Ex Input:
Another fine book by the master . Poirot is given a case by his old pal Spence which takes him to a small village, where the fussy detective must unravel clues behind a crime in which the main  suspect has already been arrested and sentenced... Hercule's indignities at the run down boarding house he's staying at make up the bulk of the story's humor, but the mystery is great fun, too and I doubt anyone can guess the killer, unless you're paying amazingly close attention. The characters here are some of Agatha's most entertaining, and Mrs Oliver, with her uncanny intuition,  always makes a nice flighty side kick..

Ex Output:
POS

Racist Classist Megalomaniac Talks A Little About Heroin . After hearing some decent things about this book, I was surprised at just how uninteresting and often offensive of a read it turned out to be.  Marlowe is accurate in some of her depictions of heroin use in the East Village of New York and way off base in others.  I chalk this up to everyone's experiences being different (however, I certainly don't think a one-bag-a-day habit with weeks off in between makes her an authority on addiction by any stretch of the imagination).  What I don't understand is why she felt the need to go into such great detail about her rather boring life between her discussions of the dope world.  Most of her anecdotes had little to no bearing on the story she was trying to tell and were mind-numbingly dull.  I found her narrative to be very disjointed and incoherent.  But what I found most repugnant was her better-than-thou attitude towards those of a lower class or darker skin tone (e.g. assuming dark-skinned men who didn't think to aspire to become more than security guards must not have gotten support or affirmation in their homes growing up, like she did).  She herself says that she became interested in street-life and street people in order to increase her "coolness" factor.  Sure she dabbled in drug use and in the East Village culture, but that does not make her an authority, and she does not paint a very true portrait of either.  If you want a good portrayal of street life and heroin use from the inside, read Seth Morgan's Homeboy.  If you want elitist drivel, this book should do the trick

English Education majors and secondary English Teachers: check this out! . This text helped me to articulate the 'principles' of Standard English by examining our language in all its varieties scientifically and intuitively.    Such articulation necessates a thorough understanding of the notions of descriptive vs. prescriptive, standard vs. nonstandard, formal vs. informal, grammatical vs. ungrammatical, and constitutive vs. regulative.    This introductory text is written for the mature student who has  had little or no background in linguistics or traditional school grammar. Consequently, the authors begin by demonstrating how traditional grammar instruction with its eight parts of speech and semantic definitions falls terribly short of accounting for the many rule exceptions and illogicalities of langauge.     I highly recommend this text for English Education majors and secondary school English teachers.
