--- Lesson 90 What's for supper? |
[00:05.840] |
--- First listen and then answer the question. |
[00:11.800] |
--- What kind of fish are they? |
[00:16.840] |
Fish and chips has always been a favourite dish in Britain, |
[00:21.800] |
but as the oceans have been overfished, fish has become more and more expensive. |
[00:28.120] |
So it comes as a surprise to learn that giant fish are terrifying the divers on North Sea oil rigs. |
[00:36.960] |
Oil rigs have to be repaired frequently and divers, who often have to work in darkness a hundred feet under water, |
[00:46.920] |
have been frightened out of their wits by giant fish bumping into them as they work. |
[00:54.720] |
Now they have had special cages made to protect them from these monsters. |
[01:00.560] |
The fish are not sharks or killer whales, |
[01:04.400] |
but favourite eating varieties like cod and skate which grow to unnatural sizes, sometimes as much as twelve feet in length. |
[01:16.240] |
Three factors have caused these fish to grow so large: |
[01:20.720] |
the warm water round the hot oil pipes under the sea; |
[01:25.720] |
the plentiful supply of food thrown overboard by the crews on the rigs; |
[01:31.480] |
the total absence of fishing boats around the oil rigs. |
[01:35.680] |
As a result, the fish just eat and eat and grow and grow in the lovely warm water. Who eats who? |
