Across the world, especially the wealthier parts, the mobile phone has taken the place of telephone as an electronic telecommunication device, with the majority of the adult, teenager and even child owning one. As this technology has become rife, its drawbacks, which can be seen from social, medical and technical perspectives, deserve people's greatest attention.
Similar to many other hi-tech products, such as computers, mobile phones have detrimental effects on users' health. For example, long-time heavy phone users seem to be more prone to certain types of cancers, although evidence to date is inconclusive. Another lethal health concern is the link between mobile phones and road accidents. It is argued that motorists have a much higher risk of collisions and losing control of the vehicle when driving and talking on the phone simultaneously, despite sometimes using bands-free systems.
When the mobile phone has brought considerable convenience， people's obsession with convenience has meanwhile caused enormous disturbance. That's why the use of mobile phones has been prohibited in many public places, such as libraries, theatres, hospitals and even transports, such as trains, buses and aircrafts. Speaking at increased volume is considered impolite or even offensive, In schools, students are required to switch off cell phones before the class begins because mobile phones are responsible for a high amount of class disruptions.
When its downside persists, the mobile phone has proven indispensable in modern life. It is handheld, lightweight, portable and multi-functioned, allowing users to send text messages, exchange music files, make voice calls, browse Internet, and so forth. Meanwhile, within twenty years, mobile phones are expected to be more pervasive as technical advances and mass manufacture will make them low-cost personal items. Given those factors, the mobile phone will continue to perform its role as a key social tool, by which one keeps in touch with others much more easily than did the generations before.
As suggested above, the contribution of the mobile phone to the society is prominent and people's dependence on it for communication is an irreversible trend, although it has a number of problems that should be well handled.

Laptop computers are popular all over the world. People use them everywhere. They connect people to their work place. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program allowing students to study schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are a part of a $10 million computer program at Westlake. Students with laptops will also have access to the Internet.In addition, they will be able to use e-mail to “speak” with their teachers, classmates, or families.However, the most important part of the program is that students will be able to use computers without going to computer labs. They can work with it anywhere they like!
Because of the many changes in computer technology, laptop use in higher education is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, portable computers can connect students to not only the Internet, but also libraries and other resources. State higher education officials are studying how laptops can help students.
At Westlake College, more than 60 percent of the staff uses the computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”

The Bad Influence on Children Brought by Modern Science and Technology
If we depend on modern technology too much, it will bring bad effects especially to children.
During the growth of children, basic education is essential. Computers and scientific tools should not replace school education. Through systematic study in school, children can oversimplify the life. In this way, children will become very lazy and unwilling to use their mind.

For instance, losing hair, not sleeping very wett and having a headache, etc. The biggest harm to children is that staring at the compurer for a tong time will damage the vision. So the children have to wear a pair of glasses early from their school days. It will do harm to the whole process of their growth.
This kind of dependence on computer atso can arise the dependence on their parents in life. If they do their homework with easy tools, how can they do their own businesses through themselves?

现代科技在给人们带来便捷的同时，也带来一些不良影响，尤其是孩子。作者举了两个例子说明孩子过分依赖于电脑的后果，令人担忧。其实这种担忧似乎有些片面，只能看作一家之言。

现代科技带给儿童的不良影响
如果过分依赖于现代科技，那么它就会给我们，尤其是我们的孩子带来不良影响。
在孩子的成长期间，基础教育至关重要。计算机和科学工具不应取代学校教育。通过在学校的系统学习，孩子们都能学会如何学习，如何创造和如何做人。但是通过电脑孩子们只能学会如何简化生活。这样一来，他们就会变得很懒惰并且不愿动脑。
除此之外，在电脑前停留时间过长不利于孩子们的健康。电脑射线会引起许多不适的感觉。例如：脱发、睡眠不良和头痒等等。最大的不利就是损伤视力。因此，有些孩子不得不从上小学就带眼镜。这对他们的成长是有害的。这种对电脑的依赖也会导致他们在生活上对父母的依赖。如果他们仅会用简单的工具来做他们枯燥的作业，那么他们怎么能独自做事?他们可能只是坐在电脑前，一动不动地要这要那，同时减少他们的身体锻炼。
因此，现在是限制他们坏习惯的时候了。这不仅仅是为了他们，而且是为了整个国家的进步，应该发展他们的头脑。孩子们应该通过自身的努力来取得成功。
This simple picture represents a situation that every person must face: when approaching ajunction, which direction should one choose?
Most viewers can empathize with the sense of hesitation and uncertainty embodied insuch an image. Without exception, everyone has to make choices in life, whether they concernschool, career, or love. While some choices are simple, one cannot avoid the task of makingdifficult decisions.
Choices are often directly related to one’s happiness. University students,for example, facea hard and crucial decision upon graduating. Many students have difficulty deciding whether tocontinue studying or begin developing a career. Every individual is different, and one must takethe factors of one’s personal life into consideration. In addition to an awareness of specificcircumstances, however, making the right choice also depends on correct appraisal of oneself.
In order to choose correctly, therefore, one must be both realistic and self aware.Furthermore, once having made a decision, one should seriously accept and pursue the pathone has chosen, and strive towards the realization of one’s goal with spirit.
Young People Should Have Ideals
What are you going to do when you grow up? When I was a child, people often asked me this question about the ideal. Undoubtedly, every individual, especially a young person, should have an ideal. Hardly can we find any great people we know ideal when they were young.
An ideal is a vital importance to one's growth and success. On the one hand, an ideal is the target of one's life. Once you decide what your ideal is, you know where to go, and which way to take. Otherwise, you might become puzzled in many things in your life. On the other hand, an ideal is like the engine of vehicles. Only when we have our own ideals, can we find the origin of energy and enthusiasm in life, and become active and perseverant. Whatever your ideal is, careful plan and preparation is vital to its realization. Of course, the path from where you are to where you want to get is not always smooth and straight. Therefore, an optimistic, positive mind is indispensable in the process of your persevering your ideal.
In a word, only if you have an ideal, you will have the chance of realizing it.
