On a hot summer day, ice-cold watermelon serves up a delicious treat. Sure, the rosy flesh (果肉) quenches your
thirst (解渴). But now there are more reasons than ever for people to reach for a slice of watermelon.
Meet Dr. Alison Edwards. She is a scientist at the Agricultural Research Service. Scientists are people who come
up with new ideas called theories (理论). They usually do scientific research to test their new theories. That's how
they find out if a new idea is a good one, or if the new idea will bring an even better idea.
At her lab, Dr. Edwards recently learned more about the secrets of why watermelon is good for you!
Dr. Edwards has known for a long time that watermelon has vitamin C. But recently she learned that watermelon
also has lycopene (番茄红素). It is something that gives tomatoes and watermelon their rosy red color.
What's so special about the lycopene in watermelon?
Dr. Edwards says that watermelon and tomatoes both have lots of lycopene. It seems that your body can use the
lycopene from watermelon more easily than the lycopene from raw (生 的) tomatoes. In fact, the lycopene from
tomatoes is more easily absorbed (吸收) inside your body once they have been cooked.
