语的,这个显然不是,应该是修饰experts的从句省略了THAT

LZ是从那找到SC JJ的啊，居然还总结了70多题,发个连接分享下吧

谢谢谢谢

In 1994 the white house named Dr. Ruth R. Faden chairperson of the federal advisory committee of experts

It assigned the committee to do a report on the history and ethics of the government's radiation experiments on humans in the 1950's and 1960's .

就是这两个句子拼起来。

好吧，全当记了，这句超出了我的语法知识范围……
