To be successful in a job interview, you should take care to appear modestly dressed, avoiding the extremes of too elaborate or too casual attire. On the positive side, clothes may be a good leveller, putting you on a bar with other applicants. On the other hand, clothes which are too informal may convey the impression that you are not serious about the job or that you may be casual about your work as well as your dress. Clothes which are too elaborate, too colorful, or too expensive suggest that you don’t understand what behaviour is appropriate for the job. The right clothes at the fight time, however, gain the respect of the interviewer and his confidence in your judgement. It may be not true that "clothes make the than", but the first and often lasting impression of you is determined by the clothes you wear.
Besides care for personal appearance, you should pay close attention to the manner of speaking. You should speak in a clear voice, loud enough to
A. your personal appearance
B. the way you speak
C. your self-confidence
D. the questions you ask

Information Overload

The advent of modern computers has created and duplicated vast amounts of information, and thus the problem of Information Overload appear amongst the general population.

The first thing to notice is that the media we’re all familiar with—from books to television--are one-way propositions: they push their content at us. The Web is two-way, push and pull. In finer point, it combines the one-way reach of broadcast with the two-way reciprocity (互惠) of a mid-cast. Indeed, its user can at once be a receiver and sender of broadcast—a confusing property, but mindstretching!
A second aspect of the Web is that it is the first medium that honors the notion of multiple intelligences. This past century’s concept of literacy grew out of our intense belief in text, a focus enhanced by the power of one particular technology-the typewriter. It became a great tool for writers but a terrible one for other creative activities such as sketching, painting, notating music, or even mathematics.
