 如果你要是误以为所有词典里的标注或者示范都是 “权威的”、“标准的”，那么，没比较过，没深入探究倒也罢了，只要稍微认真一点，就得掉入 “无所适从” 的尴尬境地。

 我们其实已经用了一些英文词典里的音标中并不存在的符号才能把一些细节讲清楚，比如，阻塞音符号 <span class="pho">◌̚</span>，比如，比央元音更弱的一个音， <span class="pho">ɤ</span>，再比如喉塞音 <span class="pho">ʔ</span>…… 可即便如此，英文有那么多的单词（几十万个），有至少 7,000 个左右构成独特的音节，于是，无论如何都不大可能用一个并不完美的音标系统完美地标注任何自然语音。
 
+## 4.2.4. 背单词的方法
+
+在第三章《音素详解》中，在每个小节，针对每个音素都罗列出了 “常见拼写” —— 这才是未来扩充词汇的时候，最有效的辅助记忆手段和工具。
+
+英文的词汇构成，主要分为 “表音” 和 “表意” 两种。
+
+```mermaid
+flowchart LR
+spellings(拼写) <-.->|拆分| syllables(音节) <-.->|组合| sounds(发音)
+spellings <--> sounds
+spellings(拼写) <-.->|拆分| parts(含义) <-.->|组合| sounds(发音)
+```
+
+*apple* <span class="pho alt">ˈæp.əl</span><span class="speak-word-inline" data-audio-us-male="/audios/apple-us-male.mp3" data-audio-us-female="/audios/apple-us-female.mp3"></span> 就是一个表音构成的词汇，这是两个音节的词汇，app 对应着第一个音节 <span class="pho alt">ˈæp</span>，le 对应着第二个音节 <span class="pho alt">əl</span>。所以，记忆它的时候，不是一个字母一个字母地背，说，“a、p、p、l、e…… apple!”。而是，<span class="pho alt">æ</span> 对应着 a；app，<span class="pho alt">p</span> 的拼写是两个叠加的 *pp*，而后是 *le* 读作 <span class="pho alt">əl</span> —— 这样的拼写很常见，比如，*double*, *impossible*……
+
+而 *impossible* <span class="pho alt">ɪmˈpɑː.sə.bəl</span><span class="speak-word-inline" data-audio-us-male="/audios/impossible-us-male.mp3" data-audio-us-female="/audios/impossible-us-female.mp3"></span> 这个词里，就有表意的构成，*im*- 是个常见词头（prefix），和 *un*- *ir*- 一样，表示否定的含义，*possible* 是 “可能的”，*impossible* 就是 “不可能的”。进而，*possible* <span class="pho alt">ˈpɑː.sə.bəl</span><span class="speak-word-inline" data-audio-us-male="/audios/possible-us-male.mp3" data-audio-us-female="/audios/possible-us-female.mp3"></span> 就可以把它完全当作只有表音构成的词汇，po 读作 <span class="pho alt">ˈpɑː</span>，或者反过来，<span class="pho alt">ˈpɑː</span> 写作 po，ssi ⭠⭢ <span class="pho alt">sə</span>，ble ⭠⭢ <span class="pho alt">bəl</span>…… 反正不应该是 “p、o、s、s、i、b、l、e…… possible!”…… 生硬地按顺序记住 7 个字母，显然不如 “只记三个音节” 来的容易 —— 这其中，需要多注意一下的，不过是 ss（double s）而已。
+
+词根词缀，在词汇量没达到一定程度之前，实际用处不大 —— 但，到了一定地步，比如，词汇量超过 5,000 的时候，在这样扎实的基础上，稍微研究一下词根词缀，对快速且大量地做大词汇量是很有帮助的。
+
+举个例子，*ichthyosaur* <span class="pho alt">ˈɪk.θiə.sɔːr</span><span class="speak-word-inline" data-audio-us-male="/audios/ichthyosaur-us-male.mp3" data-audio-us-female="/audios/ichthyosaur-us-female.mp3"></span>，这个一看就知道并非常用的词汇，其实很简单，先从表音构成去看，<span class="pho alt">ˈɪk.θi.ə.sɔːr</span> —— 剑桥词典把它划分成了 4 个音节…… 但感觉上，第二第三个音节可以合并，<span class="pho alt">ˈɪk.θiə.sɔːr</span>，ich ⭠⭢ <span class="pho alt">ˈɪk</span>, thyo ⭠⭢ <span class="pho alt">θiə</span>, saur ⭠⭢ <span class="pho alt">sɔːr</span>…… 而从表意的角度去看呢？前半部 ichthyo- 的意思是 “与鱼有关的”…… 后半部 -saur 是什么意思呢？各种恐龙的 “龙” 都是 -saur 结尾，于是，这个词的意思是 “鱼龙”……
+
+刚开始的时候，记忆单词无论如何都是吃力的。这是一个真诚的忠告，谁不信谁吃亏，爱信不信：
+
+> 千万不要尝试用任何手段去提速……
+
+—— 因为事实上谁都不可能提速，无论什么手段都不可能提速…… 真正提速的方法只有一个，**积累**。原理上，你掌握的词汇越多，记忆新词的难度就越低…… 整个看似来是个复利曲线一样有加速度的过程，到最后，真的能做到 “看一眼就记住了” 的地步。
