1 . From civil rights to environmental protection, the following books of fiction and nonfiction cover a wide range of topics. And every young liberal（开明人士）should read them.
An Inconvenient Truth by Al Gore
Al Gore caught the attention of the world with his 2006 book An Inconvenient Truth, which was later turned into a movie. Based on his lecture tour on global warming, the work explains climate change in a user-friendly way and opens the public’s eyes to the plight（困境）of our planet.
The Grapes of Wrath by John Steinbeck
When John Steinbeck won the Nobel Prize in Literature in 1962, he was praised for his realistic and imaginative writings, including The Grapes of Wrath. This book centers on a family of Oklahoma farmers who are forced off their land during the Great Depression. While it touches on timely issues such as labor unions and agricultural industry changes, it also explores universal themes of power, family, self-interest and dignity.
The Jungle by Upton Sinclair
Focusing on the meat-packing industry in Chicago, Upton Sinclair’s 1906 novel The Jungle explores the life of immigrant workers in the early 20th century. The best-selling account actually made President Theodore Roosevelt pass the law about food safety that year.
The Conscience of a Liberal by Paul Krugman
Economist and Nobel Prize winner Paul Krugman presents 80 years of US history in The Conscience of a Liberal, which examines the fall and rise of economic and political inequality. Many believe the 2007 book was a clear call for progressives（进步人士）to take control of the country’s economic future.
