He went over his instructions in his mind. The agent would appear at four o' clock. He would chat to Lane for a while, after which he would get up, leaving his newspaper behind. The plan would be fastened inside.
A distant clock began to strike the hour. As if from nowhere, a man appeared and sat down be side Lane, placing his newspaper on the seat between them. He was thin and middle-aged, and seemed in need of a good meat. He bored no resemblance to Lane' s idea of a successful spy. His conversation, confined to trivial observations about the weather, was painfully uninteresting.
A few minutes later he got up and continued on his way. Large picked up the paper which laid on the bench, as if he wanted to look at the news. He was excited to see the plans pinned to the center page. At that moment, however, there was a strong wind which lifted the newspaper into the air, like a kite, and blew it into the river.
Lane ______.
A．memorized his orders
B．recited his orders
C．tried to remember his orders
D．repeated his orders himself
When I was young, every Indian had at least three names during his lifetime. His first name was given to him at birth. It described something that had happened at that time.
Each Indian was supposed to keep his birth name until he was old enough to earn money for himself. But his friends would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen.
The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned he would be given his tribal name by the chief. If he had done well, he would be given a good name. But if he had done poorly, he might be given a bad name.
A man was given many chances to improve his name, however. If in a later battle he was very brave in fighting against the enemy, he was given a better name. Some Indians had as many as twelve names - all good and each better than the last.
All names given to one Indian belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away. This was because no man could pass on his name unless the chief and the tribe asked him to do so.
According to passage, Indian names were important because they ______.
A．described the character of a man
B．described the appearance of a man
C．were never used by other people
D．told us his profession
A.a bank is closed for one or more days
B.too many depositors try to draw out their money at one time

Sitting in a dark theater, watching the images on the screen, they enter another world that is real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to be more romantic (浪漫的) and beautiful than in real life.
The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world. American movies are popular because they tell stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can't. People have to cope with many problems and much trouble in real life, so they feel encouraged when they see the" good guys "win in the movies.
The Americans go to the movies mainly because they want______.
A．to enjoy a good story
B．to experience an exciting life
C．to see the actors and actresses
D．to escape their daily life
Not only did the Indians appear to lack a formal system of authority, but they also deeply hated any efforts to control their actions. All members of the tribes knew what was required of them by lifelong familiarity with the tasks of the area. These tasks tended to be simple, since the Indian's rate of social change was slow. Thus, although subgroups such as soldiers had recognized leaders, no real authority was required. Rather than giving direct orders (which were considered rough), members of the tribes would arouse others to action by examples.
It would be difficult, if not impossible, to carry out such a system in our own society. Most of us have grown up under one authority or another for as long as we can remember. Our parents, our teachers, our bosses, our government all have the recognized right under certain conditions to tell us what to do. The authority is so much a part of our culture that it is hard for us to imagine a workable society without it. We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale.
Of course, the major reason why the Indian system would not be suitable for us is that our society is too large. The number of tasks that various members of our society have to perform. often under tight time and resource limitations could not be treated by the Indian system. In modern societies, the formal authority system is necessary to achieve any social objectives.
Which of the following statements is correct according to the passage？
A．From 1710 to 1780, European soldiers came across some Indian groups in the western Great Lakes.
B．European soldiers were quite friendly to the Indian groups.
C．The Indian groups had no leaders.
D．The Indian groups were friendly to each other without a formal leadership system.
The source of the sun' s inconstancy is magnetism. Professor William Livingston has developed new theories about its magnetic nature.
"We don' t yet know what causes sun spots, "he says, "but we now think they ' re areas of high level magnetism that come up from the sun' s interior. So strong is their magnetic pull that the highly ionized gas nearby is not able to transmit energy out. "As a result these areas send out less heat and light and thus appear from Earth to be almost dark irregular surface patches.
Sun spot activity generally fluctuates in steady, 11-year cycled. Scientists have long formed the o pinion that as the size and number of sun spots increased, the overall energy sent out by the sun would de crease. Indeed, recent studies confirmed it, revealing that during peak periods of sun spot activity, the Earth experiences a small drop that can be seen clearly in received solar energy.
Could such a small drop in energy have an effect here on earth？ Perhaps some scientists think the world temperature could fall by' as much as 0.2 during periods of high solar magnetism.., enough to cause significant fluctuations in weather patterns.
According to the passage, it is believed that the sun ______ ．
A．moves in a quick but steady way year after year
B．sends out less and less heat and light with each passing year
C．radiates the same amount of light every year
D．might have a strong influence on the weather patterns
A．detected
B．caught
C．disclosed
D．revealed
A. ease competition among themselves
B. lower their operational costs
C. avoid complaints from consumers
D. provide better online services
