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 light-s

6、ensitive 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. But

Part 2 Passage Mexican Gray Wolf Exercise A Pre-listening Question The wolf

20、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 older

21、 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 retur

22、ns 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 dwindled

23、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 facilities a

24、nd 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 freeing

25、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 gray wo

26、lf 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-renowned natu

27、ralist 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 or taken

28、 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 wild pop

29、ulation 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 them off to

30、 live on their own. Nine of Francisco and Sheilas offspring were among the first 11 captive-born Mexican gray wolves released in 1998.
