30、 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. Thats a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called “Noahs Ark.“ Dr. Duane Kraemer, a professor in Texas A&Ms Colleg

31、e of Veterinary Medicine and a pioneer in embryo(胚胎 ) transfer work and related procedures, says he salutes the Chinese effort and “I wish them all the best success possible. Its a worthwhile project, certainly not an easy one, and its very much like what were attempting here at Texas A&M-to save an

32、imals from extinction.“ Noahs Ark is aimed at collecting eggs, embryos, semen (精子 ) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should be come extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future.

33、It is estimated that as many as 2,000 species of mammals, birds and reptiles w ill become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead f

34、emale panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. “The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a

35、major problem,“ Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and its difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, “add

36、s Kraemer, who is one of the leaders of the Missy plicity Project at Texas A&M, the first ever attempt at cloning a dog. 46 The aim of “Noahs Ark“ project is to _. （ A） implant embryo into a host animal （ B） salute the Chinese efforts in saving pandas （ C） save endangered animals from extinction （ D

37、） introduce cells from a dead female panda into the egg cells of a Japanese white rabbit 47 How long will the Chinese panda cloning project take according to the passage? （ A） 1 Year. （ B） 3 to 5 years. （ C） 2 years. （ D） 25 years. 48 The word “groundbreaking“ (Paragraph 7) can be interpreted as _.

38、（ A） essentially new （ B） pioneering （ C） evolutionary （ D） epoch-making 49 What could be the major problem in cloning pandas according to Professor Kraemer? （ A） Lack of available panda eggs. （ B） Lack of host animals. （ C） Lack of qualified researchers. （ D） Lack of funds. 50 The best title for th

39、e passage may be _. （ A） China-the Native Place of Pandas Forever （ B） Chinas Efforts to Clone Pandas （ C） Chinas First Cloned Panda （ D） Exploring the Possibility to Clone Pandas 51 Centuries ago, man discovered that removing moisture from food helps to preserve it, and that the easiest way to do t

40、his is to expose the food to sun and wind. All foods contain water-cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80% , lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bact

41、eria(细菌 ) which cause food to go bad is checked. Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水 ) is to put food in chambers through which hoi air is blown at temperatures of about 110C at entry to about 43C at exit. This is the usual method for drying suc

42、h things as vegetables, minced meat, and fish. Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the

43、 roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored

44、in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. 51 The chief point of the second paragraph is about _. （ A） the comparison of

45、 lean meat and fish （ B） the removal of water in food （ C） the water content in food （ D） the relationship between water and food 52 It can be inferred from the passage that _. （ A） the fattier fish contain as much water as the lean ones （ B） the fattier the fish is, the more water it may contain （

46、C） a fatty fish holds less water than a lean one （ D） the water content of fish has nothing to do with the content of their fat 53 The word “conventional“ in Paragraph 3 can most probably be replaced by _. （ A） creative （ B） scientific （ C） usual and acceptable （ D） not common 54 Which of the follow

47、ing statements is NOT true about drying food? （ A） the removal of water in food helps prevent it from going rotten. （ B） The open-air method of drying food has been known for hundreds of years. （ C） In the course of dehydration, the temperature of hot current coming from entry to exit is gradually g

48、oing up. （ D） The process of drying liquids is much more complex than that of drying solid food. 55 The last paragraph tends to discuss _. （ A） the reason why housewives like dried food （ B） the general convenience of dried food （ C） the methods of storing food （ D） the advantages of dried, canned a

49、nd frozen food 56 Astronaut Jim Voss has enjoyed many memorable moments in his career, including three spaceflights and one space walk.
