Third wheel, 第三個(gè)車輪？

No.自行車、摩托車、馬車、手推車一般都是兩個(gè)車輪。再加一個(gè)車輪就多余了，沒(méi)什么用。

汽車、卡車一般都是4個(gè)車輪。再加一個(gè)車輪就多余了，沒(méi)什么用。

因此，third wheel, fifth wheel就是多余的，無(wú)用的。等同于我們中文經(jīng)常說(shuō)的“當(dāng)電燈泡”，不該出現(xiàn)的場(chǎng)合。比如，My sister will go to Florida with? her fiancé for a vacation. They asked me to go with them. I believe their invitation is just for? politeness. I gave them an? excuse not to go as I do not? want to be a third wheel(fifth? wheel).我妹妹和她男朋友要去佛羅里達(dá)度假。他們邀請(qǐng)我去。我相信他們是出于禮節(jié)。我不想當(dāng)電燈泡，找了個(gè)借口謝絕了。

2021年的情人節(jié)（Valentine’s Day）,yahoo刊登了如下報(bào)道：

來(lái)自《世界時(shí)裝之苑》

Selena Gomez法律上是單身，到處約會(huì)，當(dāng)電燈泡和她最好的伙伴度過(guò)情人節(jié)。
