根据材料请回答Pronouncing a language is a skill.Every normal person is expert in the skill of pro-nouncing his own language; but few people are even moderately proficient 51 pronounc-ing foreign languages.Now there are many 52 for this, some obvious, some perhaps not so obvious.But I suggest that the fundamental reason why people in general do not speak foreign languages very much better than they do is that they fail to grasp the true nature of the problem of learning to pronounce, and consequently never set about tackling it in the right 53 .Far too many people fail to realize that 54 a foreign language is a skill one that needs careful training of a special kind, and one that cannot be acquired by just 55 it to take care of itself.I think even teachers of language, while recognizing the impor-tance of a good accent, tend to neglect, in their practical teaching, the branch of study concerned 56 speaking the language.So the first point I want to make is that English.Pronunciation must 57 ; the teacher should be prepared to devote some of the lesson time 58 this, and by his whole attitude to the subject should get the student to feel that here is a matter 59 of receiving his close attention.So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take sec-ond 60 .61 from this question of the time give to pronunciation, there are two other require-ments for the teacher: the first, knowledge; the second, technique.
It is important that the teacher should be in 62 of the necessary information.This can generally be obtained from books.It is possible to get from books some idea of the me- chanics of speech, and of what we call general phonetic theory.It is also possible in this way to get a clear mental picture of the 63 between the sounds of different languages, be- tween the speech habits of English people and those, say, of your students.Unless the teacher has such a picture, any comments he may make on his students' pronunciation are unlikely to be of 64 use, and lesson time spent65 pronunciation may welt be time was-ted. A．with
