三、语法填空 阅读下面短文, 在空白处填入一个适当的单词或括号内单词的正确形式。
With the rise of human civilization about 8,000 years ago and especially 1 the
Industrial Revolution in the mid-1700s, human beings began to alter (改变) the surface, water, and atmosphere of the Earth. In doing so, 2 have become active geological agents, not
unlike other forces of change that influence the planet. As a result, Earth’s immediate future
depends, 3 a great extent, on the 4 (behave) of human beings. For example, 5
widespread use of fossil fuels is releasing carbon dioxide and other greenhouse gases into the
atmosphere and 6 (threat) to warm the planet’s surface. This global warming could
melt glaciers and the polar ice caps, 7 could flood coastlines around the world and many
island nations. In effect, the carbon dioxide that 8 (remove) from Earth’s early
atmosphere by the oceans and by primitive plant and animal life, 9 subsequently (随后)
buried as fossilized remains in sedimentary rock, is being released back into the atmosphere
and is threatening the 10 (exist) of living things.
