Sherlock Holmes.(named)

Ask Ss, “ Has any one of you been to
the seaside? What can you do there? ”
Step III---Dialogue
1.Presentation
BACKGROUND KNOWLEDGE
The sea contains a large number of substances,
besides common salt. If you boiled away
some sea-water, you would find more than
forty different materials. For example,
out of a cubic mile of water you would
get ninety-four tons of silver and three
tons of gold! It would cost more to get
these precious metals than they are worth.
But the sea provides us with a great many
materials which we can get easily and
which we use a lot. For instance, we use
huge quantities of sand in industry to
make glass detergents（洗涤剂） and cement（水泥）.
Besides materials like salt and sand,
we obtain a great deal of food from the
sea.

that make up the salt water of the oceans,
including salt.)

of water as the sea loses a lot of water
to the air.)
