Ⅱ.阅读理解(共5小题；每小题2分，满分10分)

Besides fish，the whale is hunted for its flesh and blubber as well as its bones.Whale hunting is a dangerous job because the whale is not a fish in the real sense and it can destroy a boat if it strikes.A whole novel Moby Dick has been dedicated to
whale hunting.
The floor of the sea has not been exploited.There is a belief that the deep floors of the sea must be rich in minerals.When the minerals on the land is exhausted，perhaps man may turn to the sea bed for resources.There is，of course，mineral oil found in some places in the sea bed.Already some countries have taken up the idea and have started prospecting for oil in the sea.
If the harvest of the sea is understood in a wider sense，water transport then can also be the bloodstream of the world's commerce.Wide arteries(干道)of shipping lines have liners loaded with the world's goods.Till the invention of the airplane the ship was the only link connecting countries divided by the seas.
Another important item of harvest is the energy that could be produced by using the tidal waves.There are countries where these tidal waves may bring harm.But they could be used to produce power.This possibility has not been ruled out and there are attempts ready to get this source.
