句子：Since a lot of water is getting held up by the barrage, the incoming tides wont go as high, but they wouldnt be as low during low tide, either.
问题1：请问老师，句子里的as high和as low如何理解，as是程度副词“同样地”吗？as作表示程度“同样地”的时候是否只能在“as...as...”句型里呢？
问题2：句子在since缘由从句里用的is getting held up进行时，这里我理解是表以后，主句部分的wont还是以后时，但but后的并列句却成了wouldnt，那样这个would如何理解啊？
Since a lot of water is getting held up by the barrage, the incoming tides wont go as high, but they wouldnt be as low during low tide, either.
【翻译】因为很多的水被堤坝阻挡住，潮水不会涨到那样高，但在低潮时也不会那样低。
【剖析】won’t和wouldn’t 两个情态动词，都表示“推断”。前者推断的可能性比后者要大一些，wouldn’t 不表示过去的意思。
两个as 都是程度副词，意为“那样；这样”，否定时可用so 代替。后面省略了已知的比较成分as...，具体省略了什么，前文肯定提及，比如 as we imagine “跟大家想象的一样...”。
