2、美文背诵

科学技术在日新月异地发展，它们在人们生活中的应用越来越广泛，但是也带来了一些问题。结合生活实际，谈谈科学技术给人们造成的影响。

In our everyday life, we can see the following scene: in the past whenever the father came back home, his wife would bring him a cup of hot coffee and his little son and daughter would happily greet him with “Daddy”, all excited at his return.What a warm family!

But now,with the development of technology, everything has changed. Upon entering the house, the father always finds his son addicted to playing computer games and his daughter phoning her friends and his wife absorbed in watching TV series.Nobody takes notice of his return. As for himself, he is also busy dealing with his own business with a cell phone.

All these reflect a serious phenomenon that the wide use of technology is beginning to influence the relationship between family members, who seem to have no time communicating with each other.As a result, there tend to be misunderstandings between family members. So we shouldn’t have the advanced technology affecting our family life.Most importantly, we should be the master instead of the servant of the advanced technology./We should make use of the advanced technology wisely so as not to be controlled by it.
