About a month ago, when my younger son was preparing for PSAT, I started sending him daily news article that uses SAT level vocabularies. Most articles are from New York Times. Their website has a nice feature that you can double click on a word, then a window pops up to show the dictionary entry for the word.
I have enjoyed the experience of reading and selecting articles. Authors include Nobel Prize winner, Paul Krugman and Pulitzer prize winner, Maureen Dowd etc. A new page, Daily Vocabulary Building Reading, is started on this website to collect the entries.
I welcome your feedback. If you like to receive these daily articles, I am happy to include anyone in my mailing list.
