Ⅴ.阅读理解
Imagine if spiderman came down from the ceiling to save Yao Ming or Shaquille O’Neal ever y time they injured their ligaments(韧带)on court.Though this idea will have to remain a daydream，spider silk may really be able to cure their wounds，scientists say.
Though to be the strongest natural fibre on the planet，spider silk could be used to rebuild injured ligaments.Randolph Lewis at the University of Wyoming in Laramie has been working on the
idea.
Spider silk has interested scientists for centuries.An ancient European folk story at least 2,000 years old tells of the possible medical value of spider webs.It said they could help in fighting infections，stopping bleeding and healing wounds.
Researchers have found no evidence so far that spider webs can kill germs.But studies on animals have shown that spider silk helps prevent the rejection of medical implants(移植)．So Lewis’ lab and others’ are changing spider silk into fibres that they hope might be useful in medicine. Researchers have found that spider webs could be used to rebuild ligaments damaged in one of the world’s most common knee injuries.“We’re also looking at spider silk in artificial tendons(腱)，”Lewis said.
Scientists are also developing spider silk to be used for stitching up(缝合)wounds，to help them heal without scarring.
1．The belief that spider silk is useful for rebuilding injured ligaments is based on the idea
that_____________.
A．it has cured Yao Ming and O’Neal’s wounds
B．it’s the strongest natural fibre in the world
C．it has long been used to cure the injured
D．spider silk can be used for stitching up wounds
2．We can learn from the passage that________.
A．it has been proved that spider webs can surely kill germs
B．scientists have long been interested in spider silk because of a folk story
C．2,000 years ago the westerners were sure of the medical value of spider webs
D．much of the medical value of spider silk is being developed by some scientists
3．The passage is most likely to be found in________.
A．a story book B．a scientific journal C．a textbook D．a news report
4．What is the best title for this passage?
A．Unique Medicine B．Wonderful Insects
C．New Findings D．Mysterious Spiderman
