练习材料：新概念第二册 Lesson 9 A cold welcome
On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing.

知识笔记：
1、上次学习/v/是时候觉得自己不可能读错，今天第一遍录音时，发现很多都城了/f/,尤其twelve的发音老是出错。
2、/eɪ/的发音。
学习该音发音方法请先学习/e/和/ɪ/这两个单元音。
嘴巴张开成半圆形，开始发/e/音。
然后颚部慢慢抬起滑向/ɪ/音，嘴唇慢慢合上。
注意：/eɪ/是个"合口双元音"，即牙床由半开到接近半合，由大到小。发音时音量从强到弱，前长后短，前重后轻。
练习感悟：
1、把语速放慢读发现自己有好多不确定的发音问题，自己读的时候往往就一概而过，很多音错了很多年都不自知。
2、觉得自己的发音真的好难听，流畅度也很弱，归根到底还是练习太少。
