Lesson27 A wet night
Late in the afternoon, the boys put up their tent in the middle of a field. As soon as this was done, they cooked a meal over an open fire. They were all hungry and the food smelt good. After a wonderful meal, they told stories and sang songs by the camp fire. But some time later it began to rain. The boys felt tired so they put out the fire and crept into their tent. Their sleeping-bags were warm and comfortable, so they all slept soundly. In the middle of the night, two boys woke up and began shouting. The tent was full of water! They all leapt out of their sleeping-bags and hurried outside. It was raining heavily and they found that a stream had formed in the field. The stream wound its way across the field and then flowed right under their tent!

任务配置：L0+L1+L4
知识笔记：
1.朗读(L0): 提交录音的时长为1分16秒，原音正文部分1分18秒左右。
2. 音标(L1):hungry /ˈhʌŋgri/ hurried /ˈhʌrɪd/ heavily /ˈhɛvɪli/ had /həd/
h/h/
1）张开嘴巴，让气流自由逸出口腔，不受阻碍。
2）只在通过声门时形成轻微的摩擦，舌头和嘴唇的位置随其后的元音而变化。
3）发音时，声带不震动。
4）/h/是个清辅音，声音不震动，送气很大，可以拿一张白纸放在嘴前，感受一下气流。不要发成汉语中的"喝"。
3. 今天是第二十七天: 自己以前发音另一个问题是总是不自觉地将很多元音发音位置都是靠前和靠上，相当于这些音是挤在一起的。实际上发音时要时刻将下巴放松的同时要靠后和靠下，而且下唇要向两边拉，以避免发音时挤在一起形成阻碍。这样发后元音时不需要变化，而发央元音和前元音时，只要将舌位摆好即可。
