We are so used to wearing shoes that few of us even think about them, apart from the times when we put them on and take them off. However, people didn't
always wear shoes. No one knows when people first
began to use them. It is reasonable to suppose that the
first shoes that covered feet were wrappings of animal
skins worn in cold climates. Sandals worn in southern
regions were most likely made of wood, with leather or
cloth attaching the soles to the upper part of the foot.
Over time, shoes became used not only for protection
but also for decoration. For example, high heels came
into fashion in the sixteen hundreds and were worn by
men. However uncomfortable they are, people have
continued to wear them for more than hundred years.
Today's shoes are relatively cheap because most are
designed by computer, and their components are cut by laser and sewn together by programmed machinery.

Lake Ontario is the smallest and the most eastern of the five Great Lakes. Although the lake is navigable for

large ships all year round, it is less traveled than the
other Great Lakes. The lake is about one hundred
ninety-three miles wide and covers an area of seven
thousand five hundred square miles. The shore of the lake approximately four hundred eighty miles around.
Two-thirds of the lake waters lie below sea level and.
because Lake Ontario is very deep, it does not freeze in
the u inter except near the shore w here tile water is
shallow A constant current carries the water from west
to east at the rate of about one-third of a mile per hour. Because of the capacity of large bodies of water to keep heat, the lake has a moderating effect on the climate of the areas that surround it. For example, while the eastern shore of the lake never has a really hot day, on its southern shore fruit trees grow. The lake empties
into the Atlantic Ocean through the St. Lawrence River,
while the Niagara River and the Welland Canal connect
it to Lake Erie in the southwest.
