Four sources for audio and video streams

Here you can have access to the NPR of the NYC region.  It could be useful if you want to improve your listening comprehension of American English.  You can listen to the live FM broadcast or go their show archives.  I personally like Radiolab, Selected Shorts and Fresh Air among the shows they air.

Here you can have access to the BBC website, which also airs on the WNYC in the mornings Brussels time.  It could be useful to improve your listening comprehension of British English.  They also have links under "Learning English", where you can find numerous tools for learners of English as a second language.

Here you can have access to the audio and video streams on The Economist website.  This again is a good source for improving British English listening comprehension. I recommend using "The Week Ahead", which is released after 5:00PM every Friday.

Here you can have access to TED, which is a good source for numerous talks on a very wide range of topics.  Most talks are given by Americans and Canadians, but there are also other speakers of different nationalities, including some British.

Plans

Here are the four different functions we can use to talk about plans:
1. I will/shall call you in 10 minutes. (spontaneous)
2. I am going to spend the evening at home. (premeditated in spoken English)
    I will/shall be spending the evening at home. (premeditated in written English with an action verb)
    I will be in New York during Easter.  (premeditated in written English with a state verb)
3. I am flying to New York at 8:00AM tomorrow. (premeditated and arranged with an action verb)
    I am in New York during Easter. (premeditated and arranged with a state verb)
4. My Flight departs at 8:00AM tomorrow. (time-tabled event)
