第339句
But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions.
译文:但是科学确实为我们的未来提供了最可靠的指引,关键是我们的国家和世界其他各国在做重要决策时,应该以科学能够提供给我们的、关于人类目前的行为对未来影响的最佳判断作为依据。
点睛:本句是个并列句,由and连接两个并列分句。前一分句的主干是science... provide us with…guide;后一分句的主干是it is critical+ that引导的从句,其中it为形式主语,真正的主语是that从句。主语从句的主干为our nation and the world base…policies on…judgments…,其中judgments后接有两个定语:一是定语从句that science can provide,二是现在分词结构concerning the future consequences of present actions作后置定语。provide sb. with sth.意为“向某人提供某物”,也可以说provide sth. for sb.。
The government provided much food for the poor.
政府向穷人提供了许多食物。
The Red Cross provided the victims with some good medicine.
红十字会向受害者提供了许多好的药品。
注意, provided/providing是连词,表示“在…的条件下;如果”,相当于“on the condition;if”。
