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.
