第14课时　八年级(下) Units 7～8

Ⅰ.阅读理解(2024汕头二模)

Glaciers(冰川) hold about 70% of the Earth's fresh water.They are large pieces of closely packed ice and snow.Glaciers only form in places where it is very cold.Every year, new snow falls on top of the old snow.The layers (层) of snow press down on each other, and then the snow crystals(晶体) start to change.They get smaller, and air pockets are pushed out of the snow.This allows the crystals to grow longer.Over time, the snow layer at the bottom of all the other snow layers becomes ice.The whole process of making a glacier takes about 100 years.

Some ice is packed so closely that it looks like it is blue.The snow on top of a glacier looks white because it reflects all of the light.But the ice layers of the glacier do not have many air pockets.They absorb different parts of light and reflect blue light.

Some of the glaciers on the Earth may be very old.Scientists think that a few glaciers have ice that is about 8 million years old.Not all of the glaciers are that old, though.A number of glaciers in Alaska(阿拉斯加) are only about 100 years old.

There are different kinds of glaciers.An ice stream is a kind of glacier that forms on another glacier, and it looks like a frozen river.Rock glaciers are made when ice, rock and other objects get mixed together.
