题目内容：

    Sally Smith is an unbelievable woman who looks like a fit 40-year-old, although she just turned 70. She follows a special raw diet and only drinks rainwater.

She looks so young that people mistake her for her daughter when she’s out with her husband of 54 years, but I think he isn’t complaining.

Mrs. Smith says the secret to her beauty lies in her special diet, consisting of organic vegetables, fruits, seeds and nuts grown in her own garden; she calls it the “fountain of youth”. The woman doesn’t touch anything that has been cooked.

And another strange thing she does is to collect rainwater, to keep her garden blossoming, but also to drink. But the resident of Miami-Dade County, Florida, didn’t always have such a healthy lifestyle. In fact, she consumed meat regularly, as her husband used to own a meat factory way back in the 1960s. It was then that she decided to change her eating habit forever. And what a great decision that was! I mean, just look at her!

When she started off, Mrs. Smith was just looking for a few health benefits and never expected that she would look like a 40-year-old at the age of 70. Over the 27 years, she has been eating raw food, and she has written two booklets called Journey to Health and also produced a DVD containing all her healthy secrets.

Her husband, Mr. Smith, wishes he had followed her example, because now he looks much, much older and also suffers from diabetes (糖尿病) and high blood pressure. He takes prescription medicine every day, but Sally doesn’t even take an aspirin.
