make sure your spelling is correct
Yes, if you use Microsoft Word as your word proc. program or if you use Firefox as your web browser, you will have a built in spell checker function. So, use the technology to get the spelling correct.
I'll correct the rest:
Personally, I believe that television is the fantastic invention in 20th century for its advantages.
In These days, one can stay at home and watch what happens in the different parts of the world with the vivid image and exciting sound. ---- very good!
In addition, we can relax after the hours at the workplace and enjoy a wide range of channels and attractive shows on TV.
Nevertheless, many recent research studies point out the negative effects of television. Kids,as the typical example, who switch on television, very soon may have the aggressive behaviors if they watch inappropriate programs, for instance, violent films or game shows.--- I don't know if game shows make people aggressive!!
I think you are trying to say 'explosion' instead of bomb:
As far as I am concerned, television influences people more than other forms of media. With the
bomb explosion in technology development, humans can find many other tool to communicate, but television still has the strongest effects.
for the next long time.
