Just the mention of the TOEFL, GRE and GAMT exams brings a thought of long hours of dull paper work. But that idea is becoming increasingly out of date. As planned, computerized tests will begin next year which will bring a series of changes from test psychology to scoring techniques.

From computer - equipped rooms, examinees will answer the questions on a computer. If they are sure about their choices, they can pass to the next question by pressing the entry (条目) “next”. Then another question will be randomly (任意地) selected from a vast test item bank and appear on the screen. After answering all the questions, examinees can choose the entry “quit” if they are not satisfied with their performance, or “score” if they want to see the result. Scores will be calculated immediately and appear on the screen. By that point, student's marks are official--there is no going back.

Since they greatly shorten the painful waiting process-which used to be two or three months, computerized tests have won worldwide popularity. Besides, there will be no rushing to the registration offices (登记处) for these exams. Computerized tests will be given every workday in an exam center with all three kinds of tests being held in the same room. All test takers need to do is to call the exam center and book their seats for a particular day.

In addition it will become technically possible to apply new testing procedures. In the past, each examinee had the same set of test items despite differences in their ability. Under a computerized system, however, if the computer judges an answer is right, a question of a relatively difficult nature will follow. But if an examinee continues to give wrong answers and is judged as un-qualified by the computer system, he will be automatically denied the chance to go further in the test.

小题1: Computerized tests allow the examinee to know their scores ______.

A．immediately on a central computer for scoring test papers

B．a few minutes after the exam with the help of a test center worker

C．on the next day after they have taken the exam

D．immediately after the exam by means of the same computer小题2: If an examinee is not satisfied with his performance ______.

A．he can admit defeat and give it up

C．he can ask another chance within a few days

D．he is allowed to do it once again小题3:Under a computerized system, all of the following would be possible except that ______.

A．different exams can be taken in the same room

B．one doesn’t need to rush to the registration officer for taking an exam

C．it will be much easier to pass an examination

D．one can take an exam almost at any time of the year小题4:The word denied in the last sentence most probably means ______.

A．refused

B．allowed

C．lost

D．passed
