练习材料：Lesson18 He often does this!
After I had had lunch at a village pub, I looked for my bag. I had left it on a chair beside the door and now it wasn't there! As I was looking for it, the landlord came in. 'Did you have a good meal?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The landlord smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.'

知识笔记：本课继续对比美式音标长元音i和短元音 I，发长元音的词汇有eighteen, he, meal, immediately, me, very, sorry，由字母“ee” “e” “ea” “y” 发此音。发短元音的词汇有this, listen, village, it, beside, looking, did, bill, minutes, returned, with, 由字母 “i” “a” “e” “u” 发此音。本课语法是过去完成时和现在完成时，有较多的连读和轻音。
练习感悟：个别元音口腔变化较大时要读得更久一点，句号停顿时间比逗号更长。
