完形填空

Wearable gadgets (可穿戴设备) are usually high-tech equipment, which are so small that people can wear on heads or wrists.

Google Glasses is such kind of wearable gadget. It has attracted the world’s attention since being tested this year. Users can take videos and broadcast live on the Internet. There is also a GPS system in the glasses. So if you get lost you can say “OK,Glasses, where am I?” Then it will tell you where you need to go. It sounds cool, doesn’t it?

Don’t forget Galaxy Gear from Samsung, a Korea company. It is just the tip of the iceberg. This smartwatch looks like a normal watch but much lighter. But Galaxy Gear needs to connect with a Samsung smartphone or tablet (平板电脑). Its short battery life of 25 hours also disappoints (使…失望) users.

With all kinds of wearable gadgets coming into real life, it seems that wearable technology is becoming more modern and popular. Indeed, unlike smartphones, wearable gadgets are more convenient (方便的). Their biggest advantage is that they can do most of the same things as smartphones, yet they are hands-free.

However, wearable gadgets also have their own problems. Some people are not sure whether wearing a gadget is cool. Unless you know about it, you may just think there are many crazy people talking to their wrists.

Perhaps only time will tell how these gadgets will change our lives.
