Back in 1988, Red Delicious made up 70 to 80 percent of the domestic apple market. Over the years, farmers sold a lot of them because they looked great. But they had a floury texture (质地), and people want an apple that's firm, crisp(脆的)and juicy. I started searching for one. By 1994, threatened by varieties from Japan and New Zealand, the U.S. apple industry and Washington State University agreed that we had to grow our own.
First, we cross-pollinated(授粉) existing apples: Collect pollen from one flower, put it on the tip of a pencil eraser, and rub it into another. We crossed dozens of crisp, tasty varieties such as Gala, Fuji, and Pink Lady. But the best breed came out of Honey Crisp and Enterprise parents. We grew the cross-bred seeds into 5-foot trees, grafted those to rootstocks(根茎) to make them start producing quickly, and planted them in evaluation gardens. A few years later, they fruited—and we began tasting.
So I would walk down long rows of hundreds and thousands of trees, and when I found an attractive fruit, I'd bite, chew, spit it out. Most were terrible, but when I found one with good texture and taste, I'd pick 10 or 20 of them. Then I put them in cold storage to see how they would hold up after a few months. After that, three or four researchers sat down and tasted every apple. We checked acidity and sugar levels, which can break down over time, and tested firmness and crispness using instruments that measure pressure and cell breakdown.
When we found exactly what we wanted, we planted and tested them all over again. Eventually, we ended up with the Cosmic Crisp. It can spend nine to 12 months in storage, and stay crisp, firm, juicy and sweet.
Our lifestyles today are very busy. We have family, school, sports, entertainment and social activities to fit into a time that seems never enough. We need to be healthy to meet the demands of daily life. But what does it mean to have a healthy lifestyle?
To have a healthy lifestyle, we need to:
◆ eat different kinds of healthy food most of the time
◆ do exercise often
◆ have time to relax
◆ get enough sleep to give our bodies time to grow healthy and strong
Read about a normal day in the lives of two children.
Abbey gets up at 7:00 am, feeds the dog, and has cereal and a glass of juice for breakfast. She walks to school with her friend, Julia. She has a bag of chips for a morning snack, drinks water, and has a chicken and lettuce sandwich with a banana for lunch. She likes to play soccer with her friends at lunch and morning break time. She walks home with Julia, has some crackers with cheese and juice for afternoon snack and plays with the dog for a while. She plays computer games for an hour or two before dinner, then has a shower and does her homework. She watches her favorite television show for an hour, then usually goes to bed at about 9:30 pm. | Carl gets up at 8:30 am and has two pieces of bread with jam and a glass of milk for breakfast.
