Salut,

J'ai fait un petit résumé d'un article, j'aimerai savoir si vous y voyez quelques fautes, merci.

For years gangs of youths have been free to roam the country’s shopping streets. So the ASBO created a high-frequency ultrasonic sound called the Mosquito : this sound is inaudible to anyone aged over 25 but intolerable to anyone under that age.

A lot of Mosquitos have been sold to some business establishments and local authorities to move on troublesome groups of youths.
As soon as the Mosquito goes in, people feel more comfortable going into the shop because there are no kids hanging around.

The Mosquito is supplied with a warning sign alert, but some parents are annoyed that some shops are testing the device without giving any warning. They worry about how this sound affect babies and children.

Finally, more and more establishments like railway companies, the Metropolitan Police, colleges and schools are using this system.
