练习材料：Lesson 88 Trapped in a mine 时长: 85s
Six men have been trapped in a mine for seventeen hours.
sɪks mɛn hæv biːn træpt ɪn ə maɪn fɔː ˈsɛvnˈtiːn ˈaʊəz.
If they are not brought to the surface soon they may lose their lives.
ɪf ðeɪ ɑː nɒt brɔːt tuː ðə ˈsɜːfɪs suːn ðeɪ meɪ luːz ðeə lɪvz.
However, rescue operations are proving difficult.
haʊˈɛvə, ˈrɛskjuː ˌɒpəˈreɪʃənz ɑː ˈpruːvɪŋ ˈdɪfɪkəlt.
If explosives are used, vibrations will cause the roof of the mine to collapse.
ɪf ɪksˈpləʊsɪvz ɑː juːzd, vaɪˈbreɪʃənz wɪl kɔːz ðə ruːf ɒv ðə maɪn tuː kəˈlæps.
Rescue workers are therefore drilling a hole on the north side of the mine.
ˈrɛskjuː ˈwɜːkəz ɑː ˈðeəfɔː ˈdrɪlɪŋ ə həʊl ɒn ðə nɔːθ saɪd ɒv ðə maɪn.
They intend to bring the men up in a special capsule.
ðeɪ ɪnˈtɛnd tuː brɪŋ ðə mɛn ʌp ɪn ə ˈspɛʃəl ˈkæpsjuːl.
If there had not been a hard layer of rock beneath the soil, they would have completed the job in a few hours.
ɪf ðeə hæd nɒt biːn ə hɑːd ˈleɪər ɒv rɒk bɪˈniːθ ðə sɔɪl, ðeɪ wʊd hæv kəmˈpliːtɪd ðə ʤɒb ɪn ə fjuː ˈaʊəz.
As it is, they have been drilling for sixteen hours and they still have a long way to go.
æz ɪt ɪz, ðeɪ hæv biːn ˈdrɪlɪŋ fɔː ˈsɪksˈtiːn ˈaʊəz ænd ðeɪ stɪl hæv ə lɒŋ weɪ tuː gəʊ.
Meanwhile, a microphone, which was lowered into the mine two hours ago, has enabled the men to keep in touch with the closest relatives.
ˈmiːnˈwaɪl, ə ˈmaɪkrəfəʊn, wɪʧ wɒz ˈləʊəd ˈɪntuː ðə maɪn tuː ˈaʊəz əˈgəʊ, hæz ɪˈneɪbld ðə mɛn tuː kiːp ɪn tʌʧ wɪð ðə ˈkləʊsɪst ˈrɛlətɪvz.
Though they are running out of food and drink, the men are cheerful and confident that they will soon get out.
ðəʊ ðeɪ ɑː ˈrʌnɪŋ aʊt ɒv fuːd ænd drɪŋk, ðə mɛn ɑː ˈʧɪəfʊl ænd ˈkɒnfɪdənt ðæt ðeɪ wɪl suːn gɛt aʊt.
They have been told that rescue operations are progressing smoothly.
ðeɪ hæv biːn təʊld ðæt ˈrɛskjuː ˌɒpəˈreɪʃənz ɑː prəʊˈgrɛsɪŋ ˈsmuːðli.
If they knew how difficult it was to drill through the hard rock, they would lose heart.
ɪf ðeɪ njuː haʊ ˈdɪfɪkəlt ɪt wɒz tuː drɪl θruː ðə hɑːd rɒk, ðeɪ wʊd luːz hɑːt.
