A mum saved her daughter’s life with her newly learned first aid skills. Sonya Hall, 33, of Denny Avenue, Lancaster, had only just attended one first aid class the day before when she found herself needing to use the skills on her three year old daughter Tilly.
Sonya, who also has son Emmen, six, attended the first aid course at Lune Park Children’s Centre in Lancaster. Then she was faced with every parent’s worst nightmare when Tilly went blue in the face and stopped breathing. But thanks to her newly acquired skills, Sonya saved Tilly’s life.
Sonya said: “Tilly was playing with her brother and they were fighting over a toy. Emmen won the fight. Tilly fell backwards and her head was hit. She was face down and shaking and at first I thought she was upset. But then I saw she was blue in the face and had stopped breathing. I reacted without thinking and immediately started using the first aid skills I had learned the day before which were so fresh in my mind. I began doing mouth-to-mouth and chest compressions (胸外按压). It probably took about a minute before Tilly started breathing again, but to me it felt like a lifetime.”
After getting Tilly breathing again, Sonya called an ambulance and the doctors came. Since then, Tilly has been diagnosed (诊断) with Reflex Anoxic Seizure (反射缺氧发作). Sonya said: “The seizure can happen when there’s any unexpected pain, fear or fright. It is just so lucky that the day before it happened, I had been practising first aid.”
The Empowering Parents First Aid course is run by Lancashire Adult Learning. Sonya said: “I am just so glad I did the course and learnt the first aid skills. I always feared I would not know what to do in a crisis situation, but luckily I had the knowledge and skills to deal with it.”

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!
