共用题干 Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.We find it hard to break free from ideas connected with living on the earth because______.A:it demands too great an effort for us to do soB:we are too familiar with the way things are to question the ideasC:we have proved that those ideas are correctD:we are so sure of ourselves that we never doubt anything on the earth

Very few of our birds stay with us the year round.Some come to us in the winter from the cold?north.Others come from the south to spend the summer with us.How do they know the way?Suppose?you were told to find your way to a place hundreds of miles away,do you think you could do it? Yet birds travel over mountains,forests,lakes and even across the oceans,and do not stray from?the path.They find their way back in the spring to the same orchard（果园）and the very trees where?they nested the summer before. It is wonderful how quickly birds travel such long distances from their summer homes to their?winter ones.Some birds have been known to fly hundreds of miles in a day.But others travel much?more slowly. Why do birds undertake these long journeys twice a year?Perhaps cold weather and lack of?food drive them from us in the autumn,but we cannot tell why they leave the sunny south to come?back to us in the spring.We know only that many of them like to make their nests and rear their?young in the north. We are sorry to see them go,but we know that when winter is over they will come back to us.In which season do we have most birds to stay with us?A.In spring. B.In summer. C.In winter. D.We don't know.

The process of perceiving others is rarely translated(to ourselves or others) into cold,objective terms．"She was 5 feet 8 inches tall, had fair hair, and wore a colored skirt．" More often, we try to get inside the other person to pinpoint his or her attitudes, emotions, motivations,abilities, ideas, and characters． Furthermore, we sometimes behave as if we can accomplish this difficult job very quickly--perhaps with a two-second glance． We try to obtain information about others in many ways． Berger suggests several methods for reducing uncertainties about others; who are known to you so you can compare the observed person's behavior with the known others' behavior, observing a person in a situation where social behavior is relatively unrestrained or where a wide variety of behavioral responses are called for,deliberately structuring the physical or social environment so as to observe the person's responses to specific stimuli, asking people who have had or have frequent contact with the person about himor her, and using various strategies in face-to-face interaction to uncover information about another person--question, self-disclosures, and so on． Getting to know someone is a never-ending task, largely because people are constantly changing and the methods we use to obtain information are often imprecise． You may have known someone for ten years and still know very little about him． If we accept the idea that we won't ever fully know another person, it enables us to deal more easily with those things that get in the way of accurate knowledge such as secrets and deceptions． It will also keep us from being too surprised or shocked by seemingly inconsistent behavior． Ironically, those things that keep us from knowing another person too well (e． g． secrets and deceptions) may be just as important to the development of a satisfying relationship as those things that enable us to obtain accurate knowledge about a person (e． g． disclosures and truthful statement)． There are things that we find preventing us from knowing others． These things are__________．A.disclosures B.deceptions C.stimuli D.interactions

There is no creature that does not need sleep or complete rest every day. If you want to know why,just try going without sleep for a long period of time.You will discover that your mind and body would become too tired to work properly.You would become irritable and find it hard to think clearly or concentrate on your work.So sleep is quite simply the time when the ceils of?your body recover from the work of the day and build up supplies of energy for the next period of activity. One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down. For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do. Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.The cells of your body develop supplies of energy__________A.when you are asleep B.when you recover from your work of the day C.in the next period of activity D.when you are quiet
