Dear Dean,
It is my understanding that this college has received a large donation to be used to improve the quality of life for students: expand the bookstore or add computers to the lab. I strongly argue in favor of the addition of more computers.
We have to think about a greater goal and a more practical way to enhance the quality of life for students. Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can research in their field using the best tools provided by technology?
As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future, since many students will be expected to be familiar with the latest software and other tools when they go on to work.
While they are in college, students find they are expected to use computers. They are asked to create PowerPoint presentations and research many topics on the Internet. Being able to do projects using the computer also gives students the opportunity to find information that without a computer would be much more difficult to find. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage.
If there are more new and faster computers accessible, students will be able to complete their work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and computer. No longer will they have to sit and wait while an outdated computer struggles to follow their commands.
The more computers are used in society, the more colleges will depend on them as a tool of teaching and learning. Making computers more accessible to students facilitates their learning process by making it much easier and more engaging(专注), and eventually improves their quality of life.

Being able to multitask---doing several things at the same time---is considered a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.

What we often see nowadays is that young people juggle an ever larger number of electronic devices as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a significant amount of time in fruitless efforts as they multitask.

Multitasking is even changing the relationship between family members. As young people give so much attention to their own worlds, they seem to have no time to spend with the other people around them. They can no longer greet family members when they enter the house, nor can they eat at the family table.

Multitasking also affects young people’s performance at university and in the workplace. When asked about their opinion of the effect of modern gadgets on their performance of tasks, many young people gave a positive response. However, the response from the worlds of education and business was not quite as positive.

Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary for them to learn special skills to do their work.
