The Last Two Rules
最后两条规则
Why 鱼 is written yú, and why a third tone almost never finishes. Both are short — you will probably get them on the first read.

Rule one: a syllable can't start with i, u or ü on paper
Same sound, different spelling
Every one of these is a word you already know. Listen for the fact that nothing changed.

Rule two: a third tone almost never finishes
You have been taught the third tone as a dip that comes back up. That full shape happens in only two places: when the word stands alone, and at the end of a phrase. Everywhere else — before a first, second or fourth tone, or before a light syllable — it only does the first half. It sinks low and stays there. It never rises. 老师 lǎoshī, 美国 Měiguó, 可乐 kělè: every one of those third tones is a low sink, not a dip-and-rise. Performing the full shape every time is the single loudest thing that makes a learner sound like a textbook rather than a person.
你学到的三声是「先降后升」。那个完整的形状只在两个地方出现:这个字单独念的时候,和它在句尾的时候。其它所有位置——后面跟着一声、二声、四声,或者跟着一个轻声——它只做前半段:沉下去,停在低处,不升上来。老师 lǎoshī、美国 Měiguó、可乐 kělè,这里面每一个三声都只是低低地沉住,不是降升。每次都把完整形状演一遍,是让一个学习者听起来像课本而不像真人的最大原因。
Low and staying there — listen for what does NOT happen
Four words you know. In each one the third tone sinks and stops. Nothing rises.

Before you go课后回顾
- Write out the pinyin for 一, 五, 鱼, 我, 有, 月 from memory. If a y or a w is missing, that is the rule you just learned.
- Say 老师 and 好 back to back. The first 老 sinks and stops; the lone 好 dips and rises. Feel the difference — that is the whole of rule two.
- Anything from the last nine lessons still shaky? Say so before the test — that is what the test is for, not to catch you out.
