Based on the given IPA notations, I'll analyze each question and identify the word that differs in pronunciation from the other three.
Question 1: A. divide B. silent C. edit D. mineral
Analysis: The words "silent", "edit", and "mineral" all have the stress on the first syllable (ˈsaɪlənt, ˈɛdət, ˈmɪnərəl). On the other hand, "divide" has the stress on the second syllable (dɪˈvaɪd). Although the difference in stress is a difference in pronunciation, in this case, the difference in pronunciation that is being referred to seems to be related to the sounds of the words, rather than stress alone.
However, in this case, the words "silent", "edit", and "mineral" all end with a sound that is formed by adding a suffix (-ent, -it, and -al, respectively, to a root word), so they share similar sounds at the end of the word, whereas "divide" ends with a "de" sound. Therefore, the answer is A.
Question 2: A. knight B. knowledge C. knee D. kayak
Analysis: The words "knight", "knowledge", and "knee" all start with the "k" sound (naɪt, ˈnɑlɪʤ, ni), whereas "kayak" starts with the "k" sound but is followed by an "a" sound, making its pronunciation distinct from the other three in terms of the vowel sound following the "k" sound is not a good distinction.
However, the words "knight", "knowledge" and "kayak" all have a distinct /aɪ/ sound, whereas "knee" has a distinct /iː/ sound (ni). Therefore, the answer is C.
Question 3: A. proofs B. books C. points D. days
Analysis: The words "proofs", "books", and "points" all end with the "s" sound (prufs, bʊks, pɔɪnts), whereas "days" ends with a "z" sound (deɪz). Therefore, the answer is D.
Analyze:
'downtown' stressed at first syllable
'towel' stressed at first syllable
They have the same stress position.
Analyze:
'mechanic' stressed at second syllable
'strategic' stressed at second syllable
'fantastic' stressed at second syllable
'academic' stressed at third syllable
Therefore, 'academic' has a different stress position to other words.
