Mobile phone is AN invention OF THE twentieth century, which 'revolute'? telephones sphere. It's THE wireless phone, which HAS changeD for couple of years since THE beginNING OF THE mobile phones invention. Not only in appearance (it's smaller), but in 'employ'(usage, facilities,?) too.
Firstly ANYONE who has a mobile phone can 'be always keep' ALWAYS KEEP in touch all THE time, because thESE phones are wireless. When we have a situation, when
somebody needs 'to be helped' (mozna tez needs help), we can ring (kogo?).
The newest mobile phones serve not only for ringing but THEY haVE access to THE internet, THEY take photos etc.
In contrast it's not 'cultured' GOOD MANNERS when WE ARE in A public place TO HAVE THE telephone ringing. It's expensive to keep.
When we are talking THE phone is emitting radiation, so it's
A menace to 'live' LIFE (rzeczownik).
In conclusion, I want to express 'oneself'MY OWN THOUGHTS about mobile phones. I think that people need 'it' THEM (dlatego ze phones to l. mnoga), but within limits.
But ONLY WHEN it's needED in pressing situations or when somebody needs to be helped.
