Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.

译：宇宙膨胀说虽然听似奇特，但是它是基本粒子物理学中一些公认的理论所产生的在科学上看来似乎可信的结论。许多天体物理学家近十年中大部分时间都确信这一论说是正确的。

1. Odd though it sounds 为though引导的让步状语从句，形式上为倒装形式;正常形式为：Though it sounds odd， 译为：宇宙膨胀说虽然听似奇特。其中it指后面的cosmic inflation (宇宙膨胀说)。

2. 句子主干为“and”连接的并列结构，前半句主干为cosmic inflation/ is /a scientifically plausible consequence of some respected ideas; 介词短语in elementary particle physics充当状语。

3. 后半部分主干为many astrophysicists have been convinced that it is true;介词短语for the better part of a decade 充当时间状语。
