We often need to use more that one verb in the sentence. To connect these verbs we use the conjunctions "and", "or", "but".
 
AND
We use "and" to connect positive verbs: (+) and (+).
Formula:
Subject + V/Vs + and + V/Vs
I study English and play computer games on the Internet.
  
OR
We use "or" to connect negative verbs: (-) or (-).
Formula:
Subject + V/Vs + and + V/Vs
I don't post comments or share photos online.
  
Note: You can use "or" to connect positive verbs if you want to emphasise that you do either one action or another but not both of them.
In the evening I draw or play the guitar. (It means that I either draw or play the guitar - I don't do both things.)
 
BUT
We use "but" to connect positive and negative verbs: (+) but (-) / (-) but (+).
Formula:
(+) but (-): Subject + V/Vs, but + Subject + don't/doesn't + V
or
(-) but (+): Subject + don't/doesn't + V, but + Subject + V/Vs
 I study English, but I don't study Italian.
  
If there are more that two verbs in the sentence, we put "and" or "or" before the last verb.
Formulas:
Subject + V/Vs, V/Vs and V/Vs
Subject + don't / doesn't + V, V or V
In the evening my friend usually listens to music on YouTube, makes videos and does his homework.
 
Note: try not to use more than three verbs in one sentence. If you need to use more than three verbs in your text, divide the text into two (or more) sentences.
