Lesson 7－Part 2
For a long time, /
swimwear designers have been working hard /
to make wear /
that can help swimmers win their races. //
The designers thought and thought /
about how humans could swim like fish. //
They finally made a new type of swimwear. //
It was made of a new material /
similar to shark skin. //
More than half of the swimmers wore it /
in the 2000 Olympics. //
Thanks to many fine lines on the material, /
one can swim faster through the water. //
After this, /
other kinds of swimwear were made /
by learning from different creatures. //
Fish and birds are some examples. //
The designers studied /
how these creatures entered the water /
or moved in it. //
Their main aim was /
to create materials and design shapes /
that reduce water resistance. //
As a result, /
many swimmers broke world records. //
