8 阅读理解。 We have all experienced days when everything goes wrong. A day may begin well enough, but suddenly everything seems to get out of control. It seems as if 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 means your troubles are beginning. While you are on the phone, the baby pulls the table-cloth off the table, destroying your half prepared meal.

The woman driver behind the two cars happened to be a learner. She suddenly go into a panic (恐慌) and stopped her car. This made the driver following her stop suddenly. His wife was sitting beside him holding a large cake. As she was thrown forward, the cake went right through the window and landed on the road. Seeing a cake flying through the air, a truck-driver had to stop his truck all of a sudden. The truck was carrying empty beer bottles and hundreds of them slid off the back of the truck on to the road. This led to yet another angry argument. Meanwhile, the traffic piled up behind. It took the police nearly an hour to get the traffic on the move again. In the meanwhile, the truck-driver had to sweep up hundreds of broken bottles.

10 我们常说液体蒸发时要吸热，如果深入一点想：液体蒸发时从哪里吸热呢？是从外界（液体周围的物体）吸热，还是从液体内部（本身）吸热呢？回答是：从液体内部（本身）吸热．由于液体蒸发时从本身吸热，因而使自身的温度下降；当液体的自身温度比外界（周围物体）的温度低时，液体就要从外界吸热，使外界的温度也下降．这就是蒸发致冷作用．医生用酒精棉球擦病人的皮肤消毒时，被擦的地方感到凉，下列解释正确的是 A.酒精蒸发时从皮肤吸热，皮肤温度下降，酒精温度升高 B.酒精蒸发时从酒精吸热，酒精温度下降，皮肤温度也下降．
