问题     Do you remember all those years when scientists argued
that smoking would kill us but the doubters insisted that we
didn’t know for sure? That the evidence was inconclusive, the
science uncertain? That the antismoking lobby was to destroy our
way of lives and the government should stay out of the way? 【M1】______
Lots of Americans brought that nonsense, and over three decades, 【M2】______
some 10 million of smokers went to early graves. There are 【M3】______
upsetting parallels today, as scientists in one wave after another
try to awaken us against the growing threat of global warming. 【M4】______
The latest was a panel from National Academy of Sciences to tell 【M5】______
us that the Earth’s atmosphere is definitely warming and that the
problem is largely man-made. The clear message is that we
should get moving to protect us. Science never has all the answer. 【M6】______
But science does provide us with the best available guide to the
future. Just as on smoking, voice now come from many quarters
insisting that the science about global warming is complete, that 【M7】______
it’s OK to keep pouring fumes into the air until we know for sure.
This is a dangerous game: by the time 100 percent of the
evidence is in, they may be too late. With the risks obvious and 【M8】______
growing, a prudent people would take out an insuring policy now. 【M9】______
But it’s obvious that a majority of advisers don’t take global
warming seriously. Instead a plan of action, they continue to 【M10】______
press for more research — a classic of "paralysis by analysis."
【M8】
选项
答案they—it
解析 代词错误。从句子意义来看，这里的they指代不明。对比上一句，it’s OK tokeep pouring fumes into the air until weknow for sure，这里应该用it来指代to stoppouring fumes into the air。
