On May 23,1989，Stefania Follini came out from a cave at Carlsbad，New Mexico.She hadn't seen the sun for eighteen and a half weeks.Stefania was in a research program，and the scientists in the program were studying body rhythms(节奏)．In this experiment Stefania had spent 130 days in a cave,30 feet in depth.

During her time in the cave，Stefania had been completely alone except for two white mice.Her living place had been very comfortable，but there had been nothing to tell her the time.She'd had no clocks or watches，no television or radio.There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting.Stefania had been in the cave for over four months，but she thought she had been there for only two.Her body clock had changed.She hadn't kept to a 24­hour day，she had stayed awake for 20～25 hours and then had slept for 10 hours.She had eaten fewer meals and had lost 171 bs in weight as a result！She had also become rather depressed(抑郁)．

How had she spent her time in the cave？As part of the experiment she'd done some physical and mental tests.She'd recorded her daily activities and the results of the tests on a computer.This computer had been specially programmed for the project.Whenever she was free，she'd played cards，read books and listened to music.She'd also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature.For example，the pattern of day and night makes us wake up and go to sleep.However，people are affected in different ways.Some people wake up naturally at 5：00 am，but others don't start to wake up till 9：00 or 10：00 am.This affects the whole daily rhythm.As a result，the early risers are at their best in the late morning.The late risers, on the other hand，are tired during the day and only come to life in the afternoon or evening!

68．Stefania stayed in the cave for a long time because________.

A．she was asked to do research on mice

B．she wanted to experience loneliness

C．she was the subject of a study

D．she needed to record her life

69．What is a cause for the change of Stefania's body clock?

A．Eating fewer meals.

B．Having more hours of sleep.

C．Lacking physical exercise.

D．Getting no natural light.

70．Where does the text probably come from ?

A．A novel.         B．A news story.

C．A pet magazine.      D．A travel guide.

       [1] Rising temperatures have forced many plants to climb to higher elevations（海拔）to survive, researchers reported．

       [2] More than two-thirds of the plants studied along six West European mountain ranges climbed an average of 29 meters in altitude in each decade since 1905 to better conditions on higher ground, the researchers reported in the journal Science．

       [3] “This is the first time it's shown that climate change has a significant effect on a large set of forest plant species,” said Jonathan Lenoir, a forest ecologist at Agro Paris Tech in France, who led the study．“It helps us to develop our understanding of how ecosystems respond to temperature changes．”

       [4] The French team's findings suggest plants at high altitudes face the same or greater impacts from rising temperatures．“Plants species move where it's the most suitable for them to grow,” Lenoir said．“If you change these good conditions, species will move to recover the same conditions．”

       [5] Using database on plant species found at specific locations and elevations stretching back to 1905, the researchers showed many plants have steadily climbed higher to conditions best suited for survival and growth．

       [6] Plants move higher when they disperse （分散） their seeds in the wind, which blows them to high elevations and cooler temperatures similar to their former location, Lenoir said．

       [7] The researchers tracked 171 forest plant species during two periods-between 1905 and 1985, and from1986 to 2005--along the entire elevation ranging from sea level to 2,600 meters．They found that two-thirds of the plants responded to warming temperatures over that time by________________________________．

       [8] Plants at higher altitudes also appear most sensitive to warmer conditions because slight temperature changes at higher altitudes have a bigger impact．
