求英语详细解析

At the international conference ,the famous scientist gave an excellent report _____on his recent experiment.
A.basing B.based C.to be based D.to base
求解这个问题的详细解析！我知道的答案中说base与 report之间是动宾关系，可是我还是不太明白！谢谢！

Answer 1

B
"At the international conference ,the famous scientist gave an excellent report "已经是一完整句子了,后面的"_____on his recent experiment"是用来修饰"report",做定语.
我们可以这样把修饰语和被修饰语转化成这样一个句子:This excellent report was based on his recent experiment.
这样就很明显知道base与 report之间是动宾关系，所以用被动句。
在这个复句中，修饰report的定语从句which is based on his recent experiment，可以省略“which was”。
这种用法很常见的。

Answer 2

在国际会议上，这个著名的科学家做了非常出色的报告，而这个报告是基于他最近的实验的。
base的用法： sth be based on … 某事是基于…的（这个是被动用法） 或者 base sth on …（这个是主动用法了）
给你个例句
This novel is based on the author's real life.

Answer 3

B based on his recent experiment用来修饰report, 是定语从语which is based on his recent experiment的简写, 这种用法很常见的
