美式英语正音训练第66期:练习4(11)

 　　Exercise 4-11 :

　　Voiced and Unvoiced Sounds with T

　　This exercise is for the practice of the difference between words that end in either a vowel¹ or a voiced consonant²,

　　which means that the vowel is lengthened³ or doubled.

　　Therefore, these words are on a much larger, longer stairstep.

　　Words that end in an unvoiced consonant are on a smaller, shorter stairstep.

　　This occurs whether the vowel in question is tense or lax.

　　ha! hod hot

　　har hard heart

　　hall hailed halt

　　her heard hurt

　　hole hold holt

　　hoe hoed

　　caw cod cot/caught

　　car card cart

　　call called

　　cur curd curt

　　coal cold colt

　　co- code coat

1 vowel

参考例句：

• A long vowel is a long sound as in the word"shoe ".长元音即如“shoe” 一词中的长音。
• The vowel in words like 'my' and 'thigh' is not very difficult.单词my和thigh中的元音并不难发。

2 consonant   

n.辅音；adj.[音]符合的

参考例句：

• The quality of this suit isn't quite consonant with its price.这套衣服的质量和价钱不相称。
• These are common consonant clusters at the beginning of words.这些单词的开头有相同辅音组合。

3 lengthened
