1. Watch TV all day and you will be couch potato!

2. Watch TV all day and you can be couch potato!

Can 2 mean the same as 1?

 

Thanks!

Hi, Ruifeng,

Please note that the expression "couch potato" (just like the head noun "potato") is a count noun, so it should be preceded by "a."

That said, I don't think  (2) can be equivalent to (1). While (1) expresses cetainty, (2) only expresses possibility.

I agree with Gustavo and would like to point out, in case it isn't already clear to you, Ruifeng, that the coordinate structures you are using have a conditional meaning. It's the difference between "If you watch TV all day, you will be a couch potato" and "If you watch TV all day, you can be a couch potato." The second sentence, then, states that one will have the opportunity to be a couch potato if one watches TV all day, whereas the first states that watching TV all day will make one a couch potato.

 

Thank you, Gustavo and David!

Can 2 mean both the two meanings below:

1. Okay, if you really want to be a couch potato, you can choose to watch TV all day.

2. I am warning you, if you watch TV all day, you are very likely to become a couch potato!
