Before we read, let's unlock the words you'll need. Each one is hidden in a sentence. Read it aloud and say what you think the bold word means from the rest of the sentence — then reveal it and see how close you were.
Read each part. After it, there's a quick comprehension check (try the questions from memory first), then one thing to discuss.
She was born Maria Skłodowska in Warsaw in 1867, at a time when Poland did not appear on any map — her country had been swallowed by the Russian Empire, and even her language and history were forbidden in school. She was brilliant, hungry to learn, and completely barred from the path her mind deserved: the University of Warsaw did not admit women.
So she learned in secret. Maria joined what students called the "Flying University" — illegal evening classes that moved from flat to flat so that the authorities could never catch them. To reach the real laboratories of Paris, she made a pact with her sister: Maria would work as a governess and send money so that Bronisława could study medicine first, and in return her sister would later support her. For years she taught other people's children by day and studied physics alone by night.
In 1891, at last, she boarded a train for Paris and enrolled at the Sorbonne. She was so poor that she sometimes fainted from hunger at her desk, yet she finished top of her class in physics. There she met a quiet, gifted scientist named Pierre Curie, who shared both her laboratory and, soon, her life. When they married she chose to be known as Marie Skłodowska-Curie — keeping the Polish name of the country that had refused to teach her.
1. Why couldn't Maria study at university in Warsaw, and how did she get an education anyway?
2. What deal did she make with her sister, and where did it finally take her?
1. The University of Warsaw did not admit women (and Poland was under Russian rule, which restricted Polish learning), so she studied secretly at the illegal "Flying University," whose classes moved location to avoid the authorities.
2. She worked as a governess to fund her sister Bronisława's medical studies in Paris first, on the understanding that her sister would later help her — which eventually let Maria study physics at the Sorbonne.
In 1896 another scientist, Henri Becquerel, noticed that uranium gave off mysterious rays on its own. Marie made this puzzle her own. Measuring the rays with great care, she realised the energy came from inside the atoms themselves — a genuinely revolutionary idea — and she invented a word for the phenomenon: radioactivity. Then she went further. Studying a black ore called pitchblende, she found it was far more radioactive than its uranium alone could explain. Something unknown had to be hidden inside it.
To prove it, Marie and Pierre worked for four years in a freezing, leaking shed, stirring boiling cauldrons of ore by hand to isolate the tiny amounts of new material it contained. Their perseverance was rewarded twice over. They announced one new element and named it polonium, after Poland — a quiet act of patriotism on the world stage. Then they found a second, far more powerful one, which glowed faintly in the dark: radium.
In 1903 the Nobel Prize in Physics was awarded for the work on radioactivity. At first the committee planned to honour only Becquerel and Pierre; Pierre protested until Marie was named alongside them, and so she became the first woman ever to win a Nobel Prize. When Pierre was killed in a street accident in 1906, she took over his professorship — the first woman to teach at the Sorbonne — and pushed on alone. In 1911 she won a second Nobel Prize, this time in Chemistry, for isolating pure radium. To this day she remains the only person to have won Nobel Prizes in two different sciences.
1. What did Marie realise about where the rays came from, and what two new elements did the Curies discover?
2. What makes her two Nobel Prizes so remarkable?
1. She realised the energy came from inside the atoms themselves (and coined the word "radioactivity"). Studying pitchblende, the Curies isolated two new elements: polonium (named after Poland) and radium.
2. She was the first woman to win a Nobel Prize (Physics, 1903), and with her Chemistry prize in 1911 she became the only person ever to win Nobel Prizes in two different sciences.
Radium seemed like magic. It glowed; it could shrink tumours; for a while the public even put it in toothpaste and face cream. But it was a double-edged sword, and Marie had handled it with her bare hands for decades, carrying glowing tubes in her pockets simply to admire their light. When the First World War came, she refused to sit it out. She mobilised her science, designing mobile X-ray units — soldiers nicknamed them the "petites Curies," the little Curies — and driving them to the front herself, where they helped surgeons locate bullets and shrapnel in over a million wounded men.
All the while, the radiation was taking its toll. The very rays she had given the world were quietly destroying her own body. In 1934 she died of aplastic anaemia, a disease of the blood almost certainly caused by a lifetime of exposure to the materials she loved. She had never sought to grow rich from her work — she refused to patent the process for producing radium, insisting it belonged to everyone.
