based on就是基于,根据的意思,based on research基于研究等.
base
on放句首是不是一定要固定用based on?
1、base on放在句首时,一般是要用based on的.
如:Based on a true story,the novel is
popular soon.
2、原因:因为base on放句首一般做状语,而句子的主语是做base的宾语的.
即构成固定短语:base + 句子主语
+
on...,意思是“把...(句子的主语)建立在...(on后的宾语)上”.
所以句子主语和base之间一般是被动关系,所以此时必须使用其过去分词based.
3、例句中即:base
the novel on a true story.
