Student or Learner
I want to learn the method of using of the above patterns "it is said that/it is thought that/it is known that/etc". It's okay none of you teaches me about them here. It would be enough if someone just provides me any website where I will be able to learn about them.
Great! I really wanted to have some examples though I didn't mention here. Because I am used with these kinds of sentences but I wanted to be more aware. Now I understand. If something is well-known by people and is very common to people, we can express it as "it is known/said/etc"
Thanks Raymott for the examples. I personally want more examples in terms of these kinds of sentences. Since I am used with them, now I just want to know, in how many ways they are (it is said/known/though/etc) used.
