Everywhere I go, people are speaking on their cell telephones regardless of their surroundings (环境) . This happens when people are walking around a lake or through town, or even driving. I have even seen a person attempting to speak on her cell phone while ordering ice cream at Dairy Queen, thus speaking to two people at once.

As the over-spending of technology increases, people begin to take less joy in the simple pleasures of life—joys that don’t cost money—from observing clouds, playing with children to thinking or reading. And it is not just telephones that take the responsibility; too much value is placed on items (物品) from computers to cars. Many things are purchased (购买) merely(仅仅) to show off. Do you really need a cell phone that plays games, shows movies and takes pictures? No, cell phones should be purchased to use in urgent situations.You do not need to use your telephone when you are at someone else’s house or in a restaurant.

Technology and possessions (财产) do not bring joy. While some technology is necessary, it can get ridiculous(可笑的). Each possession just makes us want more, while simple pleasures can be enjoyed now and then.

Instead of spending our time buying a third television or looking into the newest cell phone models, we should be acting more productively to improve the world by volunteering, for example. Or, we should reconsider playing computer games or taking pictures on our cell phones and read a book or imagine what shapes the clouds are in the sky instead.

A.focus on technology and their belongings.

B.use cell phones in less urgent situations.

A.people have no time to play with their children.
