Tools and Books

There are many jobs we have to do, such as repairing machine where it is necessary for us to have tools. Without tools it is impossible for us to take the machine apart or put it back together again.

Repairing a machine also requires a certain degree of knowledge, so besides tools we also need books. Before taking the machine apart we should first read book about repairing machine. With the information provided by books, we should be able to do the job without difficulty.

In conclusion, tools and books are both very important when we have to do any job.
