Depending on personal experience, personality type and emotion concern, I find some people like doing work by hand while others prefer using machines. From my point of view, I prefer to use machines rather than doing work by hand, because machines are more efficient, more precise, more clever.  

Machines are efficient. They can repeat the same task repeatedly without tiring. Before the industrial revolution, farmer had to reap the corn by hand, this work is very hard and cost people much time, but by using reaper, farmer can reap the corn in a little time. Another example, do you like to wash clothes by hand or using washing machines? Of course, I choose using washing machines, for washing machines can wash clothes very clean and fast. Machines improve our work efficiency greatly.  

At the same time, machines can be very precise. Before the computer invented, I had to do some calculation by hand and often made many mistakes, but now I can depend on the computer to do the same task, more precisely and faster. I cannot imagine doing the same task by hand now.  

Machines are also very clever. When I use Word processor to type a paper, the computer can always find some spelling mistakes automatically and provide some possible choices. It facilitates my work considerably. In addition, I think machines are gradually changing everyone`s working pattern.  

Of course, some work has to be finished by hand, but if there is any possibility, I will use machines to do my work without hesitation.
