1 . As you walk around the UK in March, you might notice that some people are wearing a daffodil(水仙花) on their coats. The British wear these yellow flowers to show they support one of this country’s best-known charities: the Marie Curie Cancer Care.

The Marie Curie Cancer Care tries to ensure everyone diagnosed with cancer is cared for in the best possible way. It also helps fund research into possible cures through other organizations. Founded in 1948, it has been continuing with its goal ever since.

The charity was named after Marie Curie, a renowned scientist. She experimented with newly-discovered elements to create the theory of radioactivity. Unfortunately, over-exposure to the radioactive elements made her develop a disease and die in 1934. Marie Curie won the Nobel Prize in two different fields. Because of her pioneering work which led to chemotherapy (化学疗法), the charity shared the name of Marie Curie.

The daffodil is one of the first plants to flower during spring in the UK, which marks the return of flowering plants to the ecosystem after winter. Because of this, the charity uses the daffodil as a metaphor for bringing life to other people through charitable giving.

Everyone you see wearing a daffodil has donated money to the charity, but each daffodil is worth only what you want to pay for it. The charity does ask that you stick to a minimum amount of £1.

The charity encourages people to start wearing their daffodils at the start of March, when the “Great Daffodil Appeal” kicks off. But that doesn’t mean you can only wear them in March. People are sometimes seen walking around with daffodils on their clothes all year round.

3 . At 1:43 a.m. October 5, 2022, Stanford chemist Carolyn R. Bertozzi was awakened by a phone call from a Nobel committee representative who told her, “You have 50 minutes to collect yourself and wait until your life changes.” Instructed not to share the announcement outside of her tightest inner circle, the first person Bertozzi called was her father, a retired physics professor from MIT. “He’s 91 and, of course, he was just overjoyed,” said Bertozzi.

Carolyn Bertozzi, born October 10, 1966, Boston, was awarded the Nobel Prize in chemistry for her development of bioorthogonal reactions, which allow scientists to explore cells and track biological processes without disturbing the normal chemistry of the cell. She shares the $10 million Swedish kronor (about $1 million USD) prize equally with Morten Meldal, professor at University of Copenhagen and K. Barry Sharpless, professor at Scripps Research “for the development of click chemistry and bioorthogonal chemistry.”

Carolyn received a bachelor’s degree in chemistry from Harvard University in 1988 and a doctorate in the same subject from the University of California, Berkeley in 1993. She was a postdoctoral fellow at the University of California, San Francisco, from 1993 to 1995. She became an assistant professor at Berkeley in 1996 and a full professor of chemistry and molecular and cell biology in 2002. She also held an appointment as a professor of molecular and cellular pharmacology from 2000 to 2002 at the University of California, San Francisco. In 2015 she became a professor of chemistry at Stanford University.

“I could not be more delighted that Carolyn Bertozzi has won the Nobel Prize in chemistry,” said Stanford President Marc Tessier-Lavigne. “In pioneering the field of bioorthogonal chemistry, Carolyn invented a new way of studying biomolecular processes, one that has helped scientists around the world gain a deeper understanding of chemical reactions in living systems. Her work has had remarkable real-world impact, providing new diagnostic and therapeutic approaches to treat disease. Carolyn is so deserving of this honor, and all of us at Stanford are too proud to call her one of our own.”

Carolyn’s bioorthogonal reactions have been used to study how cells build proteins and other molecules, to develop new cancer medicines, and to produce new materials for energy storage, among many other applications.

1. Why does the author mention the phone call Carolyn received in Paragraph 1?

A．To introduce the background information of Carolyn.

B．To reveal a conversation between two scientists.

C．To arouse the readers’ interest in the passage.

D．To show the urgency about the information.

2. What can we learn about Carolyn from paragraphs 2 and 3?

A．Her education and success.	B．Her delight and pride.

A．He wants to cooperate with Carolyn.

B．Carolyn has found a new cure for cancer.

C．He benefits greatly from Carolyn’s findings.

D．Carolyn’s findings are of great significance.

4. What is the text?
