On Thanksgiving Day, about 88 percent Americans will eat turkey. But one lucky turkey not only will not be eaten but also will become famous! Every year, turkey farmers present a turkey to the US president. But instead of eating this turkey, the president gives it a "pardon". The turkey is flown to Florida for a Thanksgiving Parade(游行). Then it lives on a farm for the rest of its life.

    Turkeys come from America and have been part of American culture for centuries. Benjamin Franklin even wanted the turkey to be America's national bird.

    Turkeys that are kept on farms are large, awkward birds that can not fly. But wild turkeys are quite fast. They can fly at speeds up to 88 kilometers per hour. They can also run at 40 kilometers per hour.

    Turkeys don't have ears. They hear by using a growth above their beaks(尖喙). But their hearing is five times better than human hearing.

    Turkeys are such interesting birds—no wonder Benjamin Franklin wanted them to be America's national birds!

    My name is Lily White. I don't have a brother, but I have a sister. Her name is Lucy.

    Green is Lucy's favorite color. Her bed and sofas are green. Lucy isn't a tidy girl. This is her room. Her radio and schoolbag are on the bed. She has three baseballs. Two baseballs are on the floor(地板) . Can you find the third(第三) one? Her pencil box and clock are on the table. And her model plane is on the sofa. Where is her ruler? Oh, it's under the table.

Dear Jennifer,

    It's Tuesday, February 11^th. I'm really busy today. At 8 o'clock I have a math class.I don't like math class. Then I have a science class. It's difficult, but It's interesting. Next, at 10:00, I have a history. It's boring. But I have PE at 11:00. That's my favorite subject. I have lunch at 12:00. After lunch. I have a music class. I like my music teacher, Mr. Morgan. He is a fun teacher. School is over at 2:00. After school I do sports for two hours. I'm so tired, but I'm very happy.

Yours,

Linda

Fleming saw many soldiers die from infections (感染) in their wounds as he worked in a hospital during World War I. This made Fleming decide to find a way to help the body fight infections. 

In September 1928, Fleming left some glass dishes on a bench in his laboratory for two weeks. When he came back, he noticed something puzzling. Bacteria (细菌) were growing on all the glass dishes except one. On this dish mould (霉菌) had started to grow—the kind found on old bread. The mould seemed to be giving off something that stopped the bacteria from growing. Fleming called it "mould juice". He tried it on other bacteria, and it killed them, too. Fleming became wild with joy and named it penicillin. 

Unfortunately, Fleming's boss thought he was wasting his time and it was impossible to kill bacteria at that time. Fleming did a few more experiments with penicillin, and he also wrote about it so other scientists could learn about it. However, because no one seemed interested in his discovery, he forgot about penicillin and started to work on other things. 

In 1939, Ernest Chain, a scientist, and his boss, Howard Florey, were looking for medicines that could kill bacteria. They discovered Fleming's notes and decided to test penicillin. In 1940, they gave penicillin to some sick mice, who survived later. But those who didn't get it died. Florey declared: "It looks like a miracle!" By 1943, the final tests on humans were finished successfully and the world had its first antibiotic (抗生素) medicine.
