Anyone who has ridden on a railroad train knows how rapidly another train【36】by when it is

traveling in the【37】direction and conversely how it may look almost【38】when it is moving in the same direction.【39】a train at a station starts to move forward【40】gently that passengers feels no backward movement【41】.Then if they happened to【42】the window and see another train slide past on the next track, they have no way of knowing【43】train is in motion and which is at rest;【44】can they tell how fast either one is moving or in which direction The only way they can judge their【45】is by looking out the other side of the car for some fixed body of reference【46】the station platform. or a single fight. Newton was【47】these tricks of motion, only he thought in terms of ships. He knew that on a calm day at sea a sailor can shave himself or drink soup as【48】as when his ship is lying motionless in harbor. The water in his basin, the soup in his bowl, will remain【49】whether the ship is making five knots, 15 knots or 25 knots. So【50】he looks hard at the sea it will be【51】for him to know how fast his ship is moving or indeed if it is moving at all. Of course, if the sea should get rough or the ship changes course suddenly,【52】he will sense his state of motion. But even supposing that we have the idealized conditions of a glass calm sea and a silent ship, nothing that happens below decks -- no amount of observation or mechanical experiment performed inside the ship --will reveal its velocity through the sea. The physical【53】based on these facts was formulated by Newton in 1687."The motions of bodies included in a given space , he wrote, "are the same【54】themselves, whether that space is at rest or moves uniformly【55】in a straight line."

You can’t come in touch with it any longer.” When he came out of the hospital, Mr. Clarke said to himself, “I will see another doctor. It’s much easier to find a doctor than to buy a good dog!

Why is there no risk to the customer when a bank prints the customer's name to his cheques

When anyone opens a current account at a bank, he is lending the bank money, repayment of which he may demand at any time, either in cash or by drawing a check in favor of another person. Primarily, the bank-customer relationship is that of debtor and creditor who is which depending on whether the customer's account is in credit or overdrawn. But, in addition to that basically simple concept, the bank and its customer owe a large number of obligations to one another. Many of these obligations can give rise to problems and complications but a bank customer, unlike, say, a buyer of goods, cannot complain that the law is loaded against him.

The bank must obey its customer's instructions, and not those of anyone else. When, for example, a customer first opens an account, he instructs the bank to debit (把……记入借方) his account only in respect of checks drawn by himself. He gives the bank specimens of his signature, and there is a very firm rule that the bank has no right or authority to pay out a customer's money on a check on which its customer's signature has been forged. It makes no difference that the forgery may have been a very skillful one: the bank must recognize its customer's signature. For this reason there is no risk to the customer in the practice, adopted day banks, of printing the customer's name on his checks, ff this facilitates forgery, it is the bank which will lose, not the customer.

When you have a bank account, you ______. ()

A.must always be in credit

B.can't draw any money if you're overdrawn

C.can draw money without notice

D.can't pay money to anyone else

The Chinese have used a method called acupuncture(针炙) to perform. operations for about 4

The Chinese have used a method called acupuncture(针炙) to perform. operations for about 4,000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them.

To learn how to use the needles takes about one month of training. But to be skillful requires greater time. (79) The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.

Today, the Chinese doctors are trying to learn more about acupuncture. (80) They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, Would prevent the pain in the area of the mouth.

A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation but the chemical may make the patient sick for a few hours or a day.

Acupuncture is ______.

A.a medical operation

B.a medical needle

C.a medical technique

D.a medical machine

Passage OneQuestions 46 to 50 are based on the following passage.Recently I attended sever

Passage One

Questions 46 to 50 are based on the following passage.

Recently I attended several meetings where we talked about ways to retain students and keep younger faculty members from going elsewhere.

It seems higher education has become an industry of meeting-holders whose task it is to “solve” problems— real or imagined. And in my position as a professor at three different colleges, the actual problems in educating our young people and older students have deepened, while the number of people hired—not to teach but to hold meetings—has increased significantly. Every new problem creates a new job for an administrative fixer. Take our Center for Teaching Excellence. Contrary to its title, the center is a clearing house(信息交流中心)for using technology in classrooms and in online courses. It’s an administrative sham(欺诈)of the kind that has multiplied over the last 30 years.

I offer a simple proposition in response: Many of our problems—class attendance, educational success, student happiness and well-being—might be improved by cutting down the bureaucratic(官僚的)mechanisms and meetings and instead hiring an army of good teachers. If we replaced half of our administrative staff with classroom teachers, we might actually get a majority of our classes back to 20 or fewer students per teacher. This would be an environment in which teachers and students actually knew each other.

The teachers must be free to teach in their own way—the curriculum should be flexible enough so that they can use their individual talents to achieve the goals of the course. Additionally, they should be allowed to teach, and be rewarded for doing it well. Teachers are not people who are great at and consumed by research and happen to appear in a classroom. Good teaching and research are not exclusive, but they are also not automatic companions. Teaching is an art and a craft, talent and practice; it is not something that just anyone can be good at. It is utterly confusing to me that people do not recognize this, despite the fact that pretty much anyone who has been a student can tell the difference between their best and worst teachers.

46.What does the author say about present-day universities?

A.They are effectively tackling real or imagined problems.

B.They often fail to combine teaching with research.

C.They are over-burdened with administrative staff.

D.They lack talent to fix their deepening problems.

47.According to the author, what kind of people do universities lack most?A.Good classroom teachers.

B.Efficient administrators.

C.Talented researchers.

D.Motivated students.

48.What does the author imply about the classes at present?A.They facilitate students’ independent learning.

B.They help students form closer relationships.

C.They have more older students than before.

D.They are much bigger than is desirable.

50.What is the author’s suggestion for improving university teaching?A.Creating an environment for teachers to share their teaching experiences.

B.Hiring more classroom teachers and allowing them to teach in their own way.

C.Using high technology in classrooms and promoting exchange of information.

D.Cutting down meetings and encouraging administrative staff to go to classrooms. @@

In the United States many have been told that anyone can become rich and successful if he works hard and has some good luck.

Yet, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tries to look as rich and as successful as his neighbors.

The expression was first used in 1913 by a young American by the name of Arthur Momand. He told this story about himself: he began earning $125 a week at the age of 23. That was a lot of money in those days. Young Momand was very proud of his riches. He got married and moved with his wife to a very wealthy neighborhood outside New York City. But just moving there was not enough. When he saw that rich people rode horses, Momand went horse riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.

It was like a race, but one could never finish this race because one was always trying to keep up. Momand and his wife could not do that.

The race ended for them when they could no longer pay for their new way of life. They left their wealthy neighborhood and moved back to an apartment in New York City.

Momand looked around him and noticed that many people do things just to keep up with their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “keeping up with the Joneses”, because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.

Every city has an area where people want to live because others will think better of them if they do. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses, because no matter what one does, Mr. Jones always seems to be ahead.

6. The writer of the selection believes().

B. anyone in the United Sates can become rich if he works hard and has some good luck

C. he can become rich in the future

A. they want to be as rich as their neighbors

B. they want others to know or to think that they are rich

C. they don’t want others to know they are rich

D. they want to be happy

8. It can be inferred from the story that rich people().

A. like to live in apartments

B. like to live in New York City

C. like to live outside New York City

D. like to have many neighbors

9. Arthur Momand used the name “Jones” in his series of short stories because Jones is().

A,. an important name

B. a popular name in the United States

C. his neighbor’s name

D. not a good name

10. According to the writer, it is().
