1,6+(5+3,4)= (1,6+3,4)+5= 5+5= 10

2

0,3+(1,7+2,5)= (1,7+0,3)+2,5=2+2,5= 4,5

(3,8+6)+4,2= (3,8+4,2)+6= 8+6= 14

PHONES IN FASHION.
The necessity for telephone is unquestionable; they have become since the 1950s, an essential tool in modern life. One may argue if a ‘real need’ exists for people to use their phones as often as they do, but can you imagine your life without one at home, or even in your car, or when on holiday in the mountains?
1.-------------. In recent years mobile phones have become fashionable. Technically called cellular phones, they’re one of the great contributions of technology to our lives.2.--------------. Calls can now be made from far away areas of the world thanks to a vast web of microwave transmission towers, antennas, and satellites in space that took years to develop and build. The most basic car phones in use today allow businesspeople to remain within their officers’ reach, and drivers to travel alone safely. Smaller and lighter models now allow users to take their telephones almost everywhere, including the beach, their weekend home, and even some aeroplanes.3.--------------------.
Nowadays, the cellular phone has become a status symbol, without which in some cultures it’s assumed you belong to a ‘lower class’ of ‘ less successful’ people.4.---------------. It’s simply a way of showing off and making oneself look important to others.
Obviously, mobile phones are convenient but this convenience also has its price. 5.--------------------- . On average, cellular phone calls are about twice as expensive as those from regular phones and additionally, you have to pay a monthly fee to use your phone.
(Adapted from The World Of English)








a). Even schoolchildren now have the opportunity to contact their parents or friends over their own mobile phones directly from the school premises.
b). Although today’s cellular telephones are much cheaper than the first model available, they still remain more expensive to buy and use than regular telephones.
c). Hardly anybody would give a positive answer to this question.
d). Although it’s taken a long time to make them available to everybody, it’s now clear that they enable us to communicate with the most distant places.
e). Yet, it’s often amusing to hear such ‘successful’ people using their phones to call friends from bars and restaurants when cheaper public payphones are nearby.
f). Still, mobile phones may not be long before the cellular phone is as basic as a calculator in the lives of many people around the world.
