1、Unit 4 Section One Tactics for ListeningPart 1 Spot DictationStephen Powelsons Amazing MemoryWhen Stephen Powelson was nine, his school organized a (1) weekly contest in memorizing passages from the Bible. Stephen paid (2) no attention until he was chided* for (3) not competing. The next Sunday he s
2、urprised everyone by (4) reciting all the passages for the (5) entire year. As a teenager in prep school, Stephen took Greek. His teacher (6) assigned 21 lines of the Iliad* to be memorized (7) in a week. At the end of the hour - though he (8) insisted he paid full attention to the (9) lecture - Ste

To keep his mind active, he reread the Iliad and (13) discovered that he still knew the first 100 lines (14) by heart. That someone could mem

Powelsons method is to (18) read a book into his tape recorder, then read it several more times, making sure he understands (19) each word. “Also,“ he says, “I a

The most common way to observe the skies is to photograph them. The process is very simple. First, a photographic plate is coated with a ligh
6、t-sensitive material. The plate is positioned so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged, and published so that many people can study it.Because most astronomical objects are very remote, the light we receive from them is rather feeble. B
7、ut by using a telescope as a camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.1) This passage is about how to photograph astronomical objects.2) Photograph, coated, light-sensitive mate

Agent: Yes, theyre very peaceful and you spend the fifth day there. The fishermen will take everyone ou

Part 2 Passage Mexican Gray Wolf Exercise A Pre-listening Question The
20、wolf is a large member of the canine(犬科的) family. Most of the adult grey wolves weigh in the vicinity of 75 to 125 pounds (34 to 56 kilograms). Wolves live in family groups called packs. A pack is usually made up of a male parent, a female parent, their pups and a few other adult wolves who are the
21、older brothers and sisters. Wolves can run up to 40 miles an hour and can easily cover 50 miles a day. The wolf has developed the capacity to survive in the most inhospitable of climates. The wolves in the high arctic endure several winter months of perpetual darkness. Even in February when the sun
22、returns to the north, temperatures of -40C and bitter winds are common. In the wild wolves can live up to 13 years or more; in a protected wolf park or a controlled area of land, a wolf can live to be up to 16 years old. 1) After more than a century of assault by humans, the wolf population had dwin
23、dled to no more than a handful by the 1970s in Mexico and the American southwest. 2) The program is now about halfway to meeting its goal of a “wild“ population of at least 100 wolves covering more than 12,800 square kilometers. 3) Decisions about mating, movement among the 45 captive-breeding facil
24、ities and releases into the wild are made by a US-Mexican committee of scientists, land owners and others. 4) A wolf with rare genes - until it has successfully reproduced - will never be released because of the high mortality rate in the wild. 5) The recovery program is gradually moving away from f
25、reeing captive-born wolves, as the population of pups born free takes off. *Francisco and Sheila were pioneers in a federal program in Eureka, 32 kilometers southwest of S1. Louis, the United States, to restore the endangered Mexican gray wolf, the rarest and most genetically distinct subspecies of
26、gray wolf in North America. After more than a century of assault by humans, the wolf population had dwindled to no more than a handful by the 1970s in Mexico and the American southwest. The research center, popularly known as the Wolf Sanctuary*, was founded in 1971 by Marlin Perkins, a world-renown
27、ed naturalist and former director of the St. Louis Zoo, and his wife Carol. Besides the Mexican wolf, the sanctuary works with the endangered red wolf, maned wolf (maned: 有鬃毛的; maned wolf 鬣狼 ), swift fox and African wild dogs. In the late 1970s, the last seven known wolves were captured in the wild
28、or taken from zoos to begin the breeding program. In 1981, the first captive-bred litter of Mexican gray wolves produced in the federal program was born at the Wild Canid (犬科动物) Center, and the first release into the wild took place in 1998. The program is now about halfway to meeting its goal of a
29、“wild“ population of at least 100 wolves covering more than 12,800 square kilometers. Though in captivity themselves, Francisco and Sheila taught their pups so well that many are thriving in the wild. They were ideal parents. They raised 25 babies, taught them good survival skills and sent many of t
30、hem off to live on their own. Nine of Francisco and Sheilas offspring were among the first 11 captive-born Mexican gray wolves released in 1998. Both parent wolves have since died - Francisco at age 14 in December. Sheila at age 16 in June 2000 - but they lived, as captive wolves often do, roughly t
31、wice as long as wolves in the wild. Today the Wild Canid Survival and Research Center in Eureka estimates that 98 percent of Mexican wolves released from the federal program are descendants of the prolific* lobo* pair. （lobo=timber wolf）About 250 lobos now live in captivity at 45 US and Mexican faci
32、lities. The Wild Canid Center, however, has produced more puppies and housed more Mexican grays than any other facility.
