Televisions were among the most talked-about things at CES 2013—the 2013 International Consumer Electronic Show (國際消費類電子產(chǎn)品展銷會) last week in Las Vegas, Nevada. They were bigger and better with some of the highest technology (技術(shù)). Some TVs used a new technology called OLED. They were bigger, thinner and lighter, offered better colour and were brighter than traditional TVs using LED.

Ultra High Definition TVs were also popular. Most of the TVs shown on the exhibition used 4k technology.

 Smart TVs this year were smarter. Many offered technology that users have a more personalized （個性化的）experience. One such TV from TCL can know who is watching with the help of new technology. Then it can offer programmes according to the user’s usual interest. Another TV from Panasonic offers  a similar personalized user experience.

Size also played an important part in CES 2013. TVs changed in size from big to bigger, with at least two companies —Samsung and Hisense —showing TVs that are 110 inches large on the exhibition.

The yearly CES is the biggest technology show in North America and one of the biggest in the world.

It’s a meeting of the brightest minds and the top leaders from many industries and those who want to know about the future.

Digital health and fitness inventions were also big at CES 2013. There was even a fork that tells you when you are eating too fast.

The show had over 3,200 different companies showing more than 20,000new products in about 26 miles of exhibition space.

Cyber Boy  5-26-2012  2:15 pm

Hi, I’m planning a trip to Europe this summer. I haven’t decided where to go yet, but I’d like to experience Britain and France. And I don’t want to spend too much money, Any ideas?

Esperanto  5-26-2012  2:23 pm

I had tour to Britain last year. It’s a very nice place. I had a great time there. If you get a chance, visit Stratford. That’s the town where Shakespeare lived.

Yoshi   5-26-2012  2:28 pm

First you should make sure what you want to do there. Each country in Europe has so much to see. Are you interested in museums and castles(城堡)？Or do you want to get to know anything modern?

Cyber Boy   5-26-2012  3:02 pm

Yoshi—Good question. I’d like to see some museums, but I also want to try some of France’s famous food, and a castle would also be great.

Yoshi   5-26-2012  3:21 pm

I think an English-France-Germany trip might work well for you. You can do a little bit of everything. That’s wonderful.

Esperanto  5-26-2012   3:38 pm

It’s easier to say than to do. It will need a lot of money and take time. Cyber Boy isn’t so rich. I think he’d better go in France first this time and he is still able to travel to England or Germany in the future if possible.

Yoshi   5-26-2012  3:54 pm

Esperanto—That sounds OK. But I’m not sure if he will have another trip to Europe.
