最近在嘉兴二模的阅读理解C篇中看到这个词组，觉得值得学习一下。
C
The Malagasy baobab trees, a typical feature of' Madagascar's landscape, should have disappeared long ago due to the extinction of its former seed-distributing animals. However, it did not. Seheno Andriantsaralaza at the University of Antananarivo in Madagascar and Onja Razafindratsima at the University of California, Berkeley, now think they may know the reason.
Together with their colleagues, the scientists monitored 15 trees to find new baobab seed-di stributing animals in a western Madagascar region. They also set up camera traps around seed-containing fruits, and searched any faces(粪便) along the way for the presence of seeds.
They report in the journal Biotropica that a native rat was caught on camera handling whole fruits on four occasions. Although there was no record of the rat breaking the fruits open, the team found 13 fruits that had been chewed into and had their seeds removed. Though the bite marks were not clear enough to identify a culprit(肇事者), this was clear evidence that a seed-distributing animal was out there. They then found convincing evidence：baobab seeds in seven different piles of bush-pig faces.
The discovery is not without irony(讽刺). Scientists believe bush pigs were brought to Madagascar by humans sometime between 1,000 and 5,000 years ago, just as the former seed-distributing animals were going extinct.Their arrival was a lucky break for the baobabs, especially as scientists have determined a seed's journey through the pig-like digestive system doesn't reduce its ability to grow.
While the finding is important in its own right, it also provides valuable evidence that introduced species may not be entirely harmful. Madagascar's pigs, for example, though not native, have made themselves essential to the survival of truly native species. Similar relationships are suspected to hold in South America between rabbits native to Europe and plants with no seed distributors. For Dr. Andriantsaralaza, that suggests the full ecological role of introduced species should be considered before talk of extinction begins.
