華為二公主姚安娜籤約出道的首支單曲，名字就叫《Backfire》。
back + fire，字面意思是後面冒火，一般指汽車引擎燃燒不順暢，從排氣管排出的異常爆響。
Use the word backfire when you talk about the sound a car makes when a small explosion in its exhaust system pops — sometimes as loudly as a gunshot.
Hearing a car's backfire can make you jump, because it makes a sharp, shot-like sound. A backfire is usually caused by unburned fuel, and it can be accompanied by a burst of flame and a brief loss of power in the vehicle, as well as a fairly loud noise.
這個單詞，最開始指的是一種頗特殊的滅火方法。當發生森林大火，火勢失去控制時，在火勢延燒的.方向的前方，除了清出一條防火巷(fire alley)之外，並且引燃另一場火，讓它燒回去（burn back）。兩股火勢碰頭時，也就是燃料燒盡而不得不熄滅的時候。可是這種方法有它的危險性，就是新點燃的火要能完全掌握，場地和環境等要整理得很徹底。不然就很可能把一場火災變成兩場火災。
The word comes from an American English term that originally referred to a fire deliberately set to slow the progress of a prairie or forest fire.
「以火滅火」，如果沒能滅火，反而越燒越旺，就會弄巧成拙了。因此，backfire 也喻指：事情沒有按照原定計劃發展，收到了相反的效果。這裡目前backfire最常用的含義。
另外，有一個與 backfire 構造很象的詞：backlash，表示反撲，好象你去鞭打(lash)對方，結果對方起而反撲，奪去鞭子反過來鞭打你一樣。When many people react against something in the same way, you can call it a backlash. A backlash against government policies can result in mass protests.
When people get angry enough about something — or just tired of hearing about it — the result can be a backlash. An influx of refugees to a city can cause a backlash against immigration, and the popularity of a particular style of music might eventually cause a backlash against it. A true backlash involves many people acting together. The original, 1815 meaning of backlash was "recoil between parts of a machine." It wasn't until the 1950's that the figurative meaning came into use.
lash：鞭打。A lash is a sharp slap or strike with a rope or whip. In some parts of the world, lawbreakers receive a certain number of lashes as punishment for their crimes.
注意，新加坡的鞭刑，英文是： caning，是 cane 這個詞的動詞形式。
cane是手杖、藤條的意思，本身也有動詞的意思：用荊條打。而 sugarcane 就是：甘蔗。
我們回到 lash。eye+lash 構成 eyelash，意思就是 眼睫毛。
splash：潑灑。A splash is a tiny amount of a liquid. You might, for example, prefer your coffee with just a splash of cream. A splash can be wet, like a splash of lemonade in your tea, or it can be bright, like a splash of yellow across the oil painting you're working on. You can also use splash as a verb, as when you splash your sunbathing brother with swimming pool water.
Start where you are. Use what you have. Do what you can.
