1.
Mixed
Correct Answer
A. /t/
Explanation
The correct answer is /t/. In English, the /t/ sound is produced by placing the tip of the tongue against the alveolar ridge, which is the bumpy area behind the upper front teeth. This sound is commonly found at the beginning or in the middle of words, such as "time" or "water." In this case, the sound /t/ corresponds to the given word "mixed."
2.
Smoked
Correct Answer
A. /t/
Explanation
The correct answer is /t/ because the word "smoked" ends with the sound /t/. In English, the past tense ending "-ed" can be pronounced in three different ways: /t/, /d/, or /id/. The pronunciation of "-ed" depends on the last sound of the base verb. In this case, the base verb is "smoke" and it ends with the sound /k/, which is not a voiced sound. When the base verb ends with an unvoiced sound, like /k/, /p/, or /s/, the "-ed" ending is pronounced as /t/.
3.
Coughed
Correct Answer
A. /t/
Explanation
The correct answer is /t/. In the word "coughed," the final sound is a voiceless alveolar stop, which is represented by the /t/ sound. This can be heard when pronouncing the word, as the final sound is a quick and abrupt stop of airflow.
4.
Clapped
Correct Answer
A. /t/
Explanation
The correct answer is /t/. In the word "clapped," the final sound is a voiceless alveolar stop, which is represented by the phoneme /t/. This sound is produced by stopping the airflow with the tongue against the alveolar ridge, then releasing it abruptly.
5.
Erased
Correct Answer
A. /t/
Explanation
The given answer is /t/. This is because when a word ends in a voiceless consonant sound (such as /p/, /k/, /s/, etc.), the regular past tense ending "-ed" is pronounced as /t/. In this case, "erased" ends in the voiceless consonant sound /s/, so the regular past tense ending is pronounced as /t/.
6.
Touched
Correct Answer
A. /t/
Explanation
The correct answer is /t/. This is because the word "touched" ends with the /t/ sound, as in the word "t".
7.
Carried
Correct Answer
B. /d/
Explanation
The word "carried" ends with the sound /d/. This is because the letter "d" is pronounced as /d/ when it comes after a vowel sound, as in the word "carried". The other options, /t/ and /id/, do not match the pronunciation of the word "carried".
8.
Offered
Correct Answer
B. /d/
Explanation
The given answer, /d/, represents the correct pronunciation of the past tense and past participle form of the verb "offer." In English, regular verbs ending in a voiced consonant sound, such as /f/, /v/, /g/, /b/, etc., are pronounced with a /d/ sound in their past tense and past participle forms. Therefore, "offered" is pronounced as /ˈɔfərd/.
9.
Happened
Correct Answer
B. /d/
Explanation
The given correct answer is /d/. In English pronunciation, the final sound of regular verbs in the past tense is often pronounced as /d/. This is the case when the verb ends in a voiced consonant sound, such as in "happened." The /d/ sound is made by vibrating the vocal cords and is softer compared to the /t/ sound. Therefore, when pronouncing the past tense of "happen," we say /hæpənd/.
10.
Preferred
Correct Answer
B. /d/
Explanation
The correct answer is /d/. In the word "preferred," the final sound is a voiced /d/ sound, not a voiceless /t/ sound or a /id/ sound. This can be determined by pronouncing the word and paying attention to the sound made at the end.
11.
Travelled
Correct Answer
B. /d/
Explanation
The correct answer is /d/. In the word "travelled," the final sound is pronounced as /d/. This is because the word ends with the letter "d," which is a voiced consonant. When a voiced consonant is followed by a vowel sound, it is pronounced as /d/.
12.
Painted
Correct Answer
C. /id/
Explanation
The given answer "/id/" is correct because the word "painted" ends with the sound /t/, which is voiceless. According to the rules of English pronunciation, when a word ends with a voiceless sound like /t/, and the next word begins with a vowel sound, the final sound of the first word changes to /id/. This is known as the "voiced ending" rule, where the /t/ sound is pronounced as /id/. Therefore, in the word "painted," the /t/ sound changes to /id/ when followed by a word starting with a vowel sound.
13.
Hated
Correct Answer
C. /id/
Explanation
The word "hated" ends with the sound /id/. In English, when a regular verb ends in a /t/ or /d/ sound, the -ed ending is pronounced as /id/. This occurs when the base form of the verb ends in a /t/ or /d/ sound as well, as is the case with "hate". Therefore, the correct pronunciation of "hated" is /id/.
14.
Folded
Correct Answer
C. /id/
Explanation
The word "folded" ends with the sound /d/, which is voiced. According to the rule of pronunciation, when a word ends with a voiced sound (except /d/ or /t/), the ending -ed is pronounced as /id/. Therefore, the correct pronunciation of "folded" is /fold-id/.
15.
Needed
Correct Answer
C. /id/
Explanation
The correct answer is /id/. In English, when the base form of a verb ends in the sounds /t/ or /d/, the regular past tense ending is pronounced as /id/. This is the case for verbs like "needed" where the base form ends in /d/. So, the correct pronunciation of the past tense of "needed" is /'niːdɪd/.
16.
Arrested
Correct Answer
C. /id/
Explanation
The correct answer is /id/. In the word "arrested," the final sound is a voiced dental stop, which is represented by the /d/ sound. This sound is followed by a /t/ sound, which is a voiceless dental stop. When two voiceless consonants occur together, the final sound is often assimilated to match the voicing of the following sound. In this case, the /d/ sound becomes a /t/ sound to match the voicelessness of the /t/ sound. Therefore, the correct pronunciation of "arrested" is /arɛstɪd/.
17.
Voted
Correct Answer
C. /id/
Explanation
The word "voted" is pronounced with the /id/ sound at the end because it ends in a voiced consonant sound (/d/). According to the rule of pronunciation, when a word ends in a voiced consonant sound, the -ed ending is pronounced as /id/. In this case, the /d/ sound is followed by the /id/ sound, resulting in the pronunciation of /id/.
