Hi Alc, The first, second and third are all grammatically fine. The fourth is wrong because "slept" refers to a past action, whereas "watch" refers to a present action: the sentence implies that while he slept (past tense), you are currently watching TV--which doesn't make sense! Regards, Sam

dimsumexpressJust a quick point for future reference. When you use "while" in the construction, use "it" on the event that takes the longer time. i.e. While I was waiting for dinner to be ready, I went to take a shower. "While I was on the phone with Julie last night, Paul came by to borrow my note"I haven't found any "it" in your examples. Can you elaborate?
