Many groundbreaking inventions have emerged from unexpected moments. In 1928, Alexander Fleming left a Petri dish of staphylococcus bacteria uncovered while on vacation. Upon returning, he noticed a mold growing in the dish had killed the bacteria around it. This accidental observation led to the discovery of penicillin, the world's first antibiotic, saving millions of lives.
Another iconic example is the microwave oven. In 1945, engineer Percy Spencer was testing radar equipment when he noticed a chocolate bar in his pocket had melted. Intrigued, he experimented with heating food using microwaves, leading to the first microwave oven. Initially large and expensive, it evolved into a kitchen essential.
Even the humble Post-it Note has an accidental origin. In 1968, scientist Spencer Silver developed a weak adhesive but couldn't find a use for it. Years later, colleague Arthur Fry used it to mark pages in his hymnbook, realizing its potential for reusable notes. The product was launched in 1980 and became a global phenomenon.
These stories highlight the role of curiosity and observation in invention. Fleming, Spencer, and Fry all turned accidents into innovations by asking, "What if?" Their examples show that innovation often stems from noticing the unexpected and pursuing its possibilities. As the saying goes, "Chance favors the prepared mind"—and a curious one at that.

Marie Curie, born in Poland in 1867, is a pioneer in the field of radioactivity and the only person to win Nobel Prizes in two different sciences. Her journey began with a deep curiosity about the natural world, particularly the newly discovered element uranium. While studying at the University of Paris, she noticed that uranium salts emitted rays stronger than those of uranium itself, a phenomenon she termed "radioactivity."
Curie's research was groundbreaking but faced numerous obstacles. In the early 20th century, women in science were often dismissed, and she worked in a poorly equipped lab with little funding. Despite this, she persisted, isolating two new elements: radium and polonium. Her discovery of radium's radioactive properties opened doors to cancer treatment, though the dangers of radiation were not yet understood. Curie herself suffered from radiation sickness due to prolonged exposure, yet she continued her work.
During World War I, Curie developed mobile X-ray units to help surgeons locate bullets in wounded soldiers, saving thousands of lives. Her dedication to science and humanity made her a global icon, though she remained humble, once refusing to patent her discoveries so they could benefit all of mankind.
Curie's story is not just about scientific achievement; it's a testament to curiosity and resilience. She once said, "Nothing in life is to be feared, it is only to be understood." Her work reminds us that curiosity, coupled with courage, can overcome even the greatest challenges.
(1)、What did Marie Curie term the phenomenon of uranium emitting rays?A、Radioactivity B、Radiation C、Uranium salts D、Polonium(2)、What obstacle did Curie face in her research?A、Lack of scientific interest B、Gender discrimination and poor facilities C、Opposition from the government D、Fear of radiation(3)、How did Curie contribute during World War I?A、By inventing new weapons B、By developing X-ray units for field hospitals C、By training nurses D、By patenting her discoveries(4)、Why did Curie refuse to patent her discoveries?A、She didn't believe in patents B、She wanted them to benefit everyone C、She forgot to apply for patents D、Her research was incomplete(5)、What is the main message of the passage?A、Curiosity and resilience drive scientific progress B、Women face more challenges in science C、Radiation is dangerous but useful D、Nobel Prizes are important for scientists -
