I used to watch TV or________ with my friends

两个或两个以上的动词不定式由连词and \or \than \but连接时,从第二个不定式起,往往省略不定式符号to.但如果强调对比之意时不省略.例如:
(1)She 'd like to take off her coat and have a break.
(2)The students are taught to read,write and do many other things.
(3)I t 's more difficult to do than to say .(强调语意前后对比)
(4)The teacher came not to punish you but to help you.(强调语意前后对比)
(5)I wondered whether to study or to work.(强调语意前后对比)
希望能帮到你哦.
