问题 With what topic is the passage mainly concerned?
The hydra is a kind of______.

选项 A、flatworm
B、coelenterate
C、sea anemone
D、nerve cell

答案B

解析学生肯定不知道hydra和coelenterate这两个词意思。没关系，看看上下文就知道了：Nerve cells evidently first appeared in coelenterates——“hollow-gutted” organisms like hydra and the sea anemone．这里通过organisms就把这两个词连起来：coelenterates就是“hollow—gutted” organisms，而通过like这个词来举例，hydra是"hollow-gutted organisms”即coelenterates的一种。
