你发音上，“只，吃，师”，这三个字有点问题，你要多多联系zh ,ch ,sh ,的发音。你可以将它们和z,c,s 这三个作比较， 这有个视频http://v.youku.com/v_show/id_XMzIzNjIzMTMy.html， 55seconds,you can have a try

#2 perfect I think you have a keen ear for learning Mandarin have successfully and incidentally pronounced most characters correctly. However, it seems that your teacher haven't taught you some vowels properly. '学' xue, the u here doesn't equal to the u in su (速度), and the i in 吃只师 doesn't equal to that in li （力量）. You have pronounced all these vowels correctly when you ignored the Pinyin and just copied the sounds you heard from native speech. I think the Pinyin system should be blame for the mistakes. Another issue is that you don't pronounce j and zh, q and ch differently enough. Try listening harder. Sometimes, you pronounce them perfectly.

“学习”的“学”有点拗口，不过基本没问题。 “谢谢”很标准。 “吃”发音不准，舌头再卷一点试试看，顶住上颚。 “七”是对的。 “只”发音不准，同“吃”一样的问题，舌头再卷一点，顶住上颚试试看。 “鸡”貌似没有问题。 “希”也没什么问题。 “师”没发好，有点像“希”了，还是建议你舌头再卷一点，顶住上颚，不要在意“i”的音，努力把“sh”发清楚就好了。 “老师希望吃七个鸡蛋”， “师”“吃”没发好，使得整句话不太流畅，改进后多多练习应该会好的。 你的方法很好，继续加油哦！

嗯，你的风格有些奇怪是"吃"不是“七”两个字中“吃”的拼音是“chi"
