Storm chasers North America is famous for its wide open spaces, and this landscape can cause some very exciting weather. In fact, the USA has more tornadoes than any other country- there are about 1,200 every year in a part of the country called "Tomado Alley'. This is in the centre, from North Dakota in the north to Texas and Louisiana in the south. (1___) They are just normal people, but their favourite activity is following storms and getting as close as possible to a tornado! We call these people 'storm chasers', and it's quite easy to become a storm chaser these days. (2___) Gabe Matthews is a storm chaser, and he follows the weather as often as possible. 'Seeing a powerful tornado is an amazing experience,' says Gabe, but it isn't easy to be in the right place at the right time. My friends and I need to do a lot of work to find a tomado and get to it. (3___) Then we have to wait for ages before we see the weather changing. But when that starts to happen, it's so exciting. Many people become storm chasers because they like the danger. But Gabe is always very careful. He tries to get close to the centre of the tornado, but not too close. 'Once I saw cars flying through the air,' says Gabe, 'and a big American truck! (4__)* You don't want those cars to hit you!' Another reason people chase storms is to film them. A news channel recently used one of Gabe's films. That film was exciting because it was a strong storm and it caused a lot of damage. It was great to get it on TV. However, Gabe was even prouder of something else that he did. 'My friends and I heard screams when we were filming.(5___)
They couldn't get out, so they were very relieved when we rescued them. It was great to help people like that.' Perhaps you have to be a little crazy to be a storm chaser. Certainly, some people say that storm chasers just want to do something thrilling, But they're often the first on the scene, giving important information to the rescue services. So actually they often save lives.
A When we know that a big tornado is coming, we have to drive a long way.

B All you need is a mobile phone, a good car and GPS.

C He wasn't very happy when he had to go to hospital.

D The weather is changing in all parts of the world.

E That was really exciting, but we watched it from far enough away.

F It's also in this area that there are hundreds of people studying the weather.

G We followed the sound and found some people inside a building.
