I tried some online tests just now:
I am too tired _______ out. Besides, I have to wake up early morning.
I chose 'to go'. However, it turned out that I was wrong, according to the test maker. The correct answer is 'going'. Why do we use gerund here?
-> This 'too tired' is followed by (to-verb)
Can someone elaborate why the answer is 'going'? Please explain as thorough as possible, and give some statistics and maybe some scientific journals/data to back up your claim.
