20、t. Part 2 Passage Mexican Gray Wolf Exercise A Pre-listening Question The 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 par

21、ent, a female parent, their pups and a few other adult wolves who are the 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 s

22、everal winter months of perpetual darkness. Even in February when the sun returns to the north, temperatures of -40°C 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.

23、 1) 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. 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

24、square kilometers. 3) Decisions about mating, movement among the 45 captive-breeding facilities 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·

25、 of the high mortality rate in the wild. 5) The recovery program is gradually moving away from freeing 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.
