第5题：

Which of the following is true of English sound system


A.Aspiration is a distinctive feature.

B.Voicing is a distinctive phonetic feature.

C.Nasalization of vowels gives rise to another vowel.

D.Length of vowels differentiates one vowel from the other.

答案：B
解析：
考查发音系统的区别特征。雅格布逊在20世纪40年代首先提出区别特征(distinctivefeature)这一想法，目的是找出一套音系的对照或对比特征．以概括语音的某些方面，比较重要的区别特征有：[辅音][响音][鼻音][带声]等。[辅音]特征可以区分辅音和元音，即所有辅音都是[+辅音]，所有元音都是[-辅音]。 [响音]特征用来区分所谓阻塞音(塞音、擦音及塞擦音)和响音(其他辅音和元音)，即阻塞音是[-响音]，响音是[+响音]。[鼻音]和[带声]自然就是用来分别区分鼻音(包括鼻化音)和带声音的特征。这些特征都是二分特征，可以区分出两种情况：有该特征的和没有该特征的。元音的长短只能区分单元音，并不能区分双元音，D项说法不正确。故选B。

解析：
考查英语教师需具备的特征。题目问“下面哪一项不能被看作是一个成功的英语老师所具备的特征”。A项“考虑学习者的需求”，B项“具备良好的英语技能”，C项“促进交际活动”，D项“只按照课本走”。很显然，D项是错误的表述，故选D。

Which of the following is the feature shared by the English phonemes/m/and/p/


A.Voiced.

考查英语音素。根据英语辅音的分类可知，按照声带振动与否，／m／是浊辅音，／p／是清辅音；按照发音部位，二者都是双唇音；按照发音方式，／m／是鼻音，／p／是塞音。／m／和／p／共同的特征是双唇音，故选C。
