Hello,
These two sentences make me confused when I compare them.
This is my main confusion or question:
Why don't we use present participle [
standing] in number 1 and why don't we use infinitive [
to collect] in number two?
The two sentence above look similar in their construction but why 1 is
to and the second one is
ing?
