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。
