1．S whether life will cntinue n the earth fr millins f years t cme will depend n whether this prblem can be slved.
whether与if引导名词性从句时的区别：(1)whether可以直接与r nt连用，if不可以。(2)引导位于句首的主语从句，用whether，不用if。(3)引导表语从句和同位语从句，用whether，不用if。(4)动词不定式之前用whether，不用if。(5)介词之后的宾语从句用whether，不用if。

本句中的twice as ...表示“是……的几倍”，该句型中的twice也可用half, ne­third等词，表示“是……的一半/几分之几”。
2．But when I tried t step frward, I fund I was carried twice as far as n the earth and fell ver.而当我试着向前迈步的时候，我发觉我被送出去很远，步子的跨度竟是在地球上的两倍，因而我摔倒了。
有关倍数的表达方式还有：①倍数＋as＋adj./adv.＋as ...②倍数＋形容词/副词的比较级＋than ...③倍数＋the＋名词＋f ...
(1)在“倍数＋the＋名词＋f”结构中，常用的名词有size, height, weight, length, width等。(2)两倍用twice或duble，不到一倍用分数表示，三倍或三倍以上一般用times来表示，如three times, fur times等。
