There was once a tree in South Africa so wide that it could fit 60 people inside its hollow trunk. The tree reached 62 feet into the sky. It was more than 1, 100 years old. But recently, that tree and others like it have died. Scientists are wondering why.
The tree was a baobab. A baobab looks like a giant oak(橡树) turned upside down. It’s branches resemble roots reaching toward the sky. It grows in Africa and is called the Tree of Life. Baobab trees tend to live a long time. One of the oldest stood for more than 2,400 years. Various baobabs have been used as a shop, a prison, a house, and a bus shelter.
In 2005, scientists began a survey to determine the age of more than 60 baobabs. During the process, they noticed that several of the trees had died. Their results, recently published in Nature Plants, show that nine of the 13 oldest baobab trees and five out of six of the largest died in the 12-year study period.
Stephan Woodborne conducted the baobab study with six other scientists. They say more research is needed to know why the trees died, but they think climate change may be to blame. That’s because the trees showed no evidence of disease. Plus, many were in national parks, so they would have been protected from human harm. Also, Woodborne says, the most affected baobabs are on the outer edge of their ideal habitat(栖息地). Increasing heat and shifting rainy seasons have made it harder for baobabs in these areas to thrive.
Smaller and younger baobabs are dying too. "The big ones and the old ones caught attention of the media," Woodborne says, "But it’s not just those. It’s unprecedented (空前的) that they should be dying across the age
spectrum
. We’ve got to do a reality check on our own footprints in terms of the way we live our lives. If we all changed what we did a little bit, it would start to make a difference."
According to the passage, which of the following statements is NOT TRUE?
选项
A、Further research is needed to know why the Baobabs died.
B、Baobab trees can live a long time.
C、The researchers found that only old baobab trees died.
D、The baobab study involved more than 60 baobabs.
答案
C
解析
细节题。根据文章第四段第二句“They say more research is needed to know why the trees died”可知,科学家们认为需要做更多的研究来了解这些树木死亡的原因,A项正确。根据文章第二段第五句“Baobab trees tend to live a long time”可知,猴面包树的寿命往往很长,B项正确。根据文章第三段第一句“In 2005, scientists began a survey to determine the age of more than 60 baobabs”可知,在2005年,科学家们对60多棵猴面包树展开调查,D项正确。根据文章最后一段第一句“Smaller and younger baobabs are dying too”可知,不是只有老的大的猴面包树才死亡,小的年轻的猴面包树也会死亡,C项错误,故选C。
