油罐漏油的原因？

We have all experienced days when everything goes wrong. A day may begin well enough, but suddenly everything seems to get out of control. Sometimes a single unimportant event may cause a number of things to happen. Let us suppose that you are preparing a meal and keeping an eye on the baby at the same time. The telephone rings and this causes your troubles to begin. While you are on the phone, the baby pulls the tablecloth off the table, destroying your half-prepared meal. You hang up hurriedly and attend to your baby. Meanwhile, the meal gets burnt. As if this is not enough to bring you to tears, your husband arrives home, unexpectedly bringing three guests to dinner.

Things can also go wrong on the road. During rush hour one evening two cars collided and the drivers began to argue. The woman driver behind the two cars happened to be a learner. She got into a panic and stopped her car. This forced the driver following her to stop suddenly. This driver’s wife was sitting beside him holding a large cake, and as she was thrown forward, the cake went right through the window and landed on the road. A truck driver seeing a cake flying through the air slammed on the brakes. The truck was carrying empty beer bottles and hundreds of them slid off the back of the truck onto the road, causing a terrible traffic jam. It took the police an hour to get the traffic on the move again. In the meantime, the truck driver had to sweep up hundreds of broken bottles. Only two dogs were enjoying themselves, for they were happily having what was left of the cake.
