I have added a list of questions to each story page. Students can use these questions to check their comprehension after they have read a story. The answers can be found at the bottom of each page.
Vocabulary - I have used the VocabProfile (vocabulary profiler) at www.lextutor.ca/vp/ to help choose which words to add to the "vocabulary help" section of each story. This profiler sorts the words according to the frequency with which the word appears in the language at large. There are four categories - first thousand, second thousand, academic words, and all the rest ("offlist"). In general, I have added words from the last three categories (K2, AWL, offlist) to the vocabulary lists on this site.
The definitions for the vocabulary words on this site come from one of three sources, the Cambridge Learner's Dictionary (online at dictionaries.cambridge.org - no www), www.wordsmyth.net, or www.thefreedictionary.com
