First draft- conclusion

 In conclusion, we can't deny that computer is an astonished invention. It makes people evolved rapidly and make our works easier and comfortable. It has both of negative and positive effects. But computer has more positive effects than negative effects. Also If people have a wiil to remove the negative effects, people can do it. Because people have an ability to solve some problems. So I assert that computer is very good and useful tool and we should reject to use computer, but we should encourage to use it
