I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.

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 have no idea how I was talked into watching this movie. I totally believe this was a waste of good film-and a lot of it. A young Daniel Day Lewis with a hipper Fonz impersonation and a whiney Juliette Binoche. Only Lena Olin was worth watching, but not for any depth or anything. This film actually made a communist invasion dull. I absolutely didn't care for this couple. Below par acting, horrible direction, terrible editing, annoying soundtrack and dialogue so bad I think someone should take away the screenwriter's guild card. Don't waste your time on this one.
