Lesson 88 Trapped in a mine
Six men have been trapped in a mine for seventeen hours. If they are not brought to the surface soon they may lose their lives. However, rescue operations are proving difficult. If explosives are used, vibrations will cause the roof of the mine to collapse. Rescue workers are therefore drilling a hole on the north side of the mine. They intend to bring the men up in a special capsule. If there had not been a hard layer of rock beneath the soil, they would have completed the job in a few hours. As it is, they have been drilling for sixteen hours and they still have a long way to go. Meanwhile, a microphone, which was lowered into the mine two hours ago, has enabled the men to keep in touch with the closest relatives. Though they are running out of food and drink, the men are cheerful and confident that they will soon get out. They have been told that rescue operations are progressing smoothly. If they knew how difficult it was to drill through the hard rock, they would lose heart.

1. Six men have been trapped in a mine for seventeen hours.
A trap is something you can’t get out of. If a critter is nibbling at your cherry tomato plants, set a trap to catch the thief. (But if it turns out to be your little brother, set him free!)
If a TV character yells, "Look out! It's a trap!" they're dramatically warning someone about an imminent surprise attack or mean-spirited trick. Other kinds of traps include a plumbing trap, a curved pipe that traps liquid in it so that gases can't rise up into your sink, and a sand trap, the tricky hollow where your ball gets stuck on a golf course. The Germanic root word of trap literally means "that onto which one steps."
如果你去旅游时，被导游带到一个你必须消费否则就不准离开的地方，那么英语对应的用法就是tourist trap，敲游客竹杠的地方.
而如果你在开车，导航则会提醒你前面有监控测速，可以用speed trap；
而用来捕捉老鼠的捕鼠器，就是mousetrap;
如果你陷入困境，难以逃脱某种牢笼，也可以用trap，表示：an unpleasant situation from which it's hard to escape
比如，失业的困境unemployment trap; 婚姻围城marriage trap; 债务枷锁debt trap; 贫困处境poverty trap; 死亡陷阱death trap
OW as in Now
to start this sound, drop the jaw, the first sound is similar to the sound [æ] as in bat[bæt]
the tongue is wide and flat, the back stretched up a little bit, the tongue tip touches the back of the bottom front teeth.
the upper lip might lift a little or it would be relaxed
to transition into the second position, the lips round and the jaw drops less,
the back of the tongue stretches up more
this second position is considered to same as the [ʊ] as in push[pʊʃ] vowel.
but when it's a part of diphthong, the lips round more than when it occurs as a pure vowel.

练习感悟：
1. 双元音发的不够到位、饱满
2. operation[ˌɑpəˈreɪʃən]中的o很想要发成ˌɒpəˈreɪʃən，因为对于【ɒ】跟【ɑ】很容易嘴型没有到位就会混淆，看到LISA美语说，其实对于很多美国人来说，这二者没有区别会稍稍安心，但是，看到Rachel跟其他语音书对二者的描述，又强迫症发作，非得念出个不同来，结果就是所有有关于二者的音我听着都觉着我念的差不多，不过如果念的是【ɒ】，我的面部会紧张，根据这一点，我确信我念的都是【ɑ】的音，这个音面部跟嘴唇都很放松，jaw drops就行了。但是，如果有【ɒ】的音，我也会倾向于念成【ɑ】，比如本文的cause, brought,面部不够紧张，所以听着也像是【ɑ】的音。
3.今天声音基本上恢复正常，有一个好身体，才能好好学习。就像娃儿爸说的，没事儿起来动一动，暖和一下~~
