2. Activities on River Cam Like many rivers, the Cam is extensively used for several forms of recreational activity. These include angling, swimming and various kinds of boating. Angling The water is not murky and is clean enough from its source to its confluence with the Great Ouse to support fish. The fishing rights on the west bank are leased annually to the Cambridge Fish Preservation and Angling Society. The Cam below Bottisham Sluice may still hold burbot, a fish thought to be extinct in English waters since the early 1970s. The last known burbot caught in Britain was in 1969, on the Cam, and in 2010 a fisherman reported spotting two in the Great Ouse. Above Hinxton and Great Chesterford the river holds a stock of wild brown trout, though it is also stocked by the Audley Fly Fishers club and other angling societies who own the rights. Boating All boats require a navigation license from either the Conservators of the River Cam or the Environment Agency. There are public moorings just below Jesus Lock on both sides of the river and on the western bank just north of the bridge at Clayhithe (both with a maximum stay of 48 hours), and unofficial moorings on the railings adjoining Riverside in Cambridge (unlimited stay, but usually fully occupied) which are under review by Cambridge City Council and likely to be reduced to eight or nine formalized residential moorings, or removed altogether. The moorings on the commons in Cambridge (Jesus Green, Midsummer Common map 5 and Stourbridge Common) are reserved by the City Council for holders of its long-term mooring permits. There are also some privately owned moorings. There is a public slipway next to the garden of the Green Dragon pub in Water Street, Chesterton.map 4 This is occasionally used for launching small boats. Swimming The local swimming club's annual swim from the Mill pond to Jesus Green was cancelled for some years in the past because of higher pollution levels. Swimming on the upper river is popular in the summer, and people bathe at Grantchester Meadows all year round. Hardy bathers take part in the New Year's Day swim. 3.What do we know about the River Cam according to the passage？

A、People dislike the recreational activities in River Cam.

B、Burbot was thought to be extinct in English waters since the early 1950s.

C、The last known burbot caught in Britain was in 1969, on the Cam.

D、The River Cam has no pollution.

听力原文：Man: Eggs are delicious food and parents have to make sure they are laid in spots well hidden from hungry thieves. One such careful parent braves the rushing waters of the Iguacu Waterfalls in South America to lay its eggs in a damp crack in the rock face behind the falling water. Accidents are frequent, but evidently the risk is considered worthwhile. In any case, there are no eggs on the menu in this particular part of South America, which is bad news for some!

听力原文： I want to talk today about some studies. They seem to indicate that there is a startling world-wide decline in the number of amphibians, such as flogs, toads and salamanders. There's little doubt that one reason why the number of amphibians is declining is their habitats have been destroyed when the developers fill in ponds and marshes to build houses. Amphibians can't just move somewhere. They need water to lay their eggs in. Another problem is the growing fish industry. Another range of popular pool fish such as carp have been introduced to many lakes and ponds all over the world. Raising and selling these fish can be profitable, but the fish eat the eggs and offspring of amphibians that were already living in the lakes and ponds. Other factors could be contributing to the decline include acid rain and the spread of pesticide residues. Many pesticides that farmers added to their crops are eventually washed away bythe rain and end upin pondsand other bodies of water where amphibians live. Amphibians are especially vulnerable to pesticides dissolved in the water because of their moist skins. Water can pass through amphibians allowing toxins dissolved in the water to enter the amphibians'body.

What does the speaker mainly discuss?

A．The distribution of different species of amphibians.

B．Possible reasons for reduction in the number of amphibians.

C．The effects of environmental change on the fish industry.

D．Guidelines for the responsible use of pesticides.
