What does the speaker say about the skin of starfish? [br]
Welcome to our aquarium. As we begin our tour, the first animal we will see today is the starfish. You probably have seen pictures of the starfish, but in a few minutes you will see some live ones and learn a little about their structure. First of all, starfish are not really fish, they belong to the family of echinoderms which are spiny skinned sea animals, (17)that is, their skin is covered with thorny bumps. Most starfish have five arm-like extensions on their bodies. And so they look like a five-pointed star. But some other kinds have as many as 40 or more arms. Starfish, like other members of the echinoderm family, have what’s called radial symmetry.(18)All that means is that the body part of these animals are arranged around the center, kind of like spokes of a wheel around a hub. One of the special features of the starfish is that(19)it can drop off arms as a defensive reaction, to get away from an attacker, for example. They can then grow new arms to replace the old ones.
选项
A、To explain how the starfish reproduces.
B、To illustrate the shape of the starfish.
C、To demonstrate the defense mechanisms of starfish.
D、To show how starfish moving.
答案
B
解析
语义理解题。根据句(18)可知,讲到海星形状的时候,导游举的例子是用来说明海星形状的。因此B为正确答案。
