2个句子的辨析as the earth cooled down,water began to appear on its
3个回答

随着地球冷却下来,水开始出现在其表面.

as the earth cooled down,water began to appear on its surface.

——从语法角度说,更易理解,也是由as 引导的从句,是复合句,自然前后都是句子.所以用过去时.clooled

而下面这句,是with引导的伴随结构,是个分词结构——不要忘了,一个句子,只能有一个谓语动词,其它的,都要改成或分词,或不定式等形式.

下面不是复合句,而不一个简单句.

with the earth cooling down,water began to appear on its surface.

地球降了温,水就开始出现在其表面.

OK?

知识在于点滴积累,更在于不懈努力.
