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.

补车胎 一天我发现我的自行车前轮胎瘪了，那上面有一个小洞，我一贯坚持自己的事情自己做，因此，我决定自己来补这个孔。 首先，我拿来修补车胎的工具箱，我找到了一管胶水，一些粉笔和一圈能用来作补丁的橡皮片，此外，我又打来满满一桶水；第二步，我倒置自行车车轮，扒开外带取出内胎；第三步，我给内胎充上气，然后把它放到水里，一段一段地检查小孔的位置，当一串泡沫显出来时，我知道小孔就在那里；第四步，我擦干净内胎表面，然后用粉笔在有孔的地方作了标记；之后，我往孔的周围内胎及备用的一块胶带上涂胶，用力将胶带压在刺孔处，最后，我将内胎装好，当它牢固时给轮胎充足了气。 这就是补车带的全过程。
