Read the text and mark the sentences T (true) or F (false).
In the United States there’s a burglary almost every fifteen seconds, especially during the day when people aren’t at home. But don’t be afraid. There are a lot of things you can do to protect your house from burglars.
First of all, you shouldn’t let people you don’t know into your home. You should always look
through the peephole before you open the door. It’s also a bad idea to leave money, jewellery or keys next to windows. Always lock all doors and windows when you leave the house, and if possible, install an alarm system and check it often to make sure it works properly.
Another way to protect your home is to make it look busy all the time. Leave the radio on when you are away and fit dusk-to-dawn lights in the garden. That way, anyone watching the house will think that someone is there.
Finally, join a Neighborhood Watch programme and call the police the moment you see something unusual in your neighborhood. And remember: never put up a fight with a burglar. Just hand over your valuables and then call the police. It’s better to be safe than sorry.
