We are used to the idea of
aging
in ourselves. We are so used to this that it comes as a surprise to find that there may be some animals that do not age.
Sea anemones (海葵) are an example. Some have been kept for nearly a century without showing any signs of lifelessness. Some kinds of sea worms can even " grow backwards. " If kept in the dark and given nothing to eat, they get steadily smaller. They finally end as a ball of cells looking rather like the egg from which they came. Under good conditions the ball will turn back to a worm and start growing again. One could probably keep them growing and un-growing again and again. [br] This passage is mainly about_______.
选项
A、sea animals
B、cells
C、aging
D、anemones
答案
C
解析
文章讲到了人和海葵的衰老问题。选项D不全面。因此选C。
