我选的是A但答案是C求详解
还有一道
_______different kinds of fertilizers, the workers further improved technique.
A.Having been produced
B.Being produced
C.Having produced
D.Producing
我选的是A但答案是C求详解

答案

1.你的答案是对的,应该为A.make use of 是个词组,表示“利用”(make
use of the information 利用信息）
A选项是个定语从句,省略了which 或that(...the use which/that we
made of the infomation.他们没有意识到我们对那个信息的利用.）
2.第二题的答案应该是C.
C 选项在语法上被称为“现在分词的完成形式” 表示“做完...之后”,它相
当一个after...的短语.
例如：1.Having locked the door,she went shopping.(= After locking
the door,she went shopping.锁上门之后,她就去逛商店了)
2.Having washed the clothes,she sat down ,enjoying the music.
(After washing the clothes,she...洗完衣服之后,她坐下来欣赏
音乐 )
3.Having produced different kinds of fertilizers,the workers
futher imporved the technique.
(= After producing different kinds of fertilizers,the
workers futher improved...生产了各种肥料之后,他们又进一步改善
技术)
A 选项 错在 它表示了“被动”的概念 意思为：在被生产了各种肥料之后.
A在语法上称为：现在分词的完成被动式；表示“在被...之后”.
例如：1.Having been used for many years,the bike gives out a strange
noise.（在被使用了多年后,这辆自行车发出吱吱扭扭的怪声音.）
2.Having been bitten twice by the dog,the postman dare not go
to their house.(在被那条狗咬了两次之后,邮递员不敢再去他们
家.）不知这样解释是否明白?
