Lesson 4 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.

知识笔记：
1:谢谢@Jack_北京_健身，昨天给我指出th发音ð，不到位，所以今天特地练习了ˈð，
there/the/brother等
2:
学习感悟：
1:过于毛燥，在语音语调上需要下大力气模仿。/发音不够圆润，醇厚，所以听起来轻飘飘的。
