课下作业（二） 话题阅读培优练
Ⅰ.根据提示填空
?Due_to (由于) climate changes, Arctic ice is breaking up earlier in the spring, and its area ?is_decreasing (decrease). This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets ?floating (float) on the ocean. But as the ice has melted, the polar bears have been forced ?to_spend(spend) more time on land. There, they have begun to frequent beaches, feeding on the remains of whales ?caught(catch) by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking (减少) ice has also forced ?more (much) polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of ?drowned (drown) polar bears have been observed.Unless the bears can learn to survive these climate changes, these giants of the ice may one day ?disappear (appear)．

The head of the research team, Christ Thomas, who is a professor of conservation biology at Leeds University, said the results of their research were ?frightening. More than 10% of all plants and animals will disappear from the earth. It is too late to save many plants and animals ?because_of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we can save many more plants and animals from ?disappearing. The scientists studied some areas of the world with very rich biology. These areas were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had ?a_better_chance_of survival because they could move uphill to get cooler.

Ⅰ.阅读理解
A
Al Gore has been concerned with climate change, or ‘climate crisis’ as he calls it, for the majority of his political career. As the years passed and he became more passionate about this issue, he started travelling the world in order to educate people about the effects of global warming using computer slide shows. Free of charge, he explained to his audiences that the world is facing a ‘planetary emergency’ and that it isn't too late to stop it if appropriate action is taken now.
It was during this time of touring and giving lectures that Gore was by Hollywood producer Laurie David, who asked him to turn his slide into a documentary in which he would play the starring role. At first, was reluctant,_as he has always been a very private person, despite being being in the public eye. Eventually, though, David managed to persuade The result was a fascinating documentary combining references to own life story with horrifying predictions about the future of our planet.
Little did Gore know that just one year later he would be walking along the red carpet at the Cannes Film Festival and later collecting an Oscar for ‘Best Documentary’. Advertised as ‘the scariest movie you'll see，’ the movie concentrates on the potentially terrifying consequences of climate change.
‘An Inconvenient Truth’ certainly gives us much to consider. As the title of the film suggests, it may be inconvenient for us to have to think about the future of the planet, but think we must.
The profits from the film are now funding other campaigns to spread the message about global warming. Gore is delighted that some schools are even using the DVD to help them teach awareness of environmental issues to their students.
So can this one man's efforts really make a difference? Well, according to Gore, if we are clear about what the problem is, then we are more likely to introduce changes into our daily lives. It may not seem as if the decisions of individuals can achieve very much, but put them all together and they may add up to something that will, literally, change the world.
