The Baldrick Manufacturing Company has for several years followed a policy (aimed at decreasing operating costs and improving the efficiency of its distribution system).
A
C aiming at the decreasing of operating costs and improving
我又把A,C混在一起了。先讲讲我的作题思路。刚开始,觉得A对,但又想到并列时,特别是有介词的时候,通常应该aim at.... and at....所以排除A往下看,C意思不太对,但看成aiming at...and improving并列,都做policy的分词修饰结构。比较A和C,选了C。
这样的错误常会发生,请教一下,是不是前后是相同的介词,后一个就可以省略了?。类似的还有带that并列的从句。我做的时候,通常也只找that... and that...有时也会碰到例外。有什么办法,能防止我犯同样的错误呢?是不是把句子意思放在第一位?
