Lesson4 An exciting trip
I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.

练习感悟：
He发i：，老是读成e，反复练习去改，不练习不听自己的声音，一直不知道自己的发音是错的。读重音和断句还需要不断练习，最后一个音是降调，读成了升调。
