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?
