大家好， 文章背景(写在其他段)是说联准会蒐集资料来阐述利率和银行准备金及银行借贷多寡的 关系。 段落如下： Banks in our sample held about 60 percent of total reserves as of December 2018. On average, the ratio of bank reserves to total assets is 4 percent. Also, total loans make up near two-thirds of our sample banks' total assets, and loans held by our sample banks constitute a material fraction of total loans extended by commercial banks. -------- 试译 -------- 样本银行在２０１８年持有总储备的６０％。平均每个银行储备和总资产比例是４％。 并且总贷款余额占了样本银行总资产将近三分之二，样本银行持有的贷款也构成商业 银行总展期贷款的一小部分。 -------- 问题 -------- * 最後一句的 a material fraction of 的 material 应该要怎麽理解，实体的一部份？ 听起来有点多余，可以去掉吗？ -------- 备注 -------- 类似的句子还有 "The flip side is a material fraction of households will come out of the crisis with stronger balance sheets than they went in, bc workers in them are still employed, or are getting 100%+ of income replaced by UI, and have spent less. They will have capacity to spend." 另一方面是一部分的家庭相比於危机前，在走出危机时会有更强的资产负债表，因为在 危机时他们没有被裁员，或是补助大於他们原本的薪资，并且花费的更少。他们将有消费 的能力。 The surprising finding is that a material fraction of seemingly‘middle class’Americans also judge themselves to be financially fragile. 令人惊讶的发现是一部分被视为"中产阶级"的美国人也自认财务上并不健全。 感谢各位的回答，谢谢大家。 -- --
