   台湾籍旅美老师今天交给我们的句子是:


  Soft tissue, on the other hand, isn't as dense 1, and contains mostly lower atomic number elements, like carbon, hydrogen, and oxygen. So more of the X-rays penetrate 2 tissues like lungs and muscles, darkening the film.
  相反的,软组织不是那么致密,大部分含有较低原子序数的元素,如碳、氢及氧。所以比较多的X-射线能穿透如肺及肌肉组织,使底片变得较黑。

a.密集的,稠密的,浓密的;密度大的
  • The general ambushed his troops in the dense woods. 将军把部队埋伏在浓密的树林里。
  • The path was completely covered by the dense foliage. 小路被树叶厚厚地盖了一层。
v.透(渗)入;刺入,刺穿;洞察,了解
  • Western ideas penetrate slowly through the East.西方观念逐渐传入东方。
  • The sunshine could not penetrate where the trees were thickest.阳光不能透入树木最浓密的地方。
