Ⅵ.阅读理解

• 22．For many Americans，monarch butterflies（黑脉金斑蝶） are a sign of changing seasons.
     In the late summer and early autumn，the butterflies fly south，from Canada and the United States' mainland to Mexico.
     But Darlene Burgess still keeps seeing the bright，colorful insects and she lives in Canada.
     Burgess keeps a count of monarch butterflies at Point Pelee National Park in Ontario（安大略）. "As nice as this （the large number of monarch butterflies） is to see，I really wish I wouldn't see it because they're running out of time，" she said. "It's really not good for them."
     Monarch butterflies are not just staying in Canada.Groups of them have been seen north of the Mexican border，such as the American state of New Jersey.Their large numbers are not normal for late October.
     Monarch butterflies normally arrive in Mexico around November 1st.The number of "stragglers" in Canada and the US is "definitely new territory for us，" said Chip Taylor，a biology professor at the University of Kansas.He is also the director of Monarch Watch，an organization that studies the butterflies.
     There are a few reasons why the monarch butterflies did not fly south when they should.Some monarch butterflies were born late.Some did not move south because of warm weather.Others could not fly south because of windy weather that lasted for weeks.
     Now，they may be stuck because temperatures are starting to fall.Elizabeth Howard is a biologist and director of a group called Journey North.She said monarch butterflies' muscles（肌肉） do not work well when temperatures go below 15 degrees Celsius.If the butterflies do not freeze，they are likely to starve（挨饿） to death because many of the plants they eat are gone for the season，Howard noted.
     In fact，monarch butterflies have faced a number of problems in recent years. "Losing home，climate change，pollution，and a decreasing food supply are making the number of the butterflies fall，" said Lincoln Brower，a biology professor at Sweet Briar College.Lincoln Brower has been studying the butterflies since 1954. "They need legal（法律的） protection-not just 'on the book'，but in practice，" he added.
