5. The lionfish is a tropical species native to the Indian and Pacific oceans. Noted for its vibrant colors, the lionfish was once a prized aquarium fish, especially in North America. However, its voracious appetite led to it attacking other fish kept in the same aquariums and resulted in many owners disposing of their lionfish in nearby waterways. While many lionfish died in the wild, they have found homes in the Caribbean Sea and Western Atlantic Ocean, where their numbers are exploding. They are consuming large numbers of fish in coral reefs and being general nuisances, so people are devising ways to get rid of them.
Few fish actively hunt the lionfish, but the grouper is one. Yet the grouper is a popular food fish around the world, so fishermen commonly catch it. Some people have proposed enacting quotas on the number of groupers caught in areas with numerous lionfish. By doing so, the grouper population can increase, and then there will be more groupers to hunt lionfish.
Fishermen are now being encouraged not to release any lionfish they catch but to kill them even if they have no plans to eat them. Divers with spear guns are similarly being asked to shoot any lionfish they find, especially those living in coral reefs. While the fishermen and divers may not kill large numbers of lionfish, they can actively reduce their numbers.
People living in tropical areas are promoting the consumption of lionfish. The fish, which taste delicious, are considered a delicacy in China. By educating people in the United States and other countries about how good lionfish tastes, demand for the fish should increase, so more fishermen will start catching them. This should result in there being fewer lionfish in some regions.

-increase demand for lionfish=more fishermen catch them
Sample Note-LISTENING
can't control lionfish population
1 problem w/using groupers
-lionfish eat juvenile groupers→eat them before grow bigger
-many in Caribbean make living catching grouper so don't want it protected
2 lionfish is dangerous
-has spines with venom→can be fatal to humans
-have to be careful around lionfish
3 many don't want to eat lionfish
-spines and venom scare people
-must prepare fish properly or can be poisoned
Sample Essay
The focus of the lecture and the reading passage is the lionfish, a nuisance fish which is increasing in number in the Caribbean Sea and parts of the Atlantic Ocean. Whereas the writer of the reading passage believes the lionfish population can be controlled, the professor has her doubts.
She starts by talking about efforts to increase the grouper population since groupers hunt and kill lionfish. The writer of the reading passage remarks that establishing quotas on grouper fishing will increase the grouper population, but the professor notes that lionfish hunt juvenile groupers, which are unable to hunt lionfish. She also says that many Caribbean fishermen catch groupers, so she does not believe the grouper population will increase much.
While the writer of the reading passage declares that fishermen and divers can be convinced to catch and kill lionfish, the professor is skeptical of this claim. She says the spines of lionfish have dangerous venom, so catching lionfish is something few people want to do.
The last argument concerns people eating lionfish. The professor says that people will not eat much lionfish since preparing it is hard and few people want to eat something potentially fatal. Those two points counter the argument in the reading passage that spreading the word about the delicious taste of lionfish will convince more people to eat it.

【答案解析】 [听力原文]
Now listen to part of a lecture on the topic you just read about.
W Professor: In the late 1990s, the lionfish population in the Atlantic Ocean and Caribbean Sea began increasing. Today, the fish is a serious problem as it consumes numerous commercial species of fish and is endangering many coral reefs as well. Of course, people are coming up with ways to solve the lionfish problem, but, if you ask me, the lionfish population is simply too large and widespread to be controlled.
Some people are hoping to increase the grouper population by protecting the fish since groupers hunt lionfish. However, lionfish have an effective tactic against groupers. They, uh, they eat juvenile groupers. Basically, um, lionfish kill groupers before the fish become big enough to hunt them. In doing so, lionfish are ensuring their own survival. Oh, and many people in the Caribbean don't want to protect the grouper since they make their living catching it.
I've heard that both fishermen and divers are being encouraged to catch and kill lionfish. Well, look at this picture before you decide to hunt them...Notice the protruding spines on the lionfish. Nasty, huh? Those spines, by the way, produce a venom that's painful to humans and is sometimes even fatal. So you need to be careful around lionfish if you're trying to catch them, and that makes most people just avoid them in general.
Some people are promoting the eating of lionfish. Sure, they taste great, but those spines and venom are two reasons lionfish isn't on many restaurant menus. For one, preparing the fish requires special skills to prevent accidental poisoning. Next, many people are afraid of eating animals with poison in their bodies no matter how well the meat is prepared and cooked. So I doubt that lionfish is going to become popular in most places.
