Homework _done___ on time will lead to better grades.
而A new technique ________,the yields as a whole increased by 20 per cent.
A) wording out
B) having worded out
C) having been worded out
D) to have been worded out
是选C,那么这两句里 是怎么区分呢?我非谓语不是很清楚,麻烦替分析一下

1.any 有表示强调任何的意思,如果选A,each本身可以做代词,就应该去掉student.
2．选C,此处one 表示整体.
3．选A,状语前置,表强调
4．Homework _done___ on time 省略了shoule be ;第二句是被动式,而且-ing表示新技术将会被运用.你没打错吧?“word”out?
