They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions.

知识笔记：
单词：1、performance: 表演; 演出;表现; 性能; 业绩; 工作情况;2、occasion：场合，时机，机会；
音标：/eɪ/：they，train，station，stay，day，always，same，occasion；
/eɪ/是元音音标，属于开合（也叫合口）双元音。学习这个音之前先学习/e/和/ɪ/的发音。发音时先发/e/然后滑向/ɪ/音，/ɪ/发得轻而短几乎只做口型。
练习感悟：纠正了singer，singing这两个单词的读法，以前老师教的是g，原来不是的，应该发鼻音。还复习了2个单词，这篇课文感觉内容比较容易。
