Productive time now... often running two hours a day Mandarin study, spread throughout the day. Here are some of the resources I've been using most often:
o Penton VocabuLearn, on Nano and cassette. The Nano's pocket size means I can wear it more often. The cassette is used around the house. I try to anticipate and repeat, out loud, and sometimes try to act out expressions too. Lately I've been going to sleep to this, repeating and acting out as long as I'm awake. (Buying tip: The CD version has been repeatedly postponed, and the Audible.com iPod purchase I made sounds like it was taken from the 1993-era tape recording.)
o KTSF Mandarin News. My DVR records it each evening, so I get five hours of new material for the week. The speaker styles vary greatly within a news broadcast -- some interviewees speak more slowly than anchors. The captions in characters help me identify what I'm hearing, particularly with regional and social differences among speakers. I watch the soap operas and children's shows too, but their evening news is big for me right now.
o The book "Intermediate Chinese" [Yip Po-Ching & Don Rimmington; Routledge] is usually in my daybag. It contains grammar, but also contains many examples, in character, phonetic, and English translation -- I can switch among study modes with a single book. I alternate with others, like the transcription books for some of the audio courses, or grammars or colloquial guides, but this particular Routledge book currently has the edge.
o For dictionaries, I've been reading the Oxford Starter more again recently, particularly to look up terms from the Penton vocabulary course while going to sleep. I've been carrying around their Mini version when my pockets have allowed, but I picked up a smaller Langendorf pocket dictionary today. (I'm still trying to dope out the electronic dictionary I picked up in Shanghai... finally found the different parts of the house where the manuals and the unit was... first time I tried reading it outside, I think I lost the manual. Gotta learn it.... ;-)
o Other audio materials I've used recently are the Living Language recordings, the "Learn to Speak Chinese 2" (publisher name is not on lid, but it's a burgundy box I bought on Clement St), the cassette phrasebooks from the General Language Record Co. in Kowloon (many Chinatown & Clement bookshops), "Living in Beijing" from Sinolingua (although I don't like all that initial talk about filling out forms in the proper order ;-)... I've got the Language/30 cassettes here that I haven't listened to for awhile, and there's one or two others around the house, but these are the materials I've used over the last month or so.
o For devices, it's a nice Sony tape cassette in a leather waistbelt with earbuds while doing chores, exercising, odd times. The Nano has about a gigabyte of CD courseware -- the "Making Connections" on Cheng & Tseng is great for natural conversation, or I could switch to progressive courseware with dialogs and drills, or go straight vocabulary, or music. On my office PC I have some old courseware in various languages, but I have difficulty listening to language instruction while trying to think of what I'm reading... it's on my list to update, though.
If I had a comfortable place to read, particularly outside, then I think I'd read a lot more... best place I've found so far is the SF Brewing Company that's 'way out in North Beach. I wish there was a place near here where I could get good kimchee, too.... ;-)
