Passage Two
I am Sergey Brin !I was born in Moscow． In 1979,when I was 5,my family immigratedto the U． S． A． , California． I remember that on my 9th birthday I got my first computer “Commodore 64”．
Later I graduated with honors in the University of Maryland in Mathematics and IT． The main field of my science research was the technologies used to collect data from unsystematic sources as well as large quantities of texts and science data． I was the author of dozens of articles in leading American academic magazines．
The greatest event in my life happened in 1998 when I was preparing for the defense(论文答辩) of my Doctor's degree in Stanford University． There the fate made me meet Larry Page-a young computer genius． Larry belonged to the inteilectual（知识分子）society．Larry and I quickly became friends when we worked together．
We were searching day and night on the Internet． We were finding a lot of information but with the feeling we still couldn't find enough of what we were looking for． Naturally the idea for a search engine that would allow specific information to be found in the endless pool of data was born like it came to us． It wasn't our plans but we gave up the education at the university． You know the next part,maybe-we managed to turn an ordinary garage in Meplo Park,California,the U． S． A． into our first of．fice,in which Google was born． With excitement we typed the name of the thing which we created with love on September 14th, 1998—www． Google． com． Now,after those years we bought this garage． As a symbol it will always remind us that everything is possible．
Which of the following would be the best title for this passage？ ()

C
As Internet users become more dependent on the Internet to store information， are people remember less？ If you know your computer will save information， why store it in your own personal memory， your brain？ Experts are wondering if the Internet is changing what we remember and how.
In a recent study， Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment， they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later， the second group remembered the information better. People in the first group knew they could find the information again， so they did not try to remember it.
In another experiment， the researchers gave people facts to remember， and told them where to find the information on the Internet. The information was in a specific computer folder （文件夹）. Surprisingly， people later remember the folder location （位置） better than the facts. When people use the Internet， they do not remember the information. Rather， they remember how to find it. This is called "transactive memory （交互记忆）"
According to Sparrow， we are not becoming people with poor memories as a result of the Internet. Instead， computer users are developing stronger transactive memories； that is， people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn‘t mean we are becoming either more or less intelligent， but there is no doubt that the way we use memory is changing.
根据材料回答64-67题。 The passage begins with two questions to ______.
A.introduce the main topic
B.show the author"s altitude
C.describe how to use the Interne.
D.explain how to store information
第5题
Sal's卫星公司向纽约和洛杉矶的订户发送电视节目。两地订户群体的需求曲线分别为:
(1)纽约市场和洛杉矶市场的利润最大化价格和数量各是多少？
(2)因为在五角大楼配置了一颗新卫星，洛杉矶人可以接收到Sal's在纽约发送的节目,而纽约人也可接收到Sal's在洛杉矶的播出。这样纽约或洛杉矶的任何人只要在任一城市付费就可收到Sal's的节目。因此Sal's只能定单一的价格。它会定什么价格，以及它在纽约和洛杉矶能销售多大数量呢？
(3)在上面的(1)还是(2)哪种情况下，Sal's是得益的？从消费者剩余的角度，纽约人偏爱哪种情况而洛杉矶人偏爱哪种情况？为什么？
Sal 's satellite company broadcasts TV to subscribers in Los Angeles and New York. The demand functions for each of these two groups are
a. i What are the profit - maximizing prices and quantities for the New York and Los Angeles markets？
b. As a consequence of a new satellite that the Pentagon recently deployed, people in Los Angeles receive Sal's New York broadcasts, and people in New York receive Sal's Los Angeles broad-casts. As a result, anyone in New York or los Angeles can receive Sal’s broadcasts by subscribing in either city. Hence Sal can charge only a single price. What price should he charge, and what quantities will he sell in New York and Los Angeles？
c.In which of the above situations. (a) or (b), is Sal better off？ In terms of consumer surplus, which situation do people in New York prefer and which do people in Los Angeles prefer？ Why？

The manufacturer who increases the unit price of his product by changing his package size to lower the quantity delivered can, without undue hardship, put his product into boxes, hags, and tins that will contain even 4-ounce, 8 ounce, one-pound, two-pound quantities of break fast foods, cake mixes, etc. A study of drugstore and supermarket shelves will convince any observer that all possible sizes and shapes of boxes, jars, bottles, and tins are in use at the same time, and, as the package journals show, week by week, there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation. The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by end less changes of package sizes, materials, shape, art work, and net weights that are used for improving a product's market position.
When a packaging expert explained that he was able to multiply the price of hard sweets by 2.5, from $ 1 to $2.50 by changing to a fancy jar, or that he had made a 5-ounce bottle look as though it held 8 ounces, he was in effect telling the public that packaging can be a very ex pensive luxury, h evidently does come high, when an average family pays about $ 200 a year for bottles, cans, boxes, jars and other containers, most of which can't be used for anything but stuffing the garbage can.
What started the public and Congressional concern about deceptive packaging rumpus'？
A．Consumers' complaints about the changes in package size.
B．Expensive packaging for poor quality products.
C．A senator's discovery of the tricks in packaging.
D．The rise in the unit price for many products.

