10 Read the blog posts about people's opinions of technology. Match the comments (1-6) with the people
(A-DI. You can use the people more than once.
A
I think the technology we've got available in our lives today is amazing and I can't imagine what life was like in the past without it. Technology has come a long way in recent years and it's changed our lives in so many ways - it's given us freedom and independence! We can book a holiday, we can work or study at home, we can do housework faster, we can interact with our friends and even watch films and TV while we're traveling! Not only that, but now we don't have to leave home to do things that used to take a lot of time. We just touch a key on our computer and order a meal or book a train! In general, i'm a fan!
B
I'm not sure that all these changes in our lives because of technology are positive ones. Now, because we can get all this information so quickly, we're expected to do things faster and faster. Something that might have taken days to do in the past, like researching a project, can be done in minutes on the Internet. That means expectations have gone up about how much people can do in the time they've got. Now you have to be able to do ten things a day instead of two and to think and act faster than ever before. Sometimes it can be stressful.
C
There isn't often much time to relax and be quiet - to just switch off - because people can contact you at any time. With email, social networking and text messaging all available on our smartphones, we're constantly connected. There are times when that's good. It's great when friends get in touch, or when you need to check the time of a bus or train quickly.
However, most times it's work, or people you don't want to talk to that contact you. We're always receiving advertisements by email and being called by people trying to sell us things.
D
I moved to Australia with my family last year and technology has really helped me to stay in contact with all my friends and relatives back in England. I was lonely when we first came to Melbourne but now I use video chat and instant messaging to talk to them almost every day and we can share photos and videos too. I feel that we're still connected and they always know what's happening in my life. We live in different continents but technology means that we can easily bridge the distance in the virtual world!
It can be a disadvantage that we are constantly connected to everyone.
Technology helped me to socialise with people I don't see often.
Technology has created more work for us, not less
There are definitely more advantages than disadvantages.
Technology means we're not dependent on other people to do things.
It's stressful that everything is faster nowadays.
