a) As long as I understand I go on reading,
b) I do jot down the words I don't know & look them up when I have time, I like to build my vocabulary
c) Tenses in French are more or less like in English : imparfait = preterit and plus que parfait = pluperfect; passé simple = preterit too...
d) you want to think (and dream!) in the language ASAP, so don't translate when you read,
e) From time to time, do try to translate a page, just to check how different it looks and sounds--and how right it is to read in the original language
