CSometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form. of asphalt (柏油) roads?Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.64. Which of the following is true according to the first two paragraphs?A. Arian de Bondt got his idea from his boss.B. Large, flat, black surfaces need to be built in cities.C. The Dutch engineer's system has been widely used.D. Heat can also be collected from asphalt roads.

How the Body Keeps the Same TemperatureThe temperature of your body should always be the same if you are fine,no matter whether the weather is hot or cold.That is why the doctor tests your temperature with a thermometer when you are sick.Normally, your body teniperature is ninety-eight point six degrees Fahrenheit.If it is_______(51)than that,it is a stire sign that something is wrong with your body.Your body keeps the same temperature all the time,because it balances the heat it produces and theheat it_______(52)off. It is always burning up food and producing heat.It can produce heat faster when the body needs or give off heat faster when the body becomes too warm.Let's see_______(53) this works.The heat of your body is given off chiefly through the skin.When you feel_______(54),your skin is tight and shows"goose flesh".When you feel chilly,you must_______(55)around to keep warm._______(56)your muscles begin to work,bum up fuel and produce more heat.It is not_______(57)toshiver,so you usually prefer warming up by taking exercise,or put_______(58)more clothes to keep warm。When you get warm,the skin is loose and soft. It is so supplied_______(59)blood that heat is giv-en off rapidly. If you get too warm,you begin to sweat and_______(60)body heat is used in evaporating the, moisture in your body.In warm_______(61)or warm rooms,you wear less clothing,_______ (62)heat can be given off freely. You prefer less exercise because your body is warm_______(63),and the extra heat produced by taking too much exercise makes you uncomfortable.Now you see why you_______(64)differently in different kinds of weather. In summer,when it is hot,you feel tired and lazy.You do not care to work or play,but enjoy lying down and doing nothing. When you get out of door in winter,the cold air makes you feel_______(65).You want to run and play._________(61)A:weatherB:climateC:circumstanceD:environment
