We sometimes use an ing form after to.
I look forward to seeing you. (NOT . . . to see you.)
I'm not used to getting up early.
These structures may seem strange.
In fact, to is two words:
a. a part of the infinitive
I want to go home.
Help me to understand
b. a preposition
I look forward to your next letter.
I prefer meat to fish.
I'm not used to London traffic.
After the preposition to, we can use an -ing form, but not usually an infinitive.
I look forward to hearing from you.
(NOT . . . to hear from you.)
I prefer riding to walking.
I'm not used to driving in London.
If you want to know whether to is a preposition, try putting a noun after it. Compare:
a. I want to your letter. (Not possible: to is not a preposition. Use the infinitive after I want.)
b. I'm looking forward to your letter. (This is all right, so to is a preposition. Use the -ing form after look forward to.)
Rules to play 8 Ball Pool
If the eight ball is pocketed or driven off the table on the break, it will be spotted or the balls will be re racked. (See 3.3 Break Shot and 1.4 Spotting Balls.) No other object ball is ever spotted.
