She wrote one of America’s best loved children’s books.In 1868, an American publisher asked Louisa May Alcott to write a book for girls. At first, she was not sure if she wanted to do it. She said she didn’t like girls.However, she decided to write the book finally. She told about her experiences growing up in the northeast of the United States. The book was quite interesting. Little Women became one of the most popular children’s books in American literature. It was published in more than 50 languages.Alcott was born in Pennsylvania in 1832. The Alcotts did not have much money. She triedteaching, sewing(缝纫) and taking care of children. She did not like any of these jobs.At the age of 16, she wrote her first book, Flower Fables. Her stories were exciting, but unreal. She sold them to newspapers and magazines for money.The first volume (卷) of Little Women came out in 1868. It made Alcott famous and get a lot of money.

Public education is free and most children go to schools near their homes. Schools in these early years are fun. The children learn to read and write. But they also play games and go on trips. There is no reason at such an early age for himto hit the books.The situation changes as children become older. The subjects become more difficult .Students must learn about world history, algebra (代数) , and the life sciences. Tests become more common. Pressure is growing to hit the books, study hard, and advance. However, most serious students only really begin hitting the books for long hours when they reach high school. High school students who hope to continue their education at a collage or university must take a special national test called the S-A-T .The test has two parts .The first part tests the student’s ability with numbers and mathematical skills .The second part tests the student’s ability in the English language. The S-A-T test is very important .A high school student who gets a high score on the two parts of the test has a good chance to enter a nice American college .For this reason, many students hit the books for months to prepare for the S-A-T.61. Form this passage, we can clearly know ―hitting the books means_______ .A. working hard for the futureB. studying a subject carefullyC. reading books in a hurryD. reading books with great effort62.

The students must spend much time preparing for the S-A-T.C Everyone would like to be remembered. A few people even try to do something that no one else in history has ever tried to do. These people sometimes have their names recorded in the Guinness Book of Records.Often it takes a group of people to do something unusual. One such team paddled(用浆划)a bathtub（浴缸）145 kilometers for 24 hours. Thisgroup had 13 members. They paddled their bathtub on a river near Ashford, Great Britain on May 28 and 29, 1983 .A month later, a racing team of hospital bed pushers in Avon ,Great Britain, pushed a hospital bed 16 kilometers in just 50 minutes! However, the distance record for hospital bed pushing is still held by the men of Bruntsfield Bedding Center.

I loved her and always wished she could spend more time with us but she worked Monday through Saturday.At that time my little brother was about four years old and he missed her so much all the time. One day, he cried, saying he wanted his “Mummy”.So I locked the house and carried him on my back to find his mummy.My stepmother worked very far away. After about an hour’s walk, my little brother got tired and fell asleep. Then I looked down and saw he’d lost a shoe while sleeping. I took him from my back and put him down. I knew we had to find that shoe because my step-mom wouldn’t be able to afford new shoes for him, but it would take too long to do it while carrying my brother. So I told him to stay where he was and I wouldrun and find the shoe and come back. A man overheard me and stopped me right before I walked off. He asked me, “You’re leaving your brother here to go to find the shoe? What if he isn’t here when you return？”I didn’t know how to answer that question. So he said, “People are always more important than things. It’s okay if you can’t find the shoe, but it isn’t okay to lose your brother over a shoe.”He asked where we were headed and I told him the fact. I remember him looking at me and smiling when I told him what I was doing. He took both my brother and me and put us in a taxi and sent us to our destination.81.
