世纪百通期末金卷系列答案Alan Izhar-Bodner, an Israeli inventor, has developed a swimming suit for divers to breathe underwater without carrying heavy oxygen tanks. His suit makes use of the air that is dissolved（溶解）in water, just like fish do.
The system uses the Henry Law which states that the amount of gas that can be dissolved in a liquid is proportional (成比例的)to the pressure on the liquid. Raise the pressure ---more gas can be dissolved in the liquid. Decrease the pressure --- less gas dissolved in the liquid releases the gas. This is exactly what happens when you open a can of soda; carbon dioxide gas is dissolved in the liquid and is under pressure in the can. Open the can, releasing the pressure, and the gas fizzes(嘶撕作响)out.
Bodner's System obviously uses a special machine to lower pressure in part of a small amount of seawater taken into the system; dissolved gas is taken out. The patent（专利）reads: A self-contained open-circuit（循环）breathing instrument for use within a body of water naturally containing dissolved air. The instrument is adapted to provide breathable(可吸入的)air. The instrument contains an inlet for taking out a quantity of water from the body of water. It further contains a separator for separating the dissolved air from the quantity of water, thus gaining the breathable air. The instrument further contains an outlet for expelling (驱逐)the separated water back into the body of water, and another outlet for removing the breathable air and supplying it for breathing. The air is supplied so as to enable it to be expelled back into the body of water after it has been breathed .
Human beings have been thinking about how to breathe underwater since they started swimming. This long-held desire plays an important part in one of the first great science fiction novels, Jules Verne's 20,000 Leagues Under the Sea.
【小题1】It can be inferred from the passage that____________ .
| A．the less pressure it is, the less carbon dioxide gas is dissolved in the liquid |
| B．the deeper one dives into the ocean, the less gas is dissolved in the water |
| C．the greater pressure it is, the more carbon dioxide gas is dissolved in the liquid |
| D．the deeper one dives into the ocean, the more gas is dissolved in the water |
| A．how Bodner invented the instrument for breathing underwater |
| B．why Bodner invented the instrument for breathing underwater |
| C．how Bodner's instrument for breathing underwater works |
| D．how Bodner's instrument is used by divers for breathing underwater |
| A．a separator is used to expel breathable air back into the body of water |
| B．a separator is used to separate the air from the water so as to make use of the water |
| C．The breathable air removed from an outlet will eventually go back to the body of water. |
| D．The breathable air removed from an outlet will immediately go back to the body of water. |
Barcodes(条形码) aren’t given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970.
A small food store owner decided one day that keeping records of the inventory(存货) of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem and began working on a solution involving an automatic way of keeping track of items that had been sold. Sliver and a group of students from the institute realized their answer in the form of ultraviolet light (紫外线), ink and a scanner.
The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace（寻常的事）in grocery stores, these two problems had to be solved.
The patent (专利) for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact, it took three years for the patent agency to grant their invention patent for the barcode, occurring on 7th October, 1952.
Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticized, as there was no central mechanism for controlling uniformly（统一地）coded items. In 1970, Logicom developed the Universal Grocery Products Identification code( UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh’s superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared(升温) ever since, and is obviously now commonplace in all types of stores worldwide.
【小题1】What is stressed in the second paragraph?
| A．The heavy work of store owners. |
| B．The function of ultraviolet light, ink and a scanner. |
| C．The origination of barcodes. |
| D．Bernard Sliver’s education background. |
| A．It was expensive to be applied on a large scale. |
| B．It was a laborious process. |
| C．The system was not stable. |
| D．It lacked a central mechanism. |
| A．1948 | B．1952 | C．1966 | D．1970 |
| A．To tell people that failure is the mother of success. |
| B．To praise scientists’ efforts in making people’s lives easier. |
| C．To describe shop owners’ opinions of barcodes. |
| D．To provide information about the development of barcodes. |
As a young girl, Margaret “Mattie” Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a “shuttle,” a device that carries thread back and forth across a textile loom（纺布机）, fly off the machine when the thread broke, striking and killing a young boy about her own age.
The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn’t bother to patent the device, so she never received payment.
Knight wouldn’t make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued（起诉）, Annan’s argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines.
But that wasn’t the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century.
【小题1】We can learn from Paragraph 1 that ________.
| A．Knight behaved like boys | B．Knight had an unhappy childhood |
| C．Knight did a poor job of making toys | D．Knight liked inventing things as a child |
| A．It is still used today. | B．It brought her great profit. |
| C．It was made when he was 20. | D．It reduced injuries at textile plants. |
| A．stole the wooden model for the machine she invented. |
| B．failed to make the full-sized machine for her |
| C．tried to patent her invention for himself |
| D．kept the metal version for himself |
| A．Mattie Knight’s fight for her patent | B．A great woman in the 19th century |
| C．“The female Edison”, Mattie Knight | D．Great inventions, great woman |
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
For over one hundred and fifty years,Americans of all social classes have worn blue jeans.【小题1】 Whether they are worn for work or for fashion today.Strauss’ invention continues to be popular not only among Americans but also among people around the world.
Levi Strauss was born in Germany in 1829.【小题2】 He grew up in Kentucky before moving to New York in 1847.?Before becoming an American citizen and moving to the West in 1853,Strauss worked in his brother’s dry goods business.This gave him a chance to produce his famous invention. After the gold rush of 1949,Strauss decided to move to the West to seek his fortunes.
Strauss did not want to be a person who searched an area for minerals.Instead,he knew he could make a good living by selling supplies to the miners.At first,he planned to sell sewing supplies and cloth.【小题3】 When he heard miners complaining that their clothes were easily broken or they usually tore their pockets during mining,he decided to use a special fabric to make pants for the miners.These pants proved so popular that he quickly ran out of materials to make more.
In 1873,Strauss received a letter from a Jewish tailor named Jacob Davis who had invented a process of connecting pockets with copper rivets(铆钉).This made the pants last a long time.Because Davis did not have the money to patent his idea,he offered to share it with Strauss if Strauss would agree to pay for the patent. 【小题4】 .
By the time Strauss died in 1902,he had made a great contribution to American fashion.
【小题5】 The business has been growing ever since and Levi Strauss’ company is now one of the largest clothing companies in the world.
| A．As a young boy,he moved with his family to the United States. |
| B．Nobody knew what kind of material was suitable. |
| C．He did and Levi jeans have been made with metal rivets ever since. |
| D．However,he did not get much business for those products. |
F.Since they were invented by Levi Strauss,they have ?become? a symbol of American consumer culture.
G.As the business grew,Strauss got much money from it.
