Watching TV is not a good use of time I think watching tv is not a good use of time because the programs on TV are made for the public. They are very popular and attractive but maybe not what you need. So I think the best way is to find your video is to search on the website. Furthermore, TV programs are always arranged on the fixed time, which means you have to put your work aside and sit by the TV waiting for it even though your work are not done. That's very inconvenient. Hope you can make it more natural! Thank you for your kind help!
