　　大学英语六级阅读理解练习题和答案：

　　Nearly everyone agrees that money doesn't buy as much as it used to, no matter where you want to spend it. This is certainly true of the paper money that passes so quickly through one's hands. Inflation(通货膨胀) eats away at its buying power just as the steady appetite of waves chews at sand cliffs. But what about coins that seem to do very little except wear out your purses and pockets? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it won't get scratched or worn. Why is this? One reason is that coins, being more durable, fall more readily into a category for collectors. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up.

　　But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1804, the United States mint(造币厂) struck 19,570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to reach the auction market. So what happened to some 19,564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American territory then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates (#￡&). The probable answer to the mystery is that they were melted down—since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What is known is that whoever can come up with one will find himself instantly rich.

　　1. It can be inferred from passage that_______.

　　A. money buys as much as it did before

　　B. money does not buy as much as it did before

　　C. paper money buys more than metal money

　　D. metal money buys more than paper money

　　2. Which of the following is TRUE of a coin?

　　A. The longer it is held, the less valuable it becomes.

　　B. The more it wears out, the more valuable it becomes.

　　C. The less it gets scratched, the less it values.

　　D. The longer it lasts, the more it values.

　　3. According to this passage, one of the rarest coins in the world is made of A. silver B. gold

　　C. copper D. paper

　　4. Coins become more valuable because_______.

　　A. they wear out your purses and pockets

　　B. the price of metal goes up

　　C. they fall more readily into a category for collectors due to their duration

　　D. both B and C

　　5. What really happened to some 19,564 large silver coins?

　　A. They were melted down. B. They were sunk in the Gulf of Mexico.

　　C. It is still a mystery. D. They were stolen by pirates.

　　In the last two hundred years there have been great changes in the method of production of goods. This is now also true of the building industry; for mechanization has been introduced. System building can save both time and money. The principle of system building is that the building is made from a set of

　　standard units. These are either made at the building-site or at a factory. Some designers, in fact, are standardizing the dimensions of rooms. They are made in multiples of a single fixed length, usually ten centimeters. This is called a modular (标准件的) system, and it means that manufactures can produce standardized fittings at a lower cost. The most important fact about system building is its speed. A ten-storey flat, for example, can be completed in four months.

　　There are several new methods of system building. One is the panel method. In this case, the construction company sometimes erects a factory on the site. The walls and floors of the building, called panels, are cast in a horizontal or vertical position. Conduits for electrical wires and sleeves for pipes are cast in the panels when they are being made. The moulds for making these castings are situated all around the building.

　　After the concrete panels are cast, they are allowed to set and harden for a week. Next they are lifted by a tower crane on to any section of the building. There the panels are cemented together at their joints and the floor covering is laid.

　　After the panels have been cemented together, the crane lifts a case into the area. It contains all the fittings to be installed, such as wash-basins, radiators and pipes. Finishing tradesmen, such as plumbers, plasterers, painters and electricians, follow behind to complete the work.

　　In some building developments, in some countries, whole flats with internal features like their bathrooms, bedrooms and connecting stairs, and weighing as much as twenty tons, are carried to the building-site ready-made. A giant overhead crane is used to lift them into position. In the future, this method may become more widespread.

　　21. The main difference between panel method and the method discussed in the last paragraph is_______.

　　A. the latter uses ready-made internal features

　　B. panels are cast in a level position

　　C. the former is used to build walls and floors while the latter to construct bathrooms or bedrooms

　　D. the former is more expensive than the latter

　　22. Which of these statements is TRUE of system building?

　　A. It employs more men. B. It is difficult and dangerous.

　　C. It can save both time and money. D. It means less mechanization.

　　23. According to the passage, the principle of system building is that_______.

　　A. construction methods are safer

　　B. buildings are made from a set of standardized units

　　C. similar buildings can be produced

　　D. all units are produced on the site

　　24. The usual fixed length in the modular system is_______.

　　A. twenty centimeters B. ten millimeters

　　C. fifty centimeters D. ten centimeters

　　25. What lifts the concrete panels onto the building?

　　A. Cranes. B. Man-power.

　　C. Pulleys. D. Hydraulic jacks.
