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] 【C2】
选项
答案 L
解析 由语法结构可知，该题应填入一个名词作主语，而且由于系动词为单数is故该名词一定为单数名词或不可数名词。选项中符合这一要求的有E)evidence，L)consensus和O)concern。由下文中...that much of that change has been driven by us可以推断主语一定是表示“观点或见解”的词，这样才可与上文中提到的“过去气候的变化主要原因是自然力量”相呼应。很显然答案E)和())填在此处都会导致语意不通。
