For 19 years, the owl researcher, Denver Holt, has journeyed to Barrow, Alaska, each summer to map out the relationship between lemmings (旅鼠) that crawl across the tundra (冻原) and snowy owls that hunt them from above.

As he prepares for his 20th field season in the Arctic, he says that the snowy owl has a role to play in understanding ecological changes in one of the fastest changing places in the world."When lemmings are doing well, everything is doing well," Mr.Holt said."If climate change results in habitat (栖息地) changes and it affects the lemmings, it will show up in the snowy owls because 90 percent of their diet is lemmings.The owls are the key to everything else."

Twenty years of data provides an unusually deep look at the animal's population trends.And more research on snowy owls in other parts of the world ?they are found throughout the Arctic could flag changes in the global arctic ecosystem without the need for any other markers.

"It's a believable point," ..said John W.Fitzpatrick, director of the Cornell Lab of Qrthinology at Cornell University."Systems are difficult, and if we have an easily accessible marker for the system beneath it, that's a really good thing, because we can measure cheaply and easily how an ecosystem is doing.It gives us a quick understanding of the situation."

There is an unscientific reason to study the snowy owl as well, Mr.Holt says.There is something interesting about owls."People pay attention to owls more than other birds because they look like us," he said.'They have a symmetrical (对称的)face, eyes facing forward, a round, flat face and a round head with feathers that look like hair."

63.From the passage, we know that lemmings ____.

    A.live mostly on snowy owls         B.often change their habitat

    C.are increasing rapidly these days       D.can affect the life of snowy owls

64.Which of the following is TRUE according to the passage?

    A.Mr.Holt goes to the Arctic to study snowy owls every winter.

    B.Climate change has a direct influence on snowy owls.

    C.John W.Fitzpatrick thought Mr.Holt's research and findings were useful and meaningful.

    D.People study snowy owls just for scientific research.

65.The underlined word "flag" in the passage is closest in meaning to "____".

    A.influence     B.mark           C.measure        D.cause

66.What is the best title for this passage?

A.Mr.Holt's Research on Ecological Changes            

B.Changes in Snowy Owls

C.Snowy Owls And Eco-changes

  “Well, Harry, ” his mother answered, “perhaps you aren’t very nice to them.If a few people don’t like a person, he or she may not be responsible for that;but if a lot of people don’t, there is usually something wrong, and that person really needs to change.”

  “I’m too old to change, ”Harry said.“I don’t want to go to school.”

  “Don’t be silly, Harry, ”his mother said, going to the garage to get the car out.“You have to go.You’re quite well, and you still have a lot of things to learn.And besides that, you’re the headmaster of the school.”
