What a great album!!! I never knew she sang as well. I have seen her in French movies and enjoyed greatly her acting in those movies. Now I even adore her more, because not only can she act, but she can sing as well!!!Go Charlotte Go!!!! Can't wait for her next album.

If you need a grammar reference, this may well serve until you find a better one. It might be of greater utility if the tone wasn't vaguely condescending and pedantic, and it eschews the panoply of actual examples in favor of definitions. To wit: the 2nd person singular present perfect conjugation of "to love" results in "If you have been loved..." gives me one (singular) example but not the rationale of when to use this. The density of the text preceding the example conjugations will require your own self-study to master (if you must) the ability to spin off a subjunctive 3rd person plural present tense conjugation.The best recommendation I can offer for this is as a companion for language learners who need a quick reference for English analogs of other-language conjugations, such as when you try to conjugate "falar" and need to know which one to use.--#

I don't know what it is about this movie but it's a classic 80's flick! Mark Harmon is at his best. The plot is a little predictable but it's entertaining and takes you back to the decade past.
