My teacher recommended a book serise titled "step by step" and another teacher asked me to listen to dialogues or aticles again and again until I can write down them all. of course , you should choose the ones which are suitable for you . "Deperate housewives" and "The twilight saga' are suitable for the intermediate, because the dialogues are about dialy life. "Harry Potter" is more difficult than the two I said above, because there are a lot of professional words about magic. Personally , the British TV serise "Sherlock" is suitable for the superior., because the speaking speed of Benedict Cumberbatch is too fast. Even if there are subtitles, I still can not follow him.

I couldn't agree more. Indian accent is the  most difficult accent to understand.

I don't know. We Chinese are not allowed to use google and facebook.

Maybe it means" they do not know what size of the bike he should ride, so you need to take him to the bike store to make sure what size is suitable" , so they use "size him". I am not sure. :)

I succeed in seeing vedios on italki by VPN, wow ~ LOL ~~

I am in China. When we  come across someone in the street, we always greet each other by the question" Have you had your meal?", which has the similiar meaning to "How are you?" in English-speaking countries. Actually ,  whether  you have already had your meal or not is not important. People just use it to start a conversation.
