IS TECHNOLOGY ALWAYS BEST?
0 ..as.In my opinion, technological advances are not always as such a great
00 ..x.. advantage. It is true that new forms of communication bring benefits,
1 …… especially if you have some research even to do for a school assignment,
2 …… or if you need to get in touch them with someone urgently. I am not so
3 …… convinced, however, that they are actually have such a positive effect on
4 …….. people of my generation. Like so many the teenagers in this country, I find
5 …… that I use my mobile phone a great deal, and if I do write to someone,
6 ……. it's usually a quick e-mail. It was when my girlfriend actually took up the
7 ……. trouble to write me a long letter that I stopped to think about it what I
8 ……. was doing. She said a lot of nice things in that letter. It was written on
9 ……. classy paper and she had taken there a lot of care about her handwriting.
10 ….. Although I'm not a great romantic, I'm sure it's something I'm always
11 ….. going to treasure. But she also said a few of hard things which made me
12 …… to think. Can it be true that I'm more interested in chatting with complete
13 …… strangers online than I am in talking to her face to face? And she was
14 ….exaggerating when she said we never get rather more than five minutes alone
15 ……. together without that one of my gadgets buzzing or bleeping, wasn't she?
