The scientist's knowledge must be exact.There is no room for half right or right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions.This is one reason that investigations are important in science.Albert Einstein,who developed the theory of relativity,arrived at this theory through mathematics.The accuracy of this mathematics was later tested through investigations,Einstein's ideas were shown to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.

"We're more than halfway (中途) now; it's only two miles farther to the tavern (客栈) ," said the driver.
"I'm glad of that," answered the stranger, in a more sympathetic way. He meant to say more but the east wind blew clear down a man's throat if he tried to speak. The girl's voice was quite attractive; however, later he spoke again.
"You don't feel the cold so much at twenty below zero in the Western country. There isn't such damp chill (潮冷)", he said, and then it seemed as if he had blamed the uncomplaining young driver. She had not even said that it was a bad day, and he began to be conscious of a warm hopefulness of spirit, and sense of pleasant adventure under all the woolen scarves.
"You'll have a cold drive going back," he said anxiously, and put up his hand for the twentieth time to see if his coat collar was as close to the back of his neck as possible.
"I shall not have to go back!" cried the girl, with eager pleasantness. "I'm on my way home now. I drove over early just to meet you at the train. We had word that someone was coming to the tavern."
How far was the drive from the train to the tavern？
A．One mile.
B．About four miles.
C．Two miles.
D．Less than four miles.
A prescription is as personal as your name. It is designed for you alone. It is based on such factors as your age, weight, general health, allergies (过敏症), and other factors, as well as your illness.
Never take a prescription drug meant for another person, even if you think you have the same illness. Prescriptions aren't supposed to be traded around the family or neighborhood. Each prescription is intended for an individual. It is a violation of federal law to sell a prescription drug without a prescription.
Doctors and dentists are licensed by each state to prescribe drugs for human use. Doctors for veterinary (兽医的) medicine are licensed to prescribe drugs for animal use.
A licensed medical doctor must pass all examination m practice medicine in a certain state. Before doing this, he or she has probably completed at least two years of a premedical course, a four-year medical course, two years of internship (实习) or residency in a hospital, and perhaps an extra year or more of training in a specialty -- altogether at least eight years of medical training, possibly nine.
Don't take prescriptions written for you during a previous illness without first checking with your doctor. Your illness may not be the same as the previous one, even though you think it is. Also the drug may have lost strength. Only a doctor is qualified to advise you about continuing to take a medicine.
Why does the law require that some drugs be used under a doctor's prescription？
A．Because they are not safe.
B．Because they need further special tests.
C．Because they are meant to cure serious diseases.
D．Because the prescription can ensure the safe use of the drugs.
听力原文： All warm-blooded animals are very helpless at first. Young birds and young bats must be taught to fly. Thousands of young seals drown every year. They never learn to swim "naturally." The mother has to take them out under her flipper and show them how. Birds sing without instruction; however, they do not sing well unless they are able to hear older members of their species. Older harvest mice build better nests than beginners. Frank Buck says that the young elephant does not seem to know at first what his trunk is for. It gets in his way and seems more of a hindrance than a help until his parents show him what to do with it. Insects, seem to start life equipped with all necessary reflexes, but they seem to improve their talents with practice. Young spiders, for example, begin by making quite primitive little webs. They attain perfection in their art only after much time. Older spiders, if deprived of their spinnerets, will take to hunting.

B．They know how to fly naturally.
C．They often reject their parents.

Dear Mr. Mills,
In reply to your letter of April 20, I would【21】to inform(通知) you that there are a【22】of beautiful summer cottages(小别墅) for sale here in Ocean City.
For example, we have a modern two-storey house that is【23】up to date. It is two blocks from the sea and you may find this a disadvantage(不利), but,【24】all, the opening of the summer【25】is only a few weeks from now, and finding a house【26】to the ocean than that is【27】out of the question. The house I'm speaking of has two bedrooms and a porch(门廊) that can be【28】for sleeping. For this reason, I consider it as a very good buy. The plumbing(给水管道) is out of order at the【29】, but this will be repaired, of course. The price is reasonable; as a matter of fact, it is less than is being asked for comparable(同等的) houses elsewhere in town.
As a rule, I【30】 to deal with people face to face in matters of this kind.【31】, I will be out of town next week, and I don't think you should delay in【32】 your decision about this house, since it is sure to be sold quickly. Under the circumstances (环境),【33】, I suggest that you come to see it as【34】 as possible. You can deal with one of my assistants in the office. I am sure you will find the house is【35】 what you expect.
Sincerely yours,
Jason Riggs, Manager
Ocean City Real Estate Company

为：M/P=L(r，Y)。这里：P=λPd+(1-λ)Pf/e，参数λ是物价指数P中国内产品的比例。假设国内产品价格Pd和用外国通货表示的外国产品价格Pf是固定的。
a．假定我们根据Pd与Pf给定的值(而不是通常所用的P)画出LM*曲线。解释为什么在这个模型中这条LM*曲线向右上方倾斜，而不是垂直的。
b．在这个模型中，在浮动汇率下，扩张性财政政策的影响是什么？请解释。与标准的蒙代尔—弗莱明模型进行对比。
c．假设政治不稳定提高了该国的风险贴水，从而使利率上升。在这个模型中，对汇率、物价水平和总收入的影响是什么？与标准的蒙代尔—弗莱明模型进行对比。
Suppose that the price level relevant for money demand includes the price of imported goods and that the price of imported goods depends on the exchange rate. That is, the money market is described by M/P=L(r，Y)，where P=λPd+(1-d)Pf/e. The parameter λ is the share of domestic goods in the price index P. Assume that the price of domestic goods Pdand the price of foreign goods measured in foreign currency Pfare fixed.
a．Suppose we graph the LM*curve for given values of Pdand Pf(instead of the usual P). Explain why in this model this LM*curve is upward sloping rather than vertical.
b．What is the effect of expansionary fiscal policy under floating exchange rates in this model？ Explain. Contrast with the standard Mundell-Fleming model.
c．Suppose that political instability increases the country risk premium and，thereby，the interest rate. What is the effect on the exchange rate, the price level, and aggregate income in this model？ Contrast with the standard Mundell-Fleming model.
