I always knew that I depended way too much on my phone.     I didn’t know how much, so I decided to do this challenge to find out.

Every morning since I got a smartphone, I’ve used The Weather Channel App to find out what to     . On the first morning I had to dress without guidance, but     I was able to guess that the day would be cold and foggy by looking out of my window.

I couldn’t tell what time it was. I haven’t worn a     for more than a year, because my phone showed the time. So I was late for     friends who had been on the bus for two hours from Santa Monica to Palos Verdes. I was also late for my part-time job. And     , I couldn’t call people to tell them that I was running late.

Getting places was harder, too. I got      because I couldn’t use the GPS (汽车导航系统) on my phone. My driving, though, got a lot     because I no longer had my phone in one hand checking directions while     with the other.

But the number one trouble was not having my contact list (联络簿). I forgot to write down my friends’ and family members’ phone numbers before I     the challenge. It was sad to realize that I couldn’t     my brother’s and my mom’s cell phone numbers. Oh, how I wished to turn on the phone for just a second to look up phone numbers!

Even with all the problems, however, I found     not worrying about missing a text message or an e-mail.

This     was a great learning experience. It surprised me how I’d taken no notice of even the     things like remembering phone numbers. We all should take some time to think about how we can depend     on our cell phones.
