What do we want a clock for?
When we are playing computer, we know the time by looking at the bottom-right corner;
If there is no computer, you may have a telephone in your room, it should also show you the right time;
Watching television can also let you know the time;
Of course, nowadays, anybody has a cell phones. Look at the mobile phone, and it is very convenient;
In your kitchen, your cooker may have a timer, or the boiler timer also displays the time;
If you go out, you may forget bringing your mobile phone with you, or have it in you pocket, but the battery is gone, you can look around to see a Big Ben on the church tower;
If you can't find one, or there is a big ben, but the hands always point to half past six PM, but you know that's wrong, because you just had your lunch, then you can ask a passer-by;
If you don't bother asking, or tried one, but she hasn't a watch, same as you do, then go to a store to buy chewing gum, the time you need to know is printed on the shopping receipts.
A clock without hands
When my friend Lee returned to China, he left me many things which he could take back with him, includes one alarm clock.
One day I suddenly discovered that the clock hands were all gone, a clock without hands!
My naughty daughter opened the lid, pulling out all the hands.
But the clock can still "Tick-Tock". It's working.
