  The Mir Space Station

  The Russian Mir Space Station, which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight, is remembered for its accomplishments in the human space flight history. It can be credited with many firsts in space.

  The Soviet Union launched Mir, which was designed to last from three to five years, on February 20, 1986, and housed 104 astronauts over 12 years and seven months, most of whom were not Russian. In fact, it became the first international space station by playing host to162 people from 11 countries. From 1995 through 1998, seven astronauts from the United States took turns living on Mir for up to six months each2. They were among the 37 Americans who visited the station during nine stopovers by space shuttles.

  The more than 400 million the United States provided Russian for the visits not only kept Mir operating, but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.

  A debate continues over Mir's contributions to science. During its existence, Mir was the laboratory for 23,000 experiments and earned scientific equipment, estimated to be worth $80 million, from many nations.3 Experiments on Mir arc credited with a range of findings, from the first solid measurement of the ration of heavy helium atoms in space to how to grow wheat in space. But for those favoring human space exploration, Mir showed that people could live and work in space long enough for a trip to Mars. The longest single stay in space is the 437.7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995. And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station. The longest American stay was that of Shannon Lucid4, who spent 188 days aboard Mir in 1996.

  Despite the many firsts Mir accomplished, 1997 was a bad year out of 15 for Mir, In 1997, an oxygen generator caught fire. Later, the main computer system broke down, causing the station to drift several times and there were power failures.

  Most of these problems were repaired, with American help and suppliers, but Mir's reputation as a space station was ruined.

  Mir's setbacks arc nothing, though5, when we compare them with its accomplishments. Mir was a tremendous success, which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible. But it's time to move on to the next generation. The International Space Station being built will be better, but it owes a great debt to Mir.

  We can learn from the passage that the Mir Space Station__________

  A.was designed to last over 5 years

  B.played host to 7 astronauts from different countries

  C.was visited only by Americans

  D.was built by Russians

  A.Flying Vertebrate

  1 The fossil remains of the first flying vertebrates,the pterosaurs, have intrigued pale-oncologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspan from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were reptiles or birds—are among the questions scientists have puzzled over.

  2 Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls,pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing like membranE.The othe fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger,and with it the wing,could only turn upward in an extended inverted V shape along each side of the animal's body.

  3 The pterosaurs resembled both birds and bats in their overall structure and proportions. This is not surprising because the design of any flying vertebrate is subject to aero dynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts.

  4 Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T. H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperaturE.Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hair like fossil material was the first clear evidence that his reasoning was correct.

  5 Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs' hind feet resembled a bat's and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.

  It can be inferred from the text that scientist now generally agree that the

  A.enormous wingspan of the pterosaurs enabled them to fly great distances

  B.structure of the skeleton of the pterosaurs suggests a close evolutionary relation-ship to bats

  C.fossil remains of the pterosaurs reveal how they solved the problem of powered flight

  D.pterosaurs were reptiles

  D.target
