Fishermen from the Brazilian town of Laguna have developed a unique symbiotic (共生的) relationship with dolphins： they rely on the intelligent creatures to help them catch fish. Studies have shown that there’s a particular group of about 20 bottlenose dolphins that work alongside the fishermen， while the rest of the local dolphins prefer to look for food on their own.
The dolphins work together to drive groups of fish towards the fishermen。

They then use head。

or fin.signals to warn the fishermen about when and where the nets should be thrown。

The system works well for both parties： neither could survive without the other。

The fishermen get to catch all the fish they need, while most of the escaped fish swim right into the dolphins' mouths. The water is so dark near Laguna that the fishermen could never catch fish as efficiently without the dolphins' help. That’s why they only fish when dolphins show up.
“About 200 local fishermen are almost entirely dependent on the dolphins for catching fish，” study researcher Fábio Daura­Jorge said。

“The fishermen do not fish without the assistance of the dolphins and know the individual animals from their natural marks and can recognize them by eye。

”
Interestingly, the researchers discovered three different social networks of
dolphins in Laguna， only one of which cooperate (合作) with the fishermen。

The cooperation might be a learned behavior characteristic，because nothing in the environment actually stops other dolphins from helping the fishermen as well。

Researchers believe that the behavior is passed down from mother dolphins to their babies, through social learning. Similarly, elder fishermen teach their children how to work with the dolphins。

This unique form of cooperative fishing has been going on for at least 120 years，as proven by a 19th.century letter that mentions the special dolphins of Laguna， but no one knows exactly how it started.
语篇解读：本文为说明文，题材为自然地理类。

本文介绍了一个巴西小镇的渔民和海豚互相协作，共同捕鱼的共生现象。

A．They get most of the fish。

B．They get escaped fish only.
C．They are protected by the fishermen。

D．They get fish thrown by the fishermen。

解析:选B 细节理解题。

由第二段“。

.while most of the escaped fish swim right into the dolphins' mouths"可知，海豚把鱼群赶入渔民的网中，逃脱的鱼就进了海豚的嘴里。

6．Why do the fishermen have to fish with the dolphins' help?
A．They are too lazy to fish.
B．The fish are in dark water。

C．They have poor fishing skills.
D．There are not enough fish for them.
解析：选B 细节理解题。

由第二段“The water is so dark near Laguna that the fishermen could never catch fish as efficiently without the dolphins’ help.”可知,因为鱼生活的水域很阴暗，渔民很难判定它们的行踪,因此只能依靠海豚给出的信号来捕鱼.
7．How do the dolphins get the behavior of fishing with the fishermen？
A．They are born with the ability.
B．They are trained by the fishermen.
C．Babies learn it from their mothers.
D．They learn it from other groups of dolphins。

解析:选 C 细节理解题。

由倒数第二段“Researchers believe that the behavior is passed down from mother dolphins to their babies，through social learning.”可知，在这种协作捕鱼的共生关系中，海豚母亲把这种技能教授给小海豚。

8．The text is written mainly to tell us ________。

A．the intelligence of bottlenose dolphins
B．fishing in the Brazilian town of Laguna
C．the life of fishermen in a Brazilian town
D．a symbiotic relationship between humans and animals
