and I did exactly what the author said, downloaded all packages after installation of the NLTK.
then just input"from nltk.book import *"
SUPPOSE:
>>> from nltk.book import *

Loading text1, ..., text9 and sent1, ..., sent9
Type the name of the text or sentence to view it.
Type: 'texts()' or 'sents()' to list the materials.

text5: Chat Corpus
text6: Monty Python and the Holy Grail
text7: Wall Street Journal
text8: Personals Corpus
text9: The Man Who Was Thursday by G . K . Chesterton 1908
