今天小編為大家準備了比較實用的英語口語對話，希望對大家有所幫助，接下來跟小編一起來看看吧。 　　A: You come back so earlly. The party is boring? 你回來的這么早。舞會沒意思? 　　B: All the boys and girls were dancing at the party while I sat at a tablealone, feeling like a fifth wheel.晚會上，所有的男孩和女孩都在跳舞，只有我孤零零地坐在桌邊，感覺自己仿佛是一個多余的人。 　　雖然現(xiàn)在很多機車，特別是越野車的后面也會備上一個備用輪胎，但它們稱之為spare wheel,或者spare tyre. 而不能稱為the fifthwheel. 　　更多例句： 　　The chair is a fifth wheel, please take it away. 這把椅子是多余的，請把它搬走。 　　A mother-in-law on a honeymoon is a fifth wheel. 度蜜月時，丈母娘是個大電燈泡。

　　We decided to fire that worker, he was just a fifth wheel.我們決定開除那個工人，他不過是個多余無用之人。 　　My son asked me to come help at his school track meet I felt fifth wheelwhen I got there: they already had enough people to help so I stood therefeeling useless.我的兒子要我在他學校開運動會的時候去幫忙?？墒?，我到了那里覺得自己似乎是多余的，他們已經(jīng)有好多人在幫忙，我只好站在那里沒事干?！?#13; 　　有關the fifth wheel的用法我們暫時了解到這里，記得一定要和sparewheel進行區(qū)別。它們分別表示“無用的;局外人”和“備用輪胎”。
