Today we are going to talk about a species of fish that is rather unique: Today’s lecture is about sea horses, if you’ve seen a sea horse, you may have noted that it has a horse-like head attached to its body. The sea horse has a long snout that is good for sucking. Instead of scales like most fish, sea horses have skin that is stretched over bony plates. The body extends to a prehensile tail, meaning that the tail can be used to grasp. The sea horse may grasp sea grass or coral to keep it stable in a moving current.
The sea horse has fins on its back that it can use to propel it through the water. However, sea horses aren’t very good swimmers. They do not move quickly over great distances. The sea horse also has chest fins that it uses for stabilization. The chest fins help the sea horse float in an upright position.
One particularly unique feature of sea horse is that only the male becomes pregnant. The female inserts ripe eggs into the male’ pouch, where they are fertilized. The eggs become embedded in the pouch wall.
选项
A、The sea horse has a long snout that is not convenient for sucking.
B、Sea horses have no scales at all.
C、The sea horse is unable to grasp sea grass or coral.
D、Sea horse can move very fast over long distance.
答案
B
解析
该题需要综观全文。如果听出“海马的嘴就是利于吸食”,则容易判断选项a错误。听出“海马尾巴的作用就是抓取物体”,则可以判断选项c错误。听到“海马并不是游泳健将”,可以判断海马移动并不很快,因此选项d错误。选项b正确。
