Query: Missed the Mark

I am living in China and taking Mandarin lessons - I had a friend bring me this book without having looked at it. It has a major flaw - the Pinyin (the a-b-c version of Characters) does not have the tone markings. This means that you will not be understood without the correct tone - I know that from repeated experience. For instance "mai" can be pronounced 4 different ways each with a different meaning - pronounced in 4th tone is to SELL and 3rd tone is to BUY and 2nd tone is to BURY. Look at the learning dictionaries by Tuttle publishing with the author of Li Dong and then get a Rough Guide or Lonely Planet phrase book -they show Pinyin with tone marks. A language DVD and hand recorder would help you to match the tones very well if you are serious.
