GOODBYE PARTY FOR JOHN -REAL EXAM LISTENING TEST HD

I mean, I don't want to start something and then have to abandon it if they just can't cope. I guess we could end up doing most of the work for them. You're right, well maybe we can save that idea for later. Yes, let's hope this second book has something better. That's the end of section three. Now you have half a minute to check your answers. Now move on to section four, section four. First you will hear a speaker talk about shark mesh in Australia. First you have some time to look at questions 31 to 40. Now he listens carefully and answers questions 31 to 40.

Today we will look at one of my favorite fish, the shark. As you know, sharks are reputed to be very dangerous creatures capable of injuring or killing humans and I would like to talk about sharks in Australia. Sharks are quite large fish that often grow to over 10 meters and the longest sharks caught in Australia reach 16 meters. Sharks vary in weight depending on size and breed of course, but the heaviest shark caught in Australia It was a white pointer that weighed 795 kilograms. Sharks of fairly large size have a different structure than most fish instead of a skeleton made of bone.

They have a skeleton of elastic and resistant cartilage. Unlike bone, this firm, flexible material is more like your nose and allows the shark to bend easily while swimming. The shark's skin is not covered with scales like other fish, but the skin is covered with spikes that give it a rough texture like sandpaper, as you know, sharks are very fast swimmers, this is possible. by its fins, one placed on the side and one under the body, and the tail also helps the shark to move forward quickly, unlike other fish, sharks have to keep swimming if they want to stay at a particular depth and they rarely swim in the surface, mainly Swimming at the bottom of the ocean, scavenging through trash, and picking up food found on the ocean floor, while most other animals, including fish, hunt their prey by sight.

Sharks hunt essentially by smell. They have a very keen sense of smell and can sense presence. of food long before they can be seen in Australia, where people spend a lot of time on the beach, the government has

real

ized that they must prevent sharks from swimming near their beaches, as a result they have introduced a netting program beach. Placing large nets parallel to the coast means that nets on New South Wales beaches are set one day and then lifted and carried out to sea the next day. When shark netting began in 1939, only metropolitan Sydney beaches were netted.

These beaches were chosen because the beaches close to the city tend to be the most popular for swimmers. Ten years later, in 1949, the systematic grid was expanded to include beaches south of Sydney as a result of the overall success of the program in Sydney. Shark netting was introduced in the State of Queensland around 1970. New Zealand authorities also looked at it, but deemed the net uneconomical, as did Tahiti in the Pacific, around the same time South Africa introduced netting. on some of its most popular swimming beaches. When the mesh began, approximately 1,500 sharks were caught in the first year, however this decreased in subsequent years and since then the average annual catch has been only around 150 per year.

Most sharks are caught during the warmer months, November to February, when sharks are most active and when both the air and ocean are at their highest temperatures. Despite fairly large catches some people believe that nets Meshing is not the best way to catch sharks. It's not that I think sharks are afraid of nets or because they eat holes in them because none of this is true, but meshing seems to be less effective than other methods, especially when there are large C with high waves and strong currents and anything that allows the sand to move, the sand holding the nets down when it moves, the nets will also become less effective.

At the end of section four, you now have half a minute to check your answers. That's the end of the
