Exercise
There is little doubt that Earth is getting warmer and warmer. In 2013, many people __1__ (shock) by a news photo of a dead polar bear which appeared to have starved and died. Experts claimed that low sea-ice levels __2__ (cause) by climate change meant the bear could not hunt seals as before, so it had to travel greater distances __3__ (find) food. Then what is causing the increase in the global average surface temperature Climate scientists often mention a key climate process called the “greenhouse effect”， __4__ has two common meanings：the “natural” greenhouse effect and the “man-made” greenhouse effect. The “man-made” greenhouse effect has now become __5__ big problem. There is strong and comprehensive evidence that the rise in temperature has led __6__ an increase in extreme weather and natural disasters worldwide. In fact, news reports are __7__ (frequent) broadcast about extreme rainstorms and heatwaves __8__ (cause) deaths and economic losses. This requires the attention of people all over the world. We as individuals can reduce our “carbon footprint” by __9__ (restrict) the amount of carbon dioxide our lifestyles produce. It is our responsibility __10__ (seize) every opportunity to educate everyone about global warming.
