Lesson 90 What's for supper?
Fish and chips has always been a favourite dish in Britain, but as the oceans have been overfished, fish has become more and more expensive. So it comes as a surprise to learn that giant fish are terrifying the divers on North Sea oil rigs. Oil rigs have to be repaired frequently and divers, who often have to work in darkness a hundred feet under water, have been frightened out of their wits by giant fish bumping into them as they work. Now they have had special cages made to protect them from these monsters. The fish are not sharks or killer whales, but favourite eating varieties like cod and skate which grow to unnatural sizes, sometimes as much as twelve feet in length. Three factors have caused these fish to grow so large: the warm water round the hot oil pipes under the sea; the plentiful supply of food thrown overboard by the crews on the rigs; the total absence of fishing boats around the oil rigs. As a result, the fish just eat and eat and grow and grow in the lovely warm water. Who eats who?

知识笔记：
/ɔɪ/
1）学习该音发音方法请先学习/ɔː/和/ɪ/这两个单元音。
2）发音时下颌张开，嘴唇略呈圆形，稍稍向外突出。
3）舌前部收缩，舌后部向软颚抬起，但不要接触到软颚。
4）舌身放松前探，舌尖轻触下齿，舌前部微微抬起。整个过程就是从/ɔː/音慢慢滑向/ɪ/。
注意：/ɔɪ/是个"开合双元音"，即牙床由半开到接近半合，口形由稍大而圆变为小而扁。发音时舌位由低到高，由舌后部抬高滑向舌前部抬高，音量由强到弱，由长到短，由清晰到含糊。

练习感悟：
1.前三遍听材料，很多小细节没听懂，看了原文后还翻译错了。把diver当成了捕鱼的（……），后面就完全理解错了。所以听力时不要在材料结束前强行加戏，比如一开始我没懂巨大的鱼为什么威胁到潜水员，就把diver当做潜水捕鱼的人，其实后面解释了是石油钻塔的工作人员在检修设备时需要潜水，深海非常黑暗被鱼撞到了，才害怕的。
2.今天的材料仔细听了，录老师音节之间的转换很漂亮啊好好听，我的话还是会卡壳，还是不顺滑， 原因一个是舌头的肌肉力量不够，也就是没习惯说英文，朗读时看着材料还会读错呢，第二个是，单词读错了，没有仔细的看音标。为什么要有音标，就像汉语有拼音一样， 音标就是英语的拼音啊。
3.没听懂的时候，很沮丧，觉得自己还是单词量不够，其实朗读只是一个切入点，如果要把材料研究透或者把朗读模仿的很像，是需要通过学习很多其他的知识才能达到的，比如英语的语音语调，群文件里有这本。不过呢，不着急，因为我还处于懒惰的阶段，不给自己压力，让自己慢慢的体会学习的快乐，万事开头难，打好基础，少就是多，快就是慢。材料简单也能学到很多，只要我想。
4.啊，加油啦，周末时间很多，可还是……很懒呀。哈哈哈哈。
