Examples from Quirk:
1. They found him worn out by travel and exertion.
2. They discovered him worn out by travel and exertion.
My remade sentences with "to be":
1a. They found him to be worn out by travel and exertion.
2a. They discovered him to be worn out by travel and exertion.
What is the difference between 1. and 1a.?
What is the difference between 2. and 2a.?
Thanks!
My thoughts:
"find" + object + to infinitive (oxfordlearnersdictionaries.com):
to find - to discover that something is true after you have tried it, tested it or experienced it:
They found him to be charming.
"discover" + object + to infinitive (thefreedictionary.com):
to discover - to learn something about:
discovered him to be an impostor
discovered the brake to be defective
My sentences with "that":
1b. They found (that) he was worn out by travel and exertion.
2b. They discovered (that) he was worn out by travel and exertion.
I conclude that:
1. = 1.a = 1.b = 2. = 2.a = 2.b
What mistakes do my thoughts have?
Thanks!
