福建省福州市2019届高三上学期英语期末考试试卷
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.
Field Trip Day
On Friday, May 16, our class will take a field trip to North Park Zoo. The zoo has lions, elephants, and other interesting animals. Many of the animals we have been studying will be there for us to closely examine.
Our class will be divided into six teams. Each team will have five students and one leader. The leaders are listed in the table.
Team 1 | Miss Banker |
Team 2 | Mrs. Lopez |
Team 3 | Mr. Harper |
Team 4 | Miss Abel |
Team 5 | Mr. Soto |
Team 6 | Mrs. Thomas |
What You Need to Know
The cost is $1.00 for students to enter the zoo. We will leave the school at 9:00 a.m. and return at 2:30 p.m.
On the morning of the trip, the students will be divided into teams. One student from each team will receive a camera. The cameraman will take pictures of the team, the animals, and other fun sights at the zoo.
All members should wear blue shirts. Be sure to wear comfortable shoes because we will be walking all day. Please bring a bag lunch and a drink. We will have a picnic at the park inside the zoo. Bring a healthy snack, such as a piece of fruit and a drink, for later in the day.
When we are at the zoo, always remain with your team. Do not leave the team without asking permission from the team leader.
Feeding the Animals
The ONLY animals that students are allowed to feed are those in the children's Zoo. Special food can be bought at the zoo for 25 cents and given to these animals. Do not feed your lunch to them. It is not food for the animals.
