Apparently Massive Stars Manage Lose Sufficient Material Masses

意群训练： Apparently most massive stars manage to lose sufficient material that their masses drop below the critical value of 1.4 M ⊙ before they exhaust their nuclear fuel .

标志： Apparently most massive stars manage to lose sufficient material so that their masses drop below the critical value of 1.4 M⊙ /before they exhaust their nuclear fuel./

译文： 显然，大多数的巨星 能够 失去足够多 的物质以致于 /在燃尽其核燃料以前/它们的质量下降到关键值1.4 M⊙ 以下。

解释： 我们中国考生容易习惯性的把that以及其后的内容看成了一个定语从句来修饰material，但是这样读下来发现意思不通，于是发生思维混乱，大脑拒绝工作，以致当场晕厥。

原文相当于在that 之前省略了so ，引导一个表目的的状语从句。事实上that本身有这种做连接词的用法，相当于so that或in order that。例如：Speak loud that everybody may hear what you say。
