His name was Alfred Nobel. He was a great scientist and inventor himself. Besides, he had a big business. His business may surprise you. He made and sold explosives. His companies even made and sold weapons. Isn’t this something that surprises you? The man who made money from weapons should set up the Peace Prize?Though Alfred Nobel had a lot of money from weapons, he hated war. He hoped that there would be no war in the world. He was one of the richest in Europe. When he died in 1896, he left behind him a lot of money and his famous will. According to his will, most of his money was placed in a fund. He wanted the interest from the fund to be used as prizes every year. We know them as the Nobel Prizes. The Nobel Prizes are international. Alfred Nobel wanted the winners to be chosen for their work, not the country they came from.Alfred Nobel had given his whole life to his studies and work and to the benefits of mankind. He made money all by his own efforts, but he left the world share his wealth. His inventions and wealth stay with the world for ever.61. Alfred’s business was _____.A. making and selling explosivesB. not making and selling weaponsC. making explosives and selling weaponsD. making weapons and selling explosives62. Nobel wanted to set up the Nobel Peace Prize because _____.A. he made enough moneyB. he hated warC. he wanted to get more interest from the fundD. he liked to live in a peaceful world63. Nobel Prizes come from _____.A. all Nobel’s money in the fundB. all Nobel’s money in his companyC. all the interest from the fundD. some of the interest in the fund64. Nobel was a (an) _____ person in the world.A. interestingB. unselfishC. kind-heartedD. richest65. Which statement of the following is Right according to the passage?A. Nobel set up his company to sell clothes.B. Most of Nobel’s money was used for the world Wars.C. Nobel Prizes are only for some people from some special countries.D. Nobel worked hard in his life and saved lots of money for the world to share.Passage 2Dinner customs are different around the world. If you are a dinner guest in Ghana, this information will help you a lot.In Ghana dinner is usually from four in the afternoon to six in the evening. But there are no strict rules about time. Whenever a guest arrives, a family offers food. When you go to a home, the person who receives guests takes you to the living room first. At this time everyone welcomes you. Then you go to the dining room. There you wash your hands in a bowl of water. All the food is on the table.In Ghana you usually eat with your fingers. You eat from the same dish as everyone else. But you eat from one side of the dish only. It is not polite to get food from the other side of the dish. After dinner, you wash your hands again in a bowl of water.Most meals in Ghana have a dish called fufu. People in Ghana make fufu from the powder of some plants. Sometimes they cut the fufu with a saw because it is very hard. You must chew fufu well, or you may get sick. You eat fufu with the fingers of your right hand only.66. From the passage we know that in Ghana _____.A. the rules for dinner time are not strictB. dinner is always at six in the eveningC. a family offers food only at four in the afternoonD. people usually invite their guests to dinner later in the evening67.If you are a dinger guest in Ghana ,the host(主人)always takes you to _____.A. the dining room firstB. the living room firstC. the kitchen firstD. the garden first68 People in Ghana usually eat _____.A. from one side of a dish to the otherB. from the other side of the dishC. with their fingersD. with their spoons69. In fact, most dishes in Ghana _____.A. are cooked with the powder of some plantsB. have fufu in themC. are too hard to eatD. are very hard70. When you eat fufu, you’d better _____.A. cut it with a sawB. use your right hand onlyC. chew it wellD. all of the abovepassage 3Most people usually traveled by ship and train which are driven by steam engine. It played an important part in many kinds of vehicles several scores of years ago. Who invented steam engine and what units could be used to measure the power of engine？The word “horse-power” was first used two hundred years ago. James Watt from a worker’s family made the world first widely used steam engine. At first, he couldn’t tell people how powerful it was, because there were no units at that time. Watt decided to find out how much work one strong horse could do in one minute. He named that unit one horse-power. In this way he could measure the work of his steam engine.He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute. His engine could lift a 3300-pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten horse-power engine.71. The main idea of the passage is ___.A. James Watt invented the steam engineB. James Watt first used horse-power as a unit of measureC. how much power does a horse haveD. why Watt’s engine is called a ten horse-power engine72. The story says that Watt made the first ____.A. engineB. horse-power engineC. useful engineD. widely used steam engine73. James Watt was born in ____.A. a worker’s familyB. a farmer’s familyC. a teacher’s familyD. a doctor’s steam engine74. Watt wanted to find a way to ____.A. measure the work his engine could doB. tell people how powerful his engine wasC. lift a 3300-pound weightD. both A and B75. One horse-power means the ____.A. work a horse could do in a minuteB. weight a horse could do in ten minutesC. work a horse could do in ten minutesD. weight of one horsePassage 4Another thing an astronaut has to learn about is eating in space. Food is weightless, just as men are.Food for space has to be packed in special ways. Some of it goes into tubes that a man can squeeze into his mouth. Bite-sized cookies are packed in plastic.There is a good reason for covering each bite. The plastic keeps pieces of food from traveling in the spaceship. On the earth very small pieces of food would simply fall to the floor. But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship. They move here and there and can get into a man’s eyes or into the spaceship’s instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home.As astronauts travel on longer space trips, they must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt .Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat. But be careful he must put his hands under the belt when he goes to sleep. This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later.76. Why would astronauts cover each bite of food in space？____A. Because small pieces of food would fall down to the floor.B. Because weightless pieces of food might make trouble when they travel around.C. Because they haven’t enough food for longer trips.D. because astronauts don’t want to waste food.77. In a spaceship, astronauts can ____.A. walk just as they do on the earthB. not eat anything because it’s dangerousC. control the spaceship when they are sleepingD. not litter small things or it will make trouble78. In what way is food for space packed？___A. Very small pieces of food are put on the floor.B. Some of it is put into tubes.C. Small-sized cookies are packed in plastic.D. Both B and C.79. Why does an astronaut put his hand under his belt when he sleeps？____A. Because he thinks it is comfortable to sleep in that way in space.B. Because he doesn’t want to touch any controls when he sleeps.C. Because the instruments of the spaceship are easily broken.D. Because he is afraid that the seat will move.80. The best title of this article is ____.A. Eating and Sleeping in SpaceB. How Astronauts Eat in SpaceC. Food for SpaceD. How Astronauts Sleep in SpacePart IV Translation汉译英：81.过去在路的尽头有一家商店82.只有那时，我才有机会实现我的梦想。

总之，提出古典假定是为了使所作出的估计量具有较好的统计性质和方便地进行统计推断。
2、当异方差出现时，常用的t 和F 检验失效；正确3、解释变量与随机误差项相关，是产生多重共线性的主要原因。
错误产生多重共线性的主要原因是：经济本变量大多存在共同变化趋势； 模型中大量采用滞后变量；认识上的局限使得选择变量不当；……。

5、由间接最小二乘法与两阶段最小二乘法得到的估计量都是无偏估计。
超纲！错误间接最小二乘法适用于恰好识别方程的估计，其估计量为无偏估计；而两阶段最小二乘法不仅适用于恰好识别方程，也适用于过度识别方程。
两阶段最小二乘法得到的估计量为有偏、一致估计。
四、计算题1、为了研究深圳市地方预算内财政收入与国内生产总值的关系，得到以下资料来源:《深圳统计年鉴2002》，中国统计出版社利用EViews估计其参数结果为(1)建立深圳地方预算内财政收入对GDP的回归模型；(2)估计所建立模型的参数，解释斜率系数的经济意义；（3）对回归结果进行检验；(4) 若是2005年年的国内生产总值为3600亿元，确定2005年财政收入的预测值和预测区间(0.05α=)。
