Nelle Harper Lee was born on April 28,1926. Since Lee’s mother was mentally ill, she was raised by her lather. She became very close to her father.

The naughty Lee loved reading, and would make up stories with Truman Capote, her neighbour who was two years older than her. Seeing his daughter’s imagination, Lee’s father gave her a typewriter.

In high school, Lee developed an interest in English literature. After graduating in 1944, she went to the all-female Huntingdon College in Montgomery. Lee stood apart from the other students. She could have cared more about fashion, make-up, or dating. Instead, she focused on studies and writing. Transferring (转学) to the University of Alabama, Lee was known for being a loner and an individualist. Before her final year in the University of Alabama, Lee dropped out to become a writer. She moved to New York City where her childhood friend Truman was already a famous writer. While there, she worked on her first book — To Kill a Mockingbird. It won her the Pulitzer Prize in 1961 and was made into an Academy Award winning movie the following year.

To Kill a Mockingbird tells the story of six-year- old Scout and her brother who live in the town of Maycomb, Alabama with their single father Atticus. Atticus is a lawyer who defends blacks. At a young age, Scout lives in the surroundings of the terrors of segregation (隔离政策).

Then, in 2014, the first draft (草稿) of a new book — Go Set a Watchman was discovered among Lee’s papers. It is the story of 26-year-old Scout who returns to Maycomb to visit her father. She is shocked to find her father a changed man. He has turned into a segregationist!

The story shows the mixed feelings Scout has about the changes that have taken place in her homeland and her father. A loner for most of her life, Lee stayed unmarried, preferring to lead a small town life. On February 19,2016, Lee passed away at the age of 89.

   Isaac Asimov is one of the most famous science fiction（科幻小说）writers of all time. He moved from Russia to the United States in 1923.He was a teacher at Boston University and began writing science fiction stories in 1939.His most famous works are the Foundation books and the Robot stories. He died in 1992 at the age of 72.

"There are not many people who have invented a useful scientific term，and although I did it unknowingly，I am not going to let anyone in the world forget it，"said Isaac Asimov. He was talking about the word "robotics" —the study of robot behaviour.

Asimov wrote several stories about robots between 1940 and 1990.One of the special features of the robots in these stories was that they were programmed to follow the Three Laws of Robotics.

The First Law: A robot must not hurt a human being，or allow a human being to be hurt.

The Second Law: A robot must obey orders by human beings unless these orders conflict（冲突）with the First Law.

The Third Law: A robot must protect itself unless this conflicts with the First or Second Law.

In Asimov's stories，the robots must follow these laws so that they do not attack the humans that created them.

Some scientists think the Three Laws of Robotics are hard to realise in real life. On the other hand，some say that the laws are great for science fiction but completely useless in real life. For example，if the laws really worked，robots couldn't be used in wars，as this would break the First Law. Since the army is one of the biggest supporters for robotic research，it is very unlikely that an attempt to follow these rules will happen.

According to Asimov，one thing is certain："Robots are changing the world and driving it in directions we cannot clearly foresee（预见）."
