答案

解析
① A. sister /ˈsɪstər/，重音在第一个音节；B. teacher /ˈtiːtʃər/，重音在第一个音节；C. today /təˈdeɪ/，重音在第二个音节。
② A. elephant /ˈelɪfənt/，重音在第一个音节；B. interesting /ˈɪntrəstɪŋ/，重音在第一个音节；C. machine /məˈʃiːn/，重音在第二个音节。
③ A. doctor /ˈdɒktər/，重音在第一个音节；B. teacher /ˈtiːtʃər/，重音在第一个音节；C. guitar /ɡɪˈtɑː/，重音在第二个音节。
④ A. exciting /ɪkˈsaɪtɪŋ/，重音在第二个音节；B. Tuesday /ˈtjuːzdeɪ/，重音在第一个音节；C. father /ˈfɑːðər/，重音在第一个音节。
⑤ A. tomorrow /təˈmɒrəʊ/，重音在第二个音节；B. beautiful /ˈbjuːtɪfl/，重音在第一个音节；C. interesting /ˈɪntrəstɪŋ/，重音在第一个音节。
⑥ A. about /əˈbaʊt/，重音在第二个音节；B. father /ˈfɑːðər/，重音在第一个音节；C. before /bɪˈfɔːr/，重音在第二个音节中（此题考察的是双音节词重读，before重读在第二个音节，father在第一个音节，所以选C的情况不符合（题目要求找两个重读位置相同，而与其他不同的词），实际这里B是第一个音节重读，A和C是第二个音节，所以选B。） （根据题目实际要求，这里找的是重音位置不同的选项，因此第⑥题中B与其他两个不同）
