Grammar textbooks teach us most of the grammar rules that we should know. They cannot list out all the mistakes that we might make.
"to + past participle (...to received) 是錯"? You cannot say that unless you are only talking about infinitives.
"要變成 to +have/has/had +verb+ed(....to have received"? 錯! to + has/had + verb +ed 是錯的!
Grammar textbooks tell us that for infinitives, we should use the base form of the verb after the word "to".That is why we should not say "to received" or "to has/had received". We should say "to receive" or "to have received".
"或 Positive then Negative sentence係錯,要變成Negative then Positive sentence........"
I dont think so.
Do you mean I cannot say "I know she does not have that much money" nor "I am sure he is not the murderer"?
Do I have to change them to "I do not know she has that much money" and "I am not sure he is the murderer"? They have very much different meanings!!
Are you sure that "Positive then Negative sentence係錯"?

"I think you can't remember" has more or less the same meaning as "I don't think you can remember". In cases like this, we USUALLY say "I dont think you can remember". But this is not a must and therefore it is not wrong to say "I think you can't remember".

as for my examples, I dont think one can easily come up with "negative then positive" sentences that have exactly the same meanings. If we are not allowed to say "positive then negative" sentences, what should we do? Therefore, I guess it is unfair to say that "Positive then Negative sentence係錯".

I have found many "positive then negative" sentences in my dictionary. I think that would confirm that "positive then negative" sentences are not wrong.
e.g. The boy decided that he would not become a sailor.
We decided not to go for a holiday in Wales.
