曾经苏得太惨，现在回到正常了，很感谢（崔义信，8-8-9-7-3-2-5-8），其实搞这个需要很多，比如统计学，概率学，分析，归纳等，如果你不具备这些，不要自己去搞，我以前就是胡乱相信自己，结果越陷越深。还好这辈子运气好，遇到他，把我拉上来了，想想以前天天灰心绝望，迷茫无助，太痛苦了。如果情况和我相同，可以蔚他。
I h***e 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 ***all 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.
