Text Study Unit Summary : 1) Human prevention 2) Technical prevention 3) Elimination of stolen property receivers

Part 1 Warming up The following questions refer only to things that happened to You or Your Partner during the last six years . • Did you have your (picked/purse snatched ) ? • Did anyone take something (else) directly from you by using force ,such as a stickup , mugging or threat ? • What kind of crimes mostly disturb you and your family members ?

Part 2: Reading Comprehension • Fingerprint technology has developed more in its east 15 years than it did in the first 100 years. Advancements in technology have led to new capabilities allowing investigators to pull prints from surfaces that used to be very difficult or even impossible. • The key points to any of the following systems include accuracy, reliability, ease of use, open system design (compatibility to various computer platforms), easy serviceability and expandability. • There are several innovative products IBIS, TENPRINTER, FingerPrinter CMS, FaceIt and BNP that will shape future investigation and crime prevention methodology．

The product with the greatest potential to impact officers in the short-term is IBIS，a revolutionary mobile identification system that captures forensic quality fingerprints and Photographs. TENPRINTER and FingerPrinter CMS are live scan systems，which capture fingerprint images without the use of ink. Law enforcement，government agencies，airport，banks and other commercial institutions are increasingly using these systems． • FaceIt is a widely deployed facial recognition software that allows computers to rapidly and accurately detect and recognize faces. Its uses include ID verification，surveillance，information security and banking. BNP incorporates FaceIt technology for implementation over large-scale network and real-time identification.

IBIS is a handheld portable device known as. a remote data terminal（RDT），which captures data（including photographs），forensic-quality fingerprint images and magnetic stripe data．The data is transmitted wirelessly to a laptop in a squad car and to the central IBIS server via the police radio communication system or cellular communications．At the IBIS server，the data is processed • and transferred to one or more AFIS databases．If a fingerprint match exists，identification information -is transferred back to the RDT．If there is no match，the fingerprint and photo files are discarded from the system． • Fingerprint scanning capability while officers are on patrol is highly desirable，but dependable technology is just coming around．

A report released by a group of experts after the first week of operation indicated IBIS was used 173 times in test and operational scenarios，returning 71 matches，including four individuals who gave false information to officers，against the Automated Fingerprint Identification System（AFIS）．The, experts confirmed the information returned by IBIS and identified outstanding warrants against the individuals．Additionally，IBIS successfully identified a body found in an apparent suicide of an individual who had a prior criminal record． • The future application of these technologies will keep law enforcement current in a technology-driven .world that is rapidly changing on all fronts.

Amazon

The Amazon Rainforest is the world’s greatest natural resource—the most powerful and bio-actively diverse natural phenomenon on the planet. Yet still it is being destroyed just like other rainforests around the world. The problem and the solution to rainforest destruction are both economic. Rainforests are being destroyed worldwide for the profits they yield—mostly harvesting unsustainable resources like timber, for cattle and agriculture, and for subsistence cropping by rainforest inhabitants.

Discussion Questions: • Do you enjoy the beauty of the rain forest where different kinds of animals live in harmony with each other? What can human being do to protect that? • What do you think of the statement “we human being and other species share the same globe”?

3. Work in pairs to discuss what ecology is? Ecology is the study of the relationships among plants, animals, people, and their environment and the balance among these relationships. An ecologist may study the behavior of individuals. Among the characteristics studied would be the food-gathering techniques of individuals, the survival adaptations against predation, etc.

4. Work in pairs to discuss what environment is? Environment is the complex of physical, chemical and biotic factors that act upon an organism or an ecological community and ultimately determine its form and survival.

For Fun Enjoy a Humor A man was driving along the country road. Then he saw right in the middle of a field, there was a farmer standing there still and doing nothing. He stopped his car and got out of it. He approached the farmer and asked “I have seen you standing here for quite a few minutes. What are you doing here?” The farmer answered “I’m trying to win a Nobel Prize.” The man was very curious and asked “How can you win a Nobel Prize by standing here?”Can you guess what the farmer answered?

The farmer answered: “I’ve heard they give the prize to people who are outstanding in their field.”
