活力课时同步练习册系列答案There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century．
In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India．In order to reduce fraud（诈骗）, he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay．This finding inspired him to begin investigating fingerprints．In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system．Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist (优生学家). Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system—the first existence．
Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system．In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, they matched Rojas' exactly．She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy（指纹鉴定法）. It's still used in many Spanish-speaking countries．
Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world．

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.
【小题1】What does the passage mainly talk about?
| A． Pollution caused by plant construction. |
| B． Effects of windmills on the environment. |
| C． Economic growth and human civilization. |
| D． Economic growth and environmental damage. |
| A．Goods and products | B．The industrial plants |
| C．Water and atmosphere | D．Negative health effects |
| A． economic growth should be calculated in terms of GDP |
| B． use of natural resources causes no damage to the environment |
| C． industrial manufacturing may cause damage to the environment |
| D． a windmill is a perfect way to produce economically practical energy |
A Japanese toy maker declares that they have developed a gadget that translates dog barks into human language and plans to begin selling the gadget——under the name of Bowlingual——in U. S. pet stores and gift shops this summer.
Tokyo-based Takara Co. Ltd. says about 300, 000 of the dog translator gadgets have been sold since it was on sale in Japan late last year. It is forecasting far bigger sales once an English language translation for dogs comes to America in August. The United States is home to about 67 million dogs, more than six times the number in Japan.
"We know that the Americans love their dogs so much, so we don't think they will mind spending $ 120 on this product, " the Takara marketing manager said during an interview at a recent pet products conference in Atlanta.
Regarded as one of the coolest inventions of 2002 by Time magazine, Bowlingual is made up of a 3 - inch long wireless microphone that is fastened to a dog collar and sends out sounds to a small console (控制台) that is connected to a database (数据库). The console divides each bark into six emotional types——happiness, sadness, disappointment, anger, threat and desire——and shows common phrases, such as "You're ticking me off," that fit the dog's emotional state.
Takara says it has spent millions of dollars developing the gadget in cooperation（合作）with famous sound experts and animal behaviorists.
One thing that does appear certain is that the markets for animal translation products will likely remain a dog's world since Takara has no plans to develop a similar gadget for cats. "They are too unpredictable (反复无常) , " the marketing manager said.
【小题1】This passage mainly tells us that Bowlingual ___________.
| A．was invented in Japan | B．has developed quickly |
| C．will be sold in America | D．sells well for its price |
| A．markets | B．products | C．plans | D．cats |
| A．proud of | B．satisfied with | C．confident of | D．worried about |
