in my opinion, using the conputer as your hobby can be harmful to both your health and your social life. firstly, sitting all day in front of the computer can cause health problems such as eye-tiredness and obesity. secondly, you may get irritated easily. besides, if you use she computer too much, you will not have time for our family and friends. in short, computers should only be used to for a limited time. 1. using the computer too much can make your eyes tired 1........t........... 2. using the computer too much is not good for you 2.........t.......... 3. we still can spend a lot of time with our family and friends 3.......f............ 4. according to the write, we can use the computer for a long time 4. .......f.......... 5. computers should only be used for a limited time 5...........t.........
