问答题There are great impediments to the general use of a standard in pronunciationcomparable to that existing in spelling (orthography). One is thefact that pronunciation is learnt ‘naturally’ and unconsciously, and orthography 1._______is learnt deliberately and consciously. Large numbers of us, in fact, remainthroughout our lives quite unconscious with what our speech sounds         2._______like when we speak out, and it often comes as a shock when we            3._______firstly hear a recording of ourselves. It is not a voice we recognize at once,   4._______whereas our own handwriting is something which we almost always know. We      5._______begin the ‘natural’ learning of pronunciation long before we start learning toread or write, and in our early years we went on unconsciously imitating and    6._______practicing the pronunciation of those around us for many more hours per every    7._______day than we ever have to spend learning even our difficult English spelling.This is ‘natural’, therefore, that our speech-sounds should be those of our im  8._______mediate circle; after all, as we have seen, speech operates as a means of holding acommunity and to give a sense of ‘belonging’. We learn quite early to recognize a 9._______‘stranger’, someone who speaks with an accent of a different community — perhapsonly a few miles far.                               10._______

问答题For a clearer picture of what the student knows, most of teachers use another   1._______kind of examination in addition to objective tests. They use “essay” tests, whichrequire students to write long answers of broad, general questions. One advantage  2._______of the essay test is that it reduces the element of lucky. The students cannot    3._______get high score just by making a lucky guess. Other advantage is that it shows the  4._______examiner more about the student’s ability to put facts together into a meaningfulwhole. It should show what deeply he has thought of the subject. Sometimes,      5._______though, essay tests have disadvantages, either. Some students are able to write   6._______good answers without really knowing much about the subject, as other students     7._______who actually know the material have trouble to express their ideas in essay     8._______form.  Besides, on an essay test the student’s score may depend on theexaminer’s feelings at the time of reading the answer. If he is feeling tired orbored, the student may receive a lower score than he should. Another examinerreading the same answer might give it much high mark. From this standpoint      9._______the objective test gives each student a fairer chance.  Whether an objective test or an essay test are used, problems arise. When    10._______some objective questions are used along with some essay questions, however, afairly clear picture of the student’s knowledge can usually be obtained.
