I would like to ask about verb need to. There is an example of the sentence with need verb: 1. Standards need to be followed.
I wonder if there is a possibility to write a sentence this way: 2. Standards which are needed to be followed.
or even with skip the words "which are" 3. Standards needed to be followed
Is the sentence "standards needed to be followed" correct? I would like to write that there are some standards that are required to be followed, that e.g. company have to follow the standards. I put in that I would like to write this sentence in my master thesis.
