A．Distinguished professors at research universities should focus on research only.

a mystery. All we really know is that—men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken, or written in letters we call words.

The power of words, then, lies in their associations—the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of word that mean something to us increase.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar.

As we know, it is very important that a fine should pay attention to the training of its staff as there exist many weak parts in its various departments. Staff training must have a purpose, which is defined when a firm considers its training needs, which are in turn based on job descriptions and job specifications. A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behavior, knowledge and skills that are expected of an employee who works in it. When all of this has been collected, it is possible to make a training specification. This specifies what the Training Department must teach for the successful performance of the job, and also the best methods to use in the training period.

There are many different training methods, and there are advantages and disadvantages of all of them. Successful training programs depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place "off the job" in the classroom, but training in using these skills takes "on the job", by means of such activities as practice in the workshop.

It is always difficult to evaluate the costs and savings of a training program. The success of such a program depends not only on the methods used but also on the quality of the staff who do the training. A company can often check on savings in time and cost by examining the work performed by the workers and technicians who have completed a training program. The evaluation management training is much more complex than that.

To be successful in our training programs, we must understand the difference between______.

A．a job description and a job specification

B．what is taught and how it is taught

C．learning about skills and training in using them

D．the savings in time and the savings in cost

A．it was necessary to combine truth and fiction

SECTION B PASSAGES

Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.

听力原文： Today we're going to evaluate the main tool used when addressing groups the voice. There are three main elements that combine to create either a positive or negative experience for listeners. They can result in a voice that is pleasing to listen to and can be used effectively. Or they can create a voice that doesn't hold attention, or even worse, causes an adverse reaction.

The three elements are volume, pitch, and pace; When evaluating volume, keep in mind that a good speaker will adjust to the size of both the room and the audience. Of course, with an amplifying device like a microphone, the speaker can use a natural tone. But speakers should not be dependent on microphones—a good speaker can speak loudly without shouting.

The second element, pitch, is related to the highness or lowness of the sounds. High pitches are, for most people, more difficult to listen to, so in general speakers should use the lower registers of their voice. During a presentation, it's important to vary pitch to some extent in order to maintain interest.

Pace, that is how fast or slow words and sounds are articulated, should also be varied. A slower pace can be used to emphasize important points. Note that the time spent not speaking can be meaningful, too. Pauses ought to be used to signal transitions or create anticipation. Pauses can be very effective when moving from one topic to another.

What's the main point the speaker makes？

A．Content of speech is more important than tone of voices.

B．Voice quality has a strong effect on listeners.

C．Effective speakers must use visual aids.

D．Amplifying devices are essential in large rooms.
