The researchers’ report said, “while more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”（你的原句researchers 拼写有误）

【翻译】研究人员的报告说，“虽然笔记越多越有益，但如果这些笔记是随意写的，对于笔记本电脑来说更有可能的情况是，益处就没有了。”

【分析】该句的难点是直接引语部分。

1. “while more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”  为宾语从句。

2. 宾语从句本身是一个复杂的复合句。

while more notes are beneficial 是让步状语从句，while 放在句首可以表示让步，等于though。

if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears. 是主句。

3. 在主句中，if the notes are taken mindlessly 是条件从句；之后的 as is more likely the case on a laptop, the benefit disappears 是主句。

4. 在as is more likely the case on a laptop, the benefit disappears 中，the benefit disappears 是主句。as is more likely the case on a laptop 是定语从句，as 是关系代词指代主句整个内容：the benefit disappears（益处没有了）。
