400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(蘚類植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(莖). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔蘚類植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(瀕絕生物保護(hù)區(qū)), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings(論文集)of the National Academy of Sciences.
1.Dr La Farge’s research is of great importance to ________.
A. knowing what the plants during the Little Ice Age were like
B. understanding how ecosystems recover from glaciers.
C. regrowing many species that have been destroyed before.
D. figuring out the effects of melting ice caps on moss.
2.The underlined part “blew my mind” in Paragraph 6 can best be replaced by “________”.
A. surprised me B. greatly frightened me
C. put my doubt out of my mind D. was exactly what I had in my mind
3.According to the passage, Aulacomnium turgidum ________.
A. lives better in small groups
B. is very active in hot weather
C. is strong enough to survive coldness
D. is chosen from Canadian refugia
4.Which of the following would be the best title for the passage?
A. Bryophyte ecology is greatly affected by climate change.
B. 400-year-old moss’s survival is a mystery to solve.
C. Moss in ancient times was discovered in Canada.
D. 400-year-old plants were brought back to life.

When I was born, my parents immediately noticed something wrong. My feet were deformed (畸形的), pointing inward and curling under. I wore casts (石膏) and foot braces (支架) in my first two years to correct the problem. Yet I learned to balance and walk in casts. Soon after the last set of casts came off,Mom enrolled me in dance classes as therapy for my feet. I, however,quickly decided to try something else. Not far from my house was an ice rink (溜冰場(chǎng)) in the mall. There,local skaters would perform ice shows. I wanted to try skating.
I started taking group skating lessons. Performing on ice came naturally. For me,skating has never been about beating others. It’s been about being my personal best. I progressed through various levels rapidly and gave my first ice performance at age seven. Soon I started winning local and regional competitions. That’s because being on the ice has always been the one place I can truly express my emotions. The ice is like home.
I began seriously training when I was nine years old. After graduating from girls’ high school,I moved to Canada. Saying goodbye to my family and friends made me homesick,but I knew deep down that I had to leave and train full-time to give my dreams a chance at reality.
I went to compete in the Olympic Games in 1992.I was the first of the final six skaters on the ice. My long performance started well,but I slipped while landing one of my easiest triple jumps,and my hand touched the ice. I didn’t want to make two mistakes in a row,so next I did a jump with just two spins to play it safe. As I neared the end,I had one more jump. I landed it perfectly.
When medals were awarded,I found myself on the top step,the gold hanging around my neck and America’s national anthem playing. Words can’t describe the overwhelming mixture of emotions I felt.
