Mending a Puncture(補(bǔ)車胎)

                            Mending a Puncture
     The other day found the front tyre of my bicycle was flat. There was a puncture in the tyre. I always insist on doing everything on my own, so I decided to repair the puncture by myself.
     First, I got my bicycle puncture-repair kit, and found what I wanted: a tube of glue, some chalk and some rubber patches. In addition, I got a bucket full of water.Second, I took the wheel off the bicycle, leveled off the tyre and took out the inner tube. Thlrd, I partly pumped up the inner tube and then submerged it, section by section, in the water to see where the puncture was. When a stream of bubbles were rising, I knew where the puncture was. Fourth, I dried and cleaned the surface of the inner tube. Then marked the hole with the chalk, applied some glue to the surface of the inner tube and to one of the rubber patches, and pressed the rubber patch firmly over the hole. Finally, I pushed the inner tube back inside the tyre of the bicycle wheel, and pumped up the tyre until it was hard.
     That was the whole repairing process.

    補(bǔ)車胎
    一天我發(fā)現(xiàn)我的自行車前輪胎癟了，那上面有一個小洞，我一貫堅持自己的`事情自己做，因此，我決定自己來補(bǔ)這個孔。
    首先，我拿來修補(bǔ)車胎的工具箱，我找到了一管膠水，一些粉筆和一圈能用來作補(bǔ)丁的橡皮片，此外，我又打來滿滿一桶水；第二步，我倒置自行車車輪，扒開外帶取出內(nèi)胎；第三步，我給內(nèi)胎充上氣，然后把它放到水里，一段一段地檢查小孔的位置，當(dāng)一串泡沫顯出來時，我知道小孔就在那里；第四步，我擦干凈內(nèi)胎表面，然后用粉筆在有孔的地方作了標(biāo)記；之后，我往孔的周圍內(nèi)胎及備用的一塊膠帶上涂膠，用力將膠帶壓在刺孔處，最后，我將內(nèi)胎裝好，當(dāng)它牢固時給輪胎充足了氣。
    這就是補(bǔ)車帶的全過程。
