Traffic lights.

The first traffic lights:
The first traffic light to regulate the auto traffic was installed in the centre of London in 1868. It was made with gas lamps.
In 1914, in the American city of Cleveland, electricity was used instead of gas lamps, because they were really dangerous.

Control of traffic:The traffic light can use two different systems to control the traffic:
- OPEN SYSTEM: this is the most simple, there is a red light in a street and a green light in another street during the same period of time.
- CLOSE SYSTEM: this is used to decrease the traffic in the busiest roads.

Traffic lights for blind people:

It is a beep which begins to sound when the green light is on.Robot and ecologist traffic lights:

They can detect some break down and call the technical service. And the future traffic light will waste less energy as it will be made with luminescent diode.


Why are the colour red and green used?

Birmingham's railway technical chose this colour in a meeting in 1841: red means "stop", yellow means "attention" and green means " free path".



A curiosity:
The Romans soldiers used a particular traffic light which made the communication between the legions in a battle easie.

Lemon tree :)

"Lemon Tree" is a song by German britpop band Fool's Garden from the album "Dish of the Day", which was released as a single in 1995 and became a major international hit in 1996.
I have chosen this song because it reminds me when a was a child, I and my best friend listened to it in my house trying to sing it.

There are some verses which I really like:

"I'm stepping around in a desert of joy
Baby anyhow I'll get another toy
And everything will happen, and you'll wonder

I wonder how I wonder why
Yesterday you told me 'bout the blue, blue sky
And all that I can see is just another lemon tree"

and I leave you the link where you can see the lyrics

Finally, a funny video of this song.

MY INTERVIEW.

Hi! My name is Celia and this is the interview which I did to my sister last week:
I did an introduction saying that she is Angela, she was thirteen years old, she lived in Granada and she was going to talk about her favourite sport, table tennis. Then, I started with the questions:
I asked her how she had begun in that special sport, and she said to me that she had begun because her father really liked that sport and he had opened a school of table tennis seven years ago.

The second question I wanted to know was what the most important competition that she had won was. She said that the most important competition was when she had won the Table Tennis Spain Tournament a year before because she had to train really hard.

And the last question I asked her was if she could play other sports, which one it would be. She said that she loved football and she played it really well, so she would play football if she could.

I couldn't ask more questions because she had to pack her suitcase and to be concentrated because that day she had an important tournament in Valladolid.
