Student or Learner
I have a few questions that I need you to help me.
1/ Which word or phrase (in brackets) here needs correcting? And please explain why.
(Until) recently, I (have trusted) Jim (with) the (most difficult) jobs of the company.
2/ The river is polluted ... aluminum.
In the gap, should I use "by" or "with". What's the difference between using polluted by and polluted with?
Thank you in advance :)
Thank Luschen for your help
1/ The first question still need an answer.
2/ Chemical plants is somehow sounds like an object, not "who" Anyway, I still want to understand more clearly about the difference between using them.
more hint on the second question.
Here, "by" will be the person who did it and "with" will be the object used by the person to pollute it.
e.g 1-The river was polluted by Aluminum.(Aluminum here is considered a name of somebody.
2-The river was polluted with aluminum.(aluminum here is considered as a material or chemical waste.
The meaning of "The river was polluted by aluminum" would be quite obvious to a native speaker, and it would mean the same as "with aluminium" - unless the speaker wanted to make a distinction between who did it and what they did it with.)