Natural foods, for example, vegetables, fruits and grains which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for ex- ample, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar, this is actually a non-essential food! Although a natural alternative, such as honey, can be used to sweeten food if this is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be an additive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form. of calories. There are no vitamins in it, no minerals and no fibre.
It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetable. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetable, certain diseases are comparatively rare. Hence the emphasis placed on the eating of wholemeal bread and more vegetables by modern experts on healthy eating.
Recently, some people are interested in natural foods because ______.
A．these foods are fresh and sweet
B．they want to change their eating habits
C．these foods do not contain chemical additives and have not been affected by chemical fertilizers
D．they don't like the processed foods
第8题
The riches of the sea yet to be developed by man ’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.
Technology is enabling man to explore ever deeper under the sea. The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.
What is the best title for the passage？
A.Needs of .Man
B.Sources of..Energy
C.Sea Harvest
D.Sea Exploring Technology
According to the author, technology for exploring the sea is important because______.A.man cannot travel farther into space
B.resources on land are running short
C.it’s a lot of fun diving into the sea
D.ancient people used to explore the sea
Why does the author mention a steamship？A.To indicate that it is warmer in the ocean than on land.
B.To show that a steamship is better than other kinds of ship.
C.To argue that man should use steamships more than other means of transportation.
D.To illustrate that man can make use of sources of energy from the sea.
It can be inferred from the passage that_______.A.man hasn’t completely developed the riches of the sea
B.technology for exploring the sea has been solved
C.planting rice in the sea will be made possible in a short time
D.in the near future man can live on the ocean floor
The word “exploit” in the last paragraph could best be replaced by________.A.evaluate

第9题
It is said that the public and Congressional concern about deceptive (欺骗性的) packaging rumpus (喧嚣)started because Senator Hart discovered that the boxes of cereals consumed by him, Mrs. Hart, and their children were becoming higher and narrower, with a decline of net weight from 12 to 10.5 ounces, without any reduction in price. There were still twelve biscuits, but they had been reduced in size. Later, the Senator rightly complained of a store-bought pie in a handsomely illustrated box that pictured, in a single slice, almost as many cherries as there were in the whole pie.
The manufacturer who increases the unit price of his product by changing his package size to lower the quantity delivered can, without undue hardship, put his product into boxes, bags, and tins that will contain even 4-ounce, 8-ounce, one-pound, two-pound quantities of breakfast foods, cake mixes, etc. A study of drugstore (杂货店) and supermarket shelves will convince any observer that all possible sizes and shapes of boxes, jars, bottles, and tins are in use at the same time, and, as the package journals show, week by week, there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation. The producers of packaged products argue strongly again st changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by endless changes of package sizes, materials, shape, art work, and net weights that are used for improving a product's market position.
When a packaging expert explained that he was able to multiply the price of hard sweets by 2.5, from $1 to $ 2.50 by changing to a fancy jar, or that he had made a 5-ounce bottle look as though it held 8 ounces, he was in effect telling the public that packaging can be a very expensive luxury. It evidently does come high, when an average family pays about $ 200 a year for bottles, cans, boxes, jars and other containers, most of which can’t be used for anything but stuffing the garbage can.
What started the public and Congressional concern about deceptive packaging rumpus？
A．Consumers' complaints about the changes in package size.
B．Expensive packaging for poor quality products.
C．A senator’s discovery of the tricks in packaging.
D．The rise in the unit price for many products.

The Basics of Import and Export
Importing and exporting is transferring goods from one country to another while paying attention to the laws and requirements of bringing goods out or into that country. If you want to import in large quantities for commercial purposes, you’ll need to have the consent of the local customs department and the right paperwork. Import and export are the basics of international trade. If you are looking forward to starting your own business in the field of importing and exporting business then here are some tips for starters.
Foreign embassies provide nice programs and a great deal of information about their goods to promote exporting. You can find out exactly what it is you are looking to buy. If you are exporting, you can approach your local department of trade and see what plans they have on offer to promote exports. Besides, you should consult the tax department to find out if there is a particular process to setting up an importing and exporting company and what documentation you will require. It is also necessary that you find out about any licensing requirements for importing and exporting of goods. Some countries do not allow their goods to go to a certain country and vice versa, this is known as an embargo. In this way, you can make sure that there are no embargoes with the country you are looking to trade with.
1. International trade refers to both import and export.
2. Only after the local customs department agrees, could you start your own business in the field of import and export.
3. Foreign embassies do nothing to help promote exporting.
4. If you are exporting, you can turn to no one for help.
5. Some countries do not allow their goods to go to a certain country.
