I am interested in English Grammar.Today I would like to know about gerunds and to-infinitives.
I learned that the gerund has the nuance of past; on the contrary, the to-infinitive has that of future.
Obviously we can see these differences;
I forget to clean my room, and I go back.
I forget cleaning my room, so I did not lock the door.
I learned that the following sentenses have almost the same meaning.
I like reading books.
I like to read books.
It began to rain.
It began rainig.
Although these forms are different, why is it interpretted as the same meaning? I really wonder about it.
From the view of the speaker of English, how do you use them respectively?
And also, why does the gerund have the sense of past tense?
I know why To-infinitive has future tense. "To" itself has such a nuance, right?
Moreover, there are Verbs that are used with only the Gerund or to-infinitive:
afford +to-infinitive only
How are these usages born?
I'd like to know about them...And if there are some recommended books concerned with this, I want to know it.
That is my question.
