问题      For millions of years, the changes in Earth’s climate have been driven by forces of nature. But for the last century and a half, Earth’s average temperature has been rising【C1】______ than any time in the past ten thou- sand years. The【C2】______ in science is that much of that change has been driven by us.The climate is not what it used to be. It’s not your grandfather’s climate anymore.
     The【C3】 ______ are everywhere: droughts in the American Southwest and Africa’s Sahara(撒哈拉),【C4】______ seas in Louisiana and Bangladesh (孟加拉国), tropical diseases spreading north and extremes of weather from Florida to France.
     There are people who still say global warming needn’t【C5】______ us. If it’s happening at all, it’s a natural trend, not much we can do about it. But there is now hard【C6】______ which shows that the warming is not only real. It’s【C7】______ . It’s altering the climate’s most basic elements like rainfall and evaporation, days of sunshine and nighttime temperatures. Those changes are【C8】______   the environments in the agricultural production,【C9】______ wild species with extinction and putting at risk our life styles, our health, and some of our favorite cities by the sea. We’ll follow the signs and see who i f anyone is responsible. We’ll meet scientists who are【C10】______ new climate evidence and we’ll see what we can do to help.
   A) worry            F) signs           K) faster
   B) rising           G) vast            L) consensus
   C) troubles         H) investigating   M) threatening
   D) quickly          I) dangers         N) damaging
   E) evidence         J) accelerating    O) concern [br] 【C9】
选项
答案 M
解析 从语法结构看，这里与54题一样缺少动词，因为下文中表并列的连接词and后的动词为putting，由此可判断前面的动词也应与putting的形式保持一致，也应该使用现在时。选项中符合此意的单词有M) threatening，N)damaging和H)investigating。H)investigating在此处语意不通，threaten wild species with extinction搭配，意思是“让野生动物濒临灭绝的边缘”。
