Today, with the development of high-technology, we can get access to all kinds of high-tech products, such as computer, digital cameras and so on. These products make our life more convenient, we can keep in touch with family and friends any time any where. Our life has been changed by the high-tech, we live in a fast-pace world. Cell phone influences our life deeply, everyone owns it. While cell phone brings many dangers. First, cell hone contains radiation which hurts people’s body.
Today, more and more people die of cancer, the main reason is that the high-tech products radiate their bodies, in the long run, the bodies get sick. Cell phone is one of such products, it hurts our bodies as long we use it. Second, cell phone distracts our attention about discovering the beauty of life. People pay their attention on cell phone, they count on it by reading news and making friends, being less going out. We should use cell phone properly.
It is often said that smartphones have made our lives easier. Thanks to these handy devices, we can take our work with us anywhere. However, this isn’t necessarily a good thing.
A recent survey found that two-thirds of office workers continued to work on their smartphones outside office hours. These so-called “screen slaves” are glued to their smartphones on the way home and at home. This can lead to health problems. For example, using a smartphone on the train or sofa can cause back and neck pain. What’s more, looking at a small screen for a long time can cause vision problems.
In Taiwan, there was even a man who lost the use of his index finger because he played games on his smartphone for up to six hours a day. People who use their smartphones too often also complain of headaches, increased stress, and losing sleep at night. So perhaps we need to learn to be less dependent on our smartphones, and put them down once in a while.
Mobile phones are the main invention of modern technology.They are completely part of our daily lives If we look at our society,we can see that all kinds of people are using mobile phones.Maybe they have many advantages,but they also experience drawbacks.
The main advantage of mobile phones is that people can use them anytime and anywhere,so they can use one for an emergency.in addition,people can access the internet whenever they use the mobile phones,so business people can use tem at work to get information from internet more convenietly Moreover,it is very easy to send messages to your friends.Mobile phones can make people keep intimacy in spite of long distance.Mobile phones are turning the world into a small vilage where we can commmunicate with each other easily and simply.Finally,another point in favour of mobile phonesis that you can avoid disturbing anyone when he is sleeping orworking because in that case people often turn off their mobile phones.
On the other hand,there are some drawbacks,too.Firstly,the most important disadvantage is the unknown effects on health in case of over-use.Scientists found that mobile phones can cause brain cancer.if you talk for so many hours,you are going to have headacheand ear problems.Secondly,the mobile phone stimulate home for the high cost of communication.If you are in 3 membered family,you would spend a lot of money on mobile phone.Because tow to three of family have it, it cost about 150-200D in a month.Furthermore,the inappropriate use of mobile phones could be bothersome.for example,it is very imppropriate to here a mobile phone ringing during a formal conversation,during a lesson,in a libraryor in a cinema.Finally,mobile phones waste people too much time.An Amerian survey show that the teen-ager will spend average 2 hours to send messagesevery day.
In conclusion, there are some benefits and drawbacks to mobile phones.personally,i dont like mobile phonesvery much,but i need use them.In my opion, mobile phones are good only if you use them correctly and politely,as in this case,all technology is beneficial!
Recently,short messages become more and more popular with both the young and the old.People accept the convenient way of communication and some even cannot live without them.
As to the easons why so many people are in favour of the short messages,in my opinion,there're three points.First, it can save time if you want to inform your friends of something in one or two words by sending a short message.By comparison with letters or email,short messages are really more quick for others to receive you as the mobile phones are always with them.Second,short messages cost less than making a phone call.Third,people who are not very familiar with each other can chat by short messages more easily,through which more and more people can know of others and become friends.
However,nothing that is perfect exists in the world.Short messages also have some disadvantages with them.Some people cheat or fool others by telling them that they have won some prizes through short messages.Also,taking advantage of people's ignorance,some websites charge a good deal of expenses form short messages.
Above all,short message is product of the hitech nowadays.It will serve us very well if we make proper and full use of it.
Nowadays, with the development of high technology, smart phone is very popular among the high school students. The smart phone once was thought to be forbidden using in the class, now has become very common tool for students. A lot of students keep their eyes on the phone all the time, even in the class, they still check on it.
Teachers are upset about this situation, because they feel most students ignoring them when they are passing the knowledge. Some teacher think it is time to let the students hand in their smart phones in the class and after class, these communicational tool will be turned back. I don’t think it is a good idea. Even for the teachers, they count on their phones so much, let alone for the students. The teachers should improve their teaching method to catch the students’ interest.