Her legacy proved enduring beyond anything she could have imagined. Radiotherapy still treats cancer today; her name marks elements, institutes and hospitals across the world; in 1995 she became the first woman laid to rest in the Panthéon in Paris for her own achievements. And there is one strange, haunting echo: her notebooks are still so radioactive that they are kept in lead-lined boxes, and anyone who wishes to read them must sign a waiver. A century on, her work has not stopped giving off light.
1. How did Marie use her science during the First World War?
2. What finally killed her, and what makes her notebooks famous today?
1. She designed and drove mobile X-ray units (the "petites Curies") to the battlefront, helping surgeons find bullets and shrapnel in over a million wounded soldiers.
2. She died in 1934 of aplastic anaemia, caused by decades of radiation exposure. Her notebooks remain so radioactive that they are stored in lead-lined boxes and readers must sign a waiver.
A biography is full of moments where two things happen at once, or one action follows another. Instead of writing two short sentences, fluent English often folds them into one — using a participle clause. It's economical, it flows, and the story above is built on it.
Combine each pair into one sentence, turning the first verb into an -ing clause.
1. She worked in a freezing shed. She stirred tonnes of ore by hand.
→ in a freezing shed, she stirred tonnes of ore by hand.
2. She measured the rays with great care. She realised the energy came from inside the atoms.
→ the rays with great care, she realised the energy came from inside the atoms.
3. She studied a black ore called pitchblende. She found something unknown hidden inside it.
→ a black ore called pitchblende, she found something unknown hidden inside it.
1. Working in a freezing shed, she stirred…
2. Measuring the rays with great care, she realised…
3. Studying a black ore called pitchblende, she found…
The -ing clause and the main clause share the same subject — here, "she."
Combine each pair using Having + past participle to show the first action was complete before the second.
1. She discovered radium. She refused to patent it.
→ radium, she refused to patent it.
2. She won a Nobel Prize in Physics. She went on to win a second in Chemistry.
→ a Nobel Prize in Physics, she went on to win a second in Chemistry.
3. She lost Pierre in a street accident. She took over his professorship alone.
→ Pierre in a street accident, she took over his professorship alone.
1. Having discovered radium, she refused to patent it.
2. Having won a Nobel Prize in Physics, she went on…
3. Having lost Pierre in a street accident, she took over…
"Having + past participle" stresses that the first event was over before the second began.
Each gap needs a past participle (-ed / irregular) opening a passive idea. Fill it, then read the sentence aloud.
1. to radiation for years, she slowly fell ill. (expose)
2. by a hunger to learn, she studied physics alone at night. (drive)
3. from the University of Warsaw, she found another way to learn. (bar)
1. Exposed to radiation for years, she slowly fell ill.
2. Driven by a hunger to learn, she studied physics alone at night.
3. Barred from the University of Warsaw, she found another way to learn.
The past participle carries a passive meaning — something happened to her — and usually explains a cause.
These three moves let you combine two ideas into one flowing sentence — exactly what you'll lean on when you tell Marie's story, and someone else's, in the Speak tab.
You've read the story and you have the words — so now the real thing is within reach. There's a full podcast episode that tells this story in much greater depth, in natural, real-speed English.
From the Noiser podcast network. Hosted by historians, roughly 50 minutes.

Tell the life of Marie Curie in your own words, as if to someone who has never heard of her. Move through the arc: the girl barred from university in Warsaw → the Flying University and the deal with her sister → Paris, the Sorbonne and Pierre → the shed, polonium and radium → the two Nobel Prizes → the war and the "petites Curies" → the price she paid.
Combine your ideas into single flowing sentences with participle clauses ("Having…, she…", "Working…, she…", "Exposed…, she…") rather than lots of short ones, and use at least five key words from the lesson (barred, radioactivity, isolate, perseverance, frontier, benefit, double-edged sword, mobilise, toll, enduring).
Marie's greatest discovery was also a double-edged sword — it healed and it harmed, and in the end it killed her. Build an argument about scientific discoveries that come with a hidden cost. Bring in other examples you know — from medicine, energy, technology or the internet — where a breakthrough turned out to have two faces.
Tell the story of any person you admire — a scientist, an artist, an activist, someone in your own family — who pushed through real obstacles to achieve something that lasted. Use the same shape: the closed doors, the perseverance, and the legacy. Combine ideas into single flowing sentences with participle clauses ("Having struggled for years, she…", "Driven by a dream, he…").
