Dear sir,

I don't understand about the meaning of some sentences which having their structure as Subject + Verb to be + To + V1, such as

He was to receive $1,000 in each month for this job but he was never paid.

I guess this sentence would have meaning that the subject, he, was supposed to earn $1,000 for his salary. It should be replaced with the normal structures and re-written as

He was supposed to receive $1,000 in each month for this job but he was never paid.

Or

He was promised to pay $1,000 in each month for this job but he was never paid.

Therefore, Subject + Verb to be + To + V1 is Subject + Verb in for of passive voice. Do I understand in the right way?

Tony
