#Use Ruby script to download a webpage ranging from 15274.html to 
15334.html
# and here is an example
#download a webpage based on an address

require 'open-uri'
require 'threadlimiter'

#address='http://www.qenglish.com/samples/15334.html'
#....
#address='http://www.qenglish.com/samples/15274.html'

addresses=[]
address1='http://www.qenglish.com/samples/'
address2=''
address3='.html'


# create the address
(15274..15334) .to_a.each do |i|
  addresses<<(address1 + i.to_s+  address3)
end

#download the files
addresses.threaded_collect(1)do |a_uri|
  open(a_uri) do |a_file|
    f_name=File.basename(a_uri)
    open(f_name,'wb')   do|r_file|
      a_file.each_line do |a_line|
      r_file.write a_line
end
end
end
