8. Task
What items (words/chunks/collocations) can you identify in the following text?
Seventy-eight-year-old Emily Morrison lives alone. She doesn’t go out much, so Emily was very pleased when a smartly-dressed young man appeared at her door offering a shopping service. His hair was short and tidy, and he wore a nicely-ironed white shirt and smart black trousers. He promised that her shopping would be in her house within an hour so she gave him her shopping list and credit card details. Her shopping was indeed delivered within an hour. However, when she received her credit card statement at the end of the month, Emily found an $800 charge for clothes purchased in a fashionable Los Angeles boutique that she knew nothing about. She had been deceived by the well-dressed young man.

9. We found that about 1/5 of the text could be assigned to ‘chunks’.
But textbooks teach predominantly single words!
