16.众所周知,大量砍树对自然平衡有灾难性的影响.(As)As we all know/As is known to all,cutting down a large number of trees has disastrous effects on the balance of nature..分析 As we all know/As is known to all,cutting down a large number of trees has disastrous effects on the balance of nature.
解答 As we all know/As is known to all,cutting down a large number of trees has disastrous effects on the balance of nature.
这里是介绍的一个基本道理,所以用一般现在时.根据句意"众所周知"可知运用as引导的非限制性定语从句,后面的主句用动名词短语作主语.
As we all know/As is known to all 众所周知;cut down 砍伐、砍到,the balance of nature 自然平衡.
点评 对于as引导的非限制性定语从句要掌握一些基本的表达方式;如:
as is often the case(这是常有的事),as was expected(不出所料),as often happens(正如经常发生的那样),as is known to all(众所周知),as has been said before(如上所述),as is mentioned above(正如上面所提到的)等.
