were hiking in the mountains when lightning flashed
across the sky. The sky got darker and darker. And
then we realized that we weren’t looking at clouds. It
was smoke! There was a wildfire!
Last winter, my family had a terrifying experience. It
started one evening while we were enjoying a quiet night at home. My parents were watching TV while my brother was doing his homework. I, on the other hand, was glued to my bedroom window. Thick snow was falling and the world outside was growing whiter and whiter.

getting closer yet, but let’s keep moving until we see the
water!”
A: My brother suddenly pointed ahead. “I see the lake! Look!”
B: I took a deep breath and said, “Sorry, I wanted to take photos...
I won’t do that again in danger.”

During a storm, storm chasers put special equipment in the way of the tornado. The equipment collects information about things such as wind speed and air pressure. This helps scientists to make better forecasts. It can even help people understand how powerful the winds can be, and as a result, change how we build our houses.

Storm chasing can be exciting, but also very dangerous. The storm chasers’ knowledge and experience are not always enough to keep them safe.

It grew rapidly and changed its speed and direction.

All three men in the car died.

1. What do you think of Tim Samaras’s job as a storm chaser
2. What do you need to be a good storm chaser
3. Do you know of any other dangerous jobs Why do people do them
I think his job is exciting, but also very dangerous.
To be a good storm chaser I need to have a lot of knowledge about weather science, know how to use special equipment, and always be prepared for danger.
Yes, like firefighters or deep-sea fishermen. These jobs are dangerous because they involve risks like fires, high waves, or bad weather. People do them because they want to protect others or because they want to support their families.
