Good morning everyone!Today I'm going to talk about inventions．
Inventions are created every day because people would like to make life easier．There are famous
inventions like TV and the bicycle．TV provides us with different kinds of information so that we can know more about the world．We watch entertainment programs to relax ourselves．Besides，some learning
programs help us with our study．
The bicycle is very useful，too．We go to school or work by bike．It makes no pollution，which is good for our environment．What's more，bicycle riding is quite good for our health．It's cheap，too．
Though there have been many great inventions．I wish to invent a kind of pen to help us write more
quickly and neatly．When we have problems in doing homework，it will tell us how to solve them．
That's all．Thank you very much．
