The story of Dr. Percy Julian is an example of one man’s hard work and bravery. Percy was born in 1899 in Alabama, US. Because he was African-American, he couldn’t go to the same schools as white children. The schools he went to did not teach science. And yet, he had a strong interest in chemistry.
After college, Percy wanted to go to graduate school, so he could become a chemist(化學(xué)家). But one school after another turned him down because of his skin color. Finally, Harvard University accepted him. He got his master’s degree (碩士學(xué)位) at the age of 24. Then he went to Europe. In 1931, Percy became Dr. Percy Julian, a doctor of chemistry.
For the rest of his life, Dr., Julian worked with chemicals (化學(xué)物質(zhì)) found in plants. He knew that some plants had chemicals that could heal (治愈) people. So he made those same chemicals in a lab. That meant more people could get the medicine they needed. He developed chemicals that treated people with eye diseases and ease (減輕)the pain that some people had in their bones. Dr. Julian also used chemicals to invent many new products.
After working at a company in Chicago for many years, Dr. Julian opened his own lab. Then, he started a school to teach young people to be chemists. Dr. Percy Julian died in 1975. Today, his discoveries (發(fā)現(xiàn)) continue to help millions of people.

ABOUT THE BLACK BEAR
Description: Black body and head, brown nose, and large ears that stick out
•Size: 150 to 600 pounds, 4.5 to 6.5 feet long
•Living space: Heavily wooden area
•Food: Plants and small animals
Imagine this situation: You go out to your backyard, and you see a bear smelling your rubbish bin. Or you go into your garage(車庫) to get your bike and find a bear there. What would you do? People in some parts of Florida think about these situations a lot. They have been running into black bears more and more often. This is frightening and dangerous for both bears and people.
The number of cases of people and bears running into each other has gone up. In 1978, just one case was reported. In 2002, 1,340 cases were reported. These cases are called “conflicts”. Studies show that the number of conflicts in Florida is going up.
Some people think that human-bear conflicts are going up in Florida because there are more bears. Actually, it’s just the opposite. The number of bears is going down. In the early 1900s, there were about 12,000 black bears in Florida. Today, no one is really sure how many black bears are left. People think the number is from 1,500 to 3,000. So why are human-bear conflicts increasing so rapidly? There aren’t more bears, but there are more people.
There are many people who want to protect the Florida black bear. Here are some of the things that people in Florida are doing:
Teaching school children about the Florida black bear with a special program that includes a slide-show, games, and activities.
Choosing carefully where roads are built or widened so that wild animals will not be harmed by the traffic.
Holding a yearly festival for families with arts, food, and information on the bear.
1.What does the underlined word “conflicts” in the second paragraph mean?
A. Bears living in Florida in 2002.
B. Studies of black bears in Florida.
C. Fights between people and black bears.
D. Cases of people and bears running into each other.
2.Which of the following is NOT true according to the passage?
A. Black bears live in thick woods.
B. People feel afraid when they run into a bear.
C. There are about 3,000 black bears left in Florida now.
D. The reason why human-bear conflicts are going up is that there’re more people.
