no.28
Rock samples taken from the remains of an asteroid about twice the size of
the 6-nuke-wide asteroid that eradicated the dinosaurs
C."have been dated to be 3.47 million years old and thus are"
E."have been dated at 3.47 billion years old and thus are"
evidence of the earliest known asteroid impact on Earth.
答案是E
请问为什麽不是C?
只有dated to be 和dated at的差别
no.37
In 1994 the white house named Dr RuthR. Faden chairperson of the federal
advisory committee of experts "it 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.
请问it指代什麽呢??
用删去法也觉得这是正解没错
但看不太懂这句句型和句意
有人可以帮忙分析吗???
million thanks!!!!!!!!!
