The Turing machine is an abstract（71)of computer execution and storage introduced in 1936

The Turing machine is an abstract(71)of computer execution and storage introduced in 1936 by Alan Turing to give a mathematically precise definition of(72). or 'mechanical procedure'. As such it is still widely used in theoretical computer science, especially in(73)theory and the theory of computation. The thesis that states that Turing machines indeed capture the informal notion of effective or mechanical method in logic and mathematics is known as Turing's thesis.

Every Turing machine computes a certain(74)partial function over the strings over its alphabet. In that sense it behaves like a computer with a fixed program. However, as Alan luring already described, we can encode the action table of every Turing machine in a string. Thus we might try to construct a Turing machine that expects on its tape a string describing an action table followed by a string describing the input tape, and then computes the tape that the encoded Turing machine would have computed. As Turing showed, such a luring machine is indeed possible and since it is able to simulate any other Turing machine it is called a(75)Turing machine.

A universal Turing machine is Turing complete. It can calculate any recursive function, decide any recursive language, and accept any recursively enumerable language. According to the Church-Turing thesis, the problems solvable by a universal Turing machine are exactly those problems solvable by an algorithm or an effective method of computation, for any reasonable definition of those terms.

A．implement

B．pattern

C．tool

D．model

听力原文： Bows and arrows are one of man's oldest weapons. They gave early man an effective weapon to kill his enemies. The ordinary bow or shoat bow was used by nearly all early people. This how had limited power and short range. However, man overcame these faults by learning to track his targets at a close range. The long how was most likely discovered when someone found out that a fivefoot piece of wood made a better bow than a threefood piece. Hundreds of thousands of these bows were made and used for three hundred years. However, not one is known to survive today. We believe that a force of about one hundred pounds was needed to pull the string all the way back on a long bow. For a long time the how was just a bent stick and string. In fact, more changes have taken place in a bow in the past 25 years than in the last 7 centuries. Today, bow is forceful. It is as exact as a gun. In addition, it requires little strength to draw the string. Modem bows also have precise aiming devices. In indoor contest, perfect scores from 40 yards are common. The invention of the bows itself ranks with discovery of fire and the wheel. It was a greatstepforward for ream.

(23)

A．Because it was too heavy.

B．Because it did not bend easily.

C．Because it did not shoot far.

D．Because its string was short.

第3题

A hearing test that analyses brain waves for subconscious responses to sound has recently

been devised by a team of specialists at the University of Iowa. Instead of depending on the patient to indicate when he hears a laboratory-controlled noise, as in the traditional form. of testing, this new method, called electric response audiometry, enables audiologists to trace the noise's path directly from the ear to the brain while the patient relaxes or sleeps. Although brain responses have been used in other auditory tests for some time, the University of Iowa specialists are the only scientists to date who analyze simultaneously three components of hearing—the responses of the middle ear, the auditory nerve, and the brain stem. This information helps to identify the precise location of a hearing problem and, at the same time, to measure its severity. While electric response audiometry is not meant to replace conventional means of testing, it is specially effective in diagnosing hearing problems in very young children, multiply handicapped individuals, and psychologically disturbed persons because it does not require the patient's active participation.

According to the passage, electric response audiometry can be used ______.

A．whether a person is awake or asleep

B．only if a person is relaxed

C．particularly if a person hears a loud noise

D．particularly when a person is dreaming

Section B

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.

听力原文： A poorly trained manager can make an employee's life miserable. In 99 out of 100 cases, (30)the reason employees feel demoralized and no longer like their. jobs is because they have a new boss who doesn't appreciate them, doesn't listen to them, or generally erodes their self-esteem. (31)Three basic skills that every manager should use in order to be effective on the job are: being specific, enhancing others' self-esteem and listening effectively. Being specific means giving work instructions that are precise, and being clear about what is to be done and the results to be achieved. Being specific means describing the behaviors of people rather than labeling people. It includes giving both positive feedback that tells them what to repeat and corrective feedback that is firm, yet non-critical. Then it comes to building the employees up. Self-esteem is a private, individual matter. It is not fixed, but goes up and down from day to day, or even from hour to hour. Thus, enhancing self-esteem is no easy task Managers can't "make" people feel good about themselves. Rather, self-esteem is like a door that's locked from the inside. A final skill that today's managers need more than ever is listening. Listening may seem like a commonplace skill, but it is not practiced nearly as much as it needs to be in business today. (32)People tend to think about what they are going to say in rebuttal when another person is talking, instead of focusing on what that person is saying and what he or she means.

(27)

A．They are not appreciated.

B．The boss does not listen to their advice.

C．Self-esteem is hurt.

D．They are poorly paid.

第10题

A survey is a study, generally in the form. of an interview or a questionnaire, that provi

des

information concerning how people think and act. In the United States, the best-known

surveys are the Gallup poll and the Harris poll. As anyone who watches the news during Line

campaigns presidential knows, these polls have become an important part of political life in

(5) the United States.

North Americans are familiar with the many "person on the street？ interviews on local

television news shows. While such interviews can be highly entertaining, they are not

necessarily an accurate indication of public opinion. First, they reflect the opinions of only

those people who appear at a certain location. Thus, such samples can be biased in favor

(10)of commuters, middle-class shoppers, or factory workers, depending On which area the

newspeople select. Second, television interviews tend to attract outgoing people who are

willing to appear on the air, while they frighten away others who may feel intimidated by

a camera. A survey must be based on a precise, representative sampling if it is to genuinely

reflect a broad range of the population.

(15) In preparing to conduct a survey, sociologists must exercise great care in the wording

of questions. An effective survey question must be simple and clear enough for people to

understand it. It must also be specific enough so that there are no problems in interpreting

the results. Even questions that are less structured must be carefully phrased in order to elicit

the type of information desired. Surveys can be indispensable sources of information, but

(20)only if the sampling is done properly and the questions are worded accurately.

There are two main forms of surveys: the interview and the questionnaire. Each of these

forms of survey research has its advantages. An interviewer can obtain a high response rate

because people find it more difficult to turn down a personal request for an interview than

to throw away a written questionnaire. In addition, an interviewer can go beyond written

(25)questions and probe for a subject's underlying feelings and reasons. However, questionnaires

have the advantage of being cheaper and more consistent.

What does the passage mainly discuss？

A．The history of surveys in North America

B．The principles of conducting surveys

C．Problems associated with interpreting surveys

D．The importance of polls in American political life
