Exercise 7-1: the throng of thermometers
    I'm going to read the following paragraph once straight through , so you can hear that no matter how fast I read it, all the THs are still there. It is a distinctive sound, but, when you repeat it, don't put too much effort into it. Listen to my reading.
    The throng of thermometers from the THuringian THermometer Folks arrives on Thursday. There were a thousand thirty-three thick thermometers, though, instead of a thousand thirty-six thin thermometers, which was three thermometers fewer than the thousand thirty-six we were expecting, not to mention that they were thick ones rather than thin ones. We thoroughly thought that we had ordered a thousand thirty-six, not a thousand thirty-three, thermometers, and asked the Thuringin Thermometer Folks to reship the thermometers; thin, not thick. They apologized for sending only a thousand thirty-three thermometers rather than a thousand thirty-six and promised to replace the thick thermometers with thin thermometers.
