I. Choose the word whose underlined part is pronounced differently from the others. 1. a. staircase /ˈstɛrkeɪs/ b. decorate /ˈdɛkəreɪt/ c. communal /kəmˈjunəl/ d. receive /rɪˈsiv/ The underlined part is the prefix of the word. Analyzing the pronunciation, we see that 'com-' in 'communal' is /kəm/ while 'de-' in 'decorate' is /ˈdɛ/, 're-' in 'receive' is /rɪ/, and 'sta-' in 'staircase' is /ˈstɛr/. So the correct answer is b, c or d. 2. a. festival /fɛsˈtɪvəl/ is not provided, however, we can infer festival's 'fest-' is /fɛs/. b. minority /məˈnɔrəti/ c. tribal /ˈtraɪbəl/ d. title /ˈtaɪtəl/ The underlined part is the prefix or the beginning of the word. Analyzing the pronunciation, we see that 'mi-' in 'minority' is /mə/, 'tri-' in 'tribal' is /ˈtraɪ/, and 'ti-' in 'title' is /ˈtaɪ/. So the correct answer is b. 3. a. offerings /ˈɔfərɪŋz/ b. along /əˈlɔŋ/ c. longevity /lɔnˈʤɛvəti/ d. singer /ˈsɪŋər/ The underlined part is the suffix or the middle of the word. Analyzing the pronunciation, we see that '-ing' in 'offerings' is /ɪŋz/, '-ong' in 'along' is /ɔŋ/, and '-ong' in 'longevity' is /ɔn/, and '-er' in 'singer' is /ər/. So the correct answer is c. 4. a. detached /dɪˈtæʧt/ b. offered /ˈɔfərd/ c. joined /ʤɔɪnd/ d. called /kɔld/ The underlined part is the suffix or the end of the word. Analyzing the pronunciation, we see that '-ed' in 'detached' is /ˈtæʧt/ (different from typical '-ed' in English), '-ed' in 'offered' is /ərd/, '-ed' in 'joined' is /ʤɔɪnd/ (typically, '-ed' is pronounced /d/ or /t/, but 'joined' is /ʤɔɪnd/, not a typical '-ed' sound) and 'called' is /kɔld/. So the correct answer is a or c. 5. a. garden /ˈgɑrdən/ b. villager /ˈvɪlɪʤər/ c. gong /gɔŋ/ d. pagoda /pəˈgoʊdə/ The underlined part is the vowel sound 'o'. Analyzing the pronunciation, we see that 'o' in 'gong' is /ɔŋ/, 'o' in 'villager' and 'garden' are /ɔ/ in 'vɪlɪʤər' and 'gɑr' respectively, and 'o' in 'pagoda' are /oʊ/. So the correct answer is c
