Lesson 21 Mad or not
Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built years ago, but for some reason it could not be used then. Last year, however, it came into use. Over a hundred people must have been driven away from their homes by the noise. I am one of the few people left. Sometimes I think this house will be knocked down by a passing plane. I have been offered a large sum of money to go away, but I am determined to stay here. Everybody says I must be mad and they are probably right.

感悟：堅持21天的小小收獲
1:一開始不明白為什么要控制時間，原來每個單詞要讀正確，發音完整需要的時間是有要求的。一個句子中有可能為了一個爆破音會出現一段憋氣。所以整體時間控制了，就不會有太大差異。
2:為什么自己讀的語音平淡沒有起伏。
（1）誤以為一個句子起伏是感情語調自己控制。會在句子后面或者開頭起伏。事實上是每個單詞決定的。比如中文的疊詞一樣，只有把每個單詞讀好了，才能整個句子有起伏。
（2）句子的停頓，目前還是根據意群或者語法結構來停頓，聽多了發現不是的，是根據句子連讀來停頓。
以上是這21天練習中的一點感悟，在接下來練習中會落實到每個單詞，每個短句中。
