Объяснение:couldn't imagine my life without my phone or i should say phones because i've got a mobile, too. i need a telephone to get in touch with my friends or to call the police or an ambulance. it is almost impossible for me to live without my phones. at home i've got a cordless telephone, i think it saves time when you have a receiver just at hand. but my mum was against buying a cordless phone because if there is some problem with electricity it wouldn't work and you'll be totally lost. she also thinks that it is a luxury to have a mobile, it is too expensive, it is more trouble than it's worth. besides she says that mobiles are dangerous for health. the rays may cause headaches and even more dan¬gerous diseases. i don't believe her. for me my telephones are really invaluable.
