Ladies and gentlemen,
Good morning!It is an honor for me to deliver a speech:The high technology is a double-edged sword.
Technology has a big development in this years.There is no doubt that it makes us become more convenient.For example,you can communicate with others who you want wherever he or she is.Another good example is that when you want to buy something,you won't go to sulermarket,just a phone or a computer can solve your problems.
However,the high technology also caused some problems .The environment become worse.It was easy to see the pollted water.And some kids were addicted to the internet.
Just as the saying goes,every coin has two sides.It is up to us users to make good use of high technology and avoid its negative effects.Thank you.
