Question

谁能帮我详细的讲解一下这句英语的翻译和语法分析？

The primary end points were
progression-free survival (reported previously) and overall survival among patients whose tumors expressed PD-L1 with a CPS of10 or more (the CPS10 subgroup), among patients whose tumors expressed PD-L1 with a CPS of1 or more (the CPS-1 subgroup), and in the intention-to-treat population.

Answer 1

这个句子的翻译为：

主要终点是在肿瘤细胞表达的PD-L1 CPS值高于或等于10（CPS10亚组），PD-L1 CPS值高于或等于1（CPS-1亚组）以及意向治疗人群中的总生存期和进展期无疾病生存期（之前已经报道过PD-L1进展无疾病生存期）。

这个句子的语法分析如下：

• "The primary end points were progression-free survival (reported previously) and overall survival"：主语是"the primary end points"（主要终点），谓语动词是"were"（表示过去时态的"be"动词），其中还包括两个主语补语，分别是"progression-free survival"（无进展生存期）和"overall survival"（总生存期）。

• "among patients whose tumors expressed PD-L1 with a CPS of10 or more (the CPS10 subgroup), among patients whose tumors expressed PD-L1 with a CPS of1 or more (the CPS-1 subgroup), and in the intention-to-treat population"：这是名词性短语做介词短语的补语，介词是 "among"，主语是"patients"（患者），修饰"patients"的是两个定语从句和"in the intention-to-treat population"这个介词短语。其中，"whose tumors expressed PD-L1"是定语从句，修饰"patients"，意思是"肿瘤细胞表达PD-L1的患者"；"with a CPS of10 or more"是另外一个定语从句，修饰"PD-L1"，意思是"PD-L1 CPS值高于或等于10"，类似的，"with a CPS of1 or more"是另外一个定语从句，修饰"PD-L1"，意思是"PD-L1 CPS值高于或等于1"。

• "in the intention-to-treat population"：介词短语，修饰"the primary end points"，意思是"意向治疗人群中的"。
