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.

任务配置：L0+L1+L4
知识笔记：
1.朗读(L0): 提交录音的时长为47秒，原音正文部分47秒左右。
2. 音标(L1):firm /fɜːm/different /ˈdɪfrənt/From/frəm/ fly/flaɪ/ before/bɪˈfɔː/ finding/ˈfaɪndɪŋ/
唇齿摩擦辅音。
发音时下唇轻触上齿，气流由唇齿间通过，形成摩擦音。
是清辅音，声带振动。
3. 今天是第四天: 语调的掌握还是没有找到感觉，知道重要的词要读的时间长点，音高要高一些。只是在句子里读的时候，就没有感觉了。
