请问为什么用if 连接从句,用because可以吗?
People are learning the importance of doing more to keep their rivers clean if they want to enjoy the benefits of this natural resource.
答
从语法结构上来说用because似乎没有错,但逻辑上是不太妥当的.because后面跟的句子是前面某个结果的直接原因,比如：She didn't go to school today because she was ill..而本句作者想说的是如果人们希望能从自然资源中获得更多的益处的话,就得意识到得做更多的事情去保持河流清洁的重要性.
