The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars.

　　在分析这个长难句之前，考生可以尝试着按我们之前分析长难句的步骤拆解一下这个句子，只有将句子拆解到位，考生才能够真正的理解句子。许多考生在分析句子的时候模棱两可，考生每一次在学习中的拖沓和偷懒都将会成为自己复习路上的一个又一个的难题。因此，考生切勿在复习过程中为自己搬石头砸脚。那么，接下来我们就来把这个句子具体的来分析下：

　　（1）The issue of //whether life ever existed on the planet, and whether it persists to this day, //has been highlighted //by mounting evidence //that the Red Planet once had abundant stable, liquid water and //by the continuing controversy over suggestions //that bacterial fossils rode to Earth on a meteorite from Mars.

　　（2）The issue of A and B has been highlighted by C and D.

　　（3）The issue of whether life ever existed on the planet has been highlighted by C and D

　　（4）The issue of whether it persists to this day has been highlighted by C and D

　　（5）by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars.

　　在这个句子中嵌套了两处平行结构，即 A and B has been highlighted by C and D，在搞清楚句式结构后，句子的汉语意思将会很容易得出，即：越来越多的证据表明，这个红色行星上曾经有稳定而丰富的液态水，而且人们对从火星落到地球上的细菌化石陨石的说法一直有争论，使火星上是否存在过生命和是否至今仍有生命的问题成为了引人注目的重点。A和B两处可以视为of 后的宾语部分，即两个并列的宾语从句，C和D则是并列的两个同位语从句，即evidence that和suggestions that，这样一来，是不是句子的结构就更容易理解了呢？
